Radiation after radical prostatectomy in elderly patients - a SEER database-derived competing-risk survival analysis of propensity score-matched age groups.

Introduction: This study aimed to evaluate cancer-specific (CSM) and other-cause mortality (OCM) in elderly patients with prostate cancer treated with radical prostatectomy (RP) and postoperative radiotherapy (RT).

Material And Methods: The Surveillance, Epidemiology, and End Results (SEER) database was searched for clinically non-metastatic prostate cancer (PCa) treated with RT after RP between 2010 and 2015. Patients were stratified according to age groups and underwent propensity score (PS) matching.

Upper Urinary Tract Urothelial Cancer After Radical Cystectomy for Bladder Cancer: Survival Outcomes After Radical Nephroureterectomy.

Background: Systemic and local recurrences of urothelial bladder cancer (UBC) significantly impair survival after radical cystectomy (RC), but little is known about the impact of the recurrence of urothelial cancer in the upper urinary tract (UTUC). This report describes survival outcomes and their predictors for patients who underwent RC followed by radical nephroureterectomy (RNU) for UTUC.

Methods: The Surveillance, Epidemiology, and End Results database was queried to identify patients who underwent RC for UBC and subsequent RNU for UTUC.

Cancer-Specific Survival of Patients with Non-Muscle-Invasive Bladder Cancer: A Population-Based Analysis.

Background And Purpose: Non-muscle-invasive bladder cancer (NMIBC) constitutes a heterogeneous group of tumors with different prognoses. This population-based study aimed to report real-world cancer-specific survival (CSS) of NMIBC and create a prognostic nomogram based on the identified risk factors.

Methods: The Surveillance, Epidemiology, and End Results database was searched for patients diagnosed with NMIBC from 2004 to 2015, who underwent transurethral resection of the bladder tumor.

Human kidney injury molecule-1 as a urine biomarker differentiating urothelial and renal cell carcinoma.

Introduction: Urine concentration of human kidney injury molecule-1 (KIM-1) is suggested to be increased in patients with renal cell carcinoma (RCC). However, it has never been tested in patients with urothelial tumors, while preoperative differentiation between RCC and upper tract urothelial carcinoma (UTUC) plays an essential role in therapeutic decisions.The aim of the study was to evaluate the role of urinary KIM-1 expression in preoperative differentiation between RCC and urothelial carcinoma (UC).

Feasibility of active surveillance in small testicular mass: a mini review.

Introduction: Widespread use of scrotal ultrasonography has led to the detection of incidental, non-palpable small testicular masses (STMs). Historically, all intratesticular masses were treated radically, however more conservative strategies are now being applied with growing evidence that up to 80% of STMs are benign lesions. Testis-sparing surgery is deemed a gold standard in STMs.
