Article Synopsis
  • Conducted a detailed proteomic and phosphoproteomic analysis of prostate cancer tissues from 41 Chinese patients, building on previous genomic research.
  • Identified three distinct proteomic subtypes that differ in molecular features and clinical outcomes, each with unique characteristics related to metabolism, proliferation, and immune response.
  • Demonstrated that specific protein combinations are effective biomarkers for predicting recurrence, while highlighting the role of SRSF1 phosphorylation in cancer cell malignancy, which could inform personalized treatment approaches.

Article Synopsis
  • Prostate cancer (PCa) is the most common cancer in men, but there are few reliable ways to predict outcomes and guide treatments.
  • Researchers conducted proteomic profiling on 918 tissue samples from 306 Chinese PCa patients, identifying over 10,000 proteins and classifying PCa into three distinct molecular subtypes.
  • They developed a 16-protein panel that predicts biochemical recurrence (BCR) in PCa patients better than existing methods, and found that knocking out two proteins from this panel may inhibit cancer cell growth and spread, presenting potential new treatment strategies.

Objective: Based on post-operative PSA at 6th week (PSA) after radical prostatectomy to establish an optimal model for predicting natural biochemical recurrence (BCR).

Methods: A total of 742 patients with post-operative PSA from PC-follow database, between January 2003 and October 2022, were included. All the patients had not received any hormone therapy and radiotherapy before operation and BCR.

Purpose: Our study was to determine whether immediate androgen deprivation therapy (ADT) plus radiotherapy (RT) extends survival in men with node-positive prostate cancer (PCa) after radical prostatectomy (RP) compared with those who received ADT alone.

Methods: A total of 99 consecutive patients with pathological positive lymph nodes (pN1) PCa were included in this study to receive immediate ADT plus RT (n = 70) or to receive immediate ADT alone (n = 29). The primary endpoint was castration-resistant prostate cancer (CRPC) free survival; the secondary endpoints were distant metastasis-free survival.

Transgelin (TAGLN, also named SM22) is an actin-associated protein and affects dynamics of actin filaments. Deregulation of TAGLN contributes to the development of different cancers, and it is commonly considered to be a tumor suppressor. TAGLN is usually downregulated in prostate cancer; however, the detailed functions of TAGLN in prostate cancer and how TAGLN is regulated remains unclear.

The inability to remove an indwelling urethral catheter in a postrobot-assisted laparoscopic radical prostatectomy (RALP) patient constitutes a serious problem to the urologist. If the proper deflation of the catheter balloon is not observed, forcible extraction can lead to devastating consequences such as urethral disruption and subsequent stricture formation. A 60-year-old male patient developed lower urinary-tract symptoms 20 months after robotic prostatectomy for early prostate cancer.

Objectives: To summarize the experience of the first 500 robot-assisted laparoscopic radical prostatectomy (RALP) cases by one surgeon and analyze the influencing factors of functional and oncological outcomes.

Methods: Between April 2012 and October 2017, 500 patients who underwent RALP were included and divided sequentially into five equal groups. Patients' preoperative, perioperative and postoperative outcomes were analyzed and evaluated, and the Kruskal-Wallis test was used to analyze and compare the effect of surgeon experience by case.

Background: The role of local treatment in oligometastatic prostate cancer (PCa) is gaining interest with the oligometastases hypothesis proposed and the improvement of various surgical methods and techniques. This study aimed to compare the short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy (RALP) for oligometastatic prostate cancer (OPC) vs. localized PCa using propensity score matching.

Purpose: In this study, we addressed the underlying mechanisms for the association between enzalutamide (ENZ) treatment and neuroendocrine prostate cancer (NEPC), and the critical involvement of MYCN, and loss of RB1 function in neuroendocrine differentiation (NED) of prostatic epithelial cells, and the development of NEPC. We further sought to determine whether PARP inhibition could suppress NEPC, and to identify molecular determinants of this therapeutic activity.

Experimental Design: We used a novel prostate cancer patient-derived xenograft (PDX) treatment model, prostatic adenocarcinoma and NEPC cell lines, an NEPC organoid line, and NEPC xenograft models to address the mechanistic basis of ENZ-induced NED, and to analyze suppression of NED and NEPC growth by PARP inhibition.

The prostate specific antigen (PSA) test is widely used for early diagnosis of prostate cancer (PCa). However, its limited sensitivity has led to over-diagnosis and over-treatment of PCa. Glycosylation alteration is a common phenomenon in cancer development.

As a newly discovered tumor suppressor, the potential function of PAQR3 in human prostate cancer has not been demonstrated. In this study, we report that PAQR3 is able to inhibit the growth and migration of human prostate cancer cells both and . Overexpression of PAQR3 inhibits the proliferation of PC3 and DU145 cells by both MTT and colony formation assays.

Objective: To investigate the learning curve of robotic-assisted laparoscopic radical prostatectomy (RALP) and analyze whether a surgeon's prior surgical experience has effects on the surgery.

Patients And Methods: From April 2012 to August 2015, 3 surgeons performed RALP on 355 consecutive patients with prostate cancer. Among these cases, 184 were by surgeon A with prior open experiences, 92 by surgeon B with both open and laparoscopic experiences, and 79 by surgeon C with laparoscopic experiences only.
