T1, select T2, no evidence of nodal or metastatic disease local excision +/- adjuvant treatment Radical resection
If T3/T4 or evidence of nodal disease neoadjuvant treatment (because high risk of locoregional recurrence)

5 ½ weeks of radiation and chemotherapy 6-8 weeks recovery Low anterior resection vs APR with diverting
ileostomy (3 months after diagnosis) 6 month of adjuvant chemotherapy Ileostomy reversal (9 months after starting
treatment)

Better local control Better vascularized and oxygenated tissue is more
sensitive to radiation Decreased toxicity Downstaging tumor More likely to preserve sphincters
Decrease radiation injury to small intestine Remove irradiated tissue Sterilizing tumor, decrease risk of tumor spillage
