Radical cystoprostatectomy (RCP) followed by bilateral pelvic lymphadenectomy and urinary diversion remains the gold-standard therapy for men with localized muscle-invasive bladder cancer (MIBC). Prostate cancer might be incidentally detected at the time of RCP with a reported prevalence of 24-51%. Typically, these patients are considered to have clinically insignificant disease, but data from emerging series challenge this assumption and suggest that some of these tumours might be aggressive, or somehow increase the aggressiveness of the associated MIBC, and can negatively influence the patient's overall survival outcomes...

BACKGROUND: Although high risk HPVs are associated with an increased risk of prostate cancer it is not known if they have a causal role. The purpose of this study is to investigate the potential role of human papilloma viruses (HPVs) in prostate cancer. The aims are (i) to investigate the presence and confirm the identity of high risk HPVs in benign prostate tissues prior to the development of HPV positive prostate cancer in the same patients, and (ii) to determine if HPVs are biologically active...

CONTEXT: Renal transplantation is the gold standard renal replacement therapy in end-stage renal disease owing to its superior survival and quality of life compared with dialysis. When the potential recipient has a history of cancer, the waiting period before radiotherapy is usually based on the Cincinnati Registry. OBJECTIVE: To systematically review all available evidence on the risk of cancer recurrence in end-stage renal disease patients with a history of urological cancer...

INTRODUCTION: Active surveillance is a strategy to delay or prevent treatment of indolent prostate cancer. The Prostate Cancer Research International: Active Surveillance (PRIAS) criteria were developed to select patients for prostate cancer active surveillance. The objective of this study was to compare pathological findings from PRIAS-eligible and PRIAS-ineligible clinically low-risk prostate cancer patients. METHODS: A D'Amico low-risk cohort of 1512 radical prostatectomy patients treated at The Ottawa Hospital or Memorial Sloan Kettering Cancer Centre between January 1995 and December 2007 was reviewed...

BACKGROUND: Atopy has been investigated as a potential risk factor for prostate cancer. IgE antibodies may be major players in protective responses against tumours, through engendering antigen presentation and enhancing adaptive immune responses targeted towards a specific allergen, but potentially also against tumour-associated antigens such as prostate-specific antigen (PSA). We therefore cross-sectionally investigated associations between circulating levels of PSA and IgE in the National Health and Nutrition Examination Survey 2005-2006...

The miR-183 cluster, which is comprised of paralogous miRs-183, -96 and -182, is overexpressed in many cancers, including prostate adenocarcinoma (PCa). Prior studies showed that overexpression of individual pre-miRs-182, -96 and -183 in prostate cells decreased zinc import, which is a characteristic feature of PCa tumours. Zinc is concentrated in healthy prostate 10-fold higher than any other tissue, and an >80% decrease in zinc is observed in PCa specimens. Here, we studied the effect of overexpression of the entire 4...

BACKGROUND: Salvage radiation therapy (SRT) is a recommended treatment option for biochemical recurrence after radical prostatectomy (RP). However, its effectiveness may be limited to specific categories of patients. OBJECTIVE: We aimed to identify the optimal candidates for early SRT after RP. DESIGN, SETTING, AND PARTICIPANTS: The study included 925 node-negative patients treated with SRT after RP at seven institutions. Patients received SRT for either prostate-specific antigen (PSA) rising, or PSA persistence after RP that was defined as PSA level ≥0...

Cement augmentation via percutaneous vertebroplasty or kyphoplasty for treatment of spinal metastasis is a well-established treatment option. We assessed whether elevated intrametastatic pressure during cement augmentation results in an increased dissemination of tumour cells into the vascular circulation. We prospectively collected blood from patients with osteolytic spinal column metastases and analysed the prevalence of circulating tumour cells (CTCs) at three time-points: preoperatively, 20 minutes after cement augmentation, and 3-5 days postoperatively...

Hypoxia-inducible factors (HIFs) play a central role in the transcriptional response to changes in oxygen availability. Stability of HIFs is regulated by multi-step reactions including recognition by the von Hippel-Lindau tumour suppressor protein (pVHL) in association with an E3 ligase complex. Here we show that pVHL physically interacts with fatty acid synthase (FASN), displacing the E3 ubiquitin ligase complex. This results in HIF-α protein stabilization and activation of HIF target genes even in normoxia such as during adipocyte differentiation...

TMEFF2 is a type I transmembrane protein with two follistatin (FS) and one EGF-like domain over-expressed in prostate cancer, however its biological role in prostate cancer development and progression remains unclear, which may, at least in part, be explained by its proteolytic processing. The extracellular part of TMEFF2 (TMEFF2-ECD) is cleaved by ADAM17 and the membrane-retained fragment is further processed by the gamma-secretase complex. TMEFF2 shedding is increased with cell crowding, a condition associated with the tumour microenvironment, which was mediated by oxidative stress signalling, requiring jun-kinase (JNK) activation...

Pyridoxal 5'-phosphate (PLP) is the most important cofactor of vitamin B₆-dependent enzymes, which catalyses a wide range of essential body functions (e.g., metabolism) that could be exploited to specifically target highly metabolic cells, such as tumour metastatic cells. However, the use of PLP as a simultaneous coating and targeting molecule, which at once provides colloidal stability and specific biological effects has not been exploited so far. Therefore, in this work iron oxide nanoparticles (IONPs) were coated by PLP at two different pH values to tune PLP bonding (e...

OBJECTIVE: The current WHO classification categorises high grade neuroendocrine (NE) carcinomas of the prostate into small cell and large cell types. A distinct form of carcinoma demonstrating synchronous dual exocrine and NE differentiation, termed amphicrine carcinoma, has been described at various other sites, primarily within the gastrointestinal tract. In this study, we describe the clinicopathologic features of a series of metastatic prostatic carcinomas with amphicrine features...

BACKGROUND: Evaluation of responses to treatment for metastatic castration-resistant prostate cancer (mCRPC) remains challenging. Consensus criteria based on prostate-specific antigen (PSA) and clinical and radiologic biomarkers are inconsistently utilized. Circulating tumor cell (CTC) counts can inform prognosis and response, but are not routinely used. OBJECTIVE: To evaluate the use of biomarkers and trends in clinical decision-making in current mCRPC treatment...

A 54-year-old man with progressive prostate cancer underwent a (68)Ga-PSMA-PET/CT, which showed lymph node and bone metastases. After 2-cycles of (177)Lu-PSMA therapy, the repeated (68)Ga-PSMA PET/CT showed decreased radiotracer uptake in lymph node and bones metastases, but there were new lesions which may be compatible with progression or tumour sink-effect. A review of (177)Lu-PSMA-therapy images revealed that new lesions in the second PET/CT were the metastatic lesions that progressed after the first PET/CT, and subsequently showed a good response...
