General Information About Cervical Cancer

Cervical cancer is the fourth most common cancer in women worldwide, and it has the fourth highest mortality rate among cancers in women.[1] Most cases of cervical cancer are preventable with routine screening and treatment of precancerous lesions. As a result, most cervical cancer cases are diagnosed in women who live in regions with inadequate screening protocols.

Incidence and Mortality

Estimated new cases and deaths from cervical (uterine cervix) cancer in the United States in 2024:[2]

• New cases: 13,820.
• Deaths: 4,360.

Anatomy

The uterine cervix is contiguous with the uterine body, and it acts as the opening to the body of the uterus. The uterine cervix is a cylindrical, fibrous organ that is an average of 3 to 4 cm in length. The portio of the cervix is visible on vaginal inspection. The opening of the cervix is termed the external os. The os is the beginning of the endocervical canal, which forms the inner aspect of the cervix. At the upper aspect of the endocervical canal is the internal os, a narrowing of the endocervical canal. The narrowing marks the transition from the cervix to the uterine body. The endocervical canal beyond the internal os is termed the endometrial canal.

The cervix is lined by two types of epithelial cells: squamous cells at the outer aspect and columnar, glandular cells along the inner canal. The transition between squamous cells and columnar cells is an area termed the squamocolumnar junction. Most precancerous and cancerous changes arise in this zone.

Pathogenesis

Cervical carcinoma begins at the squamocolumnar junction. It can involve the outer squamous cells, inner glandular cells, or both. The precursor lesion is dysplasia: cervical intraepithelial neoplasia (CIN) or adenocarcinoma in situ, which can subsequently become invasive cancer. This process can be quite slow. Longitudinal studies have shown that in patients with untreated in situ cervical cancer, 30% to 70% will develop invasive carcinoma over a period of 10 to 12 years. However, in about 10% of patients, lesions can progress from in situ to invasive in less than 1 year. As it becomes invasive, the tumor breaks through the basement membrane and invades the cervical stroma. Extension of the tumor in the cervix may ultimately manifest as ulceration, exophytic tumor, or extensive infiltration of underlying tissue, including the bladder or rectum.

Risk Factors

Increasing age is the most important risk factor for most cancers. The primary risk factor for cervical cancer is human papillomavirus (HPV) infection.[3,4,5,6]

Other risk factors for cervical cancer include the following:

• High parity and HPV infection.[7]
• Smoking cigarettes and HPV infection.[8]
• Long-term use of oral contraceptives and HPV infection.[9,10]
• Immunosuppression.[11,12]
• Having first sexual encounter at a young age.[13]
• High number of sexual partners.[13]
• Exposure to diethylstilbestrol (DES) in utero.[14]

Human papillomavirus (HPV) infection

HPV infection is a necessary step in the development of virtually all precancerous and cancerous lesions. Epidemiological studies convincingly demonstrate that the major risk factor for development of preinvasive or invasive carcinoma of the cervix is HPV infection, far outweighing other known risk factors.

More than 6 million women in the United States are estimated to be infected with HPV. Transient HPV infection is common, particularly in young women,[15] while cervical cancer is rare. The persistence of an HPV infection leads to increased risk of developing precancerous and cancerous lesions.[16,17]

The strain of HPV infection is also important in conferring risk. Multiple subtypes of HPV infect humans; subtypes 16 and 18 have been most closely associated with high-grade dysplasia and cancer. Studies suggest that acute infection with HPV types 16 and 18 conferred an 11-fold to 16.9-fold risk of rapid development of high-grade CIN.[18,19,20] Further studies have shown that infection with either HPV 16 or 18 is more predictive than cytological screening of high-grade CIN or greater disease, and that the predictive ability is seen for up to 18 years after the initial test.[21,22,23]

There are two commercially available vaccines that target anogenital-related strains of HPV. The vaccines are directed toward HPV-naïve adolescents and young adults. Although penetration of the vaccine has been moderate, significant decreases in HPV-related diseases have been documented.[24] For more information, see Cervical Cancer Prevention.

Clinical Features

Early cervical cancer may not cause noticeable signs or symptoms.

Possible signs and symptoms of cervical cancer include the following:

• Vaginal bleeding.
• Unusual vaginal discharge.
• Pelvic pain.
• Dyspareunia.
• Postcoital bleeding.

Diagnosis

The following procedures may be used to diagnose cervical cancer:

• History and physical exam.
• Pelvic exam.
• Cervical cytology (Pap smear).
• HPV test.
• Endocervical curettage.
• Colposcopy.
• Biopsy.

HPV testing

Cervical cytology (Pap smear) has been the mainstay of cervical cancer screening since its introduction. However, molecular techniques for the identification of HPV DNA are highly sensitive and specific. Current screening options include the following:

• Cytology alone.
• Cytology and HPV testing.

HPV testing is suggested when it is likely to successfully triage patients into low- and high-risk groups for a high-grade dysplasia or greater lesion.

HPV DNA tests are unlikely to separate patients with low-grade squamous intraepithelial lesions into those who do and those who do not need further evaluation. A study of 642 women found that 83% had one or more tumorigenic HPV types when cervical cytological specimens were assayed by a sensitive (hybrid capture) technique.[25] The authors of the study and an accompanying editorial concluded that using HPV DNA testing in this setting does not add sufficient information to justify its cost.[25]

HPV DNA testing has proven useful in triaging patients with atypical squamous cells of undetermined significance to colposcopy and has been integrated into current screening guidelines.[25,26,27]

Other studies show that patients with low-risk cytology and high-risk HPV infection with types 16, 18, and 31 are more likely to have CIN or microinvasive histopathology on biopsy.[18,28,29,30] One method has also shown that integration of HPV types 16 and 18 into the genome, leading to transcription of viral and cellular messages, may predict patients who are at greater risk of high-grade dysplasia and invasive cancer.[31]

For women older than 30 years who are more likely to have persistent HPV infection, HPV typing can successfully triage women into high- and low-risk groups for CIN 3 or worse disease. In this age group, HPV DNA testing is more effective than cytology alone in predicting the risk of developing CIN 3 or worse.[32] Other studies have shown the effectiveness of a primary HPV DNA–screening strategy with cytology triage over the previously used cytology-based screening algorithms.[33,34]

Prognostic Factors

The prognosis for patients with cervical cancer is markedly affected by the extent of disease at the time of diagnosis. More than 90% of cervical cancer cases can be detected early by using the Pap test and HPV testing.[35] Pap and HPV testing are not performed on approximately 33% of eligible women, which results in a higher-than-expected death rate.

Clinical stage

Clinical stage as a prognostic factor is supplemented by several gross and microscopic pathological findings in surgically treated patients.

Evidence (clinical stage and other findings):

In a large, surgicopathological staging study of patients with clinical stage IB disease reported by the Gynecologic Oncology Group (GOG) GOG-49, the factors that most prominently predicted lymph node metastases and a decrease in disease-free survival were capillary-lymphatic space involvement by tumor, increasing tumor size, and increasing depth of stromal invasion, with the latter being the most important and reproducible.[36,37]

In a study of 1,028 patients treated with radical surgery, survival rates correlated more consistently with tumor volume (as determined by precise volumetry of the tumor) than with clinical or histological stage.[38]

A multivariate analysis of prognostic variables in 626 patients with locally advanced disease (primarily stages II, III, and IV) studied by the GOG identified the following variables that were significant for progression-free interval and survival:[39]

• Periaortic and pelvic lymph node status.
• Tumor size.
• Patient age.
• Performance status.
• Bilateral disease.
• Clinical stage.

The study confirmed the overriding importance of positive periaortic nodes and suggested further evaluation of these nodes in locally advanced cervical cancer. The status of the pelvic nodes was important only if the periaortic nodes were negative. This was also true for tumor size.

