title: Hepatic resection for metachronous metastases from ovarian carcinoma.
abstract: OBJECTIVE
  Hepatic resection for recurrent ovarian carcinoma is controversial because of the paucity of relevant published data. The principles of cytoreduction before chemotherapy suggest that resection of measurable liver lesions in properly selected patients would be beneficial. To determine the effect of resection of metachronous liver metastases on morbidity and survival, we reviewed our experience with this treatment.
  
  
  METHODS
  Medical records were reviewed retrospectively for all patients who had anatomic hepatic resection for metachronous parenchymal liver metastases from ovarian carcinoma (epithelial or malignant mixed Müllerian tumors) at Mayo Clinic from 1976 to 1999.
  
  
  RESULTS
  We identified 26 patients (median age at hepatic resection, 62 years; range, 39-75 years) who had hepatic resection requiring complete segmentectomies or more extensive hepatic surgery for recurrent ovarian carcinoma. Cytoreduction was optimal (extrahepatic and hepatic residual disease <or=1 cm) in 21 patients and suboptimal in 5. No intraoperative or postoperative deaths occurred. Aside from blood loss requiring transfusion of more than 4 units of erythrocytes in 4 patients, only two complications were noted: one superficial wound infection and one small-bowel perforation that required reoperation. The overall median disease-related survival was 26.3 months after hepatic resection; 18 patients (69%) died of disease at a median of 14.6 months (range, 5.0-41.3 months). However, 8 patients (31%) were alive at median follow-up of 33.2 months (range, 3.6-49.6 months). Factors significantly associated with improved disease-related survival were consistent with known prognostic factors associated with cytoreductive surgery, including more than 12 months since original diagnosis (27.3 vs 5.7 months, P = 0.004) and less than or equal to 1 cm of residual disease after hepatic resection (27.3 vs 8.6 months, P = 0.031).
  
  
  CONCLUSIONS
  We present evidence that hepatic resection can be performed with minimal surgical morbidity and mortality by surgical teams trained in the procedures. Because of the disease-related survival advantage afforded women by optimal cytoreductive surgery, parenchymal liver metastases should not preclude secondary cytoreductive surgical efforts.
