Popis: | Background Because of the single-agent activity of irinotecan hydrochloride, combination of irinotecan and docetaxel treatment against metastatic breast cancer (MBC) should be evaluated. Patients and methods Single-stage phase 2 study of irinotecan and docetaxel to evaluate tumor response, toxicity, time to progression, and overall survival was carried out. Regimen of docetaxel (25 mg/m2) and irinotecan (70 mg/m2) was administered on days 1 and 8 of each 3-week cycle. Patients had histologically confirmed breast adenocarcinoma and metastatic cancer measurable with RECIST. Results Of 70 patients enrolled, 64 were assessable. Prior treatment with an anthracycline and a taxane was required. Eighteen (28%) patients [95% confidence interval (CI) 15% to 31%] had tumor response, plus four patients had stable disease (less than 30% decrease in sum of longest diameter and less than 20% increase) for >6 months. The clinical benefit rate was 34% overall. Median duration of tumor response was 6.7 months (95% CI 4.2–37.7 months); median follow-up was 18.6 months (range 8.5–37.7 months). The most common severe adverse events included fatigue [n = 16 (25%)] and neutropenia [n = 13 (20%)]. Conclusions Weekly dosing of combination of irinotecan and docetaxel is active against MBC. However, the response rate to our regimen was not significantly better than single-agent docetaxel. Other schedules of irinotecan plus docetaxel should be considered for future studies. |
