Risk stratification of metastatic recurrence in invasive upper urinary tract carcinoma after radical nephroureterectomy without lymphadenectomy.

PURPOSE: To assess the risk factors of metastasis relapse in pT2-3 upper tract urothelial carcinomas (UTUCs) treated by radical nephroureterectomy (RNU) without lymphadenectomy (LN). METHODS: A multicentric retrospective study was performed for pT2-3 pNx UTUCs treated by RNU between 1995 and 2010. The following criteria were retrieved: age, gender, American Society of Anaesthesiologists physical status, surgical approach, preoperative hydronephrosis, stage, grade, tumor location, surgical margin, lymphovascular invasion (LVI) status and outcomes. Metastasis-free survival (MFS) was measured by Kaplan-Meier method with the log-rank test. RESULTS: Overall, 151 patients were included. The median follow-up was 18.5 months (IQR 9.5-37.9). The 2- and 5-year MFS were 69 % ± 4.5 and 54.1 % ± 5.8, respectively. In univariate analysis, ureteral location, pT3 stage, positive LVI status and positive surgical margin were significantly associated with worse MFS (p = 0.03; 0.02; 0.01 and 0.006, respectively). In the multivariate analysis of ureteral location and pT3 stage were independent prognostic factors (p = 0.03 and 0.03, respectively). Based on the results of the univariate analysis, we proposed a risk model predicting MFS, which classifies patients into 3 categories with different overall survival (p < 0.001). CONCLUSION: In view of our data, tumor location, T stage, LVI and surgical margin status are mandatory to predict survival in case of RN without LN. Contingent upon external validation, our risk model based on these variables could be useful to provide relevant information concerning metastasis relapse probability and necessity of close follow-up for these patients.

Neurofibroma and epidermoid cyst: unexpected findings after first foreskin retraction.

We report here 2 unusual cases of tumor of the glans penis in children. Abnormal findings were found on a 12-year-old and a 13-year-old boy soon after their first foreskin retraction. Initial medical examination suggested inclusions of smegma and they were referred to our Department of Pediatric Urology. Complete resection was performed under general anesthesia. Histologic examination revealed an epidermoid cyst in the first patient and a solitary neurofibroma in the second. These patients represent respectively the third and the second cases of such entities described in the pediatric age group. Cautious examination is required for persistent inclusions of smegma.

Influence of positive surgical margin status after radical nephroureterectomy on upper urinary tract urothelial carcinoma survival.

BACKGROUND: The influence of a positive surgical margin (PSM) on survival outcome of post radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UUT-UC) is unclear. The objectives of this study were to determine the significance of PSM on cancer-specific survival (CSS), recurrence-free survival (RFS), and metastasis-free survival (MFS) post RNU. METHODS: From a multicenter collaborative database, data on SM status, stage, grade, lymph node status, lymphovascular invasion (LVI), tumor location, follow-up, and survival was retrieved for 472 patients. Patients underwent open RNU with bladder cuff excision. Clinicopathological features were compared using χ(2) or Fisher exact test and unpaired t test for categorical and continuous variables, respectively. Survival was estimated using the Kaplan-Meier method, and univariate and multivariate Cox proportional hazards regression models were calculated. RESULTS: Median follow-up was 27.5 months (12.1-49.3 months). PSM was identified in 44 patients (9.3%) and correlated with pT stage (p = 0.002), grade (p < 0.001), LVI (p < 0.001), and location (p < 0.001). Univariate analyses revealed that PSM was a poor prognostic factor for CSS, RFS, and MFS (p = 0.003, 0.04, and <0.001, respectively). The 5-yr CSS and MFS for PSM was 59.1 and 51.6%, respectively, compared with 83.3 and 79.3% for patients with negative SM. Multivariate analyses revealed that SM status was an independent predictor of MFS [hazard ratio 2.7; p = 0.001). CONCLUSIONS: PSM after RNU is an important prognostic factor for developing UUT-UC metastases. The status of the surgical margin should be systematically reported on the pathological report and may be a useful variable to include in nomogram risk prediction tools.

The role of American Society of Anesthesiologists scores in predicting urothelial carcinoma of the upper urinary tract outcome after radical nephroureterectomy: results from a national multi-institutional collaborative study.

UNLABELLED: Study Type--Prognosis (cohort) Level of Evidence 2b. What'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.