It is controversial whether adenocarcinoma of the cervix carries a significantly worse prognosis than squamous cell carcinoma of the cervix.[40] Several population-based and retrospective studies showed a worse outcome for patients with adenocarcinoma, with an increase in distant metastasis compared with those with squamous histology.[41,42,43,44] Reports conflict about the effect of adenosquamous cell type on outcome.[45,46] One report showed that approximately 25% of apparent squamous tumors have demonstrable mucin production and behave more aggressively than their pure squamous counterparts, suggesting that any adenomatous differentiation may confer a negative prognosis.[47]

In a large series of cervical cancer patients treated by radiation therapy, the incidence of distant metastases (most frequently to the lung, abdominal cavity, liver, and gastrointestinal tract) was shown to increase as the stage of disease increased, from 3% in stage IA to 75% in stage IVA.[48] A multivariate analysis of factors influencing the incidence of distant metastases showed stage, endometrial extension of tumor, and pelvic tumor control to be significant indicators of distant dissemination.[48]

GOG studies have indicated that prognostic factors vary depending on whether clinical or surgical staging is used and with different treatments. Delay in radiation delivery completion is associated with poorer progression-free survival when clinical staging is used. Stage, tumor grade, race, and age are uncertain prognostic factors in studies using chemoradiation.[49]

Other prognostic factors

Other prognostic factors that may affect outcome include the following:

• HIV status: Women with HIV have more aggressive and advanced disease and a poorer prognosis.[50]
• C-myc overexpression: A study of patients with known invasive squamous carcinoma of the cervix found that overexpression of the C-myc oncogene was associated with a poorer prognosis.[51]
• Number of cells in S phase: The number of cells in S phase may also have prognostic significance in early cervical carcinoma.[52]
• HPV-18 DNA: HPV-18 DNA is an independent adverse molecular prognostic factor. Two studies have shown a worse outcome when HPV-18 was identified in cervical cancers of patients undergoing radical hysterectomy and pelvic lymphadenectomy.[53,54]
• A polymorphism in the Gamma-glutamyl hydrolase enzyme, which is related to folate metabolism, has been shown to decrease response to cisplatin, and as a result is associated with poorer outcomes.[55]

Follow-Up After Treatment

High-quality studies are lacking, and the optimal follow-up for patients after treatment for cervical cancer is unknown. Retrospective studies have shown that cancer recurrence is most likely within the first 2 years.[56] As a result, most guidelines suggest routine follow-up every 3 to 4 months for the first 2 years, followed by evaluations every 6 months. Most recurrences are diagnosed secondary to new patient symptoms and signs,[57,58] and the usefulness of routine testing, including a Pap smear and chest x-ray, is unclear.

Follow-up should be centered around a thorough history and physical examination with a careful review of symptoms. Imaging should be reserved for evaluation of a positive finding. Patients should be asked about possible warning signs, including the following:

• Abdominal pain.
• Back pain.
• Painful or swollen leg.
• Problems with urination.
• Cough.
• Fatigue.

The follow-up examination should also screen for possible complications of previous treatment because of the multiple modalities (surgery, chemotherapy, and radiation) that patients often undergo during their treatment.

Cellular Classification of Cervical Cancer

Squamous cell (epidermoid) carcinoma makes up approximately 90% of cervical cancers, and adenocarcinoma makes up approximately 10% of cervical cancers. Adenosquamous and small cell carcinomas are relatively rare. Primary sarcomas of the cervix and primary and secondary malignant lymphomas of the cervix have also been reported.

Stage Information for Cervical Cancer

Carcinoma of the cervix can spread via local invasion, the regional lymphatics, or bloodstream. Tumor dissemination is generally a function of the extent and invasiveness of the local lesion. While cancer of the cervix generally progresses in an orderly manner, occasionally a small tumor with distant metastasis is seen. For this reason, patients must be carefully evaluated for metastatic disease.

Pretreatment surgical staging is the most accurate method to determine the extent of disease,[1] but there is little evidence to demonstrate overall improved survival with routine surgical staging; the staging is usually performed only as part of a clinical trial. Pretreatment surgical staging in bulky but locally curable disease may be indicated in select cases when a nonsurgical search for metastatic disease is negative. If abnormal nodes are detected by computed tomography (CT) scan or lymphangiography, fine-needle aspiration should be negative before a surgical staging procedure is performed.

Tests and procedures to evaluate the extent of the disease include the following:

• CT scan.
• Positron emission tomography scan.
• Cystoscopy.
• Laparoscopy.
• Chest x-ray.
• Ultrasonography.[2]
• Magnetic resonance imaging.[2]

FIGO Stage Groupings and Definitions

The Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) and the American Joint Committee on Cancer have designated staging to define cervical cancer; the FIGO system is most commonly used.[3,4]

Table 1. Definitions of FIGO Stage I^a

Stage	Description	Illustration
FIGO = Fédération Internationale de Gynécologie et d'Obstétrique.
a Adapted from FIGO Committee for Gynecologic Oncology.[3]
b Imaging and pathology can be used, when available, to supplement clinical findings with respect to tumor size and extent, in all stages. Pathological findings supersede imaging and clinical findings.
c The involvement of vascular/lymphatic spaces should not change the staging. The lateral extent of the lesion is no longer considered.
I	The carcinoma is strictly confined to the cervix (extension to the corpus should be disregarded).
IA	Invasive carcinoma that can be diagnosed only by microscopy, with maximum depth of invasion ≤5 mm.b
–IA1	–Measured stromal invasion ≤3 mm in depth.
–IA2	–Measured stromal invasion >3 mm and ≤5 mm in depth.
IB	Invasive carcinoma with measured deepest invasion >5 mm (greater than stage IA); lesion limited to the cervix uteri with size measured by maximum tumor diameter.c
–IB1	–Invasive carcinoma >5 mm depth of stromal invasion and ≤2 cm in greatest dimension.
–IB2	–Invasive carcinoma >2 cm and ≤4 cm in greatest dimension.
–IB3	–Invasive carcinoma >4 cm in greatest dimension.

Table 2. Definitions of FIGO Stage II^a

Stage	Description	Illustration
FIGO = Fédération Internationale de Gynécologie et d'Obstétrique.
a Adapted from FIGO Committee for Gynecologic Oncology.[3]
II	The cervical carcinoma invades beyond the uterus but has not extended onto the lower third of the vagina or to the pelvic wall.
IIA	Involvement limited to the upper two-thirds of the vagina without parametrial involvement.
–IIA1	–Invasive carcinoma ≤4 cm in greatest dimension.
–IIA2	–Invasive carcinoma >4 cm in greatest dimension.
IIB	With parametrial involvement but not up to the pelvic wall.

Table 3. Definitions of FIGO Stage III^a

Stage	Description	Illustration
FIGO = Fédération Internationale de Gynécologie et d'Obstétrique.
a Adapted from FIGO Committee for Gynecologic Oncology.[3]
b Isolated tumor cells do not change the stage, but their presence should be recorded.
c Adding notation of r (imaging) and p (pathology) to indicate the findings that are used to allocate the case to stage IIIC. For example, if imaging indicates pelvic lymph node metastasis, the stage allocation would be stage IIIC1r; if confirmed by pathological findings, it would be stage IIIC1p. The type of imaging modality or pathology technique used should always be documented. When in doubt, the lower staging should be assigned.
III	The carcinoma involves the lower third of the vagina and/or extends to the pelvic wall and/or causes hydronephrosis or nonfunctioning kidney and/or involves pelvic and/or para-aortic lymph nodes.
IIIA	Carcinoma involves the lower third of the vagina, with no extension to the pelvic wall.
IIIB	Extension to the pelvic wall and/or hydronephrosis or nonfunctioning kidney (unless known to be due to another cause).
IIIC	Involvement of pelvic and/or para-aortic lymph nodes (including micrometastases)b, irrespective of tumor size and extent (with r and p notations).c
–IIIC1	–Pelvic lymph node metastasis only.
–IIIC2	–Para-aortic lymph node metastasis.

