1.Chinese medicine treatment: Chinese medicine treatment for gastric cancer has good effects on improving symptoms, enhancing immune function, stabilizing the balance of internal environment, protecting normal functions of organs, prolonging survival and promoting recovery, which is difficult to be replaced by any western medicine. The principle of Chinese medicine treatment for gastric cancer is to support the positive and dispel the evil. “Support the positive” means to regulate the balance and stability of human body functions and enhance its own anti-cancer ability, while dispel the evil means to eliminate cancer foci, kill cancer cells and control their proliferation. 2.Immunotherapy It is inappropriate to use immunotherapy alone for gastric cancer patients. Immunotherapy, complemented with chemotherapy, can improve patients’ ability to resist cancer, reduce metastasis and recurrence, improve survival rate and prolong life. BCG (BCG vaccine) is most commonly used, usually 5mg of BCG (the number of raw bacteria is about 2-4×108) is applied on the skin of wrist, and then a needle tip is used as a bet. BCG can enhance the non-specific immune response, and OK-32 has the same effect. 3.Intraoperative radiation therapy Patients with pathologically confirmed stage II or III gastric cancer and basically normal cardiopulmonary function can be supplemented with intraoperative irradiation therapy with a one-time irradiation of 20-30 Gy. Although the addition of intraoperative radiation therapy for gastric cancer can improve the survival rate of patients, the general trend is difficult to promote. 4.Gastric cancer monoclonal antibody only binds to gastric cancer cells, but does not react with normal tissues or other tumor cells. If combined with anti-cancer drugs and certain cytotoxins, monoclonal antibodies can play a “biological missile” effect, its role in killing local cancer cells can be enhanced dozens to hundreds of times, especially the post-operative spread of cancer cells kill more, so you can reduce the amount of anti-cancer drugs, reduce the side effects of drugs, thereby improving the therapeutic effect.
