The real prevalence and clinical courses of non-metastatic castration-resistant prostate cancer: a retrospective single-institutional study.

Background: Non-metastatic castration-resistant prostate cancer (PCa) has become clinically important in PCa management, with treatments aiming to delay metastasis. However, limited data exist on its prevalence and patient characteristics in real-world settings.

Methods: We retrospectively investigated the clinical records of 1929 patients who were treated for localized PCa between 2005 and 2018.

Impact of aspirin on biochemical recurrence of prostate cancer after robot assisted radical prostatectomy in a multicenter retrospective cohort study.

This study evaluated the impact of aspirin on the biochemical recurrence (BCR) rate following robot-assisted radical prostatectomy (RARP) in patients. A database search identified patients who underwent RARP for pT2-3N0M0 disease at any of 25 centers between 2011 and 2022, categorized into aspirin (n = 350) and control groups (n = 5857). Adjustment by 1:1 propensity score matching (PSM) and Mahalanobis distance matching (MDM) created 350 matched pairs.

Clinical Utility of Serial Circulating Tumor DNA Analysis as a Minimally Invasive Biomarker in Advanced Urothelial Cancer.

Purpose: Circulating tumor DNA (ctDNA) analysis is an alternative to tissue biopsy for genotyping in various cancers. We aimed to establish a plasma ctDNA sequencing assay, then evaluate its clinical utility in advanced urothelial cancer (UC).

Materials And Methods: This study included 82 patients with muscle-invasive or metastatic UC.

[Clinical Study of Lymph Node Dissection in Robot-Assisted Radical Prostatectomy for High-Risk Prostate Cancer].

We retrospectively analyzed the regions and perioperative outcomes associated with lymph node dissection in patients with prostate cancer. Of 543 patients who underwent robot-assisted radical prostatectomy for prostate cancer with or without lymph node dissection according to the modified D'Amico criteria, 333 (61.3%), 128 (23.

Impact of neurovascular bundle preservation on biochemical recurrence after robot-assisted radical prostatectomy for high-risk prostate cancer.

Purpose: To evaluate functional and oncological outcomes in patients who underwent unilateral or bilateral nerve-sparing (NS) robot-assisted radical prostatectomy (RARP) for high-risk prostate cancer.

Methods: The cohort comprised 2683 patients with clinical stage T1-4, N0M0 high-risk prostate cancer who underwent RARP in Japanese tertiary care centers from August 2011 to April 2023. High risk was defined using the European Association of Urology risk stratification criteria.
