Background: In May 2012 the US Preventive Task Force issued a 'D' recommendation against routine PSA-based early detection of prostate cancer. This recommendation was implemented progressively in our health system. The aim of this study is to define its impact on prostate cancer staging at a tertiary care institution.
Methods: A retrospective analysis was performed from 2012 until 2015 at a single center. We analyzed the total number of biopsies performed per year and the positive biopsy rate. For those patients with positive biopsies we recorded diagnostic PSA, clinical stage, ISUP grade group, nodal involvement and metastatic status at diagnosis.
Results: A total of 1686 biopsies were analyzed. The positive biopsy rate increased from 25% in 2012 to 40% in 2015 (p < 0.05). No change in median PSA was noticed (p = 0.627). The biopsies detected higher ISUP grades (p = 0.000). In addition, newly diagnosed prostate cancer presented a higher clinical stage (p = 0.005), higher metastatic rates (p = 0.03) and a tendency to higher lymph node involvement although not statistically significant (p = 0.09).
Conclusion: After the 2012 recommendation, patients presented a higher probability of a prostate cancer diagnosis, with a more adverse ISUP group, clinical stage and metastatic disease. These results should be taken into consideration to implement a risk adapted strategy for prostate cancer screening.

Transition zone-based prostate-specific antigen density for differentiating clinically significant prostate cancer in PI-RADS score 3 lesions.
Sci Rep

Department of Radiology, The Yancheng School of Clinical Medicine of Nanjing Medical University, Yancheng Third People's Hospital, Yancheng, China.
We intended to investigate the potential of several transitional zone (TZ) volume-related variables for the detection of clinically significant prostate cancer (csPCa) among lesions scored as Prostate Imaging Reporting and Data System (PI-RADS) category 3. Between September 2018 and August 2023, patients who underwent mpMRI examination and scored as PI-RADS 3 were queried from our institution. The diagnostic performances of prostate-specific antigen density (PSAD), TZ-adjusted PSAD (TZPSAD), and TZ-ratio (TZ volume/whole gland prostate volume) were analyzed.

Introduction: In NCCN favorable intermediate-risk (FIR) prostate cancer (PCa) patients treated with radical prostatectomy (RP), we tested the effect of upstaging and upgrading on cancer-specific mortality (CSM).
Methods: Within the SEER database (2010-2021), upstaging (≥pT3a or pN1) and upgrading (ISUP ≥3) rates in FIR RP patients were tabulated. Kaplan-Meier (KM) plots and multivariable Cox-regression models (CRMs) were fitted.
Dosimetric comparison of CyberKnife and conventional linac prostate SBRT plans: analysis of the PACE-B Study.

Purpose: In the PACE-B study, a non-randomised comparison of toxicity outcomes between stereotactic body radiotherapy (SBRT) platforms revealed fewer urinary side-effects with CyberKnife (CK) compared to conventional linac (CL) SBRT. This analysis compares baseline characteristics and planning dosimetry between the CK-SBRT and CL-SBRT cohorts in PACE-B, aiming to provide insight into possible reasons for differing toxicity outcomes between the platforms.
Methods: Dosimetric parameters for the surrogate urethra (SU), contoured urethra, bladder, bladder trigone (BT), and rectum were extracted from available CT planning scans of PACE-B SBRT patients.

Prostate cancer (PCa) is the most common malignant tumor of the male reproductive system. In this study, we establish an induced pluripotent stem cell (iPSC) line from a male diagnosed with PC. of This iPSCs line was generated from the peripheral blood mononuclear cells (PBMCs) using a non-integrated Sendai virus.

Aim: We aimed to evaluate whether preoperative bladder neck thickness (BNT) measured by magnetic resonance imaging (MRI) can guide surgical decisions in benign prostatic hyperplasia (BPH) and primary bladder neck obstruction (PBNO) patients with a small volume (≤30 mL).
Materials And Methods: The clinical data of 403 patients were retrospectively collected. The Kappa consistency test was used to compare subjective (IPSS-voiding) and objective (Qmax) postoperative outcomes.
