Abstract
Since 1981, over 300 patients reported with advanced or refractory ovarian cancer have been treated with high-dose chemotherapy supported by autologous bone marrow or peripheral blood stem cell transplantation. Partial or complete clinical response has been reported in 54–100% of the cases, but the median duration of the response in the majority of patients has been only a few months. It is obvious from the available data that high-dose regimens supported by autologous stem cell transplantation (ASCT) are not capable of inducing long-term survival in patients with heavy tumour burden or chemoresistant ovarian cancer. Recent reports on nearly 100 patients have described results of the use of high-dose chemotherapy as first-line treatment for patients with optimally debulked disease or negative second-look laparotomy. Response rates and survival have been better when compared to historical controls, but the efficacy of this treatment modality in inducing durable remission has not been tested in randomized trials. Most of the ongoing trials presented briefly in this review have been designed to evaluate the potential of high-dose therapy as first-line treatment in preventing the development of resistant tumour clones and recurrence. The role of sequential high-dose chemotherapy with ASCT as a part of primary treatment or as salvage therapy for chemosensitive recurrent disease is also under investigation.
