Adenomatous Polyposis Coli (APC) Promoter Gene Methylation in Urine-Derived DNA: A Non-invasive Biomarker for Early Bladder Cancer Detection and Tumor Aggressiveness.

Background Bladder urothelial carcinoma (BLCA) is a major cause of morbidity and mortality worldwide, largely due to the high frequency of disease relapse and the lack of efficient endoscopic diagnostic methods. This study aimed to address this clinical gap by evaluating the potential of using adenomatous polyposis coli (APC) gene promoter methylation as a biomarker detectable in urine DNA of individuals with BLCA. Methods Methylation-specific PCR was used to determine the methylation status of the APC promoter gene in 50 bladder carcinoma patients and 50 apparently healthy individuals.

Comparative Study Analysis of Epstein-Barr Virus Infection: Tissue Versus Blood Samples in Patients With Prostatic Adenocarcinoma and Its Correlation With Clinicopathological Parameters.

Prostate cancer (PCa) is the most frequently diagnosed cancer and a leading cause of cancer-related mortality in men. The diagnosis and treatment of PCa carry considerable medical, psychological, and economic implications. Among the risk factors contributing to cancer, viral infections, notably Epstein-Barr virus (EBV), play a significant role.
