Post-operative sequential high-dose chemotherapy with haematopoietic stem cell support as front-line treatment in advanced ovarian cancer: a phase II multicentre study.
In spite of multimodal management including aggressive surgery and chemotherapy, the prognosis of advanced ovarian cancer (AOC) remains poor. Multicycle high-dose chemotherapy (HDC) with haematopoietic stem cell (HSC) support has been shown to be a promising procedure in various cancers including AOC. We conducted a phase II multicentre study to evaluate feasibility, toxicity and efficacy of post-operative front-line sequential HDC with HSC support in AOC. Thirty four patients with stage IIIC/IV received a post-operative sequential combination of high-dose cyclophosphamide/epirubicin (D1, D21) with HSC harvesting, high-dose carboplatin (D42, D98) followed by HSC infusion, and dose-dense paclitaxel (D63, D77, D119, D133). Rh-G-CSF (filgrastim) was administered following all cycles. Primary endpoint was pathological complete response rate (pCR). Thirty patients received at least 7 of the scheduled 8 cycles. Haematological toxicity was significant but manageable. Grade 3/4 extra-haematopoietic toxicities were relatively uncommon and reversible. No toxicity-related death was observed. The observed pCR was 37% and did not reach the initial endpoint. Post-operative front-line sequential HDC in AOC is feasible and safe in a multicentre setting. The observed pCR does not support a clear advantage over conventional treatment. This approach remains an experimental strategy to further optimise and validate.
