Ureteral and multifocal tumours had a worse prognosis than renal pelvic tumours. These findings are not in line with recently published data and should be investigated in a prospective assessment to obtain a definitive statement regarding this matter.
Despite the increased time to radical surgery, diagnostic ureteroscopy can be systematically performed for the appraisal of UTUC to refine the therapeutic strategy without significantly affecting oncological outcomes, even for MI lesions.
In the current study, intravesical recurrence occurred in 35 % of patients with UTUC after RNU. Previous history of bladder cancer, tumor multifocality, concomitant CIS and laparoscopic approach were independent predictors of intravesical recurrence. These findings are in line with recent published data and should be considered carefully to provide a definitive surveillance protocol regarding management of urothelial carcinomas regardless of the location of urothelial carcinomas in the whole urinary tract.
LNS is helpful for survival stratification in patients treated with RNU for UTUC. However, LNS did not appear as an independent predictor of survival in this retrospective series and needs to be investigated in a large multicentre, prospective evaluation.
Study Type – Prognosis (cohort)Level of Evidence 2bWhat's known on the subject? and What does the study add?Upper urinary tract urothelial carcinoma (UUT‐UC) is a rare disease, usually treated by nephroureterectomy, occurring in a population with a median age of 70 years and with frequent tobacco use and other comorbidities. We know that the American Society of Anesthesiologists (ASA) score has prognostic value in urological oncology but this has not been assessed in UUT‐UC.Using a multi‐institutional French database, we have shown that the 5‐year cancer‐specific survival differed significantly between ASA 1, ASA 2 and ASA 3 patients (83.8%, 76.9% and 70.6%, respectively; P= 0.01). ASA status had a significant impact on cancer‐specific survival in univariate and multivariate analyses, with a threefold higher risk of mortality at 5 years for ASA 3 compared with ASA 1 patients (P= 0.04).OBJECTIVE
To evaluate the impact of American Society of Anesthesiologists (ASA) scores on the survival of patients treated with radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UUT‐UC).
PATIENTS AND METHODS
A retrospective multi‐institutional cohort study of the French collaborative national database of UUT‐UC treated by RNU in 20 centres from 1995 to 2010.
The influence of age, gender and ASA score on survival was assessed using a univariable and multivariable Cox regression analysis with pathological features used as covariables.
RESULTS
Overall, 554 patients were included. The median follow‐up was 26 months (10–48 months), and the median age was 69.5 years (61–76 years). In total, 114 (20.6%) patients were classified as ASA 1, 326 (58.8%) as ASA 2 and 114 (20.6%) as ASA 3.
The 5‐year recurrence‐free survival (P= 0.21) and metastasis‐free survival (P= 0.22) were not significantly different between ASA 1 (52.8% and 76%), ASA 2 (51.9% and 75.3%) and ASA 3 patients (44.1% and 68.2%, respectively).
The 5‐year cancer‐specific survival differed significantly between ASA 1, ASA 2 and ASA 3 patients (83.8%, 76.9% and 70.6%, respectively; P= 0.01).
ASA status had a significant impact on cancer‐specific survival in univariate and multivariate analyses, with a threefold higher risk of mortality at 5 years for ASA 3 compared with ASA 1 patients (P= 0.04).
CONCLUSIONS
ASA classification correlates significantly with cancer‐specific survival after RNU for UUT‐UC.
It is a further pre‐operative clinical variable that can be incorporated into future risk prediction tools for UUT‐UC to improve their accuracy.
