OBJECTIVE: The approach for treating high-risk prostate cancer still presents different unresolved issues. We report the safety and efficacy of a radiation therapy strategy based on the combination of moderate hypofractioned simultaneous integrated boost (SIB) and Image Guidance. MATERIALS AND METHODS: In this phase II trial of patients with high-risk prostate cancer, Image Guided SIB-IMRT plans (Simultaneous Intensity Modulated - Intensity Modulated Radiotherapy) were delivered between 2009 and 2012...

BACKGROUND: Early biochemical recurrence (eBCR) after radical prostatectomy (RP) heralds poor oncological outcomes and may be prevented with adjuvant radiation (aRT). METHODS: We developed a contemporary eBCR nomogram in 13 797 RP patients from Hamburg (2005-2016) and externally validated it in 5952 RP patients from Vienna. Receiver operating characteristics-derived area under the curve (AUC), Heagerty's C-index, and decision curve analysis (DCA) were used to quantify model accuracy and to compare the current tool with the Walz nomogram, the online Memorial Sloan Kettering Cancer Center (MSKCC) nomogram and the post-surgical Cancer of the Prostate Risk Assesment (CAPRA-S)...

BACKGROUND: The Briganti updated nomogram (BN) is the most popular predictive model aiming to predict the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa), but it lacks information obtained by preoperative imaging. The primary aim of the study was to evaluate the role of multiparametric prostate magnetic resonance imaging (mp-MRI) in the indication to perform pelvic lymph nodes dissection (PLND) or not in patients with risk of LNI according to BN below 5%. METHODS: Since March 2012 and September 2016, 310 patients who underwent a preoperative mp-MRI for staging purpose and subsequent robot-assisted extended PLND (RAEPLND) were retrospectively evaluated...

Glycosylation is recognized as one of the most common modifications on proteins. Recent studies have shown that aberrant expression of α (1,6) fucosyltransferase (FUT8), which catalyzes the transfer of fucose from GDP-fucose to core-GlcNAc of the N-linked glycoproteins, modulates cellular behavior that could lead to the development of aggressive prostate cancer. While the relationship between the abnormal expression of FUT8 and glycoprotein fucosylation in different prostate cancer cells has been demonstrated, there is no evidence that shows dysregulated fucosylation might be involved in prostate cancer progression from androgen-dependent to castration-resistant prostate cancer...

BACKGROUND: To examine clinical characteristics, treatment modalities and oncological outcomes of prostate cancer (PCa) according to young (≤50) vs. old age. METHODS: Of 407,599 men with primary adenocarcinoma of the prostate within the Surveillance, Epidemiology and End Results (SEER)-database (2004 to 2013), 18,387 were aged ≤50 years (4.5%). Time trends, cumulative incidence, and competing risks regression (CRR) analyses tested for differences between young and old patients...

BACKGROUND: Prostate cancer (PCa) is the second most frequently diagnosed cancer among men worldwide. Many epidemiological studies have found an inverse association between increased tomato consumption and PCa risk. This study aims to determine the associations between consumption of various types of tomato products and PCa risk and to investigate potential dose-response relationships. METHODS: We conducted a systematic review and dose-response meta-analysis of dietary tomato in relation to PCa...

BACKGROUND: We tested whether tissue-based analysis of p53 and PTEN genomic status in primary tumors is predictive for subsequent sensitivity to abiraterone and enzalutamide in castration-resistant prostate cancer (CRPC). METHODS: We performed a retrospective analysis of 309 consecutive patients with CRPC treated with abiraterone or enzalutamide. Of these, 101 men (33%) had available primary tumor tissue for analysis. We screened for deleterious TP53 missense mutations and PTEN deletions using genetically validated immunohistochemical assays for nuclear accumulation of p53 protein and PTEN protein loss, with sequencing confirmation of TP53 mutations in a subset...

BACKGROUND: Prostate cancer (PCa) is a leading cause of mortality and genetic factors can influence tumour aggressiveness. Several germline variants have been associated with PCa-specific mortality (PCSM), but further replication evidence is needed. METHODS: Twenty-two previously identified PCSM-associated genetic variants were genotyped in seven PCa cohorts (12,082 patients; 1544 PCa deaths). For each cohort, Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals for risk of PCSM associated with each variant...

