The 5-year survival rate of colon cancer at age 70 is over 90% for stage I, 70% for stage II to III, and up to 30% for stage IV.
The stage of colon cancer, type of pathology and treatment are all closely related to the specific life expectancy of colon cancer and cannot be generalized. Five-year survival rate is a commonly used metric to assess survival in colon cancer.
Based on TMN staging, the five-year survival rates for stage I through IV colon cancer are >90%, 70%, 70%, 30% (radical surgery) or 8% (palliative care), respectively.
The histologic types of colon cancer vary, and thus the prognosis of colon cancer is relatively different. Mucinous adenocarcinomas, impression cell carcinomas and undifferentiated carcinomas of colon cancer are more malignant and have a relatively poorer prognosis. Meanwhile, the prognosis is also related to the treatment methods and the patient’s own condition.
Since colon cancer has no specific symptoms in early stage, it is easy to be missed in clinic. Therefore, early detection, early diagnosis and then early treatment are required, and the use of scientific and reasonable treatment methods can delay the progress of colon cancer and improve the quality of life as much as possible.
