AI Article Synopsis
Article Abstract
Nb rat autonomous prostatic adenocarcinomas were transplanted into several groups of synergeneic Nb rats. Chemotherapy using 5-fluorouracil, methotrexate, Adriamycin, and cyclophosphamide was evaluated. Significance was seen with the use of these agents with varying doses. Cyclophosphamide and 5-fluorouracil treated animals had complete tumor regression whereas Adriamycin and methotrexate treated animals had cessation of tumor volume increase in some groups after chemotherapy; however, neither agent causes complete tumor regression.

Introduction: Prostate cancer guidelines recommend molecular analysis of biomaterial following resistance to first-line systemic therapy in order to identify druggable mutations. We report on our results of molecular analysis of tissue specimens via next generation sequencing (NGS) in men with metastatic castration resistant prostate cancer (mCRPC).
Patients And Methods: In all, 311 mCRPC patients underwent NGS analysis from biopsy samples of progressive metastatic lesions or archival radical prostatectomy specimens.
Prognostic value of intraductal carcinoma subtypes and postoperative radiotherapy for localized prostate cancer.

Background: Intraductal carcinoma of the prostate cancer (IDC-P), as a specific pathological type in prostate cancer which usually implies a poor prognosis. IDC-P morphology can be divided into two subtypes: Pattern 1, sieve like or loose cribriform structures; Pattern 2, solid or dense cribriform structures. The purpose of the study is to identify the impact of IDC-P and its subtypes on the prognosis of patients undergoing post-operative radiotherapy (PORT) after radical prostatectomy (RP) due to localized prostate cancer(PCa).

Background And Objective: It has been shown that androgen receptor pathway inhibitor (ARPIs) treatment for metastatic castration-resistant prostate cancer (mCRPC) improves overall survival rates, but ARPIs appear to be associated with a higher frequency of treatment-related neuroendocrine prostate cancer (t-NEPC). Our aim was to quantify the proportion of prostate adenocarcinoma cases that transition to t-NEPC following ARPI therapy.
Methods: We conducted a comprehensive search of the literature on t-NEPC using databases including MEDLINE and Scopus.

Background: Unlike conventional photon radiotherapy, particle therapy has the advantage of dose distribution. Carbon-ion radiotherapy is also advantageous in terms of biological effectiveness and other radiobiological aspects. These benefits lead to a higher response probability for previously known radioresistant tumor types.

Prostate cancer (PCa) is one of the most common cancers among men worldwide, and robot-assisted radical prostatectomy (RARP) is a widely used treatment for localized PCa. Achieving pentafecta outcomes, which include continence, potency, cancer control, free surgical margins, and no major complications, is a critical measure of surgical success and long-term prognosis. However, predicting these outcomes remains challenging.
