The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve analysis.Results: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, p<0.001), PBT (one unit: HR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: HR 1.72, 95% CI 1.29-2.29, p<0.001), bilateral hydronephrosis (HR 1.54, 95% CI 1.21-1.97, p<0.001), squamous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, p<0.001), lymph node status (HR 1.53, 95% CI 1.21-1.95, p<0.001), and lymphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the nomogram.Conclusion: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.展开更多

We aim to share our experience on laparoscopic radical cystectomy and to evaluate our morbidity and oncological outcome in our settings. Methodology: An observational study in the Douala Medico-Surgical Urology Centre on 5 patients who underwent laparoscopic cystectomy with or without lymph node dissection and external urine diversion between April 2014 to July 2016 was conducted. The overall survival rate was subsequently estimated. Results: Four men and one woman underwent laparoscopic radical cystectomy during the 5-year study period with a mean age of 54.5-year-old. Three patients were submitted to ileal conduits, one to neobladders, and one patient to uretero-cutaneostomies. The mean operative time was 300 ± 17 minutes and the mean length of hospital stay was 9 ± 3 days. Three patients had minor complications according to Clavien and Dindon Classification treated conservatively without need for further operation. Four patients had transitional cell carcinoma and one Squamous cell carcinoma types. Everyone had negative resection margin while only two had negative lymph node. The median survival years in our study was 2.5 years, the overall survival rates at 2 years were 60%, 40% at 3 years and 20 at 5years. 2 patients die after one year due to renal failure and intercurrent disease. Conclusion: Laparoscopic radical cystectomy carried lower morbidity and cancerological outcome compare to open surgery making it a good alternative for bladder oncologic surgery.展开更多
