High preoperative serum globulin in hepatocellular carcinoma is a risk factor for poor survival

Background: Serum globulin (GLB), albumin (ALB) and albumin/globulin ratio (AGR) have been reported as prognosis related factors for certain malignancies; however, the prognostic value of globulin (GLB) in hepatocellular carcinoma (HCC) has rarely been studied. This study was performed to evaluate whether GLB analysis could be applied for the prediction of the prognosis of patients received liver resection. Methods: A training cohort study involving 210 HCC patients undergoing curative liver resection between January 2007 and December 2012, and a validation cohort involving 100 HCC patients contemporaneously undergoing curative liver resection in another set were recruited. The survival curves were graphed and log-rank test was performed to analyze the differences between the curves. The cutoff value was selected by X-title program. Results: Univariate and multivariate analysis indicated that high serum GLB level is a risk factor for poor cancer-specific survival (CSS) (P < 0.05). Conversely, high ALB level is a prediction for favor CSS (P = 0.010). Conclusions: We identified the preoperative high GLB level as a prognostic risk factor for patients after treatment of liver cancer resection. This easily obtained variable may act as an available clinical biomarker to predict the prognosis of such patients.
