Anal cancer is a rare disease, but the incidence is rising. About 200 patients will get this type of cancer yearly in Sweden. Curative treatment includes chemotherapy and radiotherapy. The prognosis is good, but some patients will have recurrent or persistent disease after concluded chemo-radiotherapy and will then be offered salvage surgery. Some patients develop distant metastases that can be treated with good results. The aim of this study is to identify and describe functional outcome in patients diagnosed with anal cancer. We will study patients from diagnosis, try to identify early toxicity to treatment and then identify long-term morbidity.
