Combined therapy for cancer of the anal canal

Nineteen patients with squamous-cell cancer of the anal canal have been treated with combined chemotherapy and radiation therapy, followed by appropriate surgery. The authors are convinced that the combined therapy is effective enough to avoid abdominoperineal resection if disappearance of the lesion is proven by adequate examination and biopsy. Although they believe cancers 5 cm or less in maximum diameter are generally adequately managed in this manner, experience is still too limited to justify a recommendation to change currently accepted management.
