Abstract
Background: Although hepatectomy has been accepted as a therapeutic option for the primary tumor of hepatocellular carcinoma (HCC), what role the second liver resection will play in the clinical care of patients with intrahepatic recurrence of HCC after the initial resection has not been well evaluated. Study Design: In a retrospective review of the 6-year period between January 1991 and December 1996, records were examined of 94 patients who underwent curative liver resection for HCC. Of these, 57 patients had isolated recurrent disease to the liver; 12 of the 57 patients underwent repeat surgical resection and 45 patients received nonsurgical ablative therapy. Clinical data for these patients were reviewed for operative morbidity and mortality, survival, disease-free survival, and pattern of failure. Results: There were no perioperative deaths during repeat liver resections for recurrent HCC. Operative morbidity in the second resection was comparable to the initial resection. The disease-free survival rate after the second hepatectomy was 31% at 2 years, significantly lower than that after initial hepatectomy (62%) (p = 0.009). The overall survival rate after the second hepatectomy was 90% at 2 years, in contrast to 70% after nonsurgical ablative treatment for recurrent HCC (p = 0.253). Conclusions: Although the second liver resection for recurrent HCC can be performed safely and may improve survival, the disease-free survival rate after such resection therapy is low. This likelihood of further recurrences encourages studies for the selection of patients who may benefit from repeat liver resection.
