ObjectiveTo overview the various molecular biological index to judge the prognosis of intrahepatic cholangiocarcinoma (ICC), in order to promote ICC patients follow-up treatment, improve survival rate, and quality of life of the patients. Methods"ICC" and "prognostic factor" were searched as key words by PubMed and CNKI series full-text database retrieval systems from 2000 to 2015. Totally 48 English papers and 15 Chinese papers were obtained. Choice criteria:the molecular biological index that affect the prognosis of ICC patients, and can effectively guide treatment. According to the choice criteria, 45 papers were finally analyzed. ResultsThe indicators of Homer1, mucin 1 (MUC1)\mucin 4 (MUC4), lactate dehydrogenase A (LDH-A), Beclin1, Smad4, protein tyrosine kinase-7 (PTK7), IMP3, cytokeratin 7 (CK7)/cytokeratin 20 (CK20), and sphingosine kinase 1 (SPHK1) could be used as prognostic factors in the survival of patients with ICC, and to determine tumor size and stage, vascular invasion, nerve injury, and lymph node metastasis, are of great clinical significance. ConclusionThese indicators have a significant meanning in the prognosis of ICC and the adjustment of the follow-up treatment.
