The clinical treatment of tumors in the elderly is guided by the “internal deficiency theory”. For a long time, the treatment of tumors in Western medicine is usually based on surgery, radiotherapy and chemotherapy, which are the “three axes”. While the cancer cells are destroyed, the whole body also fails, resulting in the premature end of life. Based on the “internal deficiency theory” of Chinese medicine, Tang Wujun takes the balance of yin and yang within the human body as the starting point, adopts the combination of Chinese medicine and Western medicine, and the combination of treatment methods to help the positive and eliminate the evil, to help the positive and strengthen the root, to eliminate the evil in the body, to rationalize the meridians and blood, and to restore the function of internal organs. In order to achieve the purpose of alleviating the disease, we use a combination of Chinese medicine and Western medicine, and the combination of treatment methods to support the root cause, eliminate the evil energy in the body, rationalize the meridians and blood, and restore the function of the internal organs. The “internal deficiency theory” focuses on strengthening the spleen and tonifying the kidneys. Since graduating from university in 1988, Tang Wujun has been engaged in the treatment and prevention of tumor diseases in the elderly. He is a member of the Beijing Anti-Cancer Association Professional Committee of Integrative Chinese and Western Medicine, a member of the Tumor Expert Committee of the Integrative Chinese and Western Medicine Branch of the Chinese Physicians Association, a disciple of the third batch of national famous old Chinese medicine experience successors, and a famous Chinese medicine oncologist, Yu Rencun. Through his long-term clinical practice, he proposed the “internal deficiency theory” of tumor pathogenesis, and pointed out that the core of this theory is to apply the method of strengthening the spleen and tonifying the kidney to improve the anti-disease ability of cancer patients, improve the functional state of the body, reduce the patient’s pain, improve the quality of survival, and thus increase the long-term survival time and survival rate. In his academic research, he is guided by the “internal deficiency theory” of Chinese medicine and uses a combination of Chinese and Western medicine to treat common malignancies and their complications, such as lung cancer, stomach cancer, colon cancer, liver cancer, pancreatic cancer, esophageal cancer, and breast cancer. He has participated in the clinical studies of “Guben Tumor Suppressing II combined with chemotherapy for advanced non-small cell lung cancer”, “Guben Tumor Suppressing Capsule combined with single agent chemotherapy for advanced non-small cell lung cancer”, and “Liver Drainage The research projects include “Treatment of postoperative lymphedema of the upper limbs of breast cancer by combining physiotherapy with the method of Tongluo”, “Prevention of neurotoxicity of chemotherapy drugs by Chinese herbal infusion”, and “Treatment of radioactive proctitis by Chinese herbal preserved enema”, among which, the research project Among them, the scientific research project “Anti-tumor Research of Solid State Tumor Suppression II” was awarded the Beijing Science and Technology Progress Award. With the advent of global aging society, the number of elderly tumor patients has increased significantly. In his clinical practice, Tang Wujun has noticed that many clinical trials have not included elderly patients due to their reduced physiological function and other comorbidities, resulting in a lack of clinical guidelines for oncology clinicians to make treatment decisions for elderly tumor patients. The age factor is important in the development of tumors, and the older the age, the higher the incidence. Tang Wujun said, “Yu Rencun proposed the ‘internal deficiency theory’ in the etiology of tumors, pointing out that internal deficiency is the root cause of tumor development. The so-called “internal deficiency” refers to the imbalance of qi, blood, yin and yang of the internal organs. The function of the internal organs of the elderly is gradually declining, manifesting as a deficiency of both yin and yang, but the relative balance between the two is maintained, which is called a state of subhealthy equilibrium. This balance is a fragile balance, easily affected by other factors and lead to the destruction of the balance, and the duration of the imbalance is relatively longer than that of the non-elderly population, resulting in a weaker ability to resist disease, prone to disease and difficult to heal after illness. The elderly have a reduced vitality and a deficiency of qi and blood, so they are often suffering from deficiency, or a mixture of deficiency and reality, so it is advisable to treat deficiency with tonics, and to be