Oncologic Outcomes for Local Excision of Rectal Neoplasia

Local excision is a safe alternative to radical resection for benign lesions and early rectal cancer. Technological advances in local excision, such as transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS), have led to improved pathologic specimens with higher negative margin rates and less specimen fragmentation leading to improved oncologic outcomes. In select patients with T1 rectal cancers without adverse features, local excision with curative intent is associated with similar oncologic outcomes compared to TME surgery. Patients with more advanced tumors that refuse TME surgery or are medically unfit can be considered for neoadjuvant chemoradiation followed by local excision with low incidence of local recurrence and comparable disease-free survival as TME.
