Survival of patients with multiple metastases of rectal cancer is generally roughly assessed by 5-year survival rate, which is less than 30%. At present, there is no clear data indicating how long rectal cancer with multiple metastases can live, and it needs to be judged according to the degree of disease, whether timely treatment and other factors, and most of the survival time is less than 5 years. Usually, for early stage rectal cancer patients without lymph node metastasis, the 5-year survival rate can be as high as 90% after active surgical treatment, but there is a risk of recurrence. As for patients with locally progressive rectal cancer, the 5-year survival rate is 50-78% after standardized treatment as prescribed by doctors. However, patients with multiple metastases have relatively shorter survival time, and the 5-year survival rate is less than 30%. Patients can prolong their survival time through chemotherapy, targeted therapy, immunotherapy and other ways. It is recommended that rectal cancer patients with multiple metastases should actively cooperate with doctors to take appropriate treatment measures to prolong their survival time. 5-year survival rate, median survival period and other statistical data generally represent the situation of a certain group of patients, and do not represent the specific survival period of individuals, the individual survival period of lung cancer patients needs to be determined by combining many factors, and it is recommended to consult with the physician.
