Lymphovascular invasion (LVI) predicts poor survival in patients with pathologically localized or locally advanced upper urinary tract urothelial carcinoma (UT-UC). However, LVI is associated with high tumor grade, tumor necrosis, advanced tumor stage, tumor location, concomitant carcinoma in situ, lymph node metastasis, and sessile tumor architecture. These factors might interfere with the analysis of the impact of LVI on oncological prognosis.

- This study investigates how the location of tumors (renal pelvis vs. ureter) affects cancer outcomes for patients with upper tract urothelial carcinoma (UTUC) who underwent radical surgery between 2005 and 2019.
- A total of 302 patients were analyzed, focusing on outcomes like recurrence and survival rates, with findings indicating that ureteral tumors correlated with worse rates of local recurrence.
- The research concludes that tumor location is a significant factor in prognosis for UTUC, suggesting the need for further studies to explore underlying biological reasons for these disparities.
Objectives: To carry out a comparison of upper urinary tract urothelial carcinoma characteristics and behavior between patients in Taiwan and Japan.
Methods: A Taiwan urinary tract urothelial carcinoma cohort was obtained from Kaohsiung Chang Gung Memorial Hospital, and a Japan urinary tract urothelial carcinoma cohort from Hirosaki University Hospital. The inclusion criteria were urinary tract urothelial carcinoma patients who underwent radical nephroureterectomy.
Purpose: Pure ureter cancers are rare and account for only 1-3 % of urothelial carcinomas with limited data. Nowadays, nephron-sparing methods are reserved mainly for imperative cases. This study intends to assess the oncologic outcome between segmental ureterectomy (SU) and radical nephroureterectomy (RNU) for pure ureteral urothelial carcinoma.

Purpose: The prevalence of urothelial carcinoma is high in dialysis patients. Radical cystectomy is an invasive procedure for patients with recurrent, multiple, or invasive bladder cancer. However, the prognosis of radical cystectomy in dialysis patients has rarely been reported.
