Can colorectal cancer be cured in the mid-term?

According to incomplete statistics, in 2005, colorectal cancer has become the second most common malignant tumor. Cancer is terrible for any family. Now, with the improvement of living standards, the incidence of colorectal cancer is also increasing. At this time, many people are concerned about whether colorectal cancer can be cured? Is having colorectal cancer equivalent to being sentenced to death?

In fact, not all cancers are incurable. Regarding the treatment of colorectal cancer, many scholars at home and abroad have studied the relationship between the histological type of colorectal cancer, lymph node metastasis and other factors and prognosis and found that the 5-year survival rate is still not low, which also shows that colorectal cancer is not an incurable disease, that is to say, colorectal cancer can be cured.

However, because the prognosis of colorectal cancer is related to many factors and involves the biological characteristics of the tumor, whether it can be completely cured is also related to factors such as early diagnosis and staging, and treatment methods.

Dukes staging: Dukes theory reveals that colorectal cancer mainly grows in a circular infiltrative manner around the intestinal wall and metastasizes to the lymph nodes, reflecting the biological behavior of the cancer. It is a standard for accurately reflecting the extent of the disease, selecting treatment options, and evaluating prognosis.

Differentiation level of cancer cells: those with low differentiation have a poor prognosis.

Age of onset: Young patients have a worse prognosis than older patients.

According to surveys, the 5-year survival rate of patients who have intestinal obstruction when they seek medical treatment is generally only half of that of those without intestinal obstruction. Patients with complications such as intestinal bleeding, perforation, and purulent peritonitis have a poor prognosis. This shows that colorectal cancer is not the legendary "incurable disease". If it can be detected in the early stage and treated correctly, it is still possible to achieve long-term survival.
