PUC severity and location were evaluated on the midsagittal plane during transrectal ultrasonography.

From January 2018 to October 2019, fusion mpMRI and TRUS-guided biopsies were performed in 162 consecutive patients. The study included 188 suspicious lesions on mpMRI in 156 patients, all of whom underwent mpMRI-TRUS fusion imaging-guided TB and 12-core transperineal systematic biopsy (SB). Univariate analyses were performed to investigate the relationship between TRUS features and PCa. Then, logistic regression analysis with generalized estimating equations was performed to determine the independent predictors of PCa and obtain the fitted probability of PCa. The detection rates of PCa based on TB alone, SB alone, and combined SB and TB were 55.9% (105 of 188), 52.6% (82 of 156), and 62.8% (98 of 156), respectively.

Surgical International Society of Urological Pathology PCa grades (ISUP Grade Group) ≥4 was significantly associated with poorer PSS (hazard ratio [HR] = 8.52, 95% confidence interval [CI]: 1.42-51.25, P = 0.02). Pathological T3 stage was not significantly associated with PSS or OS in our cohort. Lymph node invasion and extracapsular extension might be associated with worse PSS (HR = 20.30, 95% CI: 1.22-336.38, P = 0.04; and HR = 7.29, 95% CI: 1.22-43.64, P = 0.03, respectively). Different surgical approaches (open, laparoscopic, or robotic-assisted) had similar outcomes in terms of PSS and OS. In conclusion, we report the longest timespan follow-up of Chinese PCa patients after RP with different approaches.</p>","PeriodicalId":8483,"journal":{"name":"Asian Journal of Andrology","volume":"25 3","pages":"345-349"},"PeriodicalIF":2.9,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/32/da/AJA-25-345.PMC10226499.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9541153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
