We found no difference in histopathologic features and outcomes between men and women treated with RNU for UTUC. Nevertheless, epidemiologic and mechanistic molecular studies should be encouraged to design, analyze, and report gender-specific associations to aid in our understanding of gender impact on UTUC incidence, progression, and metastasis.

Positive soft tissue surgical margin is a strong predictor of recurrence and eventual death from urothelial carcinoma of the bladder. Soft tissue surgical margin status should always be reported in the pathological reports after radical cystectomy. Due to uniformly poor outcomes patients with positive soft tissue surgical margins should be considered for studies on adjuvant local and/or systemic therapy.

What ' s known on the subject? and What does the study add? It is well established that upper tract urothelial carcinoma is a rare cancer with an aggressive course. Currently, radical nephroureterectomy with bladder cuff excision remains the standard of care in the treatment of these tumours. Previous studies demonstrate that stage, grade and lymphovascular invasion have prognostic signifi cance on recurrence and outcome whereas the prognostic impact of tumour location remains unclear.

rates of the different tumour grades (mean follow-up was 57 months). RESULTSAccording to the 1973 WHO classification, none of the pT1 BC specimens were graded as G1, while 36% were graded as G2 and 64% were graded as G3. Histological reassessment according to the 2004 WHO classification highlighted only 4% low-grade and 96% high-grade tumours. The 10-year cancer-specific survival rates of high-grade tumours (85%) were intermediate between G2 (96%) and G3 (78%). CONCLUSIONSThe results of the present study support the presumption that the 1973 WHO classification is more suitable for predicting outcome for pT1 tumours, by defining at least two prognostic groups. A new classification should revise the definition of low-and high-grade pT1 BC to preserve the prognostic value of tumour grading.

BackgroundA multicentre study was conducted to investigate the impact of sarcopenia as an independent predictor of oncological outcome after radical cystectomy for bladder cancer.MethodsIn total, 500 patients with available digital computed tomography scans of the abdomen obtained within 90 days before surgery were identified. The lumbar skeletal muscle index was measured using pre‐operative computed tomography. Cancer‐specific survival (CSS) and overall survival (OS) were estimated using Kaplan–Meier curves. Predictors of CSS and OS were analysed by univariable and multivariable Cox regression models.ResultsBased on skeletal muscle index, 189 patients (37.8%) were classified as sarcopenic. Patients with sarcopenia were older compared with their counterparts (P = 0.002), but both groups were comparable regarding to gender, comorbidity, tumor, node, metastasis (TNM) stage, and type of urinary diversion (all P > 0.05). In total, 234 (46.8%) patients died, and of these, 145 (29.0%) died because of urothelial carcinoma of the bladder. Sarcopenic patients had significantly worse 5 year OS (38.3% vs. 50.5%; P = 0.002) and 5 year CSS (49.5% vs. 62.3%; P = 0.016) rates compared with patients without sarcopenia. Moreover, sarcopenia was associated independently with both increased all‐cause mortality (hazard ratio, 1.43; 95% confidence interval 1.09–1.87; P = 0.01) and increased cancer‐specific mortality (hazard ratio, 1.42; 95% confidence interval, 1.00–2.02; P = 0.048). Our results are limited by the lack of prospective frailty assessment.ConclusionsSarcopenia has been shown to be an independent predictor for OS and CSS in a large multicentre study with patients undergoing radical cystectomy for bladder cancer.
