Clinical Trial Summary

This clinical trial is designed to evaluate the efficacy of single immediate intravesical chemotherapy instillation in the prevention of bladder recurrence after diagnostic ureteroscopy for upper tract urothelial carcinoma (UTUC) patients.


Description:

INTRODUCTION

Upper tract urothelial carcinomas (UTUC) are relatively uncommon compared to bladder cancer and account for only 5-10% of urothelial carcinomas [Munoz et al., 2000; Siegel et al., 2012; RouprĂȘt et al. 2015], with an estimated annual incidence in Western countries of ~2 cases per 100,000 inhabitants. In 17% of cases, concurrent bladder cancer is present [Cosentino et al., 2013].

Urinary cytology, cystoscopy and computed tomograpy urography should be performed as the standard diagnostic work-up with the grade A of recommendation [RouprĂȘt et al., 2015]. Diagnostic ureteroscopy and biopsy should be performed, certainly in cases where additional information will impact treatment decisions. Such ureteroscopic biopsies can determine tumour grade in 90% of cases with a low false-negative rate [Rojas et al., 2012]. Ureteroscopy can prove invaluable in cases of suspected UTUC, especially when the diagnosis is equivocal, or if nephron sparing surgery is considered. However, it can pose potential hindrances, including difficulty in obtaining adequate tissue, inconsistent pathologic interpretation and prediction, and a high rate of upgrading and upstaging at the time of nephroureterectomy [Potretzke et al., 2015].

Recurrence in the bladder after management of UTUC occurs in 22-47% of UTUC patients [Xylinas et al., 2012; Zigeuner et al., 2006; Novara et al., 2008], compared with 2-6% in the contralateral upper tract [Li et al., 2010; Novara et al., 2009]. At our institution, we reported that 30.8% of UTUC patients developed intravesical recurrence, which was in line with the global trend [Fang et al., 2013]. Although the risk factors for development of bladder tumor post surgical management of UTUC were previously studied, considerable variations were observed in the literature. In previously published studies, we pointed out that lower tumor grade, tumor multifocality, concomitant carcinoma in situ (CIS), tumors located in the lower ureter, ureteroscopy history and unmethylated promoter of GDF15 and RASSF1A promoters were considered as predictors to develop bladder recurrence after surgery by univariate and multivariate analysis [Fang et al., 2013, Xiong et al., 2015]. As an effective tool to evaluate UTUCs visually or by biopsy, ureteroscopy was selectively used in early UTUC patients without atypical radiography. It was our hypothesis that retrograde flow, increased urine flow rate and intraluminal pressure might lead to the shedding of tumor cells (intraluminal tumor seeding is thought to contribute to intravesical recurrence after nephroureterectomy), which implant in the bladder to develop recurrences [Xiong et al., 2015].

AIM OF THE WORK This clinical trial is designed to evaluate the efficacy of single immediate intravesical chemotherapy instillation in the prevention of bladder recurrence after diagnostic ureteroscopy for UTUCs.
