Accelerated radiotherapy in the treatment of anal squamous cell carcinoma - a single institution retrospective evaluation.

Background: The goal of treatment for anal squamous cell carcinoma (ASCC) is to preserve a functional anal sphincter and maintain the best quality of life. Surgical excision is reserved only for very early stages, and concomitant chemoradiotherapy (CHRT) is usually used in the treatment of ASCC. The aim of the study is a retrospective analysis of a group of patients with ASCC treated with CHRT using accelerated radiotherapy at the Institute of Radiation Oncology of Bulovka University Hospital in Prague (IRO BUH).
