Application of PLK1 and HOXA13 Gene Expression Levels in Urine in the Diagnosis of Non-muscle Invasive Bladder Cancer

This study aimed to develop an accurate and non-invasive urine-based gene expression assay, including fibroblast growth factor receptor 3 (FGFR3), homeobox A13 (HOXA13), and polo-like kinase 1 (PLK1), to diagnose non-muscle-invasive bladder cancer (NMIBC) at stages Ta and T1. The samples were acquired from 62 patients with NMIBC, 31 control individuals, and 31 patients with non-cancerous genitourinary tract diseases. The expression levels of three relevant genes were determined using quantitative RT-PCR. In addition, the sensitivity and specificity of the data for these genes were computed. Our results showed that PLK1, HOXA13, and FGFR3 expressions of genes were significantly elevated in patients compared to the control groups (p = 0.0001; p = 0.039). The sensitivity and specificity for the FGFR3 gene were 55% and 76%, respectively (p = 0.39). These parameters for HOXA13 were 100% and 93% (p = 0.0001) and for PLK1 were 100% and 86% (p = 0.0001) for diagnosing and monitoring NMIBC. HOXA13 and PLK 1 exhibited adequate specificity and sensitivity for diagnosis. The results of this research showed that despite the higher expression of these genes in urine, only HOXA13 and PLK1 had sufficient and proper specificity and sensitivity, so the urinary expression of these two genes can be used in future studies for diagnosis and monitoring in cancer bladder.PMID:38713442 | DOI:10.1007/s10528-024-10735-3
