Abstract
BACKGROUND Hepatoma upregulated protein (HURP) and Ki-67 have been identified as cancer-related genes involved in cell growth and proliferation. Previous experimental studies have suggested an essential role for HURP expression in liver carcinogenesis. However, data regarding HURP expression in hepatocellular carcinoma (HCC) and its correlation with patient outcomes are limited. In this study, we examined the clinicopathologic features associated with HURP expression in HCC, and compared them to the results of the Ki-67 study. METHODS Eighty-seven resected HCC at tumor, node, metastasis (TNM) stages I (n = 28), II (n = 29), and III (n = 30) were evaluated. HURP and Ki-67 expression were assessed by immunohistochemistry. Multivariate analysis was used to examine the prognostic significance of HURP and Ki-67 expression. RESULTS HURP expression in HCC tissue was observed in 59% of patients and associated with female sex, low white blood cell count, and low platelet count. Ki-67 expression was observed in 67% of patients and associated with younger age, higher serum α-fetoprotein (AFP) levels, and frequent microvascular invasion. Univariate analysis showed that factors related to overall survival were: age >55 years, AFP >20 ng/mL, indocyanine green retention rate at 15 minutes (ICG-15) >15%, tumor size >5 cm, multiple tumors, macrovascular invasion, microvascular invasion, Ki-67 expression, and serum vascular endothelial growth factor >170 pg/mL. HURP expression was not associated with postresection survival. Multivariate analysis indicated that macrovascular invasion, multiple tumors, ICG-15 >15%, and Ki-67 expression were independent factors for overall survival. Multiple tumors and Ki-67 expression were independent factors related to recurrence-free survival. CONCLUSION In our study, HURP expression in HCC tissue was not associated with post-resection survival. Ki-67 expression was an independent prognostic factor for survival. Our results suggest that the effect of HURP activity on growth, invasion, and postresection outcome of HCC in actual patients is less than previously demonstrated in experimental studies.