Table 4. Definitions of FIGO Stage IV^a

Stage	Description	Illustration
FIGO = Fédération Internationale de Gynécologie et d'Obstétrique.
a Adapted from FIGO Committee for Gynecologic Oncology.[3]
IV	The carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the mucosa of the bladder or rectum. A bullous edema, as such, does not permit a case to be allotted to stage IV.
IVA	Spread of the growth to adjacent pelvic organs.
IVB	Spread to distant organs.

Treatment Option Overview for Cervical Cancer

Patterns-of-care studies clearly demonstrate the negative prognostic effect of increasing tumor volume and spread pattern.[1] Treatment, therefore, may vary within each stage as the individual stages are currently defined by Fédération Internationale de Gynécologie et d'Obstétrique (FIGO).

Chemoradiation Therapy

Five randomized phase III trials have shown an overall survival advantage for cisplatin-based therapy given concurrently with radiation therapy,[2,3,4,5,6] while one trial examining this regimen demonstrated no benefit.[7] The patient populations in these studies included women with FIGO stages IB2 to IVA cervical cancer treated with primary radiation therapy and women with FIGO stages I to IIA disease who were found to have poor prognostic factors (metastatic disease in pelvic lymph nodes, parametrial disease, or positive surgical margins) at the time of primary surgery.

• Although the positive trials vary in terms of the stage of disease, dose of radiation, and schedule of cisplatin and radiation, the trials demonstrate significant survival benefit for this combined approach. The risk of death from cervical cancer was decreased by 30% to 50% with the use of concurrent chemoradiation therapy.
• Based on these results, strong consideration should be given to the incorporation of concurrent cisplatin-based chemotherapy with radiation therapy in women who require radiation therapy for treatment of cervical cancer.[2,3,4,5,6]

Other studies have validated these results.[8,9,10]

Fluorouracil dosing

The DPYD gene encodes an enzyme that catabolizes pyrimidines and fluoropyrimidines, like capecitabine and fluorouracil. An estimated 1% to 2% of the population has germline pathogenic variants in DPYD, which lead to reduced DPD protein function and an accumulation of pyrimidines and fluoropyrimidines in the body.[11,12] Patients with the DPYD*2A variant who receive fluoropyrimidines may experience severe, life-threatening toxicities that are sometimes fatal. Many other DPYD variants have been identified, with a range of clinical effects.[11,12,13] Fluoropyrimidine avoidance or a dose reduction of 50% may be recommended based on the patient's DPYD genotype and number of functioning DPYD alleles.[14,15,16]DPYD genetic testing costs less than $200, but insurance coverage varies due to a lack of national guidelines.[17] In addition, testing may delay therapy by 2 weeks, which would not be advisable in urgent situations. This controversial issue requires further evaluation.[18]

Surgery and Radiation Therapy

Surgery and radiation therapy are equally effective for early stage, small-volume disease.[19] Younger patients may benefit from surgery to preserve the ovaries and avoid vaginal atrophy and stenosis.

Therapy for patients with cancer of the cervical stump is effective and yields results that are comparable with those seen in patients with an intact uterus.[20]

Treatment of In Situ Cervical Cancer

Consensus guidelines have been issued for managing women with cervical intraepithelial neoplasia or adenocarcinoma in situ.[1] Properly treated, tumor control of in situ cervical carcinoma should be nearly 100%. Either expert colposcopic-directed biopsy or cone biopsy is required to exclude invasive disease before therapy is undertaken. A correlation between cytology and colposcopic-directed biopsy is also necessary before local ablative therapy is done. Unrecognized invasive disease treated with inadequate ablative therapy may be the most common cause of failure.[2] Failure to identify the disease, lack of correlation between the Pap smear and colposcopic findings, adenocarcinoma in situ, or extension of disease into the endocervical canal makes a laser, loop, or cold-knife conization mandatory.

The choice of treatment depends on the extent of disease and several patient factors, including age, cell type, desire to preserve fertility, and medical condition.

Treatment Options forIn Situ Cervical Cancer

Treatment options for in situ cervical cancer include the following:

1. Conization.
   • Cold-knife conization (scalpel).
   • Loop electrosurgical excision procedure (LEEP).[3,4]
   • Laser therapy.[5]
2. Hysterectomy for postreproductive patients.
3. Internal radiation therapy for medically inoperable patients.

Hysterectomy is the standard treatment for patients with adenocarcinoma in situ. The disease, which originates in the endocervical canal, may be more difficult to completely excise with a conization procedure. Conization may be offered to select patients with adenocarcinoma in situ who desire future fertility.

Conization

When the endocervical canal is involved, laser or cold-knife conization may be used for selected patients to preserve the uterus, avoid radiation therapy, and more extensive surgery.[6]

In selected cases, the outpatient LEEP may be an acceptable alternative to cold-knife conization. This procedure requires only local anesthesia and obviates the risks associated with general anesthesia for cold-knife conization.[7,8,9] However, controversy exists about the adequacy of LEEP as a replacement for conization; LEEP is unlikely to be sufficient for patients with adenocarcinoma in situ.[10]

Evidence (conization using LEEP):

1. A trial comparing LEEP with cold-knife cone biopsy showed no difference in the likelihood of complete excision of dysplasia.[6]
2. Two case reports suggested that the use of LEEP in patients with occult invasive cancer led to an inability to accurately determine depth of invasion when a focus of the cancer was transected.[11]

Hysterectomy for postreproductive patients

Hysterectomy is standard therapy for women with cervical adenocarcinoma in situ because of the location of the disease in the endocervical canal and the possibility of skip lesions in this region, making margin status a less reliable prognostic factor. However, the effect of hysterectomy compared with conservative surgical measures on mortality has not been studied. Hysterectomy may be performed for squamous cell carcinoma in situ if conization is not possible because of previous surgery, or if positive margins are noted after conization therapy. Hysterectomy is not an acceptable front-line therapy for squamous carcinoma in situ.[12]

Internal radiation therapy for medically inoperable patients

For medically inoperable patients, a single intracavitary insertion with tandem and ovoids for 5,000 mg hours (80 Gy vaginal surface dose) may be used.[13]

Treatment of Stage IA Cervical Cancer

Treatment Options for Stage IA1 Cervical Cancer

Treatment options for stage IA1 cervical cancer include the following:

1. Conization.
2. Total hysterectomy.

Conization

If the depth of invasion is less than 3 mm, no vascular or lymphatic channel invasion is noted, and the margins of the cone are negative, conization alone may be appropriate in patients who wish to preserve fertility.[1]

Total hysterectomy

If the depth of invasion is less than 3 mm, which is proven by cone biopsy with clear margins,[2] no vascular or lymphatic channel invasion is noted, and the frequency of lymph-node involvement is sufficiently low, lymph-node dissection at the time of hysterectomy is not required. Oophorectomy is optional and should be deferred for younger women.

Treatment Options for Stage IA2 Cervical Cancer

Treatment options for stage IA2 cervical cancer include the following:

1. Modified radical hysterectomy with lymphadenectomy.
2. Radical trachelectomy.
3. Intracavitary radiation therapy.

Modified radical hysterectomy with lymphadenectomy

For patients with tumor invasion between 3 mm and 5 mm, modified radical hysterectomy with pelvic-node dissection has been recommended because of a reported risk of lymph-node metastasis of as much as 10%.[2] Radical hysterectomy with node dissection may also be considered for patients for whom the depth of tumor invasion was uncertain because of invasive tumor at the cone margins.

