Recurrences after transanal excision or transanal endoscopic microsurgery of T1 rectal cancer

Local excision for T1 rectal cancer is increasingly applied, in a strive to avoid the morbidity associated with radical surgery, despite limited evidence. One of the issues is the high rate of local recurrence following local excision (LE). In this article we focus on this item and review the literature articles concerning local excision and transanal endoscopic microsurgery (TEM), recurrence, and salvage surgery. Local recurrence rates after LE or TEM are unacceptably high. As outcome of this subgroup is limited, future studies should focus on proper tumor selection and adjuvant treatment strategies following salvage surgery.
