Abstract
INTRODUCTION: We report a case in which enfortumab vedotin (EV) therapy was administered as a third-line treatment for locally advanced bladder cancer (bc), enabling successful radical resection. CASE PRESENTATION: This report describes the case of a 69-year-old male patient with locally advanced bc and pelvic lymph node (LN) metastases. After the failure of first-line chemotherapy and second-line immunotherapy, the patient received EV as third-line treatment. EV therapy resulted in significant tumor reduction, enabling successful radical cystectomy and lymph node dissection (LND). The patient remained recurrence-free for 22 months post-surgery. CONCLUSION: EV therapy suggests that it is a promising avenue for further exploration, potentially redefining the therapeutic landscape of historically challenging cases.