Evidence (open abdominal surgery [open] versus minimally invasive surgery [MIS]):

1. A multicenter, international, randomized trial, the Laparoscopic Approach to Cervical Cancer (LACC [NCT00614211]) trial explored the efficacy of radical hysterectomy and staging via open abdominal surgery versus MIS for patients with early-stage cervical cancer.[3] Patients with stages IA1 (with lymphovascular space invasion), IA2, and IB1 disease and histological subtypes of squamous cell, adenocarcinoma, or adenosquamous carcinoma were eligible for inclusion. The primary end point was noninferiority of MIS compared with open surgery. The metric used was the percent of disease-free patients at 4.5 years postsurgery. The secondary end points were a comparison of the recurrence and survival rates between the two groups.

   Of the planned 740 patients, 632 were accrued when the study was stopped early because of an imbalance in deaths between the two groups. Of 631 eligible patients, 319 were assigned to MIS and 312 to open surgery.

   • The disease-free survival (DFS) rate at 4.5 years was 86% for the MIS group and 96.5% for the open group, a difference of 10.6 percentage points (95% confidence interval [CI], -16.4 to -4.7). At 3 years, the MIS group had a DFS rate of 91.2% versus 97.1% for the open surgery group (hazard ratio [HR] for disease recurrence or death, 3.74; 95% CI, 1.63–8.58).
   • The MIS group also had a lower overall survival (OS) rate at 3 years (OS, 93.8% vs. 99.0% for the open surgery group; HR for death from any cause, 6.0; 95% CI, 1.77–20.30).[3][Level of evidence A1]

   The study concluded that MIS was inferior to an open abdominal approach and should not replace open surgery as the standard for patients with cervical cancer.

2. An epidemiological study used two large U.S. databases, the National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) Database, and confirmed a reduction in OS in patients undergoing MIS radical hysterectomy for stage IA2 and stage IB1 cervical cancer from 2010 to 2013. Additionally, among women who underwent radical hysterectomy in the years 2000 to 2010, there was a decrease in OS after 2006, coincident with the widespread adoption of MIS for cervical cancer.[4][Level of evidence C1]

Although questions remain regarding the use of MIS radical hysterectomy for some subpopulations of good-risk patients, the data from this trial suggest that open abdominal surgery should be considered the standard of care for patients with early-stage cervical cancer who are candidates for radical hysterectomy.

Radical trachelectomy

Patients with stages IA2 to IB disease who desire future fertility may be candidates for radical trachelectomy. In this procedure, the cervix and lateral parametrial tissues are removed, and the uterine body and ovaries are maintained. Most centers use the following criteria for patient selection:

• Desire for future pregnancy.
• Age younger than 40 years.
• Presumed stage IA2 to IB1 disease and a lesion size no greater than 2 cm.
• Preoperative magnetic resonance imaging that shows a margin from the most distal edge of the tumor to the lower uterine segment.
• Squamous, adenosquamous, or adenocarcinoma cell types.

Intraoperatively, the patient is assessed in a manner similar to a radical hysterectomy; the procedure is aborted if more advanced disease than expected is encountered. The margins of the specimen are also assessed at the time of surgery, and a radical hysterectomy is performed if inadequate margins are obtained.[5,6,7,8,9]

Intracavitary radiation therapy

Intracavitary radiation therapy is a treatment option when palliative treatment is appropriate because of other medical conditions and for women who are not surgical candidates.

If the depth of invasion is less than 3 mm, no capillary lymphatic space invasion is noted, and the frequency of lymph-node involvement is sufficiently low, external-beam radiation therapy is not required. One or two insertions with tandem and ovoids for 6,500 mg to 8,000 mg hours (100–125 Gy vaginal surface dose) are recommended.[10]

Treatment of Stages IB and IIA Cervical Cancer

Treatment Options for Stages IB and IIA Cervical Cancer

Treatment options for stage IB and stage IIA cervical cancer include the following:

1. Radiation therapy with concomitant chemotherapy.
2. Radical hysterectomy and bilateral pelvic lymphadenectomy with or without total pelvic radiation therapy plus chemotherapy.
3. Radical trachelectomy.
4. Radiation therapy alone.
5. Immunotherapy.
6. Neoadjuvant chemotherapy (under clinical evaluation).
7. Intensity-modulated radiation therapy (IMRT) (under clinical evaluation).

The size of the tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy.[1]

Either radiation therapy or radical hysterectomy and bilateral lymph–node dissection results in cure rates of 85% to 90% for women with Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) stages IA2 and IB1 small-volume disease. The choice of either treatment depends on patient factors and available local expertise. A randomized trial reported identical 5-year overall survival (OS) and disease-free survival (DFS) rates when comparing radiation therapy with radical hysterectomy.[2]

In stage IB2, for tumors that expand the cervix more than 4 cm, the primary treatment should be concomitant chemotherapy and radiation therapy.[3]

Radiation therapy with concomitant chemotherapy

Concurrent, cisplatin-based chemotherapy with radiation therapy is the standard of care for women who require radiation therapy for treatment of cervical cancer.[4,5,6,7,8,9,10] Radiation therapy protocols for patients with cervical cancer have historically used dosing at two anatomical points, termed point A and point B, to standardize the doses received. Point A is defined as 2 cm from the external os, and 2 cm lateral, relative to the endocervical canal. Point B is also 2 cm from the external os, and 5 cm lateral from the patient midline, relative to the bony pelvis. In general, for smaller tumors, the curative-intent dose for point A is around 70 Gy, whereas for larger tumors, the point A dose may approach 90 Gy.

Evidence (radiation with concomitant chemotherapy):

1. Three randomized phase III trials have shown an OS advantage for cisplatin-based therapy given concurrently with radiation therapy,[4,5,6,7] while one trial that examined this regimen demonstrated no benefit.[8] The patient populations in these studies included women with FIGO stages IB2 to IVA cervical cancer treated with primary radiation therapy, and women with FIGO stages I to IIA disease who, at the time of primary surgery, were found to have poor prognostic factors, including metastatic disease in pelvic lymph nodes, parametrial disease, and positive surgical margins.
   • Although the positive trials vary somewhat in terms of the stage of disease, dose of radiation, and schedule of cisplatin and radiation, the trials demonstrate significant survival benefit for this combined approach.
   • The risk of death from cervical cancer was decreased by 30% to 50% with the use of concurrent chemoradiation therapy.
   • Other trials have confirmed these findings.[9,10]

Brachytherapy

Standard radiation therapy for cervical cancer includes brachytherapy after external-beam radiation therapy (EBRT). Although low-dose rate (LDR) brachytherapy, typically with cesium Cs 137 (137Cs), has been the traditional approach, the use of high-dose rate (HDR) therapy, typically with iridium Ir 192, is rapidly increasing. HDR brachytherapy has the advantages of eliminating radiation exposure to medical personnel, a shorter treatment time, patient convenience, and improved outpatient management. The American Brachytherapy Society has published guidelines for the use of LDR and HDR brachytherapy as components of cervical cancer treatment.[11,12]

Evidence (brachytherapy):

1. In three randomized trials, HDR brachytherapy was comparable with LDR brachytherapy in terms of local-regional control and complication rates.[13,14,15][Level of evidence B1]

   Surgery after radiation therapy may be indicated for some patients with tumors confined to the cervix that respond incompletely to radiation therapy or for patients whose vaginal anatomy precludes optimal brachytherapy.[16]

Pelvic node disease

The resection of macroscopically involved pelvic nodes may improve rates of local control with postoperative radiation therapy.[17] Patients who underwent extraperitoneal lymph–node sampling had fewer bowel complications than those who had transperitoneal lymph–node sampling.[18,19,20] Patients with close vaginal margins (<0.5 cm) may also benefit from pelvic radiation therapy.[21]

Radical hysterectomy and bilateral pelvic lymphadenectomy with or without total pelvic radiation therapy plus chemotherapy

Radical hysterectomy and bilateral pelvic lymphadenectomy may be considered for women with stages IB to IIA disease.

