Patients and Methods: Between 1990 and 2006, 83 patients affected by anal canal carcinoma were treated at the Radiotherapy Department of “La Sapienza” University of Rome. In all patients, a daily dose of 1.8 Gy, five times per week, was given for a total dose of 45 Gy for the whole pelvis (CTV1) and of 55-60 Gy for the tumor bed (CTV2). In 63 patients, chemotherapy consisted of two cycles of 5-fluorouracil (5-FU) and mitomycinC (MMC) or cisplatin delivery during the first and last week of radiotherapy. Results: The median follow-up time for all patients was 56.2 months. Treatment response was considered complete in 53 patients (63.8%) and partial in 30 patients (36.1%). Local tumor relapse was observed in 13 patients (15.6%). The probability of overall survival for all patients at 5 years was 75%: 39% in patients who underwent radiotherapy alone and 85% in patients who underwent radiochemotherapy (p=0.0013). Concerning acute toxicity, 9 patients developed grade 1 skin toxicity (10.8%), 35 grade 2 (42.1%), 26 grade 3 (31.3%) and 3 grade 4 (3.6%); eleven patients had grade 2 diarrhea (14.5%) and 2 grade 3 diarrhea (2.4%). Conclusion: This analysis suggests that the treatment scheme employed was effective for anal sphincter preservation and local control.
