Overall survival and disease-free survival of IHCC patients classified by histological type. a Overall survival curves of IHCC patients. The survival of patients in the p-Group P was better than that of those in both the p-Group H and the p-Group U (p = 0.098, p < 0.05, respectively). b Disease-free survival curves of IHCC patients. The survival of patients in the p-Group P was significantly better than that of those in both the p-Group H and the p-Group U (p < 0.05). IHCC: intrahepatic cholangiocarcinoma, p-Group P: SSTR2 negative and Bcl2 positive, p-Group H: SSTR2 positive and Bcl2 negative, p-Group U: SSTR2 positive and Bcl2 positive or SSTR2 negative and Bcl2 negative
