MP51-09 THE UTILITY OF NOVEL QUANTIFICATION USING IMAGING SOFTWARE FOR ANALYZING WHOLE-BODY MAGNETIC RESONANCE IMAGING OF PATIENTS WITH METASTATIC PROSTATE CANCER

roughly 80% of positive TBx cores for patients with ISUP 4-5 at TBx. Conversely, for patients with ISUP 2-3 and ISUP 1, the 2-year BCR probability remained stable regardless of TBx ratio. CONCLUSIONS: Tumor load within the IL was significantly associated with patient outcome only in men with biopsy ISUP grade 45. These results should be taken into account during pre-operative treatment planning and overall patient risk assessment.
