Relationship between the number of lymph nodes dissected and prognosis in muscle‐invasive bladder cancer in the era of neoadjuvant chemotherapy

Many studies have shown a good prognostic association with a large number of lymph node dissections. However, most of these studies did not include patients who have received neoadjuvant chemotherapy. The purpose of this study was to verify the relationship between survival outcomes and the number of lymph nodes removed during radical cystectomy in patients with muscle‐invasive bladder cancer in the era of neoadjuvant chemotherapy.
