This study investigated the association between CD133 expression in cancer cells and the clinical outcome of non-mucin producing intrahepatic cholangiocarcinoma (ICC). Methods: Fifty-seven non-mucin producing ICC patients were enrolled in this study. Immunohistochemistry (IHC) and immunofluorescence staining for CD133 as well as other cancer-associated proteins, including cytokeratin 19, TGF-β1, p-Smad2 and epithelial–mesenchymal transition (EMT) markers S100A4, E-Cadherin and Vimentin were analyzed. Results: IHC staining showed that tumor cells in 52.6% of patients expressed CD133. The CD133+ patients had significantly higher metastasis rate than those without CD133+ tumor cells (36.7% vs. 10.1%, p = 0.03). The CD133+ patients had shorter overall and disease-free survival time as compared to the CD133− patients. Furthermore, 90.9% of CD133+ patients developed cancer recurrence, as compared to 64.3% of CD133− patients (p = 0.02). As compared to CD133− patients, tumor cells in CD133+ patients demonstrated high levels of TGF-β/p-Smad2 as well as EMT-like alteration, characterized by loss of E-Cadherin and expression of Vimentin and S100A4. Conclusions: CD133 expression in ICC tumor cells indicates poor prognosis of the disease and might be associated with TGF-β related EMT alterations. date: 2018 publisher: BioMed Central id_scheme: DOI ppn_swb: 1655275488 own_urn: urn:nbn:de:bsz:16-heidok-243166 language: eng bibsort: CAIXIAOBOCD133EXPRE2018 full_text_status: public publication: Journal of Translational Medicine volume: 16 number: 50 place_of_pub: London pagerange: 1-7 issn: 1479-5876 citation: Cai, Xiaobo ; Li, Jun ; Yuan, Xiaodong ; Xiao, Jingbo ; Dooley, Steven ; Wan, Xinjian ; Weng, Honglei ; Lu, Lungen (2018) CD133 expression in cancer cells predicts poor prognosis of non-mucin producing intrahepatic cholangiocarcinoma.
