Emvi Rectal Cancer: Comprehensive Guide To Early-Stage Tumors Near The Anal Verge
EMVI rectal cancer refers to early-stage, very low-lying rectal tumors that invade the external sphincter muscle and/or the anal canal. These tumors are located within 2-3 cm from the anal verge and are typically diagnosed by digital rectal examination or endoanal ultrasound. EMVI rectal cancer is classified ascT1-3N0M0 according to the American Joint Committee on Cancer staging system and is treated with neoadjuvant chemoradiotherapy followed by local excision.
