KIAA0101 always overexpresses in tumor tissues, which is also a marker of tumor recurrence. This study aims to explore whether overexpression of KIAA0101 mRNA in peripheral blood mononuclear cells (PBMCs) could act as a noninvasive and predictive biomarker of hepatic cancer. Real-time polymerase chain reaction (RT-PCR) was employed to detect KIAA0101 mRNA expression in PBMCs isolated from 93 hepatic cancer patients and 55 healthy individuals. The diagnostic sensitivity and specificity of KIAA0101 mRNA, CEA, and CD44V were analyzed and compared. A multivariate logistic regression analysis was utilized to analyze risk factors for overall survival of hepatic cancer patients. A concordance analysis was employed to compare the overexpression of KIAA0101 mRNA with clinicopathological diagnosis. All of the 93 hepatic cancer patients were followed up routinely at least 36 months or until death to analyze the 3-year overall survival rate. The results indicated that KIAA0101 mRNA expression was increased significantly in hepatic patients' PBMCs, when compared with that of healthy individuals (P < 0.05). Both the sensitivity and specificity of KIAA0101 mRNA in PBMCs were enhanced significantly compared with those of the CEA and CD44V biomarkers. The multivariate logistic regression analysis indicated that the KIAA0101 mRNA level and pTNM stage were significantly related with the overall survival of the hepatic patients. There was a better concordance between KIAA0101 mRNA overexpression and clinicopathological diagnosis for hepatic cancer (kappa = 0.914, P < 0.001). KIAA0101 mRNA overexpression in PBMCs decreased the 3-year survival rate significantly. In conclusion, overexpression of KIAA0101 mRNA in PBMCs could act as a predictive biomarker for hepatic cancer and has a better sensitivity and specificity.
