Assessment of Textbook Oncologic Outcomes Following Proctectomy for Rectal Cancer.

Background: Outcomes of rectal adenocarcinoma vary considerably. Composite "textbook oncologic outcome" (TOO) is a single metric that estimates optimal clinical performance for cancer surgery.

Methods: Patients with stage II/III rectal adenocarcinoma who underwent single-agent neoadjuvant chemoradiation and proctectomy within 5-12 weeks were identified in the National Cancer Database (NCDB).
