Are there candidates for high-dose chemotherapy in ovarian carcinoma?

Abstract : UNLABELLED: ABSTRACT: BACKGROUND: Prognosis of advanced ovarian carcinomas (AOC) remains poor with a 5-year survival of 30%. Benefit from high-dose chemotherapy (HDC) in this disease has not been demonstrated to date. METHODS: To evaluate the value of HDC as consolidation treatment after surgery and platinum/taxane-based therapy, we designed a monocentric retrospective comparative study. We used a subset approach to identify parameters associated with HDC efficacy. RESULTS: One hundred and three AOC patients treated with conventional chemotherapy alone (CCA) were compared to 60 patients receiving HDC plus hematopoietic stem cell support. After a median follow-up of 47.5 months there was no overall survival (OS) advantage for the HDC group in the whole population (p=0.29). Nevertheless, HDC was associated to a better outcome in young patients (≤50 years), both in term of progression-free survival (p=0.02, log-rank test) and OS (p=0.05, log-rank test). Median OS was 54.6 and 36 months in the HDC and CCA groups, respectively. CONCLUSIONS: Although randomized trials failed to demonstrate any benefit for HDC in AOC patients, this study suggests that young patients may derive a substantial advantage from receiving it after the standard treatment. Further prospective studies are warranted to confirm this gain and to search for the biological processes associated with this improvement.
