OBJECTIVE: Results of the ICON4/AGO-OVAR-2.2 trial suggest that a platinum/taxane combination provides a survival benefit in relapsed, platinum-sensitive ovarian cancer compared to platinum alone. The optimal specific combination has yet to be determined. The current study evaluates weekly docetaxel and carboplatin in this setting. METHODS: Using a prospective phase II design, patients received weekly docetaxel (35 mg/m2) and carboplatin (AUC=2) administered days 1, 8, and 15 of a 28-day cycle. Initial treatment with a platinum-based regimen was required, with a treatment-free interval of at least 3 months. Patients could have received one prior regimen for recurrence. Biologically evaluable disease (CA-125) could be followed only if measurable disease was not present. Quality of life analysis utilized the FACT-O and FACT/GOG-Ntx scales. RESULTS: Thirty-six patients enrolled in the trial over 29 months. The majority had ovarian cancer (89%) and stage III/IV (97%) disease, with a median initial disease-free interval of 12 months. Most subjects were treated for first recurrence (81%) and had measurable disease (58%). The overall response rate was 67% (PR=52%, CR=15%), with 22% stable disease. Grade 3/4 neutropenia was common (48%) while serious anemia and thrombocytopenia were not. Neuropathy was generally mild and manageable. Carboplatin hypersensitivity led to 11 subjects coming off trial (31%). Diphenhydramine premedication produced a nonsignificant decrease in reaction rate. There was no detectable difference in quality of life due to therapy. CONCLUSION: The weekly regimen of carboplatin and docetaxel has a good response rate with an acceptable toxicity profile.

Carboplatinhypersensitivity led to 11 subjects coming off trial (31%). Diphenhydramine premedication produced a nonsignificant decrease in reaction rate. There was no detectable difference in quality of life due to therapy. CONCLUSION: The weekly regimen of carboplatin and docetaxel has a good response rate with an acceptable toxicity profile.
