Information

Materials and methods

Our hospital used millimeter waves to treat 30 patients with cancer pain, including 19 males and 11 females; aged 20-73 years, with an average of 52 years; 9 cases of lung cancer, 7 cases of gastrointestinal tumors, 4 cases of urinary system tumors, esophageal cancer and There were 3 cases of breast cancer each, 2 cases of soft tissue sarcoma, 1 case each of nasopharyngeal carcinoma and malignant schwannoma; 9 cases were stage Ⅲ and 21 cases were stage Ⅳ in TNM staging. 18 cases have been treated surgically. All 30 patients had the following conditions: ①Pain caused by cancer; ②Generally good condition, no cachexia; ③Karnof sky score above 70 points. Pain was caused by local invasion of the primary tumor in 9 cases, metastasis in 19 cases, and surgical incision pain in 2 cases. The pain was in 8 cases of chest wall, 9 cases of thoracolumbar spine, 5 cases of abdominal cavity, 5 cases of pelvis, 2 cases of skull, and 1 case of right upper limb. Using the 4-level pain classification method, level 0 means no obvious pain, no effect on sleep, free movement, no painful expression; level I has slight pain, tolerable, slight impact on sleep, free movement, no painful expression; level II There is severe pain, which is tolerable, has a greater impact on sleep, is slightly restricted, and has painful expressions; Grade III has severe pain, which is unbearable, has a serious impact on sleep, has limited movement, forced posture, and

painful expression, moaning. Among the cases in this group, there were 14 cases of grade II pain and 16 cases of grade III pain.

Using millimeter wave therapy instrument, frequency 42.5GHz, wavelength 7.1mm, output power density 8-15mW/cm2. The radiation head is placed on the surface of the acupoint skin, once a day, 30min, 5 times a week, 4-20 times, an average of 10.4 times. The principle of acupoint selection is to select acupoints along the meridian, a combination of acupoint selection based on syndrome differentiation and acupoint selection for local pain points (Ashi point). Generally, back Shu points plus Hegu or Zusanli and Ashi points are used. For those taking analgesics before treatment, keep the original dose, and gradually reduce the dose after the millimeter wave treatment is effective for analgesia, so that the drug is completely stopped.

The degree of pain relief is divided into 5 grades: grade 0 no relief, grade Ⅰ mild relief, and the efficacy is evaluated as invalid; grade Ⅱ moderate relief, the effect is effective; grade Ⅲ is obviously relieved, and grade Ⅳ is completely relieved, and the effect is markedly effective.

Results and discussion

The total effective rate of pain relief in 30 cases was 63%, of which 7 cases were markedly effective, 12 cases were effective, and 11 cases were ineffective. Pain is prescribed after 1 treatment

2 cases started remission, 19 cases showed remission within 10 treatments, and the treatment took effect on an average of 4 times. After the results were effective, the dosage of analgesics was gradually reduced. The painkillers were completely stopped after an average of 9 treatments, and 12 cases were effective. After treatment, the level of painkillers and the dosage of painkillers were reduced. It shows that millimeter waves have a good effect on cancer pain, and no obvious side effects were observed in this group of patients.

Millimeter waves are electromagnetic waves with a wavelength of 1 to 10 mm, and the corresponding frequency range is 30 to 300 GHz. It belongs to the highest end of the microwave band and is similar to the natural frequency of mammalian tissue at 50 GHz. In recent years, the biological characteristics of millimeter waves have been continuously discovered, especially the application of non-thermal biological effects and long-distance effects in medicine has been gradually promoted to treat a variety of diseases, promote wound healing and burn recovery, and achieve better results ( 1]. In the treatment of tumors, it also plays its unique role. Millimeter waves can not only control the pain of advanced cancer patients, but also inhibit the growth of cancer cells [2], regulate the body’s immune function [1], improve peripheral blood picture [3], and reduce Side effects of radiotherapy and chemotherapy [3], improve the quality of life of cancer patients.

All patients in this group had grade Ⅱ and grade Ⅲ pain. After millimeter wave treatment on average 10 times, the effective rate was 63%, and 23% of the patients achieved complete relief. The analgesic mechanism of millimeter wave has not yet been clear. From the perspective of traditional Chinese medicine, the principle of selecting acupoint during millimeter wave treatment is in line with the meridian theory. Millimeter waves are introduced into the body through resonance to produce energy conversion, which is similar to the theory of acupuncture and analgesia. Follow the meridian route to regulate the patient's neuroendocrine and activate the pain modulation system in the body to achieve analgesic effect. Modern medical research has proved that millimeter waves have inhibitory and killing effects on cancer cells [2], reducing tumor burden and disappearing pain. Millimeter waves can also change the properties of blood rheology, strengthen local tissue metabolism, promote inflammation absorption, eliminate swelling, and relieve pain [4]. At the same time, it can promote the excretion of pathology and metabolites, accelerate the excretion of local pain-causing substances, and relieve pain [1]. In short, millimeter waves have a positive effect on cancer pain, and its mechanism needs further study. As an important method of palliative treatment of advanced cancer, millimeter wave is worth promoting.
