Neoadjuvant chemotherapy for advanced ovarian cancer.

The purpose of this study was to compare the survival of women with clinical, radiologic, and histologic findings compatible with advanced ovarian cancer who were treated with neoadjuvant chemotherapy to that of a group of women with FIGO stage IIIC (suboptimal debulking) and stage IV epithelial ovarian cancers treated with the same chemotherapy. Eleven women with physical, radiologic, and histologic findings compatible with advanced ovarian cancer (median age, 73 years) treated with neoadjuvant carboplatin and cyclophosphamide chemotherapy were compared to 18 women (median age, 60 years) who had stage III and suboptimal surgical cytoreduction (> 2 cm residual tumor, 13 patients) or stage IV (5 patients) ovarian cancer followed by the same chemotherapy. The progression-free survival for the 11 women receiving neoadjuvant chemotherapy was 9.1 months which was not statistically different from the 8.5 months progression-free survival for the 18 women with suboptimally debulked stage IIIC or stage IV disease (P = 0.98). The overall survival was not significantly different (P = 0.26). Neoadjuvant-treated patients tended to tolerate chemotherapy better as none required dose reduction for bone marrow suppression, while 6 of 18 conventionally treated patient required dose reductions. In conclusion, neoadjuvant chemotherapy appears to be an effective means of palliating women with clinical, radiological, and histologic findings compatible with advanced ovarian cancer. A prospective study is necessary in which women with findings compatible with advanced ovarian cancer that is not likely to be effectively cytoreduced surgically are randomized to either undergo cytoreductive surgery followed by chemotherapy or receive neoadjuvant chemotherapy.
