Abstract
BACKGROUND
Whether one positive core prostate cancer (PCa) is a low-risk disease remains to be determined. We investigated the pathological results of radical prostatectomy specimens diagnosed on single core positive prostate biopsy.
METHODS
Between January 2013 and December 2019, A total of 3441 consecutive patients treated with radical prostatectomy in our institution were examined. Among them, 293 patients were diagnosed with single positive core PCa on biopsy, and the clinical parameters and pathological findings of their radical prostatectomy specimens were analyzed.
RESULTS
Of the 293 patients, 108 (36.9%) had undergraded Gleason Scores (GS) based on the biopsy. Positive surgical margins (PSMs), perineural invasion (PNI), extracapsular extension (ECE, pT3a) and seminal vesicle invasion (SVI, pT3b) were found in 16.4%, 15.0%, 3.4% and 2.4% of patients, respectively. In the multivariate analysis, we found that preoperative PSA level predict a significant increased risk of upgraded GS and PSMs, and biopsy GS was is a strong predictor of PNI, upgraded GS, tumor stage pT3 at radical prostatectomy.
CONCLUSIONS
Single positive core PCa have clinically significance in the radical prostatectomy specimens, with considerable rates of undergrading for the GS, PNI, PSMs, ECE and SVI. For patients with single positive core PCa, other prognostic factors must be considered in the treatment plan.