Evidence (radical hysterectomy and bilateral pelvic lymphadenectomy with or without total pelvic radiation therapy plus chemotherapy):

1. An Italian group randomly assigned 343 women with stage IB and IIA cervical cancer to surgery or radiation therapy. The radiation therapy included EBRT and one 137Cs LDR insertion, with a total dose to point A from 70 to 90 Gy (median 76 Gy). Patients in the surgery arm underwent a class III radical hysterectomy, pelvic lymphadenectomy, and selective, para-aortic lymph–node dissection. Adjuvant radiation therapy was given to patients with high-risk pathological features in the uterine specimen or positive lymph nodes. Adjuvant radiation therapy was EBRT to a total dose of 50.4 Gy over 5 to 6 weeks.[2][Level of evidence A1]
   • The primary outcome was OS at 5 years, with secondary measures of rate of recurrence and complications. With a median follow-up of 87 months, the OS rate was the same in both groups at 83% (hazard ratio [HR], 1.2; 95% confidence interval [CI], 0.7–2.3; P = .8).
   • Complications were highest among the patients who received adjuvant radiation after surgery.
   • In general, radical hysterectomy should be avoided in patients who are likely to require adjuvant therapy.

Evidence (open abdominal surgery [open] versus minimally invasive surgery [MIS]):

1. A multicenter, international, randomized trial, the Laparoscopic Approach to Cervical Cancer (LACC [NCT00614211]) trial, explored the efficacy of radical hysterectomy and staging via open abdominal surgery (open) versus MIS for patients with early-stage cervical cancer.[22] Patients with stages IA1 (with lymphovascular space invasion), IA2, and IB1 disease and histological subtypes of squamous cell, adenocarcinoma or adenosquamous carcinoma were eligible for inclusion. The primary end point was noninferiority of MIS compared with open surgery; the metric used was the percent of disease-free patients at 4.5 years postsurgery. The secondary end points were a comparison of the recurrence and survival rates between the two groups.

   Of the planned 740 patients, 632 were accrued when the study was stopped early because of an imbalance in deaths between the two groups. Of 631 eligible patients, 319 were assigned to MIS and 312 to open surgery.

   • The DFS rate at 4.5 years was 86% for the MIS group and 96.5% for the open group, a difference of 10.6 percentage points (95% CI, -16.4 to -4.7). At 3 years, the MIS group had a DFS rate of 91.2% versus 97.1% for the open surgery group (HR for disease recurrence or death, 3.74; 95% CI, 1.63–8.58).
   • The MIS group also had a lower OS rate at 3 years (OS, 93.8% vs. 99.0% for the open surgery group; HR for death from any cause, 6.0; 95% CI, 1.77– 20.30).[22][Level of evidence A1]

   The study concluded that MIS was inferior to an open abdominal approach and should not replace open surgery as the standard for cervical cancer patients.

2. An epidemiological study using two large U.S. databases (National Cancer Database [NCDB] and Surveillance, Epidemiology, and End Results [SEER] Program database) confirmed a reduction in OS in patients undergoing MIS radical hysterectomy for stage IA2 and stage IB1 cervical cancer from 2010 to 2013. Additionally, among women who underwent radical hysterectomy in the years 2000 to 2010, there was a decrease in OS after 2006, coincident with the widespread adoption of MIS for cervical cancer.[23][Level of evidence C1]

Although questions remain regarding the use of MIS radical hysterectomy for some subpopulations of good-risk patients, the data from this trial suggest that open abdominal surgery should be considered the standard of care for patients with early-stage cervical cancer who are candidates for radical hysterectomy.

Adjuvant radiation therapy postsurgery

Based on recurrence rates in clinical trials, two classes of recurrence risk have been defined. Patients with a combination of large tumor size, lymph vascular space invasion, and deep stromal invasion in the hysterectomy specimen are deemed to have intermediate-risk disease. These patients are candidates for adjuvant EBRT.[24] Patients whose pathology shows positive margins, positive parametria, or positive lymph nodes are high-risk candidates for recurrence.

Evidence (adjuvant radiation therapy postsurgery):

1. The Gynecologic Oncology Group (GOG) compared adjuvant radiation therapy alone with radiation therapy plus cisplatin plus fluorouracil (5-FU) after radical hysterectomy for patients in the high-risk group. Postoperative patients were eligible if their pathology showed any one of the following: positive parametria, positive margins, or positive lymph nodes. Patients in both arms received 49 Gy to the pelvis. Patients in the experimental arm also received cisplatin (70 mg/m²) and a 96-hour infusion of 5-FU (1,000 mg/m² /d every 3 weeks for four cycles); the first two cycles were concurrent with the radiation therapy.[6][Level of evidence A1]
   • There were 268 patients evaluated with a primary end point of OS. The study results were reported early because of the positive results in other trials of concomitant cisplatin and radiation therapy.
   • The estimated 4-year survival rate was 81% for chemotherapy plus radiation therapy and 71% for radiation therapy alone (HR, 1.96; P = .007).
   • As expected, grade 4 toxicity was more common in the chemotherapy plus radiation therapy group, with hematologic toxicity predominating.

Radical surgery has been performed for small lesions, but the high incidence of pathological factors leading to postoperative radiation with or without chemotherapy make primary concomitant chemotherapy and radiation a more common approach in patients with larger tumors. Radiation in the range of 50 Gy administered for 5 weeks plus chemotherapy with cisplatin with or without 5-FU should be considered in patients with a high risk of recurrence.

Para-aortic nodal disease

After surgical staging, patients found to have small-volume para-aortic nodal disease and controllable pelvic disease may be cured with pelvic and para-aortic radiation therapy.[25] Treatment of patients with unresected para-aortic nodes with extended-field radiation therapy and chemotherapy leads to long-term disease control in patients with low-volume (<2 cm) nodal disease below L3.[18] A single study (RTOG-7920) showed a survival advantage in patients with tumors larger than 4 cm who received radiation therapy to para-aortic nodes without histological evidence of disease.[26] Toxic effects were greater with para-aortic radiation therapy than with pelvic radiation therapy alone but were mostly confined to patients with previous abdominopelvic surgery.[26] The use of intensity-modulated radiation therapy (IMRT) may minimize the effects to the small bowel usually associated with this treatment.[27]

Radical trachelectomy

Patients with presumed early-stage disease who desire future fertility may be candidates for radical trachelectomy. In this procedure, the cervix and lateral parametrial tissues are removed, and the uterine body and ovaries are maintained. The patient selection differs somewhat between groups; however, general criteria include the following:

• Desire for future pregnancy.
• Age younger than 40 years.
• Presumed stage IA2 to IB1 disease and a lesion size no greater than 2 cm.
• Preoperative magnetic resonance imaging that shows a margin from the most distal edge of the tumor to the lower uterine segment.
• Squamous, adenosquamous, or adenocarcinoma cell types.

Intraoperatively, the patient is assessed in a manner similar to a radical hysterectomy; the procedure is aborted if more advanced disease than expected is encountered. The margins of the specimen are also assessed at the time of surgery, and a radical hysterectomy is performed if inadequate margins are obtained.[28,29,30,31,32]

Radiation therapy alone

External-beam pelvic radiation therapy combined with two or more intracavitary brachytherapy applications is appropriate therapy for patients with stage IA2 and IB1 lesions. For patients with stage IB2 and larger lesions, radiosensitizing chemotherapy is indicated. The role of radiosensitizing chemotherapy in patients with stage IA2 and IB1 lesions is untested. However, it may prove beneficial in certain cases.

