Immunohistochemical Prostate-specific Membrane Antigen (PSMA) Expression Patterns of Primary Prostate Cancer Tissue as a Determining Factor for Prostate Cancer Staging with PSMA Positron Emission Tomography/Computed Tomography.

Background And Objective: In recent studies, prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) has shown accuracy in staging patients diagnosed with prostate cancer. Here, we aim to evaluate the correlation between PSMA immunohistochemical characteristics of prostate cancer (PCa)-positive biopsy cores and whole-mount specimens, and test the predictive role of PSMA expression in biopsy samples for staging PSMA PET/CT.

Methods: A total of 104 patients with high- or intermediate-risk PCa who underwent [68Ga]Ga-PSMA-11 PET/CT before radical prostatectomy were prospectively selected between June 2021 and July 2023.

Impact of Assistant Experience on Perioperative Outcomes of Simple and Radical Laparoscopic Nephrectomy: Does It Really Matter?

: While systematic reviews highlight the advantages of laparoscopic nephrectomy over traditional open surgery, the impact of an assistant's experience on surgical outcomes remains unclear. This study aims to evaluate whether the level of assistant expertise influences laparoscopic nephrectomy outcomes. : Retrospective data from our institutional database were analyzed for patients who underwent laparoscopic nephrectomy between January 2018 and December 2022.
