A retrospective study was conducted for evaluation of the therapeutic efficacy of the various modalities for treatment of carcinoma of the anal canal. Thirty-seven patients were reviewed. Patients commonly presented in their sixth decade of life and a four-fold predominance of women was noted. Tumor histopathology was of little relevance in determining prognosis. Surgery alone was performed on 15 patients, consisting of either abdominoperineal resection or wide excision. Multidisciplinary therapy as described by Nigro et al.,10-12 which included preoperative chemotherapy and radiation followed by surgery within a period of 4-6 weeks, was used to treat 13 patients. Radiation alone or in combination with surgery was used to treat six patients. One patient refused further treatment following radiation and chemotherapy, and the remaining two patients refused treatment from the onset. There was no difference in survival in Stages 0 and I patients when treated by surgery alone or with the Nigro protocol. However, Stages II and III patients had a more favorable outcome when treated by the Nigro protocol than by any other regimen. Thirteen of 21 patients treated by surgery and/or radiation therapy developed recurrence, resulting in seven deaths. Three out of 13 patients treated by the Nigro protocol developed recurrence, all of whom are alive and well following salvage treatment. Despite its infrequent use, a favorable trend is noted as a result of utilizing the multimodality protocol, particularly in patients with invasive disease.
