Bottom Line: GPR and S-index were both found to be significantly associated with survival by univariate log-rank test.Multivariate analysis identified tumor size ≥5 and high level of GPR, but not high Barcelona Clinic Liver Cancer stage or S-index, as independent factors for predicting poor overall survival and recurrence-free survival.The GPR is an effective preoperative predictor for outcomes in hepatitis B-associated HCC.

ABSTRACT

Background: Several hepatic cirrhosis-derived noninvasive models have been developed to predict the incidence and outcomes of hepatocellular carcinoma (HCC). We aimed to investigate the prognostic significance of the two novel established cirrhosis-associated models based on gamma-glutamyl transpeptidase (GGT) and platelets in hepatitis B-associated HCC.

Methods: We retrospectively evaluated 182 HCC patients with positive hepatitis B surface antigen who received radical therapy at a single institution between 2002 and 2012. Laboratory data prior to operation were collected to calculate the GGT to platelets ratio (GPR) and the S-index. Predictive factors associated with overall survival and recurrence-free survival were assessed using log-rank test and multivariate Cox analysis. Additional analyses were performed after patients were stratified based on cirrhosis status, tumor size, therapy methods, and so forth, to investigate the prognostic significance in different subgroups.

Results: During a median follow-up time of 45.0 months, a total of 88 (48.4%) patients died and 79 (43.4%) patients recurred. The cut-off points for GPR and S-index in predicting death were determined to be 0.76 and 0.56, respectively. Compared with patients with a lower GPR, those with GPR ≥0.76 had a higher probability of cirrhosis and a larger tumor (both P<0.05). GPR and S-index were both found to be significantly associated with survival by univariate log-rank test. Multivariate analysis identified tumor size ≥5 and high level of GPR, but not high Barcelona Clinic Liver Cancer stage or S-index, as independent factors for predicting poor overall survival and recurrence-free survival.

Conclusion: The GPR is an effective preoperative predictor for outcomes in hepatitis B-associated HCC.

Mentions: Then we further evaluated the associations between the two models and cirrhosis. The area under the ROC curve was 0.639 (95% CI: 0.558–0.720, P=0.001) and 658 (95% CI: 0.579–0.737, P<0.001) for GPR and S-index, respectively, in detecting cirrhosis (Figure 1). Also, on comparing with these single parameters included in the models, they both showed a higher accuracy in predicting the presence of cirrhosis (Figure 1).
