Combined cancer testis antigens enhanced prediction accuracy for prognosis of patients with hepatocellular carcinoma. Int J Clin Exp Pathol. 2015;8(4):3513-28 Authors: Wang M, Li J, Wang L, Chen X, Zhang Z, Yue D, Ping Y, Shi X, Huang L, Zhang T, Yang L, Zhao Y, Ma X, Li D, Fan Z, Zhao L, Tang Z, Zhai W, Zhang B, Zhang Y Abstract Cancer testis antigens (CTAs) are selectively expressed in malignant cells and can serve as ideal targets for immunotherapy. We investigated the expressions of MAGE-A3, MAGE-A4, MAGE-C2 and NY-ESO-1 to determine if combinatorial expressions of CTAs might be as potential prognostic markers for patients with hepatocellular carcinoma (HCC). In tumor tissues of 142 HCC patients, the mRNA expressions of MAGE-A3, MAGE-A4, MAGE-C2 and NY-ESO-1 were 78.9%, 33.8%, 74.6% and 14.1% respectively. Furthermore, the expressions of MAGE-A3, MAGE-A4 and combination of MAGE-A3, MAGE-A4 and NY-ESO-1 (CTAs-A3/A4/NY) showed positive correlations with serum AFP, tumor stages and Ki-67 (P < 0.05). In addition, mRNA expressions of CTAs were significantly consistent with protein expressions of CTAs by immunohistochemistry (P > 0.05). Receiver operating characteristic curves (ROC) analysis showed that CTAs-A3/A4/NY had larger areas under ROC curve (0.768), specificity (99.1%), Youden's index (44.6), positive predictive value (90.9%) and negative predictive value (89.9%) for predicting HCC recurrence than other CTAs. Moreover, t...
