Treatment for lung cancer includes surgery, radiotherapy, chemotherapy and targeted therapy, and interventional therapy is an adjuvant treatment for lung cancer. Then what does interventional lung cancer treatment mean? What is it used in the case of lung cancer? In fact, interventional treatment for lung cancer is not something new, it mainly includes bronchoscopic intervention, endovascular intervention and percutaneous intra-tumor intervention, etc. Bronchoscopic intervention includes local cryogenic freezing and high temperature cauterization of tumor (microwave, laser, etc.), endobronchial stent placement for local narrowing of tumor, local radiotherapy for tumor, etc. It mainly aims to reduce local tumor mass or enlarge trachea and bronchus narrowed by tumor obstruction, so as to improve symptoms of dyspnea or repeated obstructive pneumonia. Endovascular intervention mainly involves injecting anti-cancer drugs or putting emboli into the bronchial arteries, which are the nutrient vessels of lung cancer, to block the blood supply of lung cancer, so as to gradually “starve” the lung cancer and make it necrotic. However, since the nutrient blood vessel of lung cancer is also the pulmonary artery, and there are abundant anastomosing branches between bronchial artery and pulmonary artery, it is easy to recanalize and restore blood supply after interventional surgery, and the long-term treatment effect is not good. At present, it is only used in a very small number of patients who are neither willing to undergo surgery, nor radiotherapy and chemotherapy, nor have the financial strength for targeted therapy, and are willing to undergo palliative care. Percutaneous intra-tumor intervention includes intra-tumor injection of anhydrous alcohol or anti-tumor chemotherapeutic drugs and tumor radiofrequency ablation, which also aims to reduce the size of local tumor mass, thus reducing the tumor load, so it is only a local treatment. In summary, no matter what kind of interventional treatment is used, it is a local treatment for lung cancer. Since lung cancer is a systemic disease, especially since about 85% of lung cancers are already in the middle and late stages when diagnosed with distant metastases, you simply cannot rely on the so-called interventional treatment to control the disease. If you or your loved ones are unfortunate enough to have lung cancer, please make sure to seek consultation with a lung cancer specialist who will decide the treatment plan according to the pathological type, growth site, metastasis and general physical condition of lung cancer. Please make sure you do not trust the advice of non-lung cancer specialists, because lung cancer is a special disease and not all doctors know the regular treatment of lung cancer, let alone trusting the treatment advice of non-medical personnel!
