Prostate cancer is the most common solid tumor malignancy in men worldwide. Treatment with surgery and radiation can be curative in organ-confined disease. Unfortunately, about one third of men develop biochemically recurrent disease based only on rising prostate-specific antigen (PSA) in the absence of visible disease on conventional imaging. For these patients with biochemical recurrent prostate cancer, there is no uniform guideline for subsequent management. Based on available data, it seems prudent that biochemical recurrent prostate cancer should initially be evaluated for salvage radiation or prostatectomy, with curative intent...

The Italian national health system provides screening to detect breast, colorecatal and cervical cancers, however, population adherence is not as high as expected. Smartphones and their applications (apps) could be used as a tool to communicate with the population and to help improve adherence. The aim of this study was to analyze the features and functions of smartphone applications aimed at secondary prevention of oncological diseases. In February 2016, we reviewed online app stores, using specific key-words, to search for available apps for cancer screening...

The incidence of cancer is increasing worldwide and metastatic disease, through the spread of circulating tumor cells (CTCs), is responsible for the majority of the cancer deaths. Accurate monitoring of CTC levels in blood provides clinical information supporting therapeutic decision making, and improved methods for CTC enumeration are asked for. Microfluidics has been extensively used for this purpose but most methods require several post-separation processing steps including concentration of the sample before analysis...

Jie Li, Qi-Qi Mao
Previous studies regarding the relationship between legume intake and risk of prostate cancer have reported inconsistent results. We conducted a meta-analysis of prospective cohort studies to summarize evidence on this association. A systematic literature search of articles published through June 2016 was performed using PubMed and Web of Science databases. The combined relative risk (RR) with its 95% confidence interval (CI) for the highest versus the lowest intake of legumes was calculated with a random-effects model...

BACKGROUND: Patients with prostate cancer and their providers face uncertainty as they consider adjuvant radiotherapy (ART) or salvage radiotherapy (SRT) after undergoing radical prostatectomy. The authors prospectively evaluated the impact of the Decipher test, which predicts metastasis risk after radical prostatectomy, on decision making for ART and SRT. METHODS: A total of 150 patients who were considering ART and 115 who were considering SRT were enrolled. Providers submitted a management recommendation before processing the Decipher test and again at the time of receipt of the test results...

It is still unclear whether persistent organic pollutants (POPs) exposure increases the prostate cancer incidence risk. This prospective cohort study evaluated the associations between serum POPs concentrations and prostate cancer risk. Within a case-cohort study, we identified 110 people diagnosed with prostate cancer and randomly selected 256 sub-cohort participants without prostate cancer. Serum concentrations of 32 polychlorinated biphenyl (PCB) congeners and 19 organochlorine pesticides (OCPs) were measured...

Prostate Specific Antigen (PSA) is the most commonly used serum marker for prostate cancer (PCa), although it is not specific and sensitive enough to allow the differential diagnosis of the more aggressive tumors. For that, new diagnostic methods are being developed, such as PCA-3, PSA isoforms that have resulted in the 4K score or the Prostate Health Index (PHI), and PSA glycoforms. In the present study, we have compared the PHI with our recently developed PSA glycoform assay, based on the determination of the α2,3-sialic acid percentage of serum PSA (% α2,3-SA), in a cohort of 79 patients, which include 50 PCa of different grades and 29 benign prostate hyperplasia (BPH) patients...

OBJECTIVE: To investigate if curative prostate cancer (PCa) treatment was received less often by men with both PCa and Type 2 diabetes mellitus (T2DM), as little is known about if a diagnosis of T2DM influences receipt of curative treatment in men with localised PCa. SUBJECTS/PATIENTS AND METHODS: Data from Prostate Cancer database Sweden (PCBaSe) from men with T2DM and PCa (n=2,210) was used to compare with those with PCa only (n=23,071). All men had intermediate (T1-2, Gleason score 7 and/or PSA 10-20 ng/ml) or high risk (T3 and/or Gleason score 8-10 and/or PSA 20-50 ng/ml) localised PCa diagnosed between 1(st) January 2006 and 31(st) December 2014...

