Heat therapy is a kind of green therapy for tumor treatment, because tumor tissues have difficulty in dissipating heat under high temperature, and there is a temperature difference of 5℃～10℃ with normal tissues; while normal cells can tolerate high heat of 42.5℃～43.5℃ for a long time, high frequency oscillating current acts on deep tumor and other tissues of human body, generating endogenous heat to make the inside of tumor reach 43℃, thus killing tumor cells without affecting normal cells, especially It can effectively solve the problem of tumor pain. This is the unique feature of thermotherapy that is different from chemotherapy and radiotherapy. At present, the pain in the advanced stage of tumor causes most patients’ quality of life to be seriously reduced, and they can only rely on large doses of morphine and other opioid drugs to control the pain, which is often worse than death. The introduced extracorporeal high-frequency heat therapy machine, using the principle of heat therapy, has obvious effect on local treatment of tumors, especially it can relieve the pain caused by various tumors. Wang, who lives near the central gate, underwent surgery for left-sided lung cancer, and the indexes were normal after the surgery, but the pain at the surgery site was unbearable and could not be controlled even after taking Tramadol, and then after changing to Meclizine, he could not continue to adhere to it due to the side effects such as dizziness and constipation, and was in abnormal pain and could not sleep at night. After receiving two sessions of heat therapy the pain was significantly relieved and after a course of treatment there was no longer any significant sensation and he is no longer taking pain medication. Heat therapy can be used not only alone but also in combination with chemotherapy. Director Huo introduced that the combination of heat and chemotherapy can increase the concentration of drugs in the tumor and enhance the anti-tumor effect; at the same time, it can reduce the toxic side effects of chemotherapy drugs on the unheated normal tissues; the combination of the two can also help prevent and delay the development of drug resistance. A patient with gastric cancer in Hubei, who developed abdominal metastasis, ascites, abdominal distention and incomplete intestinal obstruction less than one year after surgery, was transferred from an outside hospital after hearing about this technology and underwent two times of abdominal perfusion chemotherapy with heat therapy, which reduced abdominal distention and allowed the passage of stools. The integrated treatment of heat therapy, chemotherapy and Chinese medicine effectively improved the patient’s quality of life with positive results.
