ABSTRACT
INTRODUCTION:
The prognostic role of prior history of bladder cancer (BCa) among patients treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) is poorly addressed. We aimed to investigate the role of prior BCa on any recurrence, distant metastases, and bladder recurrence following RNU among low-grade (LG) and high-grade (HG) UTUC patients. PATIENTS ANDMETHODS:
We retrospectively analyzed 1,580 UTUC patients treated with RNU at 8 tertiary referral centers between 1992 and 2016. Any recurrence was defined as recurrence in the urinary tract, in the resection bed, or distant metastases (defined as disease outside the urinary tract and regional lymph nodes). Time to recurrence was computed from RNU. Multivariable Cox models were generated to predict risk of any recurrence, distant metastases, and bladder recurrence according to prior BCa history, coded as no prior BCa, non-muscle-invasive (NMIBC), and muscle-invasive BCa (MIBC).RESULTS:
Median follow-up for survivors was 4 years. Overall, 71%, 25%, and 4% of patients had no prior BCa, NMIBC and MIBC. 5-year any recurrence-free survival was 61%, 41%, and 19% in LG (P < .001) and 42%, 34%, and 30% in HG patients (P = .1) with no prior BCa, NMIBC, and MIBC. On multivariable models, LG patients with NMIBC and MIBC showed a significantly higher risk of any recurrence compared to no prior BCa (both p≤0.005); previous NMIBC was associated with any recurrence among HG patients (P = 0.04). 5-year distant metastases-free survival was 92%, 90%, and 87% in LG (P > .05) and 68%, 75%, and 45% in HG patients (P = .01) with no prior BCa, NMIBC, and MIBC. Previous NMIBC increased the risk of bladder recurrence among LG (P < .001) and HG (P = .003) patients.CONCLUSIONS:
UTUC patients with prior history of BCa exhibit a higher risk of any recurrence after RNU. Our study provides important information which could address patient's counseling and decision-making process.Palavras-chave
