During the past two decades, maximum cytoreductive surgery (also called debulking surgery) has been the recommended surgical approach for advanced stages of ovarian carcinoma. The residual tumor volume after surgery is one of the strongest prognostic factors, and only patients who undergo complete or optimal surgery are likely to be long-term survivors (i.e., 50% after five years). A well-trained surgeon in the field of gynecologic oncology can achieve an optimal tumor reduction in up to 75% of patients with advanced stage ovarian cancer. During the procedure, bowel resection, especially rectosigmoid, must be undertaken in 30% to 40% of cases, and para-aortic and pelvic lymphadenectomy should be performed after adequate tumor reduction in the abdominal cavity. The experienced surgeon can perform these surgeries with an acceptable morbidity, allowing chemotherapy to be undertaken within the month following surgery. However, very advanced cancer with massive peritoneal carcinomatosis and/or Stage IV disease requires a very aggressive surgical procedure but yields a poor prognosis and a higher risk of unacceptable complications. For these worst cases, the concept of cytoreductive surgery is moving toward the alternative strategy of chemosurgical cytoreduction, in which interval cytoreductive surgery is undertaken after three cycles of front-line chemotherapy. The goal of this experimental strategy is to achieve a complete tumor response after front-line chemosurgical therapy, and a better quality of life.
