BACKGROUND: Platinum rechallenge or weekly topotecan in combination have not been evaluated in randomized trials for resistant recurrent ovarian cancer (ROC).
METHODS: Patients with ROC after first- or second-line treatment including a platinum and taxane and progression within 6 months were randomized to weekly paclitaxel (wP, 80 mg/m(2)/week) alone or in combination with carboplatin (C, area under the curve of 5 mg/ml/min every 4 weeks) or weekly topotecan (wT, 3 mg/m(2)/week). Primary end point was progression-free survival (PFS) comparing wP and combination therapy.
RESULTS: Patients (n = 165) received a median three cycles in each arm. Nonhematologic toxicity was not different, except increased hypersensitivity reactions with wP + C. Grade 3-4 hematologic toxic effects with wP, wP + C, and wP + wT, respectively, were neutropenia in 13%, 54%, and 42%; febrile neutropenia in 0%, 4%, and 5%; and anemia in 6%, 19%, and 29%. Response rates were 35%, 37%, and 39%, and median PFS times were 3.7, 4.8, and 5.4 months, respectively. PFS was not significantly different among the treatment arms [hazard ratio (HR) 0.922; 95% confidence interval (CI) 0.765-1.111; P = 0.46]or between monotherapy and combination therapy (HR 0.951; 95% CI 0.686-1.318; P = 0.76).
CONCLUSIONS: Combination chemotherapy in platinum-resistant ROC was more toxic than weekly paclitaxel and did not significantly prolong PFS.
