Advanced stages of colon cancer include Stage III and Stage IV, with varying survival rates. The 5-year survival rate for stage III colon cancer is 20-30%, while the 5-year survival rate for stage IV colon cancer is often less than 10%. Colon cancer survival rates are related to the patient’s treatment and drug sensitivity. General transformation therapy or gene immunotherapy, etc. can also significantly improve the survival rate of advanced tumors. In patients with advanced tumors, there are not many life-prolonging treatments, and improving the quality of life needs to be put in the first place. For example, intestinal obstruction catheterization can reduce the symptoms of abdominal distension and abdominal pain, and other methods include nutritional immunotherapy and psychotherapy.
