PURPOSE: To evaluate the role of surgical debulking in patients with stage IV ovarian cancer. METHODS: We conducted a retrospective review of patients with advanced epithelial ovarian cancer treated at M. D. Anderson Cancer Center. Eligible patients included women with stage IV disease treated with platinum-based chemotherapy. Surgical debulking was considered optimal if the diameter of the largest residual tumor was 2 cm or less. Survival analysis and comparisons were performed using the Kaplan-Meier method and the log-rank test. RESULTS: One hundred eight women with stage IV ovarian cancer were identified. The extraperitoneal metastatic sites were the liver parenchyma in 16 patients, the pleura in 54 patients, a variety of other organs in 22, and two or more sites in the remaining 16. Median age of the patient population was 58 years (range 35-81 years). Surgery to reduce the primary tumor was performed in 100 patients. The procedures included salpingo-oophorectomy with or without hysterectomy in 94 patients, omentectomy in 90, small bowel resection in 4, large bowel resection in 23, and splenectomy in 2. At the completion of surgery, tumor reduction was considered optimal in 31 patients, suboptimal in 61, and undetermined in 8. The overall median survival for optimally debulked patients was 25 months compared to 15 months for suboptimally debulked patients (P < 0.02). The progression-free survival, on the other hand, was not statistically different between the two groups. CONCLUSION: Residual tumor seems to be an important prognostic factor in patients with stage IV ovarian cancer. Surgical debulking may play a significant role in the treatment of these patients.
