There are many chemotherapy regimens for lung adenocarcinoma, and the cost of a chemotherapy session varies depending on the regimen used for chemotherapy, and also depends somewhat on whether the drug used for chemotherapy is an imported drug or a domestic drug. Usually a chemotherapy regimen of pemetrexed plus cisplatin costs about $10,000 per session, while a regimen of docetaxel plus cisplatin, or gemcitabine plus cisplatin costs about $5,000-6,000 per session if domestic drugs are used, while imported drugs are relatively more expensive. Meanwhile, the cost of chemotherapy for lung adenocarcinoma is also determined by whether anti-tumor angiogenic targeted drugs, such as bevacizumab and recombinant human vascular endothelin, are used at the same time. The so-called anti-tumor angiogenic targeted drugs have been shown to improve the effect of chemotherapy for lung adenocarcinoma and play a synergistic role. However, it increases the cost of chemotherapy accordingly, so the cost of chemotherapy for lung adenocarcinoma depends on the composition of the drugs and whether anti-tumor angiogenesis drugs are used, and also depends on the difference between domestic drugs and imported drugs.
