80-year-old man suffered from lung adenocarcinoma . Due to the age of old and underlying diseases that cannot tolerate surgical treatment, the expert team of the Department of Respiratory and Critical Care Medicine of Wuhan Central Hospital reduced the lung tumor of the elderly to the size of a lung nodule through three years of drug treatment. Recently, the doctor performed a microwave ablation of percutaneous right upper lung malignant tumor under CT guidance on the patient, and "scalding" the malignant tumor was killed with a needle.
80-year-old Grandma Wu (pseudonym) came to the Department of Respiratory and Critical Care Medicine of Wuhan Central Hospital for and gasping for treatment three years ago due to chest tightness and gasp. The lung CT scan at that time showed that her right upper lung was space-occupying lesion and was finally diagnosed with lung adenocarcinoma. Because Grandma Wu is old and has basic diseases and cannot tolerate surgery, the expert team of respiratory and critical care medicine repeatedly discussed the treatment plan and finally decided to use drug treatment to reduce the size of the malignant tumor in Grandma Wu's right upper lung, and to undergo bronchoscopy treatment when the tumor shrinks to the size of the lung nodule.
In the following years, Grandma Wu came to the hospital for regular review, and the expert team of respiratory and critical care medicine did her best to guide and monitor the elderly’s dosage and physical condition. After this National Day, during Grandma Wu’s re-examination, Wang Liangchao, deputy chief physician of the Department of Respiratory and Critical Care Medicine, found that the previous malignant tumor had shrunk to the size of a lung nodule after three years of drug treatment. After further examination, Grandma Wu's physical condition also met the conditions for percutaneous ablation treatment.
Half a month ago, Deputy Chief Physician Wang Liangchao performed a microwave ablation of percutaneous right upper lung malignant tumor under CT guidance for Grandma Wu. Under the precise positioning of CT, the microwave ablation needle was directly inserted into the tumor site through the skin, and the tumor cells were coagulated and necroticized by local heating, just like implanting a small microwave oven into the tumor, "scalding" the malignant tumor in a short time, achieving the same effect as surgery. During the operation, Grandma Wu complained and her vital signs were stable. The day after the operation, Grandma Wu was not feeling well after the operation, and was discharged from the hospital on the third day after the operation.
, director of the Department of Respiratory and Critical Care Medicine, Hu Yi, introduced that microwave ablation is a micro-innovative technology for the treatment of solid tumors in recent years. With the help of imaging technologies such as CT and ultrasound, the ablation needle is directly pierced to the tumor site. The microwave energy emitted by the needle quickly heats up in the tumor under the precise control of the instrument. When the temperature rises to about 60-80 degrees, the protein of cancer cells can be denaturated and coagulated, resulting in irreversible necrosis, thereby achieving the purpose of "scalding" cancer cells.
