The Prognostic Impact of Tumor Differentiation on Recurrence and Survival after Resection of Hepatocellular Carcinoma Is Dependent on Tumor Size

The present study aimed to evaluate the effect of poor differentiation and tumor size on survival outcome after hepatic resection of hepatocellular carcinoma (HCC).A total of 1,107 patients who underwent initial and curative hepatic resection for HCC without macroscopic vascular invasion participated in the study. Using the multivariable Cox proportional hazards regression model, we evaluated changes in hazard ratios (HRs) for the association...
