|a We retrospectively reviewed 67 patients who presented with metastatic urothelial carcinoma to the Department of Urology, Asahikawa Medical University Hospital between 2000 and 2013. Furthermore, 13 patients with comparatively longer survival (2 years or longer after diagnosis) were analyzed to find any clinical characteristics among these patients. The primary site was the upper tract in 41 patients and bladder in 26. The most frequent metastatic site was regional lymph nodes (49 patients), followed by viscera (36 patients) and distant lymph nodes (17 patients). Primary tumor resections were performed on 83% of the patients with only regional lymph node metastasis, but on only 35% of the patients with distant metastasis. Median overall survival (OS) of patients was 8.5 months in this series. Median OS of patients with only regional lymph node metastasis was 15 months, which was significantly longer than that (8 months) of patients with distant metastasis. Multivariate analysis revealed only regional lymph node metastasis and the number of metastatic sites were significant prognostic factors for OS. We further investigated the clinical characteristics of 13 patients with comparatively longer survival. Other than a small number of metastatic sites (1 or 2) and no distant lymph node metastasis, we could not find any significant characteristics to predict longer prognosis. The present study showed that primary tumor resection did not have a significant benefit on survival in patients with metastatic urothelial carcinoma at initial presentation. However, primary tumor resection should be considered when there is only regional lymph node metastasis and few metastatic sites
