Prognostic Significance of Globulin/Low-Density Lipoprotein Ratio In Patients With Hepatocellular Carcinoma After Local Ablative Therapy
Abstract Background: Low-density lipoprotein (LDL) and globulin have been found to be predictors for some malignant tumors, but their predictive value in hepatocellular carcinoma (HCC) has hardly to be elucidated. This study assessed the prognostic significance of globulin to low-density lipoprotein ratio (GLR) in HCC patients before ablation.Materials and methods: This study analyzed 312 HCC patients hospitalized and underwent ablative treatment in Beijing You 'an Hospital, Capital Medical University, from January 1, 2012 to January 1, 2017. Cox regression analysis was used to assess the factors independently associated with recurrence and survival. The optimal cut-off value and prognostic role of GLR and other markers were evaluated via the receiver operating characteristic-ROC curves and the Youden index. Overall survival (OS) and recurrence-free survival (RFS) were calculated by Kaplan-Meier analysis, and compared between groups using the log-rank.Result: Univariate and multivariate analysis found that the tumor number (HR: 1.676;95%CI: 1.113-2.526), tumor size (HR: 1.967;95%CI: 1.251-3.092), GLR (HR: 1.028;95%CI: 1.004-1.052) were independent risk factors of relapse; while etiology (HR: 1.328;95%CI: 1.052-1.677), tumor number (HR: 1.615;95%CI: 1.015-2.570), tumor size (HR: 2.061; 95%CI: 1.243-3.418), Fib (HR: 0.73; 95%CI: 0.535-0.996) and GLR (HR: 1.031;95%CI: 1.003-1.06) were related to overall survival. We classified the patients into groups with high and low levels of GLR based on the optimal cut-off value of GLR identified by generating receiver operating characteristics (ROC) curve. The cumulative 1-, 3-, and 5-year RFS rates in the low GLR group were 76.4%, 53.8% and 43.4%, while those in the high GLR group were 71%, 31% and 22%, respectively (P <0.001). Concerning OS, the low GLR group showed a 1-, 3- and 5-year OS of 99.5%, 92.0% and 80.2% versus 98%, 73% and 63% for the high GLR group (P <0.001). Finally, patients were stratified by GLR and tumor size. The outcomes revealed that patients in group A (GLR<16.54 and tumor size ≤30mm) showed better prognosis than group B (GLR≥16.54 and tumor size≤30mm or GLR<16.54 and tumor size >30mm) and group C (GLR≥16.54 and tumor size >30mm) (P <0.001). Conclusions: Preoperative GLR ratio could serve as a biomarker to predict prognosis in HCC patients who underwent complete ablation.
