Bladder Cancer Recurrence

Bladder cancer remains one of the most common malignancies of the genitourinary tract. Transurethral resection of the bladder tumor (TURBT) via cystoscopy with examination under anesthesia remains the primary method for determining the diagnosis and clinical stage of bladder cancer. Given the substantial cost of treatment and risk of bladder cancer recurrence after TURBT, novel approaches to transurethral resection, such as the en bloc technique, have been developed in an attempt to address these limitations. In this review, we examined the postoperative and oncological outcomes of en bloc TURBT compared to traditional resection techniques. Further prospective clinical studies, however, are still necessary to determine whether these alternative technologies or surgical techniques may improve treatment in bladder cancer patients. Level of evidence: Not applicable.

Purpose: The aim of this work was to investigate the predictive factors for bladder cancer recurrence survival (BCRS) in patients with upper-tract urothelial carcinoma (UTUC). Methods: We selected patients with UTUC who underwent segmental ureterectomy (Su) or nephroureterectomy (Nu) from 2004 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with a history of intravesical therapy for bladder cancer and bladder cancer prior to the diagnosis of UTUC were excluded. We used Kaplan-Meier analysis, log-rank tests, and Cox proportional hazards model to compare overall survival, cancer-specific survival, and BCRS. Results: In a cohort of 1,454 patients, 169 (11.6%) had low-grade tumors and 1,285 (88.4%) had high-grade tumors; 239 (16.4%) underwent Su and 1,215 (83.6%) underwent Nu. We found that T4 grade (hazard ratio [HR] = 6.216; 95% confidence interval [CI], 3.197-12.087) and ureteral tumors (HR = 1.764; 95% CI, 1.173-2.652) were predictors of shorter BCRS, whereas Nu (HR = 0.608; 95% CI, 0.388-0.953) predicted longer BCRS. Five-year BCRS rates were low-grade tumors: 94.1%, high-grade tumors: 85.4% (p = 0.038); plus Su: 82.9%, and Nu: 87.6% (p = 0.016). Conclusions: Use of Su should be more selective for high-grade tumors, as it correlates with shorter BCRS. Tumors located in the ureter are associated with shorter BCRS than those located in the renal pelvis.
