AbstractThe regional lymph node-positive bladder cancer was classified as stage IV in the AJCC 7th edition but was changed to stage IIIB in the 8th edition, revised in 2018. Among the various studies involving immune checkpoint inhibitors, groups that had only lymph node metastasis showed better outcomes than those with distant metastasis. Therefore, it is necessary to rethink the treatment strategy for lymph node-positive bladder cancer. The aim of this study was to compare the treatment outcomes of chemotherapy, surgery, and combination therapy in patients with lymph node-positive bladder cancer. From 1 January 2010 to 31 December 2015, patients with bladder cancer presenting local lymph node metastasis at the time of diagnosis were treated with a single treatment strategy, with either radical cystectomy or chemotherapy or with a combined strategy using both. Treatment outcomes were retrospectively analyzed on the basis of clinical indices and survival time. Out of 230 patients with bladder cancer, 44 (19.1%) were treated with palliative chemotherapy, 30 (13.0%) with neoadjuvant chemotherapy followed by cystectomy, 129 (56.1%) with cystectomy followed by adjuvant chemotherapy, and 27 (11.7%) with cystectomy alone. Median survival among all groups was 30.4 months. For each group, median overall survival was 19.3, 49.1, 42.6, and 11.2 months, respectively. This study represents an advancement in understanding the impact of clinical treatment patterns of lymph node-positive bladder cancer through comparison of survival data of patients treated with different therapeutic strategies. Combined treatment resulted in better outcomes than did single treatments.© 2019 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.
