Prostate ductal adenocarcinoma with MLH1 copy number loss, microsatellite instability high and BRCA2 mutation.

Mismatch repair deficiency (MMRd) or microsatellite instability high (MSI-H) is rare in prostate cancer and more frequently observed in cases with ductal histology. MLH1 copy number loss is extremely rare in MMRd tumors. Herein, we describe a case of prostate ductal adenocarcinoma with MLH1 copy number loss, microsatellite instability high and BRCA2 mutation could derive benefit from immunotherapy plus ADT.

Patient-reported outcomes of rezvilutamide versus bicalutamide in combination with androgen deprivation therapy in high-volume metastatic hormone-sensitive prostate cancer patients (CHART): a randomized, phase 3 study.

The randomized phase 3 CHART trial (NCT03520478) revealed that rezvilutamide (REZ) plus androgen deprivation therapy (ADT) in high-volume, metastatic, hormone-sensitive prostate cancer (mHSPC) significantly enhanced radiographic progression-free and overall survival than bicalutamide (BIC)-ADT. Accordingly, we examined patient-reported outcomes (PROs) results, which were exploratory endpoints in the CHART trial. The patients were randomly allocated to receive REZ-ADT or BIC-ADT in a 1:1 ratio.

Development of machine learning prognostic models for overall survival of prostate cancer patients with lymph node-positive.

Prostate cancer (PCa) patients with lymph node involvement (LNI) constitute a single-risk group with varied prognoses. Existing studies on this group have focused solely on those who underwent prostatectomy (RP), using statistical models to predict prognosis. This study aimed to develop an easily accessible individual survival prediction tool based on multiple machine learning (ML) algorithms to predict survival probability for PCa patients with LNI.

DKK1 Ameliorates Myofibroblast Differentiation in Urethral Fibrosis in Vivo and in Vitro by Regulating the Canonical Wnt Pathway.

Urethral stricture is a common disorder of the lower urinary tract in men. A complex network of pathways and interactions are involved in the pathogenesis of urethral fibrosis. However, the mechanisms underlying urethral fibrosis remain poorly understood.

Circular RNA CSPP1 motivates renal cell carcinoma carcinogenesis and the Warburg effect by targeting RAC1 through microRNA-493-5p.

Circular RNAs (circRNAs) take on regulatory roles in renal cell carcinoma (RCC). The research's goal was to figure out circ-CSPP1's role and molecular mechanism in RCC. The results clarified that circ-CSPP1 expression was enhanced in RCC.

Analysis of Risk Factors for Recurrence after Transurethral Resection of Bladder Tumor in Patients with Non-Muscle Invasive Bladder Cancer: 2-Year Follow-Up Outcomes.

Introduction: The aim was to investigate the risk factors for recurrence after transurethral resection of bladder tumor (TURBT) in patients with non-muscle invasive bladder cancer (NMIBC) and to provide a basis for clinical prevention of recurrence of NMIBC.

Methods: From January 2012 to December 2020, 592 patients with NMIBC who underwent TURBT attending the Second Affiliated Hospital of Xi'an Jiaotong University were retrospectively included in this study. Patients were divided into relapse and relapse-free groups according to whether relapse occurred within 2 years.

Rectifying disorder of extracellular matrix to suppress urethral stricture by protein nanofilm-controlled drug delivery from urinary catheter.

Urethral stricture secondary to urethral injury, afflicting both patients and urologists, is initiated by excessive deposition of extracellular matrix in the submucosal and periurethral tissues. Although various anti-fibrotic drugs have been applied to urethral stricture by irrigation or submucosal injection, their clinical feasibility and effectiveness are limited. Here, to target the pathological state of the extracellular matrix, we design a protein-based nanofilm-controlled drug delivery system and assemble it on the catheter.

High ligation of the hernia sac in open nonmesh inguinal herniorrhaphy is an important cause of iatrogenic vas deferens injury.

Vasectomy damage is a common complication of open nonmesh hernia repair. This study was a retrospective analysis of the characteristics and possible causes of vas deferens injuries in patients exhibiting unilateral or bilateral vasal obstruction caused by open nonmesh inguinal herniorrhaphy. The site of the obstructed vas deferens was intraoperatively confirmed.

MMP9 and TYROBP affect the survival of circulating tumor cells in clear cell renal cell carcinoma by adapting to tumor immune microenvironment.

Circulating tumor cells (CTCs) play a key role in tumor metastasis. CTCs have altered gene expression and can survive in the bloodstream. Finding the key genes whose expression are altered in CTCs could help explain the mechanism of tumor metastasis.

N7-methylguanosine regulatory genes well represented by METTL1 define vastly different prognostic, immune and therapy landscapes in adrenocortical carcinoma.

Although N7-methylguanosine (m7G) is one of the most frequent RNA modifications, it has received little attention.

Herein, a novel m7G risk signature (METTL1, NCBP1, NUDT1 and NUDT5) was constructed using the Lasso regression analysis.

The influence of male and female overweight/obesity on IVF outcomes: a cohort study based on registration in Western China.

Background: Overweight/obesity can affect fertility, increase the risk of pregnancy complications, and affect the outcome of assisted reproductive technology (ART). However, due to confounding factors, the accuracy and uniformity of published findings on IVF outcomes have been disputed. This study aimed to assess the effects of both male and female body mass index (BMI), individually and in combination, on IVF outcomes.

miR-20b-5p is a novel biomarker for detecting prostate cancer.

Prostate cancer (PCa) is the second most frequently diagnosed solid tumor and the fifth leading cause of cancer mortality among men worldwide. The prostate specific antigen (PSA) test for PCa remains controversial. Therefore, the development of more effective non-invasive biomarkers for PCa is necessary.

Resveratrol inhibits TRAF6/PTCH/SMO signal and regulates prostate cancer progression.
