Background: Active surveillance (AS) is increasingly used to monitor patients with lower risk prostate cancer (PCa). The Prostate Cancer Active Lifestyle Study (PALS) was a randomized controlled trial to determine whether weight loss improves obesity biomarkers on the causal pathway to progression in patients with PCa on AS.
Methods: Overweight/obese men (body mass index >25 kg/m) diagnosed with PCa who elected AS were recruited.
Introduction: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by cystectomy is the standard for muscle-invasive bladder cancer (MIBC), however, NAC confers only a small survival benefit and new strategies are needed to increase its efficacy. Pre-clinical data suggest that in response to DNA damage the tumor microenvironment (TME) adopts a paracrine secretory phenotype dependent on mTOR signaling which may provide an escape mechanism for tumor resistance, thus offering an opportunity to increase NAC effectiveness with mTOR blockade.
Patients & Methods: We conducted a phase I/II clinical trial to assess the safety and efficacy of gemcitabine-cisplatin-rapamycin combination.
The NCCN Clinical Practice Guidelines in Oncology for Bladder Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer. These NCCN Guidelines Insights discuss important updates to the 2018 version of the guidelines, including implications of the 8th edition of the AJCC Cancer Staging Manual on treatment of muscle-invasive bladder cancer and incorporating newly approved immune checkpoint inhibitor therapies into treatment options for patients with locally advanced or metastatic disease.

Patient characteristics such as age, race, and Agent Orange (AO) exposure may influence advisability of AS in veterans. The 17-gene assay may improve risk stratification and management selection.

The complete version of the NCCN Guidelines for Bladder Cancer addresses additional aspects of the management of bladder cancer, including non-muscle-invasive urothelial bladder cancer and nonurothelial histologies, as well as staging, evaluation, and follow-up.

Recent updates include (1) refining the recommendation of intravesical bacillus Calmette-Guérin, (2) strengthening the recommendations for perioperative systemic chemotherapy, and (3) incorporating immunotherapy into second-line therapy for locally advanced or metastatic disease. These NCCN Guidelines Insights further discuss factors that affect integration of these recommendations into clinical practice.

Methods: Prospective cohort study comparing adherence with generic and cancer-specific guidelines on processes of surgical care between AI/AN and non-Hispanic white (NHW) patients in Washington State (2010 to 2014) was conducted.
Results: A total of 156 AI/AN and 6,030 NHW patients underwent operations for 10 different cancers, and had similar mean adherence to generic surgical guidelines (91.
Purpose: Radical cystectomy is associated with high complication and rehospitalization rates. An understanding of the root causes of hospital readmissions and the modifiability of factors contributing to readmissions may decrease the morbidity associated with radical cystectomy. We characterize the indications for rehospitalization following radical cystectomy, and determine whether these indications represent immutable patient disease and procedure factors or whether they are modifiable.

As the median age of diagnosis is 73, many patients are elderly at the time of cystectomy. We compare perioperative surgical outcomes in elderly patients undergoing robotic vs open radical cystectomy (RC).

Animal and in-vitro prostate cancer (PCa) models have demonstrated decreased tumor growth with metformin, however the precise mechanisms are unknown. We examine the effects of metformin on PCa biochemical recurrence (BCR) in a large clinical database followed by evaluating metabolic signaling changes in a cohort of men undergoing prostate needle biopsy (PNB).

A better understanding of the incidence and timing of VTE would clarify chemoprophylaxis strategies among RC patients. We sought to characterize the burden of VTE after RC by defining their timing and effect utilizing the MarketScan commercial databases.

Causes for this disparity are unknown. The authors of this report examined the receipt of cancer treatment among AI/AN patients compared with white patients.

Extended antibiotic prophylaxis beyond 24 hours may contribute to hospital acquired infections such as Clostridium difficile colitis. We evaluated practice patterns of antibiotic prophylaxis in genitourinary cancer surgery and assessed the impact of antibiotic prophylaxis on hospital acquired C.

Patients And Methods: We retrospectively reviewed data from patients with clinical T2-T4N0-1 urothelial carcinoma of the bladder who underwent RC at our institution between July 2005 and November 2011. Degree of TUR was derived from review of operative reports.
Background: The delivery of urologic oncology care is susceptible to regional variation. In the current study, the authors sought to define patterns of care for patients undergoing genitourinary cancer surgery to identify underserved areas for urologic cancer care in Washington State.
Methods: The authors accessed the Washington State Comprehensive Hospital Abstract Reporting System from 2003 through 2007.
Background: Cisplatin-based neoadjuvant chemotherapy (NC) is commonly used in the treatment of muscle-invasive urothelial cell carcinoma of the bladder (UC) and has been shown to improve survival. However, not all patients respond to NC, thus delaying the interval to potentially curative surgical therapy, risking disease progression and subjecting patients to potential morbidity from NC. In this study, we perform a retrospective analysis of patients who received NC prior to cystectomy to identify factors associated with nonresponse.

Methods: Using 2004-2006 SEER Limited-Use Data, 51,982 early prostate cancer patients were identified (T1c, T2a, T2b, T2c, T2NOS; no metastases) who were most likely to benefit from definitive treatment (< 75 years old, Gleason score < 8, PSA ≤ 20).
Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years.

Bladder cancer is the fourth most common cancer in the United States. Urothelial carcinoma that originates from the urinary bladder is the most common subtype. These NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) provide recommendations on the diagnosis and management of non-muscle-invasive and muscle-invasive urothelial carcinoma of the bladder.

However, the persistence of an increased risk for UC following smoking cessation is not well established. We assessed the risk of UC among former smokers using a recent, prospective cohort with a high proportion of former smokers.

Quality-improvement initiatives are beginning to lead to improvements in the quality of care and coordination amongst teams in the operating room. As the population ages and patients present with more complex disease pathology, the demands for efficient systematization will increase.

An automated bladder surveillance system is being developed to robotically scan the bladder surface using an ultrathin and highly flexible endoscope. Such a system would allow cystoscopic procedures to be overseen by technical staff while urologists could review cystoscopic video postoperatively.
