Abstract:
In the past, abdominoperineal resection was routinely performed for anal canal cancer, yet it is now known that squamous cell carcinoma of the anal canal has a favorable prognosis and it rarely requires radical surgery. Furthermore, T1 anal cancer, which represents about 10% of all anal canal cancers, has an excellent prognosis. Endoscopic mucosal resection (EMR), which has been used for removal of early-stage adenocarcinoma of the rectum, has not been reported as a treatment option for squamous cell carcinoma of the anal canal because making the endoscopic diagnosis of early-stage anal canal cancer is very difficult. We have experienced a case of early-stage squamous cell carcinoma of the anal canal that was identified without symptoms during routine screening colonoscopy and it was removed by EMR. As far as we know, it is the first case of early-stage anal canal cancer that was diagnosed and treated by endoscopic mucosal resection.
