PURPOSE OF REVIEW: This article intends to review biomarkers derived from blood, urine, and tissue that can aid in the diagnosis of prostate cancer (PCa). RECENT FINDINGS: PCa screening requires tools that complement prostate-specific antigen (PSA) with a higher specificity for clinically significant disease. Novel blood biomarkers, such as the Prostate Health Index (phi) and 4Kscore, utilize isoforms of PSA to more accurately predict high-grade PCa than traditional tools such as PSA and the percentage free-to-total PSA...

PURPOSE: The objective of this study was to compare the prognostic effect of time to prostate-specific antigen (PSA) nadir (TTPN) after treatment with abiraterone acetate (AA) and enzalutamide (Enz) in patients with docetaxel-naïve, metastatic castration-resistant prostate cancer (mCRPC). METHODS: This study included a total of 297 consecutive patients with mCRPC, of whom 125 and 172 received AA and Enz, respectively, without previous treatment with docetaxel and subsequently achieved any degree of PSA reduction after the administration of either agent...

OBJECTIVE: To evaluate the potential role of neutrophil-to-lymphocyte ratio (NLR) with therapeutic response in patients who were treated with docetaxel for mCRPC. MATERIALS AND METHODS: We retrospectively analyzed the clinical data from 111 consecutive patients who were treated with docetaxel for mCRPC from 2009 to 2016 in a single center from Northwestern China. Pretreatment baseline and follow-up data including age, PSA response, Gleason score, and cycle number were reviewed, and multivariable Cox regression models and Kaplan-Meier analysis were used to predict overall survival (OS) and progression-free survival (PFS)...

Ferritin is highly expressed in many cancer types. Although a few studies have reported an association between high serum ferritin levels and an increased risk of prostate cancer, the results are inconsistent. Therefore, we performed a large case-control study consisting of 2002 prostate cancer patients and 951 control patients with benign prostatic hyperplasia (BPH). We found that high ferritin levels were positively associated with increased serum prostate-specific antigen (PSA) levels and prostate cancer risk; each 100 ng/ml increase in serum ferritin increased the odds ratio (OR) by 1...

MATERIALS AND METHODS: A total of 22 men undergoing TRUSB of the prostate were enrolled in the study. Patients with abnormal digital rectal examination and/or total prostate specific antigen (PSA) over 4ng/mL underwent TRUSB with 12 cores...

INTRODUCTION: To assess predictive value of new tumor markers, precursor of prostate specific antigen (p2PSA) and its derivates-%p2PSA and prostate health index (PHI) in detection of patients with indolent and aggressive prostate cancer (PC) in a subcohort of man whose total PSA ranged from 2 to 10ng/mL. MATERIALS AND METHODS: This cross-sectional study included 129 consecutive male patients aged over 50 years, with no previous history of PC and with normal digital rectal examination findings, but with serum PSA in interval between 2 and 10ng/mL...

INTRODUCTION: The use of nomograms which include the PSA may improve the predictive power of obtaining a prostate biopsy (PB) positive for cancer. We compare the use of three on-line nomagrams with the detection of primary malignant circulating prostate cells (CPCs) to predict the results of an initial PB in men with suspicion of prostate cancer. METHODS AND PATIENTS: Consecutive men with suspicion of prostate cancer underwent a 12 core TRUS prostate biopsy; age, total serum PSA, percent free PSA, family history, ethnic origin and prostate ultrasound results were used for risk assessment using the online nomograms...

BACKGROUND: The prognostic role of preoperative serum lipid levels in patients undergoing radical prostatectomy (RP) for clinically localized prostate cancer (PCa) is unclear. The aim of the present study was to investigate preoperative serum lipid levels in patients with clinically localized PCa undergoing RP and their association with clinicopathological features and oncological outcome. METHODS: Preoperative lipid levels (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) and statin use from consecutive patients with clinically localized PCa undergoing RP in a tertiary referral center between 2008 and 2015 were recorded and patients were followed prospectively...

