Utemeljitev: Zaradi oportunističnega presejanja odkrijemo veliko primerov raka prostate (RP) z ugodnejšo prognozo. Mednje spadajo bolniki z ISUP skupino po Gleasonu 1 in 2 (GG1 in GG2). Kljub dobri prognozi in možnosti aktivnega opazovanja pri teh bolnikih se bo pri nekaterih po radikalni prostatektomiji (RRP) razvila biokemična ponovitev (BKR) ali...

Globally, prostate cancer (PCa) is the second most preponderant cancer in men. It contributes to the high mortality-to-incidence ratio reported in West Africa and Asia largely due to low screening. The mortality risk is determined or predicted based on the prevalence of high-risk or aggressive PCa using a scoring or grading system such as Gleason s...

Introduction The aim of this article was to evaluate the effectiveness of the Gleason grade groups (GGG) system on a group of Argentinian patients with prostate cancer (PC) who underwent radical prostatectomy (RP). Material and methods We retrospectively studied 262 patients who underwent RP between 1996 and 2014. To determine the performance and v...

The present study investigated the concordance between Gleason scores assigned to prostate biopsy specimens by outside pathologists and a urological pathology expert, and determined the risk of upgrading between opinion-matched Gleason grade group (GGG) 1 biopsy specimens and radical prostatectomy specimens. Between January 2012 and May 2018, 733 p...

Recently, a new prostate cancer (PC) grading system was introduced, where Gleason score (GS) 7 was divided into 3 + 4 = 7 and 4 + 3 = 7 due to the different prognoses associated with each tumor type. However, whether downgrading or upgrading from needle biopsy (NB) to radical prostatectomy (RP) affects oncologic outcomes is currently unknown. Herei...

BackgroundAccurate grading at the time of diagnosis if fundamental to risk stratification and treatment decision making in patients with prostate cancer. Whilst previous studies have demonstrated significant pathological upgrading and downgrading following radical prostatectomy (RP), these were based on historical cohorts and do not reflect contemp...

To investigate the performance of diffusion kurtosis imaging (DKI) and diffusion tensor imaging (DTI) in discriminating benign tissue, low- and high-grade prostate adenocarcinoma (PCa). Forty-eight patients with biopsy-proven PCa of different Gleason grade (GG), who provided written informed consent, were enrolled. All subjects underwent 3T DWI exa...

Background and objectives : Prostate cancer (PCa) is a common malignancy in males and has a relatively slower progression than other cancers. Our goal was to evaluate the clinical role of SPARC (secreted protein acidic and cysteine rich, osteonectin), cwcv, and kazal-like domains’ proteoglycan 1 (SPOCK1) in PCa. Materials and Methods : SPOCK1 expre...

To automatically assess the aggressiveness of prostate cancer (PCa) lesions using zonal-specific image features extracted from diffusion weighted imaging (DWI) and T2W MRI. Region of interest was extracted from DWI (peripheral zone) and T2W MRI (transitional zone and anterior fibromuscular stroma) around the center of 112 PCa lesions from 99 patien...

Prognosis for intermediate-risk prostate cancer (PCa) remains variable; therefore, we aimed to investigate high-risk factors for biochemical recurrence (BCR), and intermediate-risk PCa using radical prostatectomy to identify patients having equivalent BCR-free survival rates when compared to high-risk PCa. A total of 441 medical records were analyz...
