    AbstractCholangiocarcinoma (CCA) is a common and lethal malignant tumor originating from bile duct epithelial cells. Various tumor biomarkers have been used for its clinical screening, such as carbohydrate antigen 19-9 and carcinoembryonic antigen. This study aimed to demonstrate the value of associated genes-CMT1A duplicated region transcript 15 (CDRT15) for prognosis of CCA by integrated bioinformatics analysis. We obtained CDRT15 expression data and clinical information on patients with CCA from The Cancer Genome Atlas database. Then, we processed the data by differentially expressed gene analysis, gene set enrichment analysis, statistical analysis, etc. Gene Ontology enrichment analysis was aimed to explore the function of gene-related proteins. Single-sample gene set enrichment analysis was used to analyze the correlation between CDRT15 and immune cells. Finally, we constructed the nomogram to predict the prognosis of patients with CCA. The analysis of data in The Cancer Genome Atlas database revealed that CDRT15 was overexpressed in CCA tissues. We performed the interrelation analysis of immune infiltration, showing that CDRT15 are mainly associated with the immune/inflammatory response. ROC curve showed that CDRT15 can be a diagnostic marker of CCA. Subsequently, the prognostic analysis showed that the high expression of CDRT15 was correlated with the poor OS, and patients with high CDRT15 expression may have a poor prognosis. CDRT15 is more highly expressed in CCA, thus we identified that CDRT15 could be an efficient biomarker for patients. CDRT15 expression was negatively correlated with prognosis of CCA. CDRT15 may be involved in the immune infiltration process of CCA.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
