Chik and colleagues report surgical outcome data on patients undergoing extended right-sided hepatic resections for hepatocellular carcinoma. This series of 172 patients older than 16 years included 82% of patients with underlying chronic liver disease and 26% with cirrhosis. Results are excellent, including an operative mortality of 8%, major morbidity of 14%, and disease-free survival of 9 months; overall survival was 34 months. Stratification of patients with tumors 10 cm or larger (n = 114) or smaller than 10 cm (n = 58) demonstrated a 5-fold increase in mortality in the patients with smaller tumors.

The authors correctly argue that this striking difference is related to a differential in residual liver function. One might not have predicted this inverse relationship between tumor size and morbidity and mortality. However, the data are clear and thus necessary to understand for anyone who performs liver resection. These results emphasize the importance of estimating . . . [Full Text of this Article]
