How would you treat completed resected rectosigmoid recurrence of endometrial adenocarcinoma?  

This patient previously received hysterectomy with adjuvant vaginal cuff brachytherapy without pelvic RT. Colonoscopy demonstrated invasive disease, biopsy-proven to be recurrent endometrioid adenocarcinoma.

Salvage surgery done with negative margins and end-to-end anastomosis, but +LVSI and mesorectal tumor deposits on final path. No evidence of vaginal cuff or regional node recurrence, on staging workup, and no visible extrapelvic disease.
