Transcript PHF19-207 as a Potential Biomarker for Colon Cancer Diagnosis and Screening

A recent comprehensive pan-cancer study indicated the high translational potential of the transcript PHF19-207 as a biomarker for colon cancer. This study aimed to analyze the expression of PHF19-207 in colon tissue samples from two different settings to evaluate its clinical utility for diagnosis and screening. Surgical samples of colon tumor and non-tumor tissue were analyzed to determine the diagnostic value of PHF19-207 and its potential correlation with tumor characteristics. Additionally, biopsied samples from individuals undergoing national colorectal cancer screening were examined to assess the potential use of PHF19-207 in early detection. PHF19-207 expression levels were measured in all samples using Real-Time Polymerase Chain Reaction. A statistically significant difference was observed between tumor and non-tumor tissue (p = 0.002) and between tumor tissue and healthy mucosa samples (p < 0.001). Furthermore, polyp samples exhibited significantly higher PHF19-207 expression compared to healthy mucosa (p = 0.035). Receiver operating characteristic (ROC) analysis indicated that PHF19-207 can effectively differentiate malignant from healthy tissue, with an AUC value of 0.9044. Considering the increasing incidence of colorectal cancer in younger populations and the need for improved early detection, PHF19-207 expression could be explored as the basis for a relatively simple and efficient test, enabling a more comprehensive and affordable screening strategy.
