Purpose: A multicenter phase II study to evaluate the antitumor effect and safety of docetaxel in combination with cisplatin as first-line chemotherapy for advanced ovarian cancer.
Methods: Enrolled in the study were 45 patients who were to receive six courses of docetaxel 75 mg/m(2) plus cisplatin 75 mg/m(2) every 21 days with hydration and steroid prophylaxis after initial debulking surgery. Imaging techniques and radiography were used to assess clinical tumor response, and second-look surgery was required for patients with complete clinical responses and for those without clinically measurable disease.
Results: The overall clinical response rate in 29 patients with clinically measurable disease was 58% (41% complete response). A complete pathologic response was seen in 9 of 34 patients who underwent second-look laparotomy, while microscopic disease was found in 10 patients. The median time to progression was 14.4 months (95% CI 8.4-20.4 months), with a median overall survival of 43 months (95% CI 21.1-65.0 months). Patients received a median number of six cycles at a dose intensity of 98%. Grade 3-4 neutropenia was seen in 80% of patients, but was manageable. No patients withdrew because of fluid retention.
Conclusions: The combination of docetaxel with cisplatin confers high clinical and pathologically verified tumor response rates and is well tolerated in the first-line management of advanced ovarian cancer.
