The research and application of
millimeter wave (MMW) technology in the field of medical biology has developed rapidly around the world and has received widespread attention from the academic community.
In addition to being used in non-tumor diseases such as digestive tract diseases, nerve damage repair, antibacterial and anti-inflammatory, and wound healing, MMW has become a new treatment for tumors or an effective auxiliary treatment for tumor radiotherapy and chemotherapy. There are many literature reports on cancer pain relief and treatment.
Dr. Beneduci's study believes that low-power MMW dependent on frequency and radiation time has an inhibitory effect on the proliferation of RPMI7932 human melanoma cell line. Dr. Logani and other studies have shown that MMW radiation has an inhibitory effect on tumor metastasis.
The severity of acute radiation dermatitis is closely related to the dose size, irradiation range, total dose, type of radiation, and tolerance of normal tissues or organs. The changes in tissue cell metabolism, structure, and function caused by radiation and high temperature are essentially different. It is also different from skin damage caused by general infection. The use of antibiotics or ointments for treatment is not ideal.
The results of this study show that the total effective rate of the MMW group in the treatment of acute radiation dermatitis is 98.3%. The total effective rate of the control group was 85.4%, and the difference between the two groups was significant (P<0.05). In grade I dermatitis, the effective rate of both groups was as high as 100%, but the healing speed was different. The healing time of the
MMW group was significantly shorter; in grade II and III dermatitis, the effective rate of the MMW group was higher than that of the control group, and the healing time was shorter than that of the control group; in grade IV dermatitis, the effective rate of the MMW group was significantly higher than that of the control group, while the healing time of the control group was significantly prolonged, and the ineffective rate was as high as 50.0%, and the patients had to undergo surgical treatment. The use of MMW to treat acute radiation dermatitis shortens the wound healing time and achieves good therapeutic effects, especially in the treatment of grade II, III, and IV dermatitis (42/43, 97.67%).
MMW resonates when acting on these biomacromolecules and biomembranes. It can rearrange the microstructure of the tissue, change the activity of proteins, amino acids, and enzymes, and thus regulate the metabolism and function of cells. This study combines the physical properties of millimeter waves. MMW has a short wavelength and mainly acts on the skin and subcutaneous tissue. MMW resonates with human skin and subcutaneous tissue to produce biological effects and therapeutic effects, promoting the healing of dermatitis. MMW treats radiation dermatitis of the neck, retains the anatomical morphology and physiological function of the neck, reduces the patient's pain, and improves the quality of life.
