Fig. 1From: Integrative analyses identify CD73 as a prognostic biomarker and immunotherapeutic target in intrahepatic cholangiocarcinomaExpression pattern and prognostic value of CD73 in ICC. A Representative images of CD73 expression within ICC tumor samples. B Pie chart showing CD73 was elevated in 42.62 and 43.63% of cases in the FU-iCCA cohort and ZSH cohort, respectively. High CD73 mRNA (C) or CD73 protein (D) expression was significantly associated with poor OS in the FU-iCCA cohort. Kaplan–Meier survival curves for OS (E) and RFS (F) of 259 ICC patients after curative resection according to CD73 expression level in the ZSH cohort. ICC, intrahepatic cholangiocarcinoma; ZSH cohort, Zhongshan Hospital cohort; OS, overall survival; RFS, recurrence-free survivalBack to article page
