What's your follow up protocol for a near complete response (nCR) in rectal patients considering non-operative management (NOM)?  

OPRA trial recommends continued NOM if no signs of progression in nCR patients vs. NCCN recommends repeat studies at 8 weeks and if not converted to clinical CR then proceed to TME.

Which recommendation do you use and during your follow up period, how do you address nodes when assessing response?
