Abstract

Purpose: The aim of the study was to compare high-versus low-dose cisplatin in combination with cyclophosphamide and epidoxorubicin as primary chemotherapy for suboptimal stage III and IV ovarian cancer. Patients and Methods: One hundred forty-five patients were randomized to receive six courses of cisplatin 50 or 100 mg/m2 plus epidoxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2. The two treatment arms were well balanced; all patients had greater than 2 cm and 37.2% had greater than 5 cm of residual disease; 29.6% had stage IV disease. Results: Patients in the high-dose arm received a double dose-intensity and double total dose of cisplatin. The high-dose regimen induced significantly more episodes of leukopenia (47.8% v 32.8%, P = .05), thrombocytopenia (21.7% v 3.2%, P = .003), anemia (37.6% v 12.5%, P = .002), nephrotoxicity (six v one patient), and neurotoxicity (30.4% v 6.3%, P = .002). There were no significant differences in efficacy in terms of clinical response rate (high-dose 57.5% v low-dose 61.1%), pathologic complete response (CR) (9.6% v 18.1%), median survival times (29 v 24 months), and median progression-free survival (18 v 13 months). Conclusion: This study shows that doubling the dose-intensity and total dose of cisplatin in combination with epidoxorubicin and cyclophosphamide has significant toxic effects and does not improve clinical outcome in patients with suboptimal ovarian cancer.
