Popis výsledku v původním jazyce

Background and Aims. Genetic and epigenetic alterations play an important role in urothelial cancer pathogenesis. Deeper understanding of these processes could help us achieve better diagnosis and management of this life-threatening disease. The aim of this research was to evaluate the methylation status of selected tumor suppressor genes for predicting BCG response in patients with high grade non-muscle-invasive bladder tumor (NMIBC). Materials and Methods. We retrospectively evaluated 82 patients with high grade non-muscle-invasive bladder tumor (stage Ta, T1, CIS) who had undergone BCG instillation therapy. We compared epigenetic methylation status in BCG-responsive and BCG-failure groups. We used the MS-MLPA (Methylation-Specific Multiplex Ligation-Dependent Probe Amplification probe sets ME001 and ME004. The control group was 13 specimens of normal urotel (bladder tissue)). Results. Newly identified methylations in high grade NMIBC were found in MUS81a, NTRK1 and PCCA. The methylation status of CDKN2B (P=0.00312(star star)) and MUS81a (P=0.0191(star)) is associated with clinical outcomes of BCG instillation therapy response. CDKN2B and MUS81a unmethylation was found in BCG failure patients. Conclusion. The results show that the methylation status of selected tumor suppressor genes (TSGs) has the potential for predicting BCG response in patients with NMIBC high grade tumors. Tumor suppressor genes such as CDKN2b, MUS81a, PFM-1, MSH6 and THBS1 are very promising for future research.
