The neoadjuvant approach in the treatment of patients with advanced epithelial ovarian carcinoma.

Abstract

AIMS: Ovarian cancer has a very poor prognosis, with 5-year survival rates of 5-20% for advanced-stage disease. This work was designed to verify whether the neoadjuvant approach had an effect on survival in patients with advanced-stage ovarian cancer. MATERIALS AND METHODS: Patients with stage III or IV disease who received neoadjuvant platinum-based chemotherapy (group 1) were compared with a group of conventionally treated patients (group 2). RESULTS: Most of the patients in group 1 (76%) had partial tumoral responses after chemotherapy. Patients from group 1 (n = 42) had a median survival that was not different from that in patients from group 2 (n = 348). Patients who received platinum-based chemotherapy with taxanes had the same survival of patients who received no taxanes. CONCLUSIONS: Our results showed similar responses and survival rates for patients with stage III or IV ovarian cancer treated with neoadjuvant platinum-based chemotherapy, when compared with patients who underwent primary suboptimal cytoreductive surgery. Our data therefore support the ongoing trials to determine the optimum timing of surgery for ovarian cancer.
