PURPOSE: A prospective study of partial vs. radical nephrectomy demonstrated worse overall survival in patients undergoing partial nephrectomy which appeared to be driven by cardiovascular outcomes. We sought to determine if the blood pressures or use of antihypertensive medications differed between patients who underwent partial or radical nephrectomy. MATERIALS AND METHODS: A tertiary-referral institutional renal mass database was queried for patients between 2006 and 2012 undergoing partial or radical nephrectomy...

BACKGROUND AND OBJECTIVE: Small kidney cancers are a heterogeneous group with varying malignant potential. Pathologic information obtained from a renal biopsy may guide decision-making for small kidney cancers. We sought to assess the effect of pathologic information from renal biopsy on the nonsurgical management of small kidney cancers in a population-based cohort of patients over 65 years of age. METHODS: In the Surveillance, Epidemiology and End Results-Medicare dataset, we identified patients ≥66 years diagnosed with a kidney cancer<4cm between 2002 and 2011...

INTRODUCTION: Testicular seminoma affects relatively young men with excellent survival outcomes. There has been increasing concern that radiotherapy (RT) leads to secondary malignant neoplasms (SMNs) and subsequent mortality. We evaluated the effect of RT on incidence of SMNs and quantified cancer-related mortality and other causes of death for patients with stage I and II testicular seminoma. MATERIAL AND METHODS: A national sample of men (1988-2013) diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminomas from Surveillance, Epidemiology, and End Results were evaluated...

The role of lymph node dissection (LND) in the management of renal cell carcinoma has been controversial. Older studies provided initial support to a potential survival benefit in resection of lymph node metastases, and several predictive models were developed to identify patients with lymph node involvement. However, the only randomized trial on the subject did not report a survival benefit to LND in the nonmetastatic setting. Several studies have recently reexplored the therapeutic benefit of LND. In both nonmetastatic and metastatic settings, LND does not appear to be associated with a survival benefit...

BACKGROUND: As the incidence of prostate cancer has, until recently, increased in most developed countries, the rates of prostate biopsies, required for histological diagnosis, will also have increased. Little is known about the physical after-effects of prostate biopsy outside randomised control trials. We investigate reports on the physical effect of prostate biopsy undertaken in men in routine practice. METHODS: A self-completed questionnaire was given to men living in the Republic of Ireland (RoI) or Northern Ireland 4 to 6 weeks after prostate biopsy...

Prioritization of patient and stakeholder engagement in the research process has been realized through increased funding and policy directives at the government level. Particularly, patient engagement in the preparatory research stage has driven development of patient-prioritized research questions. In this article, a successful example of patient-centered research prioritization is reviewed, and effective strategies and opportunities for patient engagement in urologic oncology research are described.

OBJECTIVES: Bladder urothelial carcinoma (UC) comprises more than 90% of all bladder cancers. Among several UC variants, micropapillary UC (MPUC) is a rare one with high potential for lymphovascular invasion and subsequent lymph node metastasis. Histologically, MPUC is characterized by the presence of small papillary carcinoma cell clusters surrounded by lacunar spaces. Immunohistochemically, the outer circumference of these clusters, that is, the stroma-facing membrane of carcinoma cells, is reportedly almost invariably positive for mucin 1 (MUC1) protein and to a lesser extent for sialyl Lewis X (sLeX) carbohydrates; however, the clinicopathological implications of these expression patterns have not been fully investigated...

BACKGROUND: Ki-67 for quantifying tumor proliferation is widely used. In localized prostate cancer (PCa), despite a suggested predictive role of Ki-67 for outcomes after therapies, it has not been incorporated into clinical practice. Herein, we conduct a systematic review and meta-analysis of the literature reporting the association of Ki-67 and disease outcomes in PCa treated radically. METHODS: Medline and EMBASE databases were searched without date or language restrictions, using "KI67" and "prostate cancer" MeSH terms...

OBJECTIVE: To determine whether a restrictive perioperative fluid management in the context of an enhanced recovery after surgery program for radical cystectomy and urinary diversion affects renal function, as fluid restriction and the use of vasopressors have been linked to impaired tissue perfusion, potentially resulting in renal dysfunction. METHODS: We followed 166 patients initially included in a randomized clinical trial and equally allocated to receive a continuous norepinephrine administration combined with 1ml/kg/h initially, and after cystectomy 3ml/kg/h crystalloid infusion (intervention group, n = 83), or a standard crystalloid infusion of 6ml/kg/h throughout surgery (control group, n = 83)...

BACKGROUND: Radical orchiectomy specimens present a unique set of challenges for pathology assessment owing to their rarity and complexity. This study compares second opinion pathology reports generated at a single, large academic institution to primary reports from outside hospitals. METHODS: A database search was conducted for orchiectomy cases that were sent to our institution for management of testicular cancer from 2014 to 2015. Cases sent for consultation without a finalized diagnosis from the outside hospitals were excluded...

OBJECTIVE: Sex differences in bladder cancer survival are well known. However, the effect of type of treatment, timing to surgery when rendered, and survival outcomes according to sex have not been extensively examined. Given the relatively low incidence of bladder cancer in females, large multicenter and population-based studies are required to elucidate sex differences in survival. In this study, we sought to characterize the effect of use and timing of radical cystectomy (RC) according to sex and survival outcomes...
