OBJECTIVE: To assess the surgical results and clinicopathologic features of hepatic metastases from @entity356 to identify @entity1 with a better probability of survival. SUMMARY BACKGROUND DATA: Many studies have reported the benefit of hepatic resection for @entity3 from @entity14 . However, indications for a surgical approach for @entity356 involving the liver have not been clearly defined. METHODS: Ninety (11%) of 807 @entity1 with primary @entity356 were diagnosed with synchronous (n = 78) or metachronous (n = 12) hepatic metastases. Of these, 19 underwent 20 resections intended to cure the metastatic lesion in the liver. The clinicopathologic features of the hepatic metastases in, and the surgical results for, the 19 @entity1 were analyzed. RESULTS: The actuarial 1-year, 3-year, and 5-year survival rates after hepatic resection were, respectively, 77%, 34%, and 34%, and three @entity1 survived for more than 5 years after surgery. Solitary and metachronous metastases were significant determinants for a favorable prognosis after hepatic resection. Pathologically, a fibrous pseudocapsule between the @entity5 and surrounding hepatic parenchyma was found in 13 of the 19 @entity1 (68%). The presence of a peritumoral fibrous pseudocapsule and a well-differentiated histologic type of metastatic nodule were significant prognostic factors. Factors associated with the @entity75 were not significant prognostic determinants in @entity1 who underwent curative resection of the primary @entity5 . CONCLUSIONS: Solitary and metachronous metastases from @entity356 should be treated by a surgical approach and confer a better prognosis. A new prognostic factor, the presence of a pseudocapsule, may be helpful in defining indications for postoperative adjuvant treatment.
