[Clinical Outcome of the Patients with Anal Squamous Cell Carcinoma]

We studied 14 patients with anal squamous cell carcinoma(ASCC)who were treated in our hospital between 1994 and 2016. As initial therapies, surgeries were performed in 5 patients. Of these, disease recurrence appeared in 4 patients, and 3 patients died within 1 year after operation. Other 9 patients were treated with chemoradiotherapy. As a result, 9 of 6 patients were considered as complete response(CR), and 4 patients are still alive without recurrence. Although other 2 patients were recurred, recurrent lesions were removed and then, they are still alive. Of 3 patients who were considered as partial response (PR), 1 patient who was treated with local excision is still alive without recurrence, however, 2 patients were died for distant metastases. Chemoradiotherapy is considered to be effective and expected to cure without surgery, however, a careful surveillance should be needed for distant metastases.
