Over the past decade, genomic and transcriptomic analyses have uncovered promising tumor antigens including immunotherapeutic targets in bladder cancer (BCa). Conventional tumor antigens are proteins expressed on the plasma membrane of tumor cells such as EGFR, FGFR3, and ERBB2 in BCa, which can be targeted by antibodies or similar epitope-specific binding reagents. The cellular proteome consists of ∼100,000 proteins but the expression of these proteins is rarely unique to tumor cells. Many tumor-associated proteins are post-translationally modified with phosphorylation, glycosylation, ubiquitination, or SUMOylation moieties...

BACKGROUND: Alpha methylacyl A coenzyme racemase (AMACR) has shown to be an excellent immunohistological biomarker for prostate cancer (CaP). Given the connection between prostate and urethra, we hypothesized that semen ejaculate would be an ideal specimen for detection of CaP specific biomarkers, such as AMACR. This study explores the detection of semen AMACR protein in men with and without CaP. METHODS: Semen ejaculates from 28 biopsy proven CaP patients prior to radical prostatectomy and 15 age-comparable controls were analyzed...

OBJECTIVES: High-grade nonmuscle-invasive urothelial tumors of the bladder that fail intravesical Bacillus Calmette-Guérin (BCG) immunotherapy are at the highest risk of progression. Initial evidence links heat shock protein expression levels and outcome of bladder cancer after BCG treatment. We aimed to determine the association between HSP60, 70, and 90 expression levels and long-term outcomes of T1 high-grade (T1HG) urothelial bladder tumors treated with BCG immunotherapy. MATERIALS AND METHODS: Data of 54 consecutive patients with primary T1HG bladder tumors who underwent transurethral resection between 2002 and 2008 and received at least an induction course of BCG were reviewed...

INTRODUCTION: Bladder cancer (BC) is diagnosed by cystoscopy, which is invasive, costly and causes considerable patient discomfort. MicroRNAs (miR) are dysregulated in BC and may serve as non-invasive urine markers for primary diagnostics and monitoring. The purpose of this study was to identify a urinary miR signature that predicts the presence of BC. METHODS: For the detection of potential urinary miR markers, expression of 384 different miRs was analyzed in 16 urine samples from BC patients and controls using a Taqman™ Human MicroRNA Array (training set)...

OBJECTIVE: Antibodies against carbonic anhydrase IX (CAIX) are often part of immunohistochemical panels used to assist renal cell cancer (RCC) subtyping. This study was undertaken to determine, whether assessing CAIX expression levels could provide additional prognostic information. METHODS AND MATERIALS: More than 1,800 RCCs were analyzed in a tissue microarray (TMA) format for CAIX expression. All tumors had been reviewed and newly classified according to the WHO 2016 classification...

INTRODUCTION: As the transgender patient population continues to increase, urologists and other providers who treat genitourinary malignancies will increasingly encounter cases of prostate cancer in transgender women. Little exists in the current literature to help summarize the challenges and opportunities which face this unique patient population. Similarly, little exists to provide guidance on how we may best diagnose, manage, and follow transgender women diagnosed with prostate cancer...

We conducted a systematic network meta-analysis to review the relevant literature evaluating the therapeutic efficacy of upfront docetaxel (Doc) or abiraterone (Abi) plus androgen deprivation therapy (ADT) on oncological outcome in patients with castration-naïve prostate cancer (CNPC). An attempt to identify subgroups of patients who would benefit most either from Doc or Abi plus ADT and further compare the efficacy and safety between these two combination therapies was made. A comprehensive search of the PubMed/Medline, Embase databases, International Clinical Trial Registration Platform (ICTRP), Clinical Trial, and Cochrane Central Register of Controlled Trials to December 2017 was performed...

Penile squamous cell carcinoma is a rare cancer in men. The main prognosticators of survival for penile cancer patients remain the presence and the extent of lymph node metastasis. While radical inguinal lymphadenectomy has been the cornerstone of regional lymph node management for many years, it is still associated with significant morbidity and psychological distress. Recent developments in penile squamous cell carcinoma management have been met with some controversy in the urologic oncology community. Herein, we review the current controversies and developments on the role of inguinal lymphadenectomy for penile cancer...

BACKGROUND: Despite important results achieved for metastatic renal cell carcinoma, some patients could benefit from local treatments or an initial active surveillance (AS) period for recurrent disease. We aim to analyze: changes in the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk class, the number of metastases and the disease burden from the start of AS to the beginning of systemic therapy; and if these changes influenced patient outcomes. PATIENTS AND METHODS: Patients who started AS at our institution from January 2007 to April 2016 were included...

OBJECTIVE: Tumor enucleation has been shown to be oncologically safe for elective treatment of renal cell carcinoma (RCC); yet, evidence on long-term oncologic outcomes after robotic tumor enucleation is lacking. In this study we provide a detailed histopathological analysis of tumor-parenchyma interface and the long-term oncologic outcomes after robotic tumor enucleation for sporadic RCC in a high-volume referral center. MATERIALS AND METHODS: We selected consecutive patients undergoing robotic tumor enucleation for sporadic RCC by experienced surgeons with at least 4 years of follow-up...

Innervation of prostate cancer (CaP) tissue favors tumor progression and metastasis but the regulation of innervation in CaP is unclear. The oncogenic transcription factor ERG is commonly induced by a typical TMPRSS2-ERG (TE) gene fusion in CaP and may affect innervation. Here, we analyzed whether nerve density of CaP tissue is related to TE status or perineural infiltration status of CaP tissue. In parallel, we measured several members of the neuropilin/plexin/semaphorin family (NRP, PLXN, and SEMA) as possible targets mediating innervation...

BACKGROUND: The advantages of Robot-assisted laparoscopic prostatectomy (RARP) over open radical prostatectomy (ORP) in Prostate cancer perioperatively are well-established, but quality of life is more contentious. Increasingly, patients are utilising online cancer support groups (OCSG) to express themselves. Currently there is no method of analysis of these sophisticated data sources. We have used the PRIME-2 (Patient Reported Information Multidimensional Exploration version 2) framework for automated identification and intelligent analysis of decision-making, functional and emotional outcomes in men undergoing ORP vs...

BACKGROUND: Clostridium difficile infection (CDI) is an important cause of hospital acquired morbidity with implications for quality of care. Radical cystectomy is a surgical procedure associated with high rates of morbidity one of which is a high rate of CDI. The rate of CDI among patients undergoing radical cystectomy may be estimated based on the reports from single institutions or by querying national databases. This study aims to compare rates of CDI reported in single institution series with rates obtained from national datasets...

In attempt to improve long-term disease control outcomes for high-risk prostate cancer, numerous clinical trials have tested the addition of chemotherapy (CTX)-either adjuvant or neoadjuvant-to definitive local therapy, either radical prostatectomy (RP) or radiation therapy (RT). Neoadjuvant trials generally confirm safety, feasibility, and pre-RP PSA reduction, but rates of pathologic complete response are rare, and no indications for neoadjuvant CTX have been firmly established. Adjuvant regimens have included CTX alone or in combination with androgen deprivation therapy (ADT)...

Recently, a plethora of life-prolonging cytotoxic, next-generation hormonal, immunotherapeutical as well as radionuclide therapies has emerged as a standard care for metastasized castration-resistant prostate cancer. Being strikingly effective in cancer control, these novel therapies might in fact exert a beneficial impact on skeletal events. Therefore, combining anticancer drugs with osteoprotective agents might lead to additional clinical advantage but must be weighed against simultaneously exposing patients to serious toxicities...
