The Role of Neoadjuvant Chemotherapy in the Treatment of Advanced Ovarian Cancer

Primary cytoreductive surgery followed by chemotherapy represents the current standard treatment for patients with advanced ovarian cancer. Neoadjuvant chemotherapy followed by interval debulking surgery has been proposed as an alternative approach for the initial management of bulky ovarian cancer, aiming at the improvement of surgical efficiency and patients’ quality of life. According to the hitherto published studies, consisting mainly of retrospective observations, neoadjuvant chemotherapy followed by interval cytoreduction appears to improve the prognosis and quality of life in selected groups of patients. The survival outcome in these patients is similar to that of the conventional approach, or even better in some of the cases. Moreover, patients undergoing debulking surgery after having received neoadjuvant chemotherapy had a reduced perioperative morbidity compared to patients undergoing primary cytoreduction. Concurrently, neoadjuvant chemotherapy provides preoperative knowledge of tumor chemosensitivity, hence allowing the surgeon to choose appropriately aggressive treatment. However, until the results of prospective randomized trials become available, neoadjuvant chemotherapy followed by interval surgery should be applied only to individual cases and primarily in the context of clinical trials.
