Prostate tumors are graded by the revised Gleason Score (GS) which is the sum of the two predominant Gleason grades present ranging from 6-10. GS 6 cancer exclusively with Gleason grade 3 is designated as low grade (LG) and correlates with better clinical prognosis for patients. GS >7 cancer with at least one of the Gleason grades 4 and 5 is designated as HG indicate worse prognosis for patients. Current transrectal ultrasound guided prostate biopsies often fail to correctly diagnose HG prostate cancer due to sampling errors...

BACKGROUND: The use of radiolabeled choline as a positron emission tomography (PET) agent for imaging primary tumors in the prostate has been evaluated extensively over the past two decades. There are, however, conflicting reports of its sensitivity and the relationship between choline PET imaging and disease staging is not fully understood. Moreover, relatively few studies have investigated the correlation between tracer uptake and histological tumor grade. This work quantified (18)F-fluorocholine in tumor and healthy prostate tissue using pharmacokinetic modeling and stratified uptake parameters by histology grade...

BACKGROUND: Phase 3 trials have demonstrated a benefit from adjuvant radiation therapy (ART) for men who have adverse factors at radical prostatectomy (RP). However, some patients have a high risk of progression despite ART. The role of systemic therapy with ART in this high-risk group remains to be defined. METHODS: Patients who had either a post-RP prostate-specific antigen (PSA) nadir > 0.2 ng/mL and a Gleason score ≥7 or a PSA nadir ≤0.2 ng/mL, a Gleason score ≥8, and a pathologic tumor (pT) classification ≥ pT3 received 6 months of androgen-deprivation therapy (ADT) plus radiotherapy and 6 cycles of docetaxel...

BACKGROUND: One of the major challenges in prostate cancer (PCa) treatment is distinguishing insignificant PCa from those forms that need active treatment. We evaluated the impact of PSA isoforms on risk stratification in patients with low-risk PCa as well as in active surveillance (AS) candidates who underwent radical prostatectomy. METHODS: A total of 112 patients with biopsy confirmed Gleason score (GS) 6 PCa of four different international institutions were prospectively enrolled in the study...

Rationale:(99m)Tc-trofolastat ((99m)Tc-MIP-1404), a small-molecule inhibitor of prostate-specific membrane antigen (PSMA), shows high potential to detect prostate cancer (PCa) non-invasively using single-photon-emission-computed-tomography (SPECT). We therefore wanted to assess the performance of (99m)Tc-trofolastat SPECT/CT in a phase 2 multi-center, multi-reader prospective study in patients with intermediate- and high-grade PCa, prior to radical prostatectomy and extended pelvic lymph node dissection, with histopathology as gold standard...

BACKGROUND: A positive surgical margin (PSM) following radical prostatectomy (RP) for prostate cancer is associated with increased risk of biochemical recurrence. We sought to examine whether the pathologist is an independent predictor of PSMs. METHODS: We performed a retrospective review of 3,557 men who underwent RP for localized prostate cancer at our institution from 2003 to 2015. We evaluated 29 separate pathologists. Univariate and multivariable logistic regression were used to test variables previously shown to influence PSM rates...

PURPOSE: We have previously demonstrated that transperineal template prostate biopsy (TPTPB) has a significantly higher cancer detection rate compared to transrectal ultrasound guided (TRUS) biopsy in biopsy naive men with a PSA < 20 ng/mL. We, therefore, performed a prospective study to determine whether TPTPB is still superior to TRUS biopsy in the detection of prostate cancer in men with persistently elevated PSA after one previous negative set of TRUS biopsies. MATERIALS AND METHODS: 42 patients with a background of one previous negative set of TRUS biopsy, persistently elevated PSA (but < 20 ng/mL) and benign feeling digital rectal examination (DRE) underwent simultaneous standard 12-core TRUS biopsy and 36-core TPTPB under general anaesthesia...

Purpose Men with localized prostate cancer often are treated with external radiotherapy (RT) over 8 to 9 weeks. Hypofractionated RT is given over a shorter time with larger doses per treatment than standard RT. We hypothesized that hypofractionation versus conventional fractionation is similar in efficacy without increased toxicity. Patients and Methods We conducted a multicenter randomized noninferiority trial in intermediate-risk prostate cancer (T1 to 2a, Gleason score ≤ 6, and prostate-specific antigen [PSA] 10...

AIM: The International Society of Urological Pathology made recommendations for the use of Grade Groups (GG) originally described by Epstein and colleagues over Gleason score (GS) alone in 2014, which was subsequently adopted by the WHO classification in 2016. The majority of studies validating this revision have been in Caucasian populations. We therefore asked whether the new GG system was retrospectively associated with biochemical disease-free survival in a mixed-ethnicity cohort of Asian men...

Purpose: Studies comparing radical prostatectomy (RP) outcomes with those of radiotherapy with or without androgen deprivation therapy (RT±ADT) for prostate cancer (PCa) have yielded conflicting results. Therefore, we used propensity score-matched analysis and competing risk regression analysis to compare cancer-specific mortality (CSM) and other-cause mortality (OCM) between these two treatments. Materials and Methods: The multi-center, Severance Urological Oncology Group registry was utilized to identify 3,028 patients with clinically localized or locally advanced PCa treated by RP (n=2,521) or RT±ADT (n=507) between 2000 and 2016...
