BACKGROUND: Presently, the impact of @entity5 size as a prognostic factor after curative liver resection (LR) for @entity157 ( @entity157 ) remains controversial. This study was performed to determine the prognostic factors of @entity1 undergoing LR for solitary @entity157 with special emphasis on the importance of @entity5 size. METHODS: Between 2000 and 2013, 560 @entity1 underwent curative LR for solitary primary @entity157 which met the study criteria. RESULTS: One-hundred and seventy-eight @entity1 underwent major hepatectomies and the overall in-hospital mortality was 2.0%. There were 282 @entity1 (50.4%) with @entity1575 . The 5-year @entity1349 ( @entity1349 ) was 64% and @entity1349 ( @entity1349 ) was 50%, respectively. Multivariate analyses demonstrated that @entity82 , microvascular invasion and size were independent predictors of @entity1349 and @entity82 , microvascular invasion and age were independent prognostic factors of @entity1349 . Subset analysis demonstrated that @entity5 size was a prognostic factor for solitary @entity157 with microvascular invasion (AJCC T2) but not solitary @entity157 without microvascular invasion (AJCC T1). CONCLUSIONS: Size, microvascular invasion, and @entity82 are independent prognostic factors of @entity1349 for solitary @entity157 after LR. @entity5 size is an important prognostic factor in T2 but not T1 solitary @entity5 . These findings suggest that the current AJCC TNM staging system may need to be revised. J. Surg. Oncol.    2015 Wiley Periodicals, Inc.
