High-dose chemotherapy for ovarian carcinoma: Long-term results from the solid tumour registry of the European group for blood and marrow transplantation (EBMT)

Abstract

Purpose: to determine the outcome of epithelial ovarian cancer in patients registered with the European Group for Blood and Marrow Transplantation (EBMT). Patients and methods: A retrospective analysis was performed on 254 patients with advanced or recurrent disease, median age 46 years (14-63) from 39 centres treated between 1982 and 1996. Only 25% of patients were known to have no or microscopic disease after initial surgery; in approximately 20% the disease status was unknown, the remainder had macroscopic disease. Results: One hundred five patients received high-dose chemotherapy in complete or very good partial remission, twenty-seven in second remission and the remainder in the presence of residual disease. Most received melphalan or carboplatin, or a combination (86%) supported by autologous bone marrow or peripheral blood stem cells. The survival of patients treated in remission was significantly better than in other groups (median 33 vs. 14 months; P = 0.0001). The durability of remission was longer after transplantation in first remission than in second remission (median disease-free survival 18 vs. 9 months; P = 0.005). With a median follow-up of 76 months from diagnosis the median disease-free and overall survival in stage III disease transplanted in remission is 42 and 59 months and for stage IV disease 26 and 40 months. Conclusions: High-dose chemotherapy has a potential benefit for patients in remission. The results support the conduct of randomised studies to determine whether there is a real value from this treatment.
