title: The clinical significance of hepatic parenchymal metastasis in patients with primary epithelial ovarian cancer.
abstract: OBJECTIVE
  The objective of this study was to determine the clinical significance of hepatic parenchymal metastasis on survival in patients with advanced epithelial ovarian cancer.
  
  
  METHODS
  We conducted a retrospective review of ovarian cancer patients with stages IIIc and IV hepatic parenchymal metastasis who were treated at the National Cancer Center in Korea between January 2001 and January 2008. Hepatic metastases were divided into unresectable, hematogenous parenchymal metastasis and resectable, parenchymal metastasis from peritoneal seeding.
  
  
  RESULTS
  One hundred twenty patients were identified, 113 of whom were included in the study. The stage IIIc group included 97 patients, and the group with stage IV disease and hepatic parenchymal metastasis included 16 patients. Of the 16 patients with hepatic parenchymal metastasis, 2 patients had unresectable, hematogenous parenchymal metastasis with a poor prognosis compared to the patients with resectable, hepatic parenchymal metastasis from peritoneal seeding. Fourteen patients with hepatic parenchymal metastases from peritoneal seeding underwent complete resection without complications as follows: wedge resection (n=7), segmentectomy (n=5), and hemi-hepatectomy (n=2). Age, tumor grade, histology, serum CA-125 level, and the rate of optimal debulking were similar in patients with stage IIIc disease and patients with stage IV disease who had resectable, hepatic parenchymal metastasis from peritoneal seeding. The 5-year progression free survival rate and the 5-year overall survival rate for patients with stage IIIc disease and patients with stage IV disease and hepatic parenchymal metastasis from peritoneal seeding were 25 and 23% (p=0.8063), and 55 and 51% (p=0.5671), respectively.
  
  
  CONCLUSIONS
  Our findings suggest that complete hepatic resection should be attempted for patients with hepatic parenchymal metastasis from peritoneal seeding.
