Results: We found that HbF1st week (15.3 ± 3.4 vs. 12.6 ± 3.5 g/dL, p < 0.001), HbF14–21–28 DOL, (9.3 ± 3.2 vs. 7.6 ± 3.6 g/dL, p = 0.018), and Hb–34–36 weeks (7.5 ± 3.6 vs. 5.7 ± 3.6 g/dL, p = 0.014) levels were higher in the UCM than in the ICC group. This evidence concerns the gene GSTM1 and intrahepatic cholangiocarcinoma.
