The presence of DDR gene alterations, most commonly identified in ERCC2 , showed a trend for better bladder or metastatic recurrence-free survival (HR 0.47, p = 0.070); this finding is in line with studies on neoadjuvant chemotherapy for MIBC [ 48 , 49 ] and systemic chemotherapy for advanced urothelial carcinoma [ 50 ], showing significantly better clinical outcomes for tumors with DDR gene alterations.
