S131 Secondary Amyloidosis in Inflammatory Bowel Disease Patients: Findings From Three Tertiary Medical Centers

prostate; both these patients subsequently received brachytherapy. After RP, 7 (23%, 7/30) patients had a positive margin. Stereotactic body radiation therapy was performed in only one case of recurrent pelvic lymph nodes (Gleason score 7, grade group 3, pT3bN0M0 with positive margins). The median long-term follow-up after RP was 29 months, and only 1 (3.3%, 1/30) patient developed pouch failure requiring permanent ileostomy due to intractable fecal incontinence 7 years after RP. At 5-years, the overall and disease-free patient survival was 88.5% and 89.7%, and the at 10-years, the overall pouch survival was 85.7%. Only 1 case of death due to prostate cancer recurrence, recurrence 13 years and death 17 years after PR. Conclusion(s): Radical prostatectomy after IPAA is technically challenging and resulted in a positive margin in 23% which is close to the overall median positive margin rate of 20% reported in the literature. Overall long-term patient survival, and pouch survival, was excellent.
