There is no clear clinical standard for the survival period of multiple metastases of advanced bowel cancer. The survival period of advanced bowel cancer is related to the site of metastasis, whether active treatment is carried out, and the effect of surgery and other comprehensive treatments. 1. Site of metastasis: if only intestinal metastasis occurs, a better prognosis can be achieved after surgical treatment at an early stage, but if extraintestinal metastasis occurs, such as distant metastasis of liver, lungs and other organs, the basic prognosis of the patient is worse, and the survival period is very short, usually around half a year, and in serious cases, the patient will die of systemic organ failure. 2. Whether to carry out active treatment: If the discovery time is early, the curative effect of radical surgical treatment is better, the survival period can be prolonged through effective surgical treatment, and after the surgery, with radiotherapy and chemotherapy and other comprehensive treatments, the local symptoms can be effectively controlled to slow down the progression of the disease. 3. Effectiveness of surgery and other comprehensive treatments: Surgery can remove the lesions very cleanly, with few residual lesions, high sensitivity to post-surgery radiotherapy and other treatments, and good efficacy and prognosis. Patients with advanced metastasis of intestinal cancer need to actively cooperate with doctors for treatment, not to give up on themselves, and need to carry out standardized treatment under doctors’ guidance to prolong the survival period as much as possible.
