The survival rate of each stage of colon cancer is different. The survival rate of stage I colon cancer is better, for example, the 5-year survival rate is over 90%, the survival rate of stage II colon cancer is about 60%-70%, the survival rate of stage III colon cancer is about 50%, and the 5-year survival rate of stage IV colon cancer, that is, advanced colon cancer, is low, about 10%-20%. The survival rate of stage I colon cancer is relatively high because the tumor invasion depth is relatively shallow and there is no lymph node metastasis, so the patients can basically achieve clinical cure. There are many chemotherapy regimens, commonly used is capecitabine combined with oxaliplatin, and patients need to follow up regularly in hospital within 5 years. However, if the tumor progresses during the treatment process, such as advanced colon cancer, the overall survival of patients will be shortened, that is, low, and for colon cancer that is itself advanced, the survival rate of patients will be even lower, because the tumor has developed distant metastasis, so it will soon lead to the spread of the whole body.
