1.Enhance the efficacy of radiotherapy: The reasonable application of TCM can increase the sensitivity of malignant tumor cells to radiotherapy. For example, for lung cancer patients, the method of benefiting lung qi and nourishing lung yin should be applied; for bone tumor patients, the combination of radiotherapy with drugs that tonify kidney yin and kidney yang is more suitable; for esophageal cancer patients, the method of strengthening spleen and stomach, broadening chest and lowering qi should be applied. For esophageal cancer patients, applying methods to strengthen the spleen and stomach, broaden the chest and lower the qi is helpful to increase sensitivity of radiotherapy. (1) Patient Zhang Moumou, male, 67 years old, was diagnosed as squamous carcinoma of upper middle esophagus by gastroscopy and biopsy in October 2005 due to poor feeding, and underwent radiation therapy in cancer hospital. The patient’s pulse was stringent and slippery, the tongue was thin and dry, and the front light was flaking. The patient was identified as having a deficiency of spleen and fluid and internal heat toxicity. It is generally believed that radiation is a fire-heat poisonous evil attacking the human body, which can easily burn the yin fluid and cause damage to yin and fluid, head and neck tumors are more likely to cause dry mouth and throat, some patients will be accompanied by low fever, heart trouble, night sweating and other symptoms of internal heat of yin deficiency. cooling the blood and benefiting the qi and nourishing the blood, which can reduce the damage to the blood system such as leukocyte and platelet reduction. (2) Patient Yuan Moumou, male, 57 years old, in April 2007, due to cough and hemoptysis, chest X-ray and chest CT in Chest Hospital suggested left lung nodules, widened mediastinum, enlarged mediastinal lymph nodes, performed fibrinoscopy and biopsy, diagnosed as central type squamous carcinoma of the left lung, stage IIIB, inoperable, instead, systemic chemotherapy and local radiation therapy, and sought medical consultation in November 2007, the patient felt easily weak, with The patient’s appetite was average, no obvious chest pain, slightly hard stool, fine pulse, thin white dry tongue coating, the diagnosis was that the lung was deficient in both qi and yin, and phlegm was concentrated in the lung. The patient took 21 doses of the medicine, the low-grade fever was relieved, the cough was relieved, the appetite improved, and the spirit improved. Radiation pneumonia is a common complication after radiation therapy for thoracic tumors, which directly affects the effect of radiation therapy and the quality of survival of patients. We believe that it is caused externally by radiation exposure, which is the evil of heat and toxicity, and internally by deficiency of positive energy, injury to yin and depletion of qi, and internal stagnation of blood. The heat toxin injures the lung, the lung is hot and leafy, the purification is lost, and the qi reverses upward. Clinical evidence of deficiency is based on deficiency of lung spleen and yin. Treatment is to benefit Qi and nourish Yin, moisten the lung and strengthen the spleen. (3) A 68-year-old female rectal cancer patient, after surgery and radiotherapy, with urgency and heaviness, stool 5-6 times/day, rotten and mucus, often with fresh blood, sometimes prolapse, appetite is still okay, slightly feeling bloated, given to strengthen the spleen and soften the liver, promote the middle qi, cool the blood and stop bleeding drug treatment, after one month, the patient felt the urgency and heaviness significantly improved, stool 2-3 times/day, basically formed, blood in the stool occasionally, the amount is small, prolapse Basically, on the basis of the above, the patient should continue to take drugs for clearing heat and detoxifying, softening and dispersing knots, in order to prevent tumor recurrence and metastasis. Rectal cancer or pelvic tumor need to use radiation therapy, and radiation enteritis is inevitable, the patient often has urgent after heavy, stool times increase, stool with mucus or fresh blood, clinical application of clearing heat and cooling blood, spleen and Qi drugs and formulas have better results. In addition, radiotherapy can also cause radiation dermatitis, radiation cystitis, etc. The above-mentioned adverse reactions are not given only after the patient has symptoms, but should be preventatively intervened before radiation therapy is implemented, and the disease should be prevented from continuing to gradually worsen in radiotherapy, from mild inflammatory exudation into severe pulmonary fibrosis or chronic enteritis, etc. Combination with immunotherapy 1.Increase the possibility of achieving efficacy with immunotherapy: At present, among solid tumors, kidney cancer and lymphoma can achieve efficacy with immunotherapy, which can increase the efficacy if combined with Chinese medicine treatment, we often use methods to nourish kidney yin and warm kidney yang, such as Erxian Tang, combined with drugs to clear heat and detoxify and soften hard nodes. 2, reduce the side effects of immunotherapy: such as the application of interferon, interleukin 2 and other immune agents caused by fever; application of immune agents, most patients will have flu-like symptoms, chills, fever, generalized aches and pains, weakness, and even loss of appetite, etc. On the one hand, non-steroidal antipyretic and analgesic drugs can be used in advance, on the other hand, Chinese medicine with the regulation of Ying and Wei, beneficial Qi and detoxification drugs, can alleviate the immunotherapy as soon as possible side effects of immunotherapy. In addition to the symptomatic treatment of the adverse reactions during the use of the above mentioned drugs, we should pay more attention to certain Chinese herbs such as Astragalus, Radix Codonopsis, Ganoderma lucidum, Acanthopanax, Ginseng, Rhizoma albiflorum, Fritillaria, Dandelion, and Rhizoma sanguinarum, which have their own immunomodulatory effects and avoid the occurrence of tumor immune escape by improving the patient’s general condition and sounding the patient’s immune mechanism.
