There is no definite time for how long the liver metastasis of small bowel cancer can live, and it is related to the severity of the patient’s disease, which can be as heavy as a few months or as light as a few years. 1. Only a few months: for patients with advanced small bowel cancer, if there are multiple liver metastases and the lesions are large in size and extensive in invasion, surgical treatment will not be possible, coupled with the poor physical condition of the patients, the survival rate will be greatly reduced, and it may only be a few months, and the 5-year survival rate will be less than 5%. 2. About 5 years: when liver metastasis of small bowel cancer occurs, if the metastatic lesion is small and limited, if radical surgery for small bowel cancer is carried out along with resection of liver metastasis, and the patient actively cooperates with postoperative chemotherapy, the patient’s median survival period will be about 3 years, and the 5-year survival rate will be 30%-57%. While actively cooperating with doctor’s treatment, patients with liver metastasis of small bowel cancer need to have a good mindset to delay the survival period, and if there is any discomfort, please consult the doctor in time so as to avoid delaying the condition.
