Immunochemotherapy mainly achieves anti-tumor effect by repairing and enhancing the function of body’s immune system, while chemotherapy achieves anti-tumor effect by interfering with the synthesis of DNA, RNA, protein or interfering with cell division. Immunochemotherapy: Immunochemotherapy refers to the addition of anti-immunotherapy drugs on the basis of chemotherapy, which makes use of the body’s immune mechanism to enhance the immune function of tumor patients through active or passive methods to achieve the purpose of killing tumor cells to the maximum extent. Immunotherapy for tumor includes specific immunotherapy and non-specific immunotherapy. In the former case, the treatment mainly targets the tumor antigens produced by tumor cells and induces a specific immune response, while in the latter case, it mainly uses some cytokines, bacteria or microorganisms and other extracts to improve the overall immune status of the body and achieve the effect of indirect anti-tumor. Chemotherapy: Chemotherapy is a therapeutic method that uses chemically synthesized drugs to destroy cancer cells and inhibit the growth of tumor cells. It mainly works by interfering with the synthesis of DNA, RNA and protein or interfering with cell mitosis. Chemotherapeutic drugs mainly act on tumor cells, but sometimes damage normal cells to different degrees, resulting in side effects such as nausea, vomiting, hair loss and bone marrow suppression. The drugs can be administered by oral, intravenous and body cavity routes, and the drugs can reach most of the organs and tissues with blood circulation. During the treatment, it is recommended to eat more food containing high protein and vitamins, eat less and more frequent meals, have a regular routine, keep a good mood, and develop good living habits.
