Purpose: It has been shown that there are some difference of the distribution of the upper urinary tract cancer between Taiwanese and other races. Previous studies have shown an increased risk of upper urinary tract urothelial carcinoma. We try to re-examine this risk.
Materials and Methods: We enrolled all 93 patients of upper urinary tract cancer in Show-Chaun hospital in Chang-Hua Taiwan during 2008-2015, and we retrospectively followed the development of cancer until 2012 by analysis of data collected from the Taiwan Cancer Registry.
Results: There were 93 newly diagnosed cases of upper urological cancer and most of them were transitional cell carcinoma (70.1%) and renal cell carcinoma(28.0%). The mean age at diagnosis for upper urinary tract cancer was 65.5 years. Focusing on urothelial carcinoma, when stratified by location, there are 45.2% in renal pelvis, 32.6% in upper ureter and 20.4% in both. About the tumor stage, there are 28.3% patients was stage I, 19.8% was stage II, 35.0% was stage III and 16.9% was stage IV. The crude death rate during 2008 to 2015 was 9.31% in stage I, 7.23% in stage II, 30.4% in stage III and 66.7% in stage IV, respectively.
Conclusions: The urothelial carcinoma consisted the majority of upper urinary tract cancer in Taiwan, followed by renal cell carcinoma. Most of the urothelial carcinoma was located in the renal pelvis. It makes the diagnosis more challengeable.
