Distal resection margin (DRM) and circumferential resection margin (CRM) are two important considerations in rectal cancer management. Although guidelines recommend a 2 cm DRM, studies have shown that a shorter DRM is adequate, especially in patients receiving neoadjuvant chemoradiation. Standardization of total mesorectal excision has greatly improved quality of CRM. Although more patients are undergoing sphincter-saving procedures, abdominoperineal resection is indicated for very distal tumors, and pelvic exenteration is often necessary for tumors involving pelvic organs.