Immunotherapy

Evidence (immunotherapy):

1. KEYNOTE-A18 (NCT04221945) was a multicenter, phase III, randomized trial that included 1,060 women with newly diagnosed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the cervix. Patients had stage IB2 or IIB node-positive disease or stage III to IVA disease and had received no prior treatment. Patients were randomly assigned to receive either chemoradiation therapy (with cisplatin) plus pembrolizumab (every 3 weeks for five cycles) or chemoradiation therapy plus placebo. All patients received maintenance therapy with pembrolizumab or placebo every 6 weeks for 15 cycles. All patients received brachytherapy, and 94% of patients had programmed death-ligand 1 (PD-L1)–positive disease. The dual primary end points were progression-free survival (PFS) and OS. The median follow-up time was 17.9 months.[33]
   • The 24-month OS rate was 87% in the pembrolizumab group and 81% in the placebo group (HR, 0.73; 95% CI, 0.49–1.07).[33][Level of evidence B1]
   • There was a statistically significant improvement in PFS (HR, 0.70; 95% CI, 0.55–0.89). The 24-month PFS rate was 68% in the pembrolizumab group and 57% in the placebo group.
   • Patients with stage III or IV disease had a greater improvement in PFS (HR, 0.58; 95% CI, 0.42–0.80).

Neoadjuvant chemotherapy

Several groups have investigated the role of neoadjuvant chemotherapy to convert patients who are conventional candidates for chemoradiation into candidates for radical surgery.[34,35,36,37,38] Multiple regimens have been used; however, almost all use a platinum backbone. The largest randomized trial to date was reported in 2001, and its accrual was completed before the standard of care included the addition of cisplatin to radiation therapy.[39] As a result, the control arm received radiation therapy alone. Although there was an improvement in OS for the experimental arm, the results do not reflect current practice. This study accrued patients with stages IB through IVA disease, but improvement in the experimental arm was only noted for participants with early-stage disease (stages IB, IIA, or IIB).

EORTC-55994 (NCT00039338) randomly assigned patients with stages IB2, IIA2, and IIB cervical cancer to standard chemoradiation or neoadjuvant chemotherapy (with a cisplatin backbone for three cycles) followed by evaluation for surgery. With OS as the primary end point, this trial may delineate whether there is a role for neoadjuvant chemotherapy for this patient population.

IMRT

IMRT is a radiation therapy technique that allows for conformal dosing of target anatomy while sparing neighboring tissue. Theoretically, this technique should decrease radiation therapy–related toxicity, but this could come at the cost of decreased efficacy if tissue is inappropriately excluded from the treatment field. Several institutions have reported their experience with IMRT for postoperative adjuvant therapy in patients with intermediate-risk and high-risk disease after radical surgery.[40,41,42] A Radiation Therapy Oncology Group (RTOG) phase II trial (RTOG-0418 [NCT00331760]) evaluated the use of IMRT in patients with both cervical and endometrial cancers who require adjuvant radiation therapy.

Treatment of Stages IIB, III, and IVA Cervical Cancer

Treatment Options for Stages IIB, III, and IVA Cervical Cancer

The size of the primary tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy.[1] Survival and local control are better with unilateral rather than bilateral parametrial involvement.[2] Patterns-of-care studies in stages IIIA and IIIB patients indicate that survival is dependent on the extent of the disease, with unilateral pelvic wall involvement predicting a better outcome than bilateral involvement, which in turn predicts a better outcome than involvement of the lower third of the vaginal wall.[2] These studies also reveal a progressive increase in local control and survival paralleling a progressive increase in paracentral (point A) dose and use of intracavitary treatment. The highest rate of central control was seen with paracentral (point A) doses of more than 85 Gy.[3]

Treatment options for stage IIB, stage III, and stage IVA cervical cancer include the following:

1. Radiation therapy with concomitant chemotherapy. [4]
2. Interstitial brachytherapy.
3. Neoadjuvant chemotherapy.
4. Immunotherapy.

Radiation therapy with concomitant chemotherapy

Strong consideration should be given to the use of intracavitary radiation therapy and external-beam radiation therapy (EBRT) to the pelvis combined with cisplatin or cisplatin/fluorouracil (5-FU).[5,6,7,8,9,10,11,12]

Evidence (radiation therapy with concomitant chemotherapy):

1. Five randomized phase III trials have shown an overall survival (OS) advantage for cisplatin-based therapy given concurrently with radiation therapy,[5,6,7,8,9,10] but one trial that examined this regimen demonstrated no benefit.[13] The patient populations in these studies included women with Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) stages IB2 to IVA cervical cancer treated with primary radiation therapy, and women with FIGO stages I to IIA disease who, at the time of primary surgery, were found to have poor prognostic factors, including metastatic disease in pelvic lymph nodes, parametrial disease, and positive surgical margins.
   • Although the positive trials vary somewhat in terms of the stage of disease, dose of radiation, and schedule of cisplatin and radiation, the trials demonstrate significant survival benefit for this combined approach.
   • The risk of death from cervical cancer was decreased by 30% to 50% with the use of concurrent chemoradiation therapy.

Evidence (low-dose rate vs. high-dose rate intracavitary radiation therapy):

1. Although low-dose rate (LDR) brachytherapy, typically with cesium Cs 137, has been the traditional approach, the use of high-dose rate (HDR) therapy, typically with iridium Ir 192, is rapidly increasing. HDR brachytherapy provides the advantage of eliminating radiation exposure to medical personnel, a shorter treatment time, patient convenience, and improved outpatient management. The American Brachytherapy Society has published guidelines for the use of LDR and HDR brachytherapy as a component of cervical cancer treatment.[14,15]
2. In three randomized trials, HDR brachytherapy was comparable with LDR brachytherapy in terms of local-regional control and complication rates.[16,17,18][Level of evidence B1]
3. In an attempt to improve upon standard chemoradiation, a phase III randomized trial compared concurrent gemcitabine plus cisplatin and radiation therapy followed by adjuvant gemcitabine and cisplatin (experimental arm) with concurrent cisplatin plus radiation (standard chemoradiation) in patients with stages IIB to IVA cervical cancer.[19][Level of evidence A1] A total of 515 patients from nine countries were enrolled. The schedule for the experimental arm was cisplatin (40 mg/m²) and gemcitabine (125 mg/m²) weekly for 6 weeks, with concurrent EBRT (50.4 Gy in 28 fractions) followed by brachytherapy (30–35 Gy in 96 hours) and then two adjuvant 21-day cycles of cisplatin (50 mg/m²) on day 1 plus gemcitabine (1,000 mg/m²) on days 1 and 8. The standard arm was cisplatin (40 mg/m²) weekly for 6 weeks with concurrent EBRT and brachytherapy as described for the experimental arm.
   • The primary end point was progression-free survival (PFS) at 3 years; however, the study found improvement in the experimental arm for PFS at 3 years (74.4%; 95% confidence interval [CI], 68%–79.8% vs. 65.0%; 95% CI, 58.5%–70.7%); overall PFS (hazard ratio [HR], 0.68; 95% CI, 0.49–0.95); and OS (HR, 0.68; 95% CI, 0.49–0.95). Patients in the experimental arm had increased hematologic and nonhematologic grade 3 or 4 toxic effects, and two deaths in the experimental arm were possibly related to treatment.

   A subgroup analysis showed an increased benefit in patients with a higher stage of disease (stages III–IVA vs. stage IIB), which suggested that the increased toxic effects of the experimental protocol may be justified for these patients.[20] Additional investigation is needed to determine which aspect of the experimental arm led to improved survival (i.e., the addition of the weekly gemcitabine, the adjuvant chemotherapy, or both) and to determine quality of life during and after treatment, a condition that was omitted from the protocol.

Interstitial brachytherapy

For patients who complete EBRT and have bulky cervical disease such that standard brachytherapy cannot be placed anatomically, interstitial brachytherapy has been used to deliver adequate tumoricidal doses with an acceptable toxicity profile.[21]

Neoadjuvant chemotherapy

Several groups have investigated the role of neoadjuvant chemotherapy to convert patients who are conventional candidates for chemoradiation into candidates for radical surgery.[22,23,24,25,26] Multiple regimens have been used; however, almost all use a platinum backbone. The largest randomized trial to date was reported in 2001, and its accrual was completed before the standard of care included the addition of cisplatin to radiation therapy.[27] As a result, although there was an improvement in OS for the experimental arm, the results are not reflective of current practice. This study accrued patients with stages IB through IVA disease, but improvement in the experimental arm was only noted for participants with early-stage disease (stages IB, IIA, or IIB).

