Abstract
Introduction Despite the great achievements obtained in the early detection of hepatocellular carcinoma (HCC) through screening programs and application of targeted therapies with protease inhibitors such as sorafenib, the incidence [...]
Epidemiological data regarding hepatocellular carcinoma (HCC) report unsatisfactory morbimortality rates despite the global efforts to decrease the incidence and prolong patient survival. Current guidelines lack diagnostic biomarkers to better characterize patients with HCC. We aimed to validate the overexpression of Survivin-1, tumor-associated glyocoprotein 72 (Tag-72), and HECT and RLD domain containing E3 ubiquitin protein ligase 5 (HERC5) as tissue biomarkers for HCC characterization in patients from our geographical area and to standardize a local biomarker panel to be introduced in the current management guideline. Thirty samples of histologically confirmed HCC were compared to an equal number of samples of benign tumors in terms of Survivin-1, TAG-72, and HERC5 overexpression. Student's t-test, Mann-Whitney U test and Chi-square test were used to find differences between the two studied groups and to compare the categorical variables. The discriminative power of Survivin-1, Tag-72, and HERC5 overexpression was assessed using ROC curves. The multivariate linear regression analysis revealed that Survivin, Tag-72, and HERC5 were significantly overexpressed in older male patients, with [alpha]-fetoprotein (AFP) >200 ng/dl, low serum albumin, as well as in patients with imaging features of portal thrombosis and ascites. The diagnostic performance of Survivin-1, Tag-72 and HERC5 tissue biomarkers for HCC characterization was superior to that of the gold-standard AFP. Our study results validate the overexpression of Survivin-1, Tag-72, and HERC5 as tissue biomarkers for HCC characterization in patients from our geographical region and could be standardized in the current HCC management guideline.
