Galectin-9 as a prognostic and predictive biomarker in bladder urothelial carcinoma Galectin-9, a member of the “tandem repeat” type galectins performing as animal lectins with an affinity for β-galactosides, has been well documented to exert crucial functions in immunomodulation, survival, and growth of various tumors. This study aims to reveal the clinical significance of galectin-9 in urothelial carcinoma of the bladder (UCB) postoperatively.
Genitourinary paraganglioma: Demographic, pathologic, and clinical characteristics in the surveillance, epidemiology, and end results database (2000–2012) Extra-adrenal paragangliomas (PGLs) are infrequent, benign, and neuroendocrine tumors arising from chromaffin cells of the autonomic nervous system. Most PGLs are sporadic, but up to 32% are associated with inherited syndromes such as neurofibromatosis type 1, von Hippel-Lindau disease, and familial PGL. Although most PGLs develop above the umbilicus, they have been reported in the genitourinary (GU) tract. Owing to the paucity of literature on the rates of GU PGL, the objective of our study is to describe the demographic, pathologic, and clinical characteristics of GU PGL, and compare them to non-GU sites of PGL using the surveillance, epidemiology, and end results (SEER) database.
Is The Cancer Genome Atlas (TCGA) bladder cancer cohort representative of invasive bladder cancer? The Cancer Genome Atlas (TCGA) Research Consortium has conducted a comprehensive molecular characterization of invasive bladder cancer (BCa). This open-access dataset has become the critical reference for studying biomarkers and mechanisms of disease in BCa. In order for this data to be considered representative, and to allow comparisons of markers between cohorts, clinicopathologic characteristics of this cohort need to conform to those established for this disease state. The aim of this study was to critically evaluate clinicopathologic characteristics and outcomes of the TCGA BCa cohort in comparison with published cystectomy series.
GSTM1 genotype is an independent prognostic factor in clear cell renal cell carcinoma Owing to dual functionality of cytosolic glutathione S-transferases (GSTs), they might affect both the development and the progression of renal cell carcinoma (RCC). However, the data on the prognostic value of GST polymorphism in patients with RCC are scarce. Hence, we evaluated the effect of GST gene variants on both the risk of RCC development and the postoperative prognosis in patients with clear cell RCC (ccRCC).
Navigating the evolving therapeutic landscape in advanced prostate cancer Prostate cancer is the most common cause of cancer in men, with 137.9 new cases per 100,000 men per year. The overall 5-year survival rate for prostate cancer is very high. Up to 20% of men who undergo state-of-the art treatment for prostate cancer will develop castration-resistant prostate cancer (CRPC) within 5 years, with median survival for those with metastatic CRPC ranging from approximately 15 to 36 months in recent studies. With the advent of several new drugs in the past 5 years to treat CRPC, the challenge facing clinicians is how to best sequence or combine therapies or both to optimize outcomes.
Nivolumab treatment for advanced renal cell carcinoma: Considerations for clinical practice Nivolumab is an important new therapy option for patients with advanced renal cell carcinoma, and has a different mechanism of action compared with vascular endothelial growth factor -targeted therapies. It is a programmed death 1 immune checkpoint inhibitor antibody with response patterns, efficacy, and safety profiles that differ from those of conventional antiangiogenic or mammalian target of rapamycin inhibition therapy.
Inhibition of hTERT expression by MAP kinase inhibitor induces cell death in renal cell carcinoma Human telomerase reverse transcriptase (hTERT) is one of the components of telomerase enzyme and its activity is associated with cell proliferation and differentiation. Extracellular signal regulated kinase (ERK)-mitogen activated protein kinase signaling pathway play an important role in hTERT expression. The present study was conducted to ascertain hTERT messenger RNA (mRNA) expression in renal cell carcinoma (RCC) and its association with clinicopathological characteristics. Further, we also explored hTERT targeting as possible tumor therapeutic.
Current guidelines do not sufficiently discriminate venous thromboembolism risk in urology Venous thromboembolism (VTE) is the leading cause of noncancer death following major cancer surgery. Current thromboprophylaxis guidelines do not address procedure-specific risk of venous thromboembolism for urological patients. This project was created to determine the risk and timing of VTE after major urological surgery and to evaluate if surgical procedure was an independent risk factor for VTE after adjusting for previously established risk factors.

Role of radical prostatectomy in metastatic prostate cancer: A review Recent demonstration of efficacy with the use of chemohormonal therapy for men with metastatic prostate cancer (mPCa) has expanded the therapeutic options for these patients. Furthermore, multimodal therapy to treat systemic disease in the context of locoregional control has gained increasing interest. Concomitantly, the role of radical prostatectomy (RP) in multimodal treatment for locally advanced prostate cancer is expanding. As a result, there is interest in investigating the potential benefit of cytoreductive RP in mPCa.
A prospective study of health-related quality-of-life outcomes for patients with low-risk prostate cancer managed by active surveillance or radiation therapy Patients with low-risk prostate cancer (PCa) often have excellent oncologic outcomes. However, treatment with curative intent can lead to decrements in health-related quality of life (HRQoL). Patients treated with radical prostatectomy have been shown to suffer declines in urinary and sexual HRQoL as compared to those managed with active surveillance (AS). Similarly, patients treated with external-beam radiation therapy (EBRT) are hypothesized to experience greater declines in bowel HRQoL. As health-related quality-of-life (HRQoL) concerns are paramount when selecting among treatment options for low-risk PCa, this study examined HRQoL outcomes in men undergoing EBRT as compared to AS in a prospective, racially diverse cohort.
External histopathological validation of the surface-intermediate-base margin score The surface, intermediate, and basis (SIB) is a system based on surgeon׳s visual assessment of the thickness of healthy parenchyma remaining on the intrarenal portion of the tumor. This system has been proposed to standardize the nomenclature of the resection technique (RT) during partial nephrectomy (PN). Our study aims at evaluating whether the SIB score visually assigned is related to the thickness of parenchyma measured by microscopy.
Does teaching of robotic partial nephrectomy affect renal function and perioperative outcomes? Partial nephrectomy (PN) represents the treatment of choice for localized renal tumor<7cm. Minimally invasive approaches are considered standard of care in many institutions. Maintaining acceptable warm ischemic time (WIT) while teaching robotic PN (RPN) remains challenging. The goal of the present study was to assess the effect of teaching RPN on WIT and renal function in patients undergoing RPN.
Quality indicators in the management of bladder cancer: A modified Delphi study Survival in patients with bladder cancer has only moderately improved over the past 2 decades. A potential reason for this is nonadherence to clinical guidelines and best practice, leading to wide variations in care. Common quality indicators (QIs) are needed to quantify adherence to best practice and provide data for benchmarking and quality improvement.
Utilization of perioperative systemic chemotherapy in upper tract urothelial carcinoma Evidence for the use of perioperative chemotherapy (PC) in upper tract urothelial carcinoma (UTUC) is largely derived from level I evidence for invasive urothelial carcinoma of the bladder (UCB). There has been an increase in PC for urothelial carcinoma of the bladder, as it has disseminated into clinical practice. Therefore, we sought to not only analyze trends in the utilization of PC in UTUC, but also assess factors associated with its use in a large cancer registry database.
Star reviewers for Urologic Oncology Although the quality of any medical journal depends upon the quality of manuscripts received, the backbone of a journal׳s success is created by those who review manuscripts, identify problematic issues, make critical suggestions for improvement, and assist the journal׳s editors in deciding on a manuscript׳s disposition. This is no small task, and all too often it may feel thankless.