EORTC-55994 (NCT00039338) randomly assigned patients with stages IB2, IIA2, and IIB cervical cancer to standard chemoradiation or neoadjuvant chemotherapy (with a cisplatin backbone for three cycles) followed by evaluation for surgery. With OS as the primary end point, this trial may delineate whether there is a role for neoadjuvant chemotherapy for this patient population.

Immunotherapy

Evidence (immunotherapy):

1. KEYNOTE-A18 (NCT04221945) was a multicenter, phase III, randomized trial that included 1,060 women with newly diagnosed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the cervix. Patients had stage IB2 or IIB node-positive disease or stage III to IVA disease and had received no prior treatment. Patients were randomly assigned to receive either chemoradiation therapy (with cisplatin) plus pembrolizumab (every 3 weeks for five cycles) or chemoradiation therapy plus placebo. All patients received maintenance therapy with pembrolizumab or placebo every 6 weeks for 15 cycles. All patients received brachytherapy, and 94% of patients had programmed death-ligand 1 (PD-L1)–positive disease. The dual primary end points were PFS and OS. The median follow-up time was 17.9 months.[28]
   • The 24-month OS rate was 87% in the pembrolizumab group and 81% in the placebo group (HR, 0.73; 95% CI, 0.49–1.07).[28][Level of evidence B1]
   • There was a statistically significant improvement in PFS (HR, 0.70; 95% CI, 0.55–0.89). The 24-month PFS rate was 68% in the pembrolizumab group and 57% in the placebo group.
   • Patients with stage III or IV disease had a greater improvement in PFS (HR, 0.58; 95% CI, 0.42–0.80).

Lymph Node Management

Patients who are surgically staged as part of a clinical trial and are found to have small-volume para-aortic nodal disease and controllable pelvic disease may be cured with pelvic and para-aortic radiation therapy.[29] Treatment of patients with unresected periaortic nodes with extended-field radiation therapy leads to long-term disease control in patients with low-volume (<2 cm) nodal disease below L3.[30] A single study (RTOG-7920) showed a survival advantage in patients who received radiation therapy to para-aortic nodes without histological evidence of disease.[31] Toxic effects are greater with para-aortic radiation than with pelvic radiation alone but were mostly confined to patients with previous abdominopelvic surgery.[31]

If postoperative EBRT is planned following surgery, extraperitoneal lymph–node sampling is associated with fewer radiation-induced complications than a transperitoneal approach.[32] Patients who underwent extraperitoneal lymph–node sampling had fewer bowel complications than those who had transperitoneal lymph–node sampling.[30,32,33]

The resection of macroscopically involved pelvic nodes may improve rates of local control with postoperative radiation therapy.[34] In addition, prospective data points to improvement in outcomes for patients who undergo resection of positive para-aortic lymph nodes before curative intent chemoradiation therapy; however, only patients with minimal nodal involvement (<5 mm) benefited.[35]

Treatment of Stage IVB and Recurrent Cervical Cancer

Treatment Options for Stage IVB and Recurrent Cervical Cancer

With the exception of immunotherapy, which has provided prolonged disease-free survival, other options are unlikely to result in curative outcomes and are mostly applied for palliative purposes.

Treatment options for stage IVB and recurrent cervical cancer include the following:

1. Immunotherapy.
2. Radiation therapy and chemotherapy.
3. Palliative chemotherapy and other systemic therapy.
4. Pelvic exenteration.
5. Phase I and phase II clinical trials of new anticancer drugs.

Immunotherapy

Based on the results of the phase II KEYNOTE-158 trial (NCT02628067), the U.S. Food and Drug Administration (FDA) approved the anti–programmed cell death-1 (PD-1) immune checkpoint inhibitor, pembrolizumab, for women with recurrent or metastatic cervical cancer whose tumors express programmed death-ligand 1 (PD-L1) (combined positive score [CPS], ≥1). Additional data on the benefits of pembrolizumab have been gathered from several trials.

Evidence (immunotherapy):

1. The international multicenter BEATcc trial (NCT03556839) included 410 women with stage IVB, persistent, or recurrent squamous cell or adenocarcinoma of the cervix not amenable to curative surgery or radiation therapy. Patients had not received previous systemic therapy. Patients were randomly assigned to receive either bevacizumab plus chemotherapy (carboplatin or cisplatin with paclitaxel) (the control arm) or the experimental arm, which added atezolizumab to the control regimen. The dual primary end points were progression-free survival (PFS) and overall survival (OS), and the trial was biomarker unselective for PD-L1 expression.[1]
   • After a median follow-up of 32.9 months, the median PFS was 10.4 months for patients in the control arm and 13.7 months for patients in the experimental arm (hazard ratio [HR], 0.62; 95% confidence interval [CI], 0.48–0.78; P < .0001). The median OS was 22.8 months for patients in the control arm and 32.1 months for patients in the experimental arm (HR, 0.68; 95% CI, 0.52–0.88; P = .0046).[1][Level of evidence A1]
2. KEYNOTE-826 (NCT03635567) was a multicenter, phase III, randomized trial that included 617 women with persistent, recurrent, or metastatic adenosquamous or squamous cell carcinoma of the cervix not amenable to curative treatment. Patients had measurable disease. All patients were treated with cisplatin or carboplatin combined with paclitaxel, with the option to add bevacizumab at the treating physician's discretion. Patients received six cycles and were randomly assigned 1:1 to receive pembrolizumab or placebo every 3 weeks for up to 35 cycles. The median follow-up was 39.1 months, with dual primary end points of PFS and OS. Approximately 89% of women had a PD-L1 CPS score of 1 or higher.[2]
   • The median OS was 26.4 months for patients who received pembrolizumab and 16.8 months for patients who received placebo (HR, 0.63; 95% CI, 0.52–0.77). This benefit was not maintained in women with a CPS score less than 1. The benefit was maintained in the group of women who did not receive bevacizumab.[2][Level of evidence A1]
   • The median PFS was 10.4 months for patients who received pembrolizumab and 8.2 months for patients who received placebo (HR, 0.61; 95% CI, 0.50–0.74).
3. KEYNOTE-A18 (NCT04221945) was a multicenter, phase III, randomized trial that included 1,060 women with newly diagnosed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the cervix. Patients had stage IB2 or IIB node-positive disease or stage III to IVA disease and had received no prior treatment. Patients were randomly assigned to receive either chemoradiation therapy (with cisplatin) plus pembrolizumab (every 3 weeks for five cycles) or chemoradiation therapy plus placebo. All patients received maintenance therapy with pembrolizumab or placebo every 6 weeks for 15 cycles. All patients received brachytherapy, and 94% of patients had PD-L1–positive disease. The dual primary end points were PFS and OS. The median follow-up time was 17.9 months.[3]
   • The 24-month OS rate was 87% in the pembrolizumab group and 81% in the placebo group (HR, 0.73; 95% CI, 0.49–1.07).[3][Level of evidence B1]
   • There was a statistically significant improvement in PFS (HR, 0.70; 95% CI, 0.55–0.89). The 24-month PFS rate was 68% in the pembrolizumab group and 57% in the placebo group.
   • Patients with stage III or IV disease had a greater improvement in PFS (HR, 0.58; 95% CI, 0.42–0.80).
4. KEYNOTE-158 (NCT02628067) was a multicenter nonrandomized trial that included 98 patients with recurrent or metastatic cervical cancer. Patients received 200 mg of pembrolizumab every 3 weeks intravenously until unacceptable toxicity or disease progression.[4] A separate analysis was performed in 77 patients whose tumors expressed PD-L1 (CPS ≥1); 92% had squamous histology.
   • The overall response rate among PD-L1–positive patients was 16% (95% CI, 8.8%–25.9%) with 3 complete responses and 10 partial responses; 17 patients were stable.
   • The median PFS was 2.1 months, and OS was 9.4 months in these marker-positive patients.
   • Treatment-related adverse events were noted in 65% of patients. The most common were hypothyroidism (10.2%), decreased appetite (9.2%), fatigue (9.2%), and diarrhea (8.2%).[4][Level of evidence B4]
5. GOG-0240 (NCT00803062), which enrolled patients with metastatic, persistent, or recurrent cervical carcinoma, was designed to answer the following two questions:[5]
   • Can a nonplatinum combination show improvement over the standard of cisplatin-paclitaxel in this population, which was previously treated with cisplatin during radiation therapy?
   • Can the addition of bevacizumab improve combination chemotherapy in patients with stage IVB, persistent, or recurrent cervical cancer?