PURPOSE: To assess the efficacy of robotic-assisted laparoscopic sentinel lymph node (SLN) dissection (SLND) to select those patients with prostate cancer (PCa) who would benefit from additional pelvic external beam radiation therapy and long-term androgen deprivation therapy (ADT). METHODS AND MATERIALS: Radioisotope-guided SLND was performed in 224 clinically node-negative patients scheduled to undergo external beam radiation therapy. Patients with histologically positive SLNs (pN1) were also offered radiation therapy to the pelvic lymph nodes, combined with 3 years of ADT...

AIM: To analyze prostate cancer (PCa) incidence, clinical significance, and recurrence in 213 patients who underwent radical cystectomy (RC) for advanced bladder cancer (BC). PATIENTS AND METHODS: We conducted a 10-year retrospective analysis of a single-center database comprising the effect of PCa in RC specimens. RESULTS: In total, 113/213 male patients (53.1%) had PCa in the RC specimen. Patients׳ age, prostate-specific antigen (PSA), and also free PSA% were significant predictors for PCa...

Prostate cancer is the second most frequently diagnosed cancer in men worldwide. Currently prostate specific antigen (PSA) serum concentration is the most used prostate cancer marker, but it only shows limited specificity. Because PSA glycosylation is altered by prostate cancer, detecting glycosylation changes could increase PSA specificity as a prostate cancer marker. Changes in PSA glycosylation can modify its electrophoretic- behavior and techniques such as capillary zone electrophoresis (CZE) and two-dimensional electrophoresis (2-DE) could be applied to detect changes in PSA glycosylation...

OBJECTIVE: Prostate specific antigen (PSA), used for the early diagnosis of prostate cancer (PCa), is one of the best tumour markers known so far. However, in situations when PSA is between 2-10 ng/mL, which is named as grey zone, PSA falls short of distinguishing benign prostate diseases from PCa. On the other hand, it was demonstrated in many previous studies that microRNA (miRNA) could be a marker for cancer. Therefore, in this study, it was aimed to enhance the diagnostic power of PSA, especially with grey zone patients, by the use of miRNA...

BACKGROUND: The risk stratification currently applied prior to curative treatment for localized prostate cancer (PC) does not take into account comorbidity or age. Therefore, we investigated the impact of comorbidity on overall survival (OS) in PC patients treated with external beam radiotherapy (EBRT) and high-dose rate (HDR) brachytherapy boost. MATERIAL AND METHODS: At a single center, 611 consecutive patients diagnosed with localized PC from 1998 to 2004 underwent definitive EBRT (50 Gy) and HDR brachytherapy boosts (2 × 10 Gy) combined with neoadjuvant total androgen blockade...

In addition, to determine the success of (111) In-PSMA-RGS with regard to postoperative prostate-specific antigen (PSA) responses, PCa-specific treatment-free survival rates and postoperative complication rates...

BACKGROUND AND OBJECTIVES: Recently, we described an inverse association between cranberry supplementation and serum prostate specific antigen (PSA) in patients with negative biopsy for prostate cancer (PCa) and chronic nonbacterial prostatitis. This double blind placebo controlled study evaluates the effects of cranberry consumption on PSA values and other markers in men with PCa before radical prostatectomy. METHODS: Prior to surgery, 64 patients with prostate cancer were randomized to a cranberry or placebo group...

BACKGROUND: Non-prostatic bed recurrence of prostate cancer (PCa) is usually treated with androgen deprivation therapy (ADT). We analyzed the impact of salvage extended lymph node dissection (sLND) on cancer control in patients with rising PSA and lymph node (LN) metastases. METHODS: Between 2009 and 2016 we performed sLND in 87 patients with biochemical recurrence (BCR) and positive LNs on (18)FEC and (68)Ga-PSMA positron emission tomography/X-ray computer tomography (PET/CT) after primary treatment (PT) of PCa...
