OBJECTIVE: Chemoradiotherapy is the mainstay of treatment for the majority of patients with anal cancer, with abdominoperineal resection reserved for salvage. The purpose of this study was to evaluate our results after radiotherapy with or without chemotherapy, and/or surgery in terms of overall survival and colostomy free survival in patients with anal cancer. METHOD: A review of patients diagnosed with anal cancer between 1991 and 2004 was performed. The principle end-points of the study were overall and colostomy-free survival. RESULTS: One hundred and twenty patients were identified. The T stage distribution was T1 32, T2 44, T3 19, T4 17 and TX 8. Eighteen patients had clinically involved regional nodes. Eighty patients received radiotherapy as a component of their treatment. Twenty-four of the 80 patients had a colostomy. The most common late toxicity was faecal incontinence. The overall survival and colostomy-free survival rates for all 120 patients were 58% and 79% at 5 years, respectively. For the 80 patients who received radiotherapy, the corresponding figures were 66% and 82% at 5 years, respectively. CONCLUSION: Chemoradiation is effective organ preserving treatment for anal cancer. Grade 1 and 2 faecal incontinence is a relatively common late toxicity experienced by patients.
