Traditional Chinese medicine is one of the five indispensable means (surgery, chemotherapy, radiotherapy, biological therapy and traditional Chinese medicine) in the treatment of tumors, and has an irreplaceable and important role: 1. Traditional Chinese medicine has a direct killing effect on cancer cells Some people think that traditional Chinese medicine is in a subordinate and auxiliary position in the treatment of tumors, and can only improve the quality of life of patients and cannot shrink tumors. In fact, the ancients have long recognized the existence of tumors. More than two thousand years ago, the book “Huangdi Neijing” already had the description of “accumulation”, “disease” and “tumor”, which are similar to malignant tumors. The Chinese herbal medicine has been used to treat various tumors by softening and dispersing hard nodes, activating blood circulation and removing blood stasis, and clearing heat and toxins. Modern flow cytometry technology reveals that many herbal medicines do have direct tumor-killing effects, for example, some herbal medicines have direct effects on the cell cycle of human lung adenocarcinoma, among which single herbal medicines that can reduce the proportion of S-phase cells include gynostemma, northern ginseng, ginseng, prunus ginseng, etc., and northern ginseng, chasteberry, and stone see-through, etc. that can stop cell mitosis. Another example is the colchicine mushroom and its derivative colchicine amide, which have inhibitory effects on mouse sarcoma S180, S37 and hepatocellular carcinoma ascites type, the latter inhibiting 61%, 68.1% and 77.7% of the above three tumor strains. Some people have used compound colchicine and colchicine injection as tumor chemotherapy to treat breast cancer, cervical cancer, esophageal cancer, lung cancer and gastric cancer, etc., and also achieved remarkable results. Using modern technology, he has successfully developed Eleutherococcus lactis injection from Curcuma longa, Conrad injection from Coix seeds, and Edy injection from Zanthoxylum, all of which have achieved impressive clinical efficacy. Therefore, Prof. Zhou believes that we should change the prejudice that traditional Chinese medicine can only supplement and cannot shrink tumors. When the patient’s physical condition allows, it is more important to emphasize attacking evil and eliminating cancer, attacking when it can, strengthening the use of phlegm dispersing, blood activating and blood stasis removing and worm medicine, treating tumor fundamentally to promote tumor shrinkage. 2. Chinese medicine can improve the body’s immune function against tumor cells Modern immunology research has found that the immune function of all animals is controlled by an extremely complex and precise immune regulation network, any one of which Any one of these links will cause the normal immune regulation to be out of balance and affect the immune defense. Immunity affects both tumor growth and immune changes in the tumor-bearing host. Therefore, if we can find ways to regulate the immune function of immunocompromised tumor patients, it will certainly facilitate the control of tumors. This is the current emerging tumor immunotherapy, i.e. the biological treatment for tumors. Studies have shown that Chinese medicine can increase the natural killer cells and TNF content in mice, causing lymphocytes and monocytes to infiltrate around tumor tissues and causing discrete degeneration and necrosis of cancer cells. Chinese herbal medicines such as nourishing qi and blood, nourishing yin and helping yang, tonifying kidney and liver have been found to have good immunomodulatory effects through clinical observation and animal experiments. Turtle shell, Astragalus, princely ginseng, Ganoderma lucidum and ginseng, Zhengqi Fuzheng capsule, Qizhen capsule, Ginseng injection, Ginseng tablets, etc. have significant immune promoting effects. Compared with western medicine immune boosters, these drugs are cheap, easy to take, and have no side effects, which is a “biological treatment” with Chinese characteristics. 3.Reducing the toxic side effects of radiotherapy or chemotherapy While killing cancer cells, radiotherapy or chemotherapy is bound to kill a large number of normal cells in the body and produce various toxic side effects, such as bone marrow If the radiation therapy or chemotherapy kills cancer cells and also kills a large number of normal cells in human body, it will produce various toxic side effects, such as suppression of hematopoietic function, immunosuppression, gastrointestinal reaction, hair loss, radioactive or chemical inflammation, etc. If Chinese medicines are taken at the same time, it can reduce these side effects, so that radiotherapy can be completed successfully and the tolerated dose of radiotherapy can be increased. For example, Chinese herbal medicines for nourishing the liver and kidney have a certain effect on protecting liver and kidney functions and promoting hair regeneration after hair loss. Chinese herbal medicines for clearing heat and detoxifying, nourishing Yin and moistening dryness are clinically effective in preventing and treating radioactive stomatitis, esophagitis and cystitis. The study found that some Chinese herbal medicines combined with chemotherapy drugs have enhanced the efficacy of radiotherapy or chemotherapy drugs, which is medically known as potentiation and sensitization. For example, Poria cocos extract (polysaccharide) alone, no significant inhibition of animal tumors, but if Poria cocos extract with cyclophosphamide, it can be seen that the rate of inhibition of animal tumors than the rate of inhibition of cyclophosphamide alone significantly increased, with a significant synergistic effect. Therefore, in radiotherapy at the same time, with the use of Chinese medicine, to promote the recovery and healing of the disease, to improve the therapeutic effect is very beneficial. 5, prevention of recurrence of anti-metastatic effect. Although cancer patients have undergone surgery, lymph node metastasis or metastases in other locations in the body, those tiny lesions which are still invisible and inaccessible are the root cause of recurrence in the future. At most, the adjuvant chemotherapy after surgery can only eliminate the tumor cells to 106 level, and the following depends on the patient’s own immunity. In this case, traditional Chinese medicine can mobilize the anti-cancer power of T-lymphocytes and NK cells to destroy the residual cancer cells and prevent metastasis and recurrence. 6.Improve the quality of survival. Patients with middle and late stage tumors have various symptoms, such as wasting, poor appetite, low fever, pain, weakness, etc., which bring great pain to patients and affect their quality of life, while the application of traditional Chinese medicine has good effect, can significantly improve the quality of life and prolong the survival period.