cautious in attacking evil when deficiency is mixed with reality, and to be light in medication. Chinese medicine plays an important role in cancer treatment by regulating the patient’s yin and yang, and the imbalance of internal organs, adjusting the internal environment of the patient’s body and establishing a new state of equilibrium, so that the patient’s general condition, digestive system, blood system and immune system can be protected to a certain extent, and the purpose of long-term survival with tumor can be achieved. “According to our experience, even if the patient has cancer tumor in his body, if the mental and physical strength is still good, weight is maintained stable, appetite and appetite are good, stool is as usual, sleep is good and other symptomatic elements exist, it means that the patient’s body is in a relatively balanced and stable state of evil and positive, then we should try to maintain this balance and not to break it easily, in order to prolong the survival time with tumor and maintain a better quality of life. ” A 72-year-old patient with pancreatic cancer was confirmed to have hypofractionated adenocarcinoma of the cardia with liver metastasis by dissection, which could not be removed and closed the abdomen, and the patient did not undergo radiotherapy after surgery. Under his guidance, the patient was treated with a combination of Chinese herbal medicine to maintain a balanced and stable state to maintain survival for more than five years, and the lesion remained unchanged on each re-examination. Similar cases are not uncommon in clinical practice. According to Tang Wujun, the efficacy of cancer treatment should not be evaluated purely from tumor shrinkage, but from the balance view of TCM, the overall efficacy level of treatment should be assessed. Chinese medicine against tumor can balance prevention and treatment After years of practice, treatment methods: He pointed out that the role of Chinese medicine treatment in comprehensive treatment of tumor in the elderly is mainly reflected in the following aspects: 1. treatment of low-risk tumor; 2. treatment of residual tumor after surgery, radiotherapy and chemotherapy; 3. treatment of patients who are old, physically weak and have difficulty in withstanding surgery, radiotherapy and chemotherapy due to the insufficiency of major organs such as liver and kidney; 4. post-operative treatment of tumor patients with low risk of recurrence and metastasis. Post-operative treatment of tumor patients with low risk of recurrence and metastasis, etc. For the above-mentioned groups, the use of TCM treatment with lower toxic side effects is a better choice. He believes that for elderly tumor patients in good health condition, active treatment should be considered and should not be too conservative to delay the treatment. The traditional treatment of tumor is easy to hurt the body’s vital energy, leading to deficiency of qi and blood, dysfunction of internal organs and meridians, decrease of immune function, dysfunction of bone marrow hematopoiesis, nausea, vomiting and hair loss, etc. Traditional Chinese medicine treatment should be combined to prevent or correct the imbalance of the body. Tang Wujun said, “Chinese and Western medicine tumor treatment can divide and cooperate, with one side effectively killing tumor cells and the other side actively maintaining the balance of the body’s internal environment.” Nowadays, based on the relationship between the “internal deficiency theory” of Chinese medicine and the development of tumors in the elderly, Tang Wujun has proposed five survival principles to actively prevent the occurrence of tumors: First, to eliminate or avoid the long-term effects of external cancer-causing factors on the human body. For example, smoking, alcohol consumption, ionizing radiation, chemical carcinogens and bad dietary habits. Secondly, adjust the internal environment of the body, enhance the body’s ability to fight cancer, adhere to physical exercise and strengthen physical fitness. Thirdly, regulate the emotion and avoid mental stimulation and trauma, etc. Fourth, timely detect and correct the imbalance of the internal environment of the body. Fifth, actively treat chronic diseases and precancerous lesions that may become cancerous, such as mucosal leukoplakia, hyperplastic mastopathy, esophageal mucosal epithelial hyperplasia, gastric ulcer in the elderly, atrophic gastritis, intestinal polyp-like adenoma, chronic hepatitis, etc. With the accumulation of experience and further research, Tang Wujun is more and more convinced that the organic combination of Chinese medicine and Western medicine treatment, based on the balance concept of Chinese medicine and guided by the “internal deficiency theory”, can achieve positive results in tumor treatment and the ultimate goal of preventing and reducing the incidence of cancer.
