Long-term results in patients with T2-3 N0 distal rectal cancer undergoing radiotherapy before transanal endoscopic microsurgery.

The article examines the results of local excision in patients with small T2 and T3 distal rectal tumors after neoadjuvant therapy. All patients underwent preoperative radiotherapy followed by local excision through transanal endoscopic microsurgery. The study concludes that treatment of small uT2 and uT3 uN0 rectal cancers with preoperative high-dose radiotherapy followed by transanal endoscopic microsurgery is an alternative to traditional radical resection.
