Urinary Tract Urothelial Carcinoma

Background: Upper urinary tract urothelial carcinoma (UTUC) is the most common malignancy occurring after kidney transplantation (KT) in Taiwan. The aim of this study was to investigate the association between native kidney hydronephrosis and UTUC in post-KT patients. Methods: From 2003 to 2018, we conducted a retrospective cohort study that enrolled 1005 post-KT patients, 67 of whom were subsequently diagnosed with UTUC. We divided patients into two groups based on whether or not they had UTUC. Multivariate analysis and Kaplan-Meier plot were used to evaluate if native kidney hydronephrosis was associated with post-KT UTUC. Results: The total cohort consisted of 612 men (60.9%) and 393 women (39.1%) with a mean age of 48.2 ± 12.0 at KT. The mean follow-up time was 118.6 ± 70.2 months, and mean time from KT to UTUC was 7.53 years. There was a significant gender difference with a female predominance among the UTUC patients (73.1% versus 26.9%, p < 0.001). Native kidney hydronephrosis occurred more frequently in the UTUC group (68.7% versus 4.8%, p < 0.001). Multivariate analysis showed that native kidney hydronephrosis and female gender were significantly associated with UTUC with odds ratios of 35.32 (95% CI, 17.99–69.36; p < 0.001) and 3.37 (95% CI, 1.55–7.29; p = 0.002), respectively. UTUC in the post-KT patients also showed aggressive pathological characteristics and a tendency toward bilateral lesions (41.8%). Conclusions: Native kidney hydronephrosis is significantly associated with post-KT UTUC patients in Taiwan. Native kidney hydronephrosis may be a deciding factor for standard nephroureterectomy and bladder cuff excision in selected patients. Nevertheless, almost half of the patients with kidney hydronephrosis do not present with UTUC at the end of our study.

Urinary Tract Urothelial Carcinoma

Urothelial carcinoma is the most common cancer following kidney transplantation (KT) in Taiwan. Unusual presentation of upper urinary tract urothelial carcinoma (UTUC) is noted in Taiwan and China. As the post-KT-UTUC oncological course is not fully understood, the aim of this study is to identify postulated significant differences for the clinical cancer course of UTUC among end-stage renal disease (ESRD) patients with and without KT. From 2005 January to 2016 March, 194 ESRD patients underwent radical nephroureterectomy due to UTUC in our hospital. The parameters were obtained from the chart record and pathology report. SPSS version 21 software was used for all statistical analyses. Unequal matching created study groups wherein a 0.2 caliper width was performed for adjusting these confounding pathological factors. Propensity score-matching cohort was performed for each population first, and then for all the study patients. We observed that the average age of UTUC in ESRD patients after KT was younger than in those without KT. The pathological factors such as stage, bladder cancer history, papillary structure, lymphovascular invasion, and variant histology were equal in these two groups. However, younger onset (p<0.001), more multifocal tumors, and carcinomas in situ were observed in post-KT UTUC (p<0.001 and 0.006, respectively). After adjustment of pathological factors by propensity score-matched analysis, the 5-year systemic UTUC recurrence was significantly more in ESRD after KT compared with ESRD without KT (p=0.03). No obvious difference in 5-year cancer related death could be observed between these two groups (p=0.314). Post-kidney transplantation upper urinary tract urothelial carcinoma in Taiwan is relatively common, has younger onset, and is associated with aggressive pathological features. The oncologic outcome of UTUC after KT is poor in our observation, even after propensity scored-matched analysis. It indicates the immunosuppression status is still associated with more malignant UTUC behavior.

AbstractThis study aims to compare oncologic and functional outcomes after radical nephroureterectomy (RNU) and segmental ureterectomy (SU) in patients with upper urinary tract urothelial carcinoma (UTUC). We retrospectively collected data on patients who underwent either RNU or SU of UTUC. Propensity score matching was performed among 394 cases to yield a final cohort of 40 RNU and 40 SU cases. Kaplan–Meier analysis and the log-rank test were used to compare overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), and intravesical recurrence-free survival (IVRFS) between the groups. We also compared the change in postoperative estimated glomerular filtration rate (eGFR). There was no significant difference in terms of CSS, PFS, and IVRFS between the RNU and SU groups, but the RNU group had a better OS than the SU group (p = 0.032). Postoperative eGFR was better preserved in the SU group than in the RNU group (p < 0.001). SU provides comparable CSS, PFS, and IVRFS for patients with UTUC compared to RNU, even in patients with advanced-stage and/or high-grade cancer. Further, SU achieves better preservation of renal function.

Urinary Tract Urothelial Carcinoma

IntroductionThe treatment standard for high-risk upper urinary tract urothelial carcinoma (UUTUC) is radical nephroureterectomy. However, some patients may be unfit or unwilling, and in such patients the available alternatives are suboptimal. Therapies targeting the programmed death (PD) pathway have shown promise in urothelial carcinom (UC). We designed the current study to determine the safety and efficacy of administering MK-3475 (a monoclonal antibody targeting interaction between PD-1 and its ligand) in combination with bacillus Calmette-Guerin (BCG) in high-risk non-muscle invasive UUTUC patients.MethodsThis represents a single-centre phase-II efficacy study of MK-3475 therapy in combination with BCG for subjects, 18 years of age or older, with pathologically documented non-muscle invasive high-risk UUTUC unfit or unwilling to be treated with radical nephroureterectomy. Twenty subjects will be enrolled; patients will receive treatment with 200 mg of MK-3475 every 21 days, starting 2 weeks from the initial endoscopic resection and continuing for 6 weeks after the final dose of BCG. The primary objective is to determine the safety and efficacy of administering MK-3475 at a fixed dose of 200 mg every 3 weeks in conjunction with intrapelvic BCG. Secondary objectives include 19 week and the 3, 12 and 24-month post-treatment completion complete response and progression-free rate assessments.Ethics and disseminationThe study has been approved by the Institutional Review Board of the Henry Ford Hospital. The results of this study will be published in a peer-reviewed journal and presented at a scientific conference.Trial registration numberNCT03345134