BACKGROUND: Treatment options for metastatic castration-resistant prostate cancer (mCRPC) have expanded in recent years and include cytotoxic agents (e.g., docetaxel and cabazitaxel), immunotherapy (e.g., sipuleucel-T), oral hormonal therapies targeting the androgen receptor axis (e.g., enzalutamide and abiraterone), and targeted alpha therapy (e.g., radium-223 dichloride (radium-223)). Although treatment guidelines have been updated to reflect the availability of new agents, it is not easy to apply them in daily clinical practice because recommendations vary depending on patient comorbidities and disease characteristics...

BACKGROUND: We performed a systematic review and meta-analysis to determine the prevalence and predictors of urethral stricture development post radiation therapy (RT) for prostate cancer (PCa). METHODS: Published articles in PubMed/Medline, Cochrane, and Embase databases from January 2000 to April 2016 were queried. Inclusion criteria were any study that reported the prevalence of urethral strictures following external beam radiation therapy (EBRT), brachytherapy (BT), or both as a primary treatment for PCa...

BACKGROUND: Epidemiologic evidence for a serum cholesterol-prostate cancer link is mixed. Prostate-specific antigen (PSA) is positively correlated with cholesterol, potentially increasing PSA-driven biopsy recommendations in men with high cholesterol, though biopsy compliance may be lower in men with comorbid conditions. These potential biases may affect PSA-driven biopsy rates and subsequent prostate cancer detection in men with high serum cholesterol. Our objective was to test the association between serum cholesterol and prostate cancer risk in men receiving PSA independent, study-mandated prostate biopsies...

BACKGROUND: Convective radiofrequency water vapor thermal therapy with the Rezūm system is a relatively new treatment for benign prostatic hyperplasia (BPH). We present results from a single surgeon in an office setting. METHODS: A retrospective review of 129 patients from a single surgeon who underwent the Rezūm procedure was performed. All patients were at least 4 months out from treatment. International prostate symptom scores (IPSS), maximum flow rates (Qmax), residual urine volumes, medication usage, and adverse events were monitored...

BACKGROUND: Metabolic syndrome and obesity are linked with hyperuricemia, and it has also been proposed that oxidative stress associated with hyperuricemia may promote benign prostatic hyperplasia (BPH). However, it is currently unknown whether use of antihyperuricemic medication is associated with risk of developing BPH. We studied the association between BPH and use of antihyperuricemic allopurinol in a Finnish population-based cohort. METHODS: The study cohort consisted of 74,754 men originally identified for the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC)...

BACKGROUND: Until 2015, androgen deprivation therapy (ADT) alone was the standard-of-care for metastatic hormone-sensitive prostate cancer (mHSPC). In 2015, the CHAARTED and STAMPEDE-Docetaxel studies demonstrated marked survival benefit with the addition of docetaxel to ADT in the mHSPC setting, leading to a change in the standard-of-care for mHSPC. The recent LATITUDE and STAMPEDE-Abiraterone trials showed similar substantial improvement in survival with the addition of abiraterone plus prednisone to ADT in this space...

BACKGROUND: Patients with high-risk prostate cancer have an increased likelihood of experiencing a relapse following radical prostatectomy (RP). We previously conducted three neoadjuvant androgen-deprivation therapy (ADT) trials prior to RP in unfavorable intermediate and high-risk disease. METHODS: In this analysis, we report on the post-RP outcomes of a subset of patients enrolled on these studies. We conducted a pooled analysis of patients with available follow-up data treated on three neoadjuvant trials at three institutions...

BACKGROUND: Screening for prostate cancer using prostate-specific antigen (PSA) alone leads to un-necessary biopsying and overdiagnosis. PSA density is easily accessible, but early evidence on its use for biopsy decisions was conflicting and use of PSA density is not commonly recommended in guidelines. METHODS: We analyzed biopsy outcomes in 5291 men in the population-based STHLM3 study with PSA ≥ 3 ng/ml and ultrasound-guided prostate volume measurements by using percentages and regression models...

BACKGROUND: Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) may have a preventive effect against prostate cancer. However, evidence is limited and still controversial, especially considering non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs). METHODS: Swedish nationwide population-based cohort study including all long-term (≥180 days) adult male users of aspirin (n = 419,931) or NSAIDs (n = 223,437) followed from the first dispense date until the first cancer diagnosis, death or 31 December 2012, whichever occurred first...
