Recurrent Cervical Cancer Treatment
Treatment Options for Recurrent Cervical Cancer
Treatment options for recurrent cervical cancer include the following:
Radiation therapy and chemotherapy
For recurrence in the pelvis after initial radical surgery, radiation therapy and chemotherapy (fluorouracil with or without mitomycin) may cure 40% to 50% of patients.
Chemotherapy can be used for palliation. Drugs used for palliative chemotherapy are shown in Table 7.
|Drug name||Response rate|
|Irinotecan ||21% in patients previously treated with chemotherapy|
|Bevacizumab ||11%; 24% survived progression free for at least 6 months, as seen in GOG-0227C (NCT00025233)|
Cisplatin in combination with other drugs
Single-agent cisplatin administered intravenously at 50 mg/m² every 3 weeks has been the regimen most often used to treat recurrent cervical cancer since the drug was initially introduced in the 1970's. More recently, the GOG has reported on sequential randomized trials dealing with combination chemotherapy for stage IVB, recurrent, or persistent cervical cancer.[9,12,14-17]
Evidence (cisplatin in combination with other drugs):
- GOG-110, GOG-0179, GOG-0169 (NCT00803062)
- GOG 110: The ifosfamide + cisplatin combination was superior to cisplatin alone in the secondary endpoint of response rates, but at the cost of increased toxicity.
- GOG 0179: The cisplatin + topotecan (CT) doublet combination had a significant advantage in overall survival (OS) compared with cisplatin alone, leading to approval of this indication for topotecan by the U.S. Food and Drug Administration. However, cisplatin alone underperformed in this trial because as many as 40% of the patients had already received cisplatin up front as a radiosensitizer.
- GOG 0169: The paclitaxel + cisplatin (PC) combination, similarly, was superior in response rates and progression-free survival (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, paclitaxel plus cisplatin (PC) was chosen as the reference arm in GOG-0204 (NCT00064077).
- 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 hazard ratio of death relative to PC:
- 1.15 (95% confidence interval [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. Trend in RR, PFS, and OS favored CT.
- The patients in the various arms of the study differed in the extent of neutropenia, infection, and alopecia that they experienced, but none of the patients in the study arms differed in health-related quality of life during treatment. However, there were more neurologic side effects for PC.
- GOG-0240 (NCT00803062) was designed to answer the following two questions:
- Can a nonplatinum combination show improvement over the standard of cisplatin-paclitaxel in this population previously treated with cisplatin during radiation therapy?
- Can the addition of bevacizumab improve upon combination chemotherapy in patients with stage IVB, persistent or recurrent cervical cancer?
Patients were randomly assigned to 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) d1–d3 + 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 endpoint was OS, and 452 patients were evaluable.
- The combination PT was not superior to PC and had a hazard ratio (HR) for 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 an improvement in OS: 17 months for chemotherapy plus bevacizumab versus 13.3 months for chemotherapy alone (HR, 0.71; 98% CI, 0.54–0.95), and extended PFS: 8.2 months for chemotherapy plus bevacizumab versus 5.9 months for chemotherapy alone, HR, 0.67; (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 on 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 on chemotherapy alone.
- As a result, the addition of bevacizumab may be considered for this patient population.
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 a 5-year survival rate of 32% to 62% in selected patients.[20,21] These patients are appropriate candidates for clinical trials testing drug combinations or new anticancer agents.
Treatment Options Under Clinical Evaluation for Recurrent Cervical Cancer
Treatment options under clinical evaluation for recurrent cervical cancer include the following:
- New anticancer drugs in phase I and phase II clinical trials.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent cervical cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
