Biweekly administration of docetaxel and carboplatin for advanced or recurrent endometrial and ovarian carcinomas.

OBJECTIVE: To examine efficacy and safety of biweekly administration of docetaxel and carboplatin for advanced or recurrent en- dometrial and ovarian carcinomas. MATERIAL AND METHODS: The recommended doses were determined in the phase I study. In the phase II feasibility study, the primary end-point was safety, and the secondary end-point was response rate and progression-free survival (PFS). RESULTS: The recommended doses of docetaxel and carboplatin were determined to be 45 mg/n(2) and AUC 3.0, respectively, in phase I study. In phase II feasibility study, no treatment-related death was observed. Most non-hematotoxicity cases were mild or moderate. Grade 4 neutropenia was confirmed in 13 patients (31.0%), whereas all cases showed tolerability with 2.6 days delay of anticancer drugs administration in both groups. Response rate was 55.0% in the ovarian carcinoma group, and average PFS was 8.7 months. In the endometrial carcinoma group, response rate was 50.0% and average PFS was 32.0 months. CONCLUSION: The present results showed that biweekly administration of docetaxel and carboplatin for advanced and recurrent endometrial and ovarian carcinomas results in acceptable side effects, response rate, and PFS.
