Recurrence of early rectal adenocarcinoma after surgery needs to be treated by surgery, radiotherapy and chemotherapy. Recurrence of early rectal adenocarcinoma after surgery is relatively rare, but once found, it is necessary to improve colonoscopy, CT, tumor markers and other examinations in time to clarify the specific recurrence lesion site, and then surgery, radiotherapy, chemotherapy and other treatments can be taken according to the patient’s condition. If the patient is in good physical condition and the recurrence is in a single site, the metastatic lesion is usually removed through surgery, and radiotherapy and chemotherapy can be taken according to the situation; if the patient is not suitable for surgery or the recurrence of metastasis in multiple sites, radiotherapy, chemotherapy or targeted therapy is needed for comprehensive treatment.
