The survival rate of stage III colon cancer is not very high, but through scientific and correct treatment, the five-year survival rate of patients can reach about 70%. Colon cancer is a common digestive tract tumor in China, and in the past 20 years, the incidence rate has risen significantly, with the trend that there are more colon cancers than rectal cancers. For the survival of cancer patients, it can’t be simply said that it is good or bad. It is necessary to consider the patient’s stage, grading, physical condition, treatment means and so on. At present, five-year survival rate is commonly used in clinical practice to assess the survival of cancer patients. According to TMN staging, the five-year survival rate of stage I patients is more than 90%, that of stage II-III patients is about 70%, that of stage IV patients with radical resection is about 30%, and that of palliative treatment is 8%. There are no obvious symptoms in the early stage of colon cancer, but after the development of the disease, there may be changes in bowel habit, abdominal pain, symptoms of intestinal obstruction, anemia, weight loss, etc. Currently, the main treatment for colon cancer is to cure the disease. At present, the treatment for colon cancer is mainly surgery-based comprehensive treatment. It is recommended that patients should seek medical treatment in time, and under the guidance of doctors to carry out standardized and individualized treatment to prolong the survival.
