Effect of PIVKA-Ⅱ and AFP levels on the prognosis of patients with HBV infection-related hepatocellular carcinoma / 中国实用内科杂志

ABSTRACT

OBJECTIVE: To evluated the prognostic potential of preoperative PIVKA-Ⅱ and AFP to the patients of HBV infection-related hepatocellular carcinoma(HCC) after radical resection. METHODS: Chronic HBV infection-related HCC patients who undergone resection in the Affiliated Cancer Hospital of Zhengzhou University from 2009 to 2013 with competed data of clinical information,laboratory results and follow-up records were enrolled our study. Finaly, a total of 107 subjects entered our research. PIVKA-Ⅱ was quantitatively measured by Chemiluminescence methods. Kaplan-Meier survival analysis and the Cox proportional hazards model were used to analyze the factors which can affect patient's post surgery survival. RESULTS: Kaplan-Meier survival curve analysis showed that the 1-,2-,3-year survival rate of the patients with high PIVKA-Ⅱ level were 56%, 28% and 16%, respectively, much poor than that of patients with low PIVKA-Ⅱ level, the 1-,2-,3-year survival rate for the latter were 73%, 54% and 46%, respectively(P = 0.002). The 1-,2-,3-year survival rates for patients with high AFP levels were 58%, 35% and 25%, respectively, and the the 1-,2-,3-year survival rates for patients with low AFP levels were 83%, 63% and 51%, respectively(P = 0.006). Multivariate factor results showed that high PIVKA-Ⅱ levels, high AFP levels, the presence of portal vein tumor thrombus and incomplete capsular were independent risk factors for prognosis,HR(95% CI) were 1.99(1.15-3.45), 2.03(110-3.76), 2.72(1.53-4.83) and 2.07(1.07-4.00), respectively. In addition, the prognosis would got worse with the superposition of four independent risk factors. CONCLUSION: Preoperative PIVKA-Ⅱ and AFP levels are associated with HCC patients' s poor post surgery prognosis.
