BACKGROUND: The efficacy and toxicity of combined therapy with irinotecan (CPT-11) and mitomycin-C (MMC) in a neoadjuvant setting were evaluated in patients with locally advanced squamous cell carcinoma (SCC) of the uterine cervix. PATIENTS AND METHODS: Eligibility included patients with previously untreated cervical carcinoma. CPT-11 (100 mg/m2) was administered on days 1, 8 and 15 intravenously (i.v.), while MMC (10 mg/m2 i.v.) was given on day 1. Survival curves were generated using the Kaplan-Meier method. RESULTS: Among 35 eligible patients, 3 showed a complete response and 27 a partial response, with an overall response rate of 85.7%. No patient showed progressive disease. Thirty-three patients were able to undergo radical surgery after neoadjuvant chemotherapy and only 2 patients (stage IIIb) received radiotherapy without the optimal surgery. The median disease-free survival (DFS) period was 42 months (range 5-73). The median overall survival (OAS) period was 44 months (range 17-74). Two-year DFS and OAS rates were 74.3% and 91.4%, respectively. Of the 58 treatment cycles administered, grade 3 or 4 neutropenia and thrombocytopenia were observed in 50% and 9% of the treatment cycles, respectively. Grade 3 or 4 diarrhea was observed in 6%. CONCLUSION: Neoadjuvant chemotherapy with CPT-11 and MMC can be effective and well-tolerated against locally advanced SCC of the uterine cervix.
