What good treatment method does the elderly lung cancer have in the late stage?

Hello, I suggest interventional therapy. Interventional treatment of lung cancer is percutaneous femoral artery puncture and bronchial artery perfusion chemotherapy. This treatment method is mainly used for patients who can't operate and have serious systemic chemotherapy response. The specific treatment method is to insert a special fine catheter through the femoral artery at the root of the thigh under local anesthesia, send the catheter into the bronchial artery supplying blood to the lung cancer focus under fluoroscopy, and then inject anticancer drugs into the human body after angiography. The advantages of intra-arterial infusion chemotherapy are as follows:

(1) has the advantages of less total dose, less systemic toxicity and quick response. At present, this treatment method has been widely used in clinic, but it should be considered comprehensively because of its certain complications.

(2) Transcatheter arterial infusion can reduce the binding of anticancer drugs with plasma protein, increase the concentration of free drugs, improve the cytotoxicity of anticancer drugs, and help to kill tumor cells.

(3) It can effectively increase the local drug concentration of tumor, which is 2-6 times or more higher than that of intravenous administration. When the local drug concentration is increased by 1 fold, the number of tumor killer cells can be increased by1fold, which is a logarithmic increase.

(4) In the treatment of advanced lung cancer, perfusion of anticancer drugs through bronchial artery can not only act on local tumor, but also enter the metastatic focus of hilum and mediastinum, thus eliminating the near metastasis of lung cancer and inhibiting the further spread of tumor.
