Upper urinary tract urothelial carcinoma behaviors in patients with end-stage renal disease after kidney transplantation in Taiwan

To determine upper urinary tract urothelial carcinoma (UT-UC) behavior in patients with end-stage renal disease (ESRD) after kidney transplantation (KT).

From 2005 to 2012, 117 ESRD patients with localized UT-UC underwent nephroureterectomy at our institution. We divide these patients into two groups according to having had KT or not. Kaplan-Meier survival plot and multivariate analysis were used to evaluate whether kidney transplantation interfered with the UT-UC outcome.

The mean age was younger in ESRD with KT group (p = 0.001), but there was no difference in gender, smoking, or previous bladder cancer history between these two groups. The pathological features were more aggressive in ESRD with KT group compared to those without KT in regard to incidence of carcinoma in situ (p = 0.025) and multifocality (p = 0.001). Kidney transplantation did not interfere with the oncological outcome of UT-UC in ESRD patients. There were no differences in oncological outcome. Five-year metastasis-free survival rate was comparable.

In our sample, for patients with ESRD after kidney transplantation, the postoperative onset of UT-UC was younger and the pathological features were more aggressive. Standard surgical intervention resulted in satisfactory and similar outcome as did ESRD.
