Association Between the Number of Dissected Lymph Nodes During Pelvic Lymphadenectomy and Cancer-Specific Survival in Patients with Lymph Node–Negative Urothelial Carcinoma of the Bladder Undergoing Radical Cystectomy

摘要

Background A larger number of dissected lymph nodes (LN) during pelvic lymphadenectomy in patients with muscle-invasive transitional-cell carcinoma of the bladder treated by radical cystectomy (RC) is crucial for exact tumor staging and is associated with a positive oncological outcome.
