MFAP5 and intrahepatic cholangiocarcinoma: As shown in Table 2, MFAP5 level in higher ICC TNM stages were higher than those in low ICC TNM stages (Sample numbers of stages I, II, III, IV were 71, 51, 43, 43; P = 0.0141; Fig. 2f), indicating a correlation between MFAP5 expression and ICC TNM stages.
