Hepatic resection for recurrent metastatic ovarian carcinoma or peritoneal carcinoma: a retrospective case-control study

Purpose of investigation: This study was performed to investigate the validity of hepatic resection as a treatment option for hepatic parenchymal metastasis in patients with recurrent epithelial ovarian carcinoma or primary peritoneal carcinoma. Materials and Methods: A retrospective case-control study was conducted. Fisher's exact test and Kaplan-Meier analysis were used to analyze the clinicopathologic characteristics and survival of 40 patients with hepatic parenchymal metastasis from recurrent ovarian carcinoma or primary peritoneal carcinoma. Results: Of these 40 patients, 12 characterized by unilobar metastasis underwent hepatic resection as part of secondary cytoreductive surgery, while 28 underwent only salvage chemotherapy. The median overall survival time from the time of the liver metastasis was significantly longer in patients who underwent hepatic resection as part of secondary cytoreduction than those who underwent salvage chemotherapy (62 vs. 14 months, respectively; p = 0.04). Conclusion: Hepatic resection has the potential to improve survival for patients with hepatic parenchymal metastasis from recurrent ovarian carcinoma or primary peritoneal carcinoma.
