One attempt to improve results could be the addition of noncross-resistant drugs to platinum-paclitaxel combination regimens. Anthracyclines were among the candidates for incorporation as a third drug into first-line regimens. PATIENTS AND METHODS: We performed a prospectively randomized phase III study comparing carboplatin-paclitaxel (TC; area under the curve 5/175 mg/m2, respectively) with epirubicin 60 mg/m2 added to the same combination (TEC) in previously untreated patients with advanced epithelial ovarian cancer. All drugs were administered intravenously on day 1 of a 3-week schedule for a planned minimum of six courses. RESULTS: Between November 1997 and February 2000, 1,282 patients were randomly assigned to receive either TC (635 patients) or TEC (647 patients), respectively. Grade 3/4 hematologic and some nonhematologic toxicities (nausea/emesis, mucositis, and infections) occurred significantly more frequently in the TEC arm. Accordingly, quality-of-life analysis showed inferiority of TEC versus TC. Median progression-free survival time was 18.4 months for the TEC arm and 17.9 months for the TC arm (hazard ratio [HR], 0.95; 95% CI, 0.83 to 1.07; P = .3342). Median overall survival time was 45.8 months for the TEC arm and 41.0 months for the TC arm (HR, 0.93; 95% CI, 0.81 to 1.08; P = .3652). Similar nonsignificant differences were observed when strata were analyzed separately. CONCLUSION: Addition of epirubicin to TC did not improve survival or time to treatment failure in patients with advanced epithelial ovarian cancer; therefore, it cannot be recommended for clinical use in this population.
