The existence of positive surgical margins (PSMs) after radical prostatectomy (RP) will greatly increase the risk of tumor recurrence in patients.
The presence of positive surgical margins (PSMs) after radical prostatectomy (RP) will greatly increase the risk of tumor recurrence in patients.
Because MRI (mpMRI) imaging can provide information such as pelvic anatomy, prostate volume, tumor location, etc.
This study retrospectively evaluated consecutive prostate cancer patients who received RP treatment from a tertiary referral hospital.
