How effective is biological immunotherapy in treating colorectal cancer

Colorectal cancer is a disease that endangers people's lives and health. With the continuous advancement of medical technology, people can now treat colorectal cancer in many ways. The treatment methods vary depending on the early and late stages of colorectal cancer. So how effective is biological immunotherapy for colorectal cancer?

What is biological immunotherapy?

Biological immunotherapy is the latest tumor treatment technology after surgery, radiotherapy and chemotherapy. It is aimed at preventing the recurrence of malignant tumors. Its principle is to separate the monocytes in the patient's peripheral blood in vitro, and through the action of specific antigens and laboratory culture, enable them to have the ability to specifically kill tumors. At the same time, after expanding this type of cell to a certain number in vitro, it is then returned to the body to kill tumor cells that are invisible to the naked eye, thereby preventing the recurrence and metastasis of the tumor.

What are the advantages of biological immunotherapy?

To a certain extent, it solves the serious problem of poor immunity and low quality of life of patients after radiotherapy and chemotherapy. And because the mechanism of autologous cell immunotherapy can improve the patient's immunity, it can greatly delay the patient's survival time to a certain extent.
