Patient Question: Disease:Tumor location is less than 3CM from anus, can I save my anus? Description of disease:Rectal tumor, section results are not yet available. But surgery should be mandatory. Wish to provide help:1. The tumor is located less than 3CM from the anus, and I want to know whether the anus can be preserved if the surgery is performed. 2. Is it possible to use minimally invasive surgical methods? Medication:Drug name:IV Instructions for use:Unknown Response from Lin Hongwei: The tumor has involved the anus and radical surgery to preserve the anus is not possible. According to the patient’s pathological classification, age, requirements for quality of life, and other comprehensive factors, such a low position, if the anus must be preserved, multidisciplinary integrated treatment is needed, combined with radiotherapy. There is hope that the rectal tumor can be completely cured under the management of an experienced radiotherapist. Surgery is not considered for the time being.
