Clinical T2N0 Rectal Cancer Treated with Neoadjuvant Chemoradiotherapy plus Local Excision.

Introduction: Total mesorectal excision is the standard treatment for clinical T2 (cT2) rectal cancer; however, this procedure can result in postoperative dysfunction, decreased quality of life, and stoma creation in some patients. We investigated neoadjuvant chemoradiotherapy (nCRT) plus local excision (LE) as an alternative treatment strategy for patients with cT2N0 rectal cancer.

Method: Fifty-six patients with cT2N0M0 rectal cancer who exhibited the following characteristics (an anal verge of ≤8 cm, tumor size of <30 mm, well- or moderately differentiated adenocarcinoma on biopsy) underwent LE following nCRT.
