Efficacy of cisplatin and cyclophosphamide combination for recurrent and metastatic carcinoma of the uterine cervix.
The efficacy of a combination of cyclophosphamide and cisplatin in patients with metastatic and recurrent carcinoma of the cervix, was tested. Thirty patients were included in the study. Initially, 27 patients (90%) had received pelvic radiation and intracavitary boost and one patient was additionally given paraaortic radiation. Cisplatin was given at 75 mg/m2 followed by cyclophosphamide at 750 mg/m2 on day 1 with three weekly intervals for a maximum of six cycles. All patients received a median of four cycles of chemotherapy. The overall response rate for all eligible patients was 20% (continuous CR: 1, CR: 1, PR: 4 patients). Overall response rate and progressive response in patients with relapse within the previous radiation field were 9.5% and 66.7%, respectively; while for patients who had recurrent disease outside any irradiated area both were 44.4%. Eighteen patients (60%) had early withdrawal from the planned schedule, which was due to patient incompliance in seven patients (23.3%), disease progression in ten (33.3%) and early death after the first cycle in one patient (3.3%). Anemia was the most frequent toxicity, necessiating 24 transfusions in nine patients (30%). WHO grade 3 and 4 toxicity were anemia: 13 (43.3%), leucopenia: one (3.3%), thrombocytopenia: two (6.6%), renal: one, emesis: nine (30.0%) patients. The median survival duration for all eligible patients was 11 months. Univariate analysis revealed that progressive response to chemotherapy was the only prognostic factor for survival (7.1 vs 16.8 months, p = 0.003). The combination of cisplatin and cyclophosphamide did not appear to be more active than single agent cisplatin in this patient group with a relatively poor prognosis. Further studies are required to determine a better therapeutic approach for patients with relapsed carcinoma of the cervix.
