Biological therapy refers to the use of new biotechnology to prepare, cells, biological macromolecules (nucleic acids, proteins and peptides) or small molecules to regulate biological reactions as a means of special “drugs”. It has certain effect on the treatment of malignant tumors, but the specific needs to be combined with the patient’s condition.
Biotherapy is a technology that combines gene therapy, immunotherapy, stem cell therapy and other therapies, such as PD-1/PD-L1 monoclonal antibody immunotherapy, interferon, interleukin-2 and so on, which can be used in a variety of cancer treatment. At present, the more commonly used is cellular immunotherapy, through the immune checkpoint inhibitors, the drug will act on the cancer cells so as to achieve the killing effect, the overall effect is still good.
However, biotherapy has not been widely used in clinical treatment, clinical reference data is lacking, but it is very promising to become a new means of treating cancer disease in the future, which is worth looking forward to.
