Moreover, PCDHGB7 hypermethylation showed promising potential in identifying sessile UC tumors or cases that might be missed in clinical detection and outperformed standard urine cytology in detecting bladder cancer (82.1% vs. 34.5%), ureter cancer (78.1% vs. 34.4%), and renal pelvis cancer (90.9% vs. 22.7%). This evidence concerns the gene PCDHGB7 and urinary bladder carcinoma.