   Patients were randomly assigned to one of the following four treatment arms:

   • Cisplatin (50 mg/m²) + paclitaxel (135 mg/m² or 175 mg/m²) on day 1 (PC).
   • PC + bevacizumab (15mg/kg) on day 1.
   • Topotecan (0.75 mg/m²) on days 1–3 + paclitaxel (175 mg/m²) on day 1 (PT).
   • PT + bevacizumab (15mg/kg) on day 1.

   Additional study methods and results included the following:

   • The primary end point was OS, and 452 patients were evaluable.
   • The combination PT was not superior to PC and had a HR_death of 1.2 (99% CI, 0.82–1.76). Previous exposure to platinum did not affect this result.
   • The addition of bevacizumab to combination chemotherapy led to: (1) improved OS: 17 months for chemotherapy plus bevacizumab versus 13.3 months for chemotherapy alone (HR, 0.71; 98% CI, 0.54–0.95) and (2) extended PFS: 8.2 months for chemotherapy plus bevacizumab versus 5.9 months for chemotherapy alone (HR, 0.67; 95% CI, 0.54–0.82).
   • The addition of bevacizumab was well tolerated and showed no difference in quality of life between the two groups.
   • Patients who received bevacizumab were more likely to have grade 3 or higher fistulae (6% vs. 0%), and grade 3 or higher thromboembolic events (8% vs. 1%) compared with patients who received chemotherapy alone.
   • As a result, the addition of bevacizumab may be considered for this patient population.

Radiation therapy and chemotherapy

Radiation therapy and chemotherapy (fluorouracil with or without mitomycin) may cure 40% to 50% of patients with recurrence in the pelvis after initial radical surgery.[6]

Palliative chemotherapy and other systemic therapy

Chemotherapy can be used for palliation. Drugs used for palliative chemotherapy are shown in Table 6.

Cisplatin in combination with other drugs

Since the drug was initially introduced in the 1970s, the regimen used most often to treat recurrent cervical cancer has been single-agent cisplatin given intravenously at 50 mg/m² every 3 weeks.[7] The Gynecologic Oncology Group (GOG) reported on sequential randomized trials of combination chemotherapy for stage IVB, recurrent, or persistent cervical cancer.[14,17,19,20,21,22]

Evidence (cisplatin in combination with other drugs):

1. GOG-110, GOG-0179, GOG-0169 (NCT00803062)
   • GOG-110: The ifosfamide + cisplatin combination was superior to cisplatin alone in the secondary end point of response rates, but at the cost of increased toxicity.
   • GOG-0179: The cisplatin + topotecan (CT) doublet combination had a significant advantage in OS compared with cisplatin alone, leading to approval of this indication for topotecan by the FDA. However, cisplatin alone underperformed in this trial because as many as 40% of the patients had already received cisplatin up front as a radiosensitizer.[17]
   • GOG-0169: The paclitaxel + cisplatin (PC) combination, similarly, was superior in response rates and PFS, and its toxicity was similar to that of the single agent except in patients with GOG performance status 2 (scale: 0, asymptomatic–4, totally bedridden). Therefore, PC was chosen as the reference arm in GOG-0204 (NCT00064077).
2. GOG-0204 enrolled 513 patients and compared four cisplatin-based doublet regimens. The trial was closed early because no one experimental arm was likely to significantly lower the HR_death relative to PC:[22]
   • 1.15 (95% CI, 0.79–1.67) for vinorelbine + cisplatin (VC).
   • 1.32 (95% CI, 0.91–1.92) for gemcitabine plus cisplatin.
   • 1.27 (95% CI, 0.90–1.78) for CT. Trends in response rate, PFS, and OS favored CT.
   • Patients in the four study arms experienced different grades of neutropenia, infection, and alopecia.[22] There were no differences in health-related quality of life during treatment.[23] However, patients who received PC had more neurological side effects.

Pelvic exenteration

No standard treatment is available for patients with recurrent cervical cancer that has spread beyond the confines of a radiation or surgical field. For locally recurrent disease, pelvic exenteration can lead to 5-year survival rates of 32% to 62% in selected patients.[24,25] These patients are appropriate candidates for clinical trials testing drug combinations or new anticancer agents.

Cervical Cancer During Pregnancy

During pregnancy, no therapy is warranted for preinvasive lesions of the cervix, including carcinoma in situ, although expert colposcopy is recommended to exclude invasive cancer.

Diagnosis

Treatment of cervical cancer in pregnancy is predicated on the extent of disease and the gestational age at diagnosis. Patients should undergo biopsy as needed and imaging to establish the extent of disease to make the most informed choices. The most appropriate imaging modality in pregnancy is magnetic resonance imaging, when indicated.

Treatment of Stage I Disease

Pregnancy does not alter the course of cervical cancer. As a result, in certain cases, patients may elect to postpone treatment until its effects on the pregnancy are minimized. This may be considered for patients with the more common and less aggressive histological subtypes: squamous, adenocarcinoma, and adenosquamous. Patients with high-risk subtypes, such as small cell or neuroendocrine tumors, should be counseled toward immediate treatment despite the effects on the fetus, given their risk of progression.

Patients with early stage (IA) disease may safely undergo fertility-sparing treatments, including cervical conization or radical trachelectomy, as indicated. The optimal timing for this procedure is in the second trimester, before fetal viability. Some authors have suggested waiting until the completion of a pregnancy to initiate treatment.[1] For patients with IA2 and IB disease, such a delay may also be safe, but because of a risk of lymphatic spread, assessment of lymph-node status should first be ascertained. The status is best determined surgically via a laparoscopic or open lymph-node dissection, which can be safely performed up to approximately 20 weeks of pregnancy.[2,3] In patients without lymphatic spread, waiting for fetal viability to initiate treatment is an option. Patients with positive lymph nodes should be counseled toward immediate treatment.

Treatment of Stages II, III, and IV Disease

For patients with stage II or greater disease, waiting for fetal viability is generally not acceptable.[4] The standard of care is curative intent chemotherapy and radiation therapy. This treatment is toxic to the fetus and, without ovarian transposition, will render the ovaries nonfunctional after treatment. Evacuation of the fetus should be performed before radiation is initiated. When this is not possible, the radiation will generally cause a spontaneous abortion 3 to 5 weeks after initiating treatment.

Neoadjuvant Chemotherapy

Neoadjuvant chemotherapy has been offered to patients with locally advanced disease as a way to initiate treatment while maintaining the pregnancy.[1] Most chemotherapy agents can be initiated safely in the second trimester of pregnancy and beyond; mild growth restriction of the fetus is the most common side effect. Restriction of growth has been reported in a relatively small number of patients, and data are lacking on long-term outcomes for these women. As a result, this strategy should be considered with caution. Most of the patients in the reports underwent standard treatment (either surgery or radiation therapy) after completion of the pregnancy.
