Preoperative magnetic resonanceimaging (MRI) may be useful in predictingprostate cancer-specific mortality(PCSM) after radical prostatectomy(RP), according to Korean researchers.
Sungmin Woo, MD, and colleaguesat the Seoul National University studied318 patients who underwent MRI followedby RP. After a median follow-upof 104 months, 11 patients (3.5%) diedfrom prostate cancer.
Of the 318 patients, 104(32.7%) had clinically significant canceron MRI. These patients had 5- and10-year PCSM rates of 8% and 14.2%,respectively, whereas patients withoutclinical significant cancer had rates of0% and 0.5%, respectively, the investigatorsreported online in Acta Radiologica.In multivariate analysis, clinically significant cancer on MRI was associated withan 11-fold increased risk of PCSM.