BACKGROUND: Ethanol in alcoholic beverages is a known carcinogen, but its association with aggressive prostate cancer (APC) is uncertain. Recent studies have shown a modest increase in risk of APC associated with heavy alcohol intake while association for beverage types remain inconsistent. METHODS: Using a case-control design and self-administered questionnaire, we examined the association between APC (high grade and/or advanced stage) and frequency and quantity of alcohol intake 2 years prior to enrolment...

BACKGROUND: There is increasing low-quality evidence rationalizing the use of radical therapy for men at high risk of disseminated prostate cancer. OBJECTIVE: To investigate, using high-quality epidemiologic data, whether initial radical therapy in men at high risk of disseminated prostate cancer improves survival. DESIGN, SETTING, AND PARTICIPANTS: An observational population-based Swedish study from 1996 to 2010 of men at high risk of disseminated prostate cancer (prostate-specific antigen [PSA] >50) initially treated by radical therapy (radiation therapy [n=630] or radical prostatectomy [n=120]) or androgen deprivation therapy (n=17 602), and followed for up to 15 yr...

BACKGROUND: High-grade prostatic intraepithelial neoplasia (HGPIN) is the precursor or premalignant form of prostate cancer. At least 30% patients with a confirmed HGPIN will develop prostate cancer within 1 year after repeated biopsy. HGPIN patients are the appropriate at-risk population for chemoprevention strategies investigation against prostate cancer. However the commonly used chemoprevention agents that targeted on hormonal imbalance or lifestyle-related factors showed varied results in HGPIN patients...

BACKGROUND: Patients with previous malignancies could be at increased risk of non-small cell lung cancer (NSCLC). However, the extent of the risk is unknown for many cancer types; thus, it is unclear who might benefit from screening. MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results data set from 1992 to 2012 was used to identify patients with previous malignancies who received a diagnosis of NSCLC ≥ 6 months after their initial cancer diagnosis...

BACKGROUND: Preoperative assessment of the risk of lymph node invasion (LNI) is mandatory to identify prostate cancer (PCa) patients who should receive an extended pelvic lymph node dissection (ePLND). OBJECTIVE: To update a nomogram predicting LNI in contemporary PCa patients with detailed biopsy reports. DESIGN, SETTING, AND PARTICIPANTS: Overall, 681 patients with detailed biopsy information, evaluated by a high-volume uropathologist, treated with radical prostatectomy and ePLND between 2011 and 2016 were identified...

PURPOSE: In proton radiation therapy, a relative biological effectiveness (RBE) equal to 1.1 is currently assumed, although biological experiments show that it is not constant. The purpose of this study was to quantify the uncertainties of a published biological model and explore their impact on variable RBE treatment plan (TP) optimization. METHODS: Two patient cases with a high and a low (α/β)x tumor were investigated. Firstly, intensity modulated proton therapy TPs assuming constant RBE were derived, and subsequently the variable RBE weighted dose (RWD), including the uncertainty originating in the fit to the experimental data and the uncertainty of the (α/β)x, were calculated...

BACKGROUND: The use of prostate cancer screening tools that take into account relevant prebiopsy information (ie, risk calculators) is recommended as a way of determining the risk of cancer and the subsequent need for a prostate biopsy. This has the potential to limit prostate cancer overdiagnosis and subsequent overtreatment. mHealth apps are gaining traction in urological practice and are used by both practitioners and patients for a variety of purposes. OBJECTIVE: The impetus of the study was to design, develop, and assess a smartphone app for prostate cancer screening, based on the Rotterdam Prostate Cancer Risk Calculator (RPCRC)...

REVIEW

Obesity is defined as abnormal or excessive fat accumulation. Chronic inflammation in fat influences the development of obesity-related diseases. Many reports state that obesity increases the risk of morbidity in many diseases, including hypertension, dyslipidemia, type 2 diabetes, coronary heart disease, stroke, sleep apnea, and breast, prostate and colon cancers, leading to increased mortality. Obesity is also associated with chronic neuropathologic conditions such as depression and Alzheimer's disease. However, there is strong evidence that weight loss reduces these risks, by limiting blood pressure and improving levels of serum triglycerides, total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol...
