abdominoperineal resection

The surgical excision of the lower rectum and anus, resulting in the loss of the anal sphincter and a need for colostomy.
Results
Local control, 60–80%; 60–90% 5-year survival; for larger lesions, RT and 5-FU and mitomycin are used.
APR is less preferred than RT for small lesions + external beam treatment or with radioactive implants—e.g., 198Iridium seeds.
