Abstract
OBJECTIVE: Epithelial ovarian cancer and relapsed type II endometrial cancer share common characteristics. Although the role of intraperitoneal (IP) chemotherapy in the treatment of epithelial ovarian cancer has been well-established, its role in the treatment of relapsed type II endometrial cancer remains to be elucidated. MATERIAL AND METHODS: From January 2000 to December 2012, patients who were diagnosed with relapsed type II endometrial cancer and underwent secondary cytoreductive surgery, patients with residual tumors less than 1 cm in diameter were initially screened for this study. Of the screened patients, consecutive patients who received salvage IP chemotherapy (IP platinum plus intravenous paclitaxel) were considered the case group. The case study group was matched to a control group that was composed of patients who received salvage systemic chemotherapy (intravenous platinum plus intravenous paclitaxel) in a 1:2 ratio. The overall survival was compared between the case group and the control group, and the IP treatment-related toxicities were reported. RESULTS: In total, 11 patients were assigned into the case group and 22 patients were assigned into the control group. The median overall survival (95% confidence interval) was 40.5 (25.5-56.2) months for the case group versus 28.0 (18.0-37.0) for the control group (hazard ratio=0.37 (95% confidence interval, 0.15-0.95); p=0.032, by the log-rank test). The most commonly observed toxicity was of gastrointestinal origin (81.8%). Toxicities that stemmed from hematological, cardiovascular, neurological, and catheter-related complications were similar to results published in other studies on IP chemotherapy for ovarian cancer. CONCLUSION: Salvage IP chemotherapy may potentially confer a longer overall survival than conventional systemic chemotherapy in the treatment of relapsed type II endometrial cancer.
