How long does rectum cancer radiate

Treatment 1: the indication of postoperative radiotherapy for rectal cancer should be determined according to the surgical findings and postoperative pathological stage. If the local lesion is late in the operation, the tumor has invaded the deep muscle layer, or penetrated the intestinal wall, or the lesion site has cancerous adhesion with pelvic tissues or organs, and there are metastatic lymph nodes in the intestinal wall or pelvic cavity. If the Dukes stage is B2, C1 and C2, postoperative radiotherapy should be performed.

Treatment 2: the advantages of postoperative radiotherapy: ① clear postoperative staging, 10% - 15% of t-znom and intraoperative exploration of patients with liver metastases can avoid unnecessary irradiation; ② silver clips can be placed in the operation to accurately mark the scope of the hospital bed; ③ the operation time will not be prolonged, which will affect the wound healing.

Treatment 3: disadvantages of postoperative radiotherapy: (1) the small intestine falls into the pelvic cavity after operation, and the amount of small intestine is increased during radiotherapy. (2) the operation may affect the blood flow in the local area, cause hypoxia, and affect the curative effect. (3) because the radiotherapy after Miles operation includes scar removal, the radiation field is expanded.
