During the past two decades, maximum cytoreductive surgery (also called deb
ulking surgery) has been the recommended surgical approach for advanced sta
ges of ovarian carcinoma. The residual tumor volume after surgery is one of
the strongest prognostic factors, and only patients who undergo complete o
r optimal surgery are likely to be long-term survivors (i.e., 50% after fiv
e years). A well-trained surgeon in the field of gynecologic oncology can a
chieve an optimal tumor reduction in up to 75% of patients with advanced st
age ovarian cancer. During the procedure, bowel resection, especially recto
sigmoid, must be undertaken in 30% to 40% of cases, and para-aortic and pel
vic lymphadenectomy should be performed after adequate tumor reduction in t
he abdominal cavity. The experienced surgeon can perform these surgeries wi
th an acceptable morbidity, allowing chemotherapy to be undertaken within t
he month following surgery. However, very advanced cancer with massive peri
toneal carcinomatosis and/or Stage IV disease requires a very aggressive su
rgical procedure but yields a poor prognosis and a higher risk of unaccepta
ble complications. For these worst cases, the concept of cytoreductive surg
ery is moving toward the alternative strategy of chemosurgical cytoreductio
n, in which interval cytoreductive surgery is undertaken after three cycles
of front-line chemotherapy. The goal of this experimental strategy is to a
chieve a complete tumor response after front-line chemosurgical therapy, an
d a better quality of life. Semin. Surg. Oncol. 19:42-48, 2000. (C) 2000 Wi
