Abstract
Cystic fibrosis (CF) and cystic fibrosis transmembrane conductance regulator (CFTR) mutations have been shown to be associated with the risk of a variety of cancers. However, the clinical significance of aberrant CFTR gene expression in human tumors remains unknown. The expression profiles and prognostic landscapes of CFTR in human cancers were identified from the PubMed, OVID, CNKI, TCGA, ONCOMINE, PrognoScan, and GEPIA databases. Over 11, 000 cancer samples from the literature, GEPIA database, and PrognoScan database were included in this study. In general, CFTR has various expression and prognostic profiles in cancers, but the results from cross-database and meta-analyses revealed that CFTR is a robust biomarker for LUAD prognosis. Collectively, this study suggests that CFTR is an important prognostic biomarker for LUAD survival, implying that it could be used as a prognostic biomarker and therapeutic target for LUAD.
