Table 3. Lateral Local Recurrence (LLR) Rates and Overall Recurrence (OAR) Rates for Different Cutoff Values in Short-Axis (SA) Node Size on Restaging Magnetic Resonance Imaging (MRI) Among Patients With an SA Node Size of 7 mm or Greater on Primary MRI Who Underwent Chemoradiotherapy or Radiotherapy With Total Mesorectal Excision, Separated by Compartment.
