A 77-year-old man with castration-resistant prostate cancer (CRPC) received abiraterone acetate in October 2014. He visited our outpatient clinic because of general malaise and anorexia 27 days after starting abiraterone acetate. The lab test showed hepatic dysfunction (aspartate transaminase, AST 440 U/l, alanine transaminase, ALT 420 U/l) and the elevation of liver enzymes continued on the next day even after stopping abiraterone acetate. Three days later, he was hospitalized due to severe elevation of liver enzymes (AST 1,171 U/l, ALT 1,487 U/l) , and the decreased prothrombin activity (60...

Here we report the outbreak of bacteremia caused by Helicobacter cinaedi (H. cinaedi) in the urology ward. Case 1 was a man in his seventies with prostate cancer. Bacteremia caused by H. cinaedi developed 6 days after robot-assisted radical prostatectomy. Case 2 was a man in his sixties with small cell carcinoma of the prostate. Bacteremia developed at 5 days of docetaxel therapy. Case 3 was a man in his fifties with left renal pelvis carcinoma. Bacteremia developed 3 days after laparoscopic left nephroureterectomy...

In an attempt to develop effective and safe anticancer agents, we designed, synthesized and examined 23 novel quinacrine (QC) derivatives by combining the 9-aminoacridine scaffold and the [1,3]thiazinan-4-ones group. Most of these hybrids showed strong anticancer activities, among which 3-(3-(6-chloro-2-methoxyacridin-9-ylamino)propyl)-2-(thiophen-2-yl)-1,3-thiazinan-4-one (25; VR151) effectively killed many different cancer cell types, including eight breast cancer cell lines with different genetic background, two prostate cancer and two lung cancer cell lines...

PURPOSE OF REVIEW: Despite the worldwile increasing use of robotic assistance for oncology surgery, no level 1 evidence-based benefit favoring robot-assisted radical prostatectomy (RARP) versus pure laparoscopic or open approaches has been demonstrated. We aimed to perform an update of the available evidence by evaluating most recent 2016-2017 data. RECENT FINDINGS: Population-based and prospective nonrandomized studies and one phase III randomised trial have been recently published...

PURPOSE OF REVIEW: Examine and discuss novel focal therapy treatment options for prostate cancer. RECENT FINDINGS: With the widespread adoption of mpMRI-guided biopsies for prostate cancer, use of image-guided treatment of prostate cancer has increased. Focal therapies leading to partial gland ablation such as partial prostatectomy, focal laser ablation, irreversible electroporation, vascular targeted photodynamic therapy, and focal radiofrequency ablation have emerged and begun to be properly evaluated...

PURPOSE OF REVIEW: Options for prostate cancer management are rapidly expanding. The recent advent of MRI technology has led to guided prostate biopsies by radiologists working in-bore or by urologists using MR/US fusion technology. The resulting tumor visualization now provides the option of focal therapy. Currently available are highly directed energies - focused ultrasound (HIFU), cryotherapy, and laser - all offering the hope of curing prostate cancer with few side effects. RECENT FINDINGS: MRI now enables visualization of many prostate cancers...

We report a case of a 65-year-old man with prostate cancer; his treatment history included radical prostatectomy followed by radiation therapy and subsequent androgen deprivation therapy for more than 5 years. He currently presented with a history of rising prostate-specific antigen and complained of jaw aches. Ga-prostate-specific membrane antigen PET/CT study performed for suspected biochemical recurrence demonstrated vertebral lesions and lesion in his jaw. Subsequent biopsy of jaw lesion demonstrated prostate cancer metastases...

OBJECTIVE: Curcuma longa (C. longa) was used in some countries such as China and India for various medicinal purposes. Curcumin, the active component of C. longa, is commonly used as a coloring agent in foods, drugs, and cosmetics. C. longa and curcumin have been known to act as antioxidant, anti-inflammatory, anti-mutagen, and anti-carcinogenic agents. Th e attempt of the present review was to give an effort on a detailed literature survey concentrated on the protective effects of C...

OBJECTIVES: To determine the performance of Prostate Health Index (PHI) density (PHID) combined with MRI and prior negative biopsy (PNB) status for the diagnosis of clinically-significant prostate cancer (PCa). PATIENTS & METHODS: Patients without a prior diagnosis of PCa, with elevated PSA and a normal digital rectal exam who had PHI testing prospectively prior to prostate biopsy were included. PHID was calculated retrospectively using prostate volume derived from transrectal ultrasound at biopsy...

Aberrant reactivation of the Sonic Hedgehog (SHH) signaling pathway promotes prostate cancer (PC) growth and progression by regulating cancer-related genes through its downstream effectors GLI1 and GLI2. Therefore, targeting the SHH-GLI pathway provides an alternative approach to avoid cancer progression. The aim of this study was to delineate the underlying molecular mechanisms by which GDC-0449 (a SMO receptor inhibitor) and GANT-61 (a GLI transcription factor inhibitor) regulate cellular proliferation and self-renewal in human PC stem cells (ProCSCs)...

BACKGROUND: Because of the recent grade C draft recommendation by the US Preventive Services Task Force (USPSTF) for prostate cancer screening between the ages of 55 and 69 years, there is a need to determine whether this could be cost-effective in a US population setting. METHODS: This study used a microsimulation model of screening and active surveillance (AS), based on data from the European Randomized Study of Screening for Prostate Cancer and the Surveillance, Epidemiology, and End Results Program, for the natural history of prostate cancer and Johns Hopkins AS cohort data to inform the probabilities of referral to treatment during AS...

BACKGROUND: Definitive stereotactic body radiotherapy (SBRT) represents an emerging and debated treatment option for patients with prostate cancer, with potential economic savings and reports of short-term efficacy since 2006. The current study sought to define national trends in definitive prostate SBRT use and determine whether patterns vary by travel distance for treatment. METHODS: The National Cancer Data Base identified 181,544 men with localized prostate cancer who were treated with definitive external beam radiotherapy from 2004 through 2012...

The RPAR peptide, a prototype C-end Rule (CendR) sequence that binds to neuropilin-1 (NRP-1), has potential therapeutic uses as internalization trigger in anticancer nanodevices. Recently, the functionalization of gold nanoparticles with CendR peptides has been proved to be a successful strategy to target the NRP-1 receptor in prostate cancer cells. In this work, we investigate the influence of two gold surface facets, (100) and (111), on the conformational preferences of RPAR using molecular dynamics simulations...

REVIEW
Daniel Hettel, Nima Sharifi
Patients with advanced prostate cancer who receive androgen deprivation therapy (ADT) almost invariably develop castration-resistant disease. The mechanism of resistance is largely based on synthesis of intratumoral androgens from adrenal precursors, requiring enzymatic action of 3β-hydroxysteroid dehydrogenase/Δ5→4 isomerase 1 (3β-HSD1), encoded by HSD3B1. A nucleotide polymorphism (1245A>C) in HSD3B1 results in a protein variant with increased steady-state levels and subsequently increased androgen synthesis from extragonadal precursors...

Sipuleucel-T is the only currently approved immunotherapy for the management of prostate cancer. However, other immunotherapy agents have recently shown activity in prostate cancer and are being developed alone or in combination with other agents. Areas covered: This article provides a review of positive or encouraging clinical trials of agents under development including vaccines, monoclonal antibodies, immune modulators, gene-mediated cytotoxic immunotherapy and chimeric antigen receptor-modified 'designer' T cells in patients with prostate cancer...
