Patients With Low Rectal Cancer Treated by Abdominoperineal Excision Have Worse Tumors and Higher Involved Margin Rates Compared With Patients Treated by Anterior Resection

Abstract

Patients undergoing abdominoperineal excision have higher involved margin rates; however, they had lower and more locally extensive tumors despite a greater proportion undergoing neoadjuvant therapy. Patients with low rectal cancer pose difficulties with regard to optimal management. Targeted strategies are needed to improve outcome in this complex and common cancer.
