The treatment cost of lung adenocarcinoma is related to the treatment method, hospital level, area and other factors, usually ranging from 50,000 to 500,000 dollars. If lung adenocarcinoma is in situ when it is diagnosed, which is an early stage tumor, it can be removed by surgery, at this time, the cost may range from 40,000 to 80,000 yuan, and the cost varies greatly in different regions, surgical methods and other costs. If the tumor is in advanced stage at the time of diagnosis, the treatment options include chemotherapy, radiotherapy, targeted therapy, immunotherapy and other methods. The cost of each treatment method varies widely. The cost of chemotherapy involves hospitalization fees, chemotherapy drugs, examination fees, etc. Generally, chemotherapy is required 4 to 6 times, and the cost is about 3,000 to 4,000 yuan each time, with a total cost of about 12,000 to 24,000 yuan for one cycle. The cost of radiotherapy is related to the way of radiotherapy (primary intensity-modulated radiotherapy, ordinary radiotherapy), the level of hospital and the number of times. Generally speaking, if radical radiotherapy is performed for lung adenocarcinoma, it takes about 30 to 40 times, and the cost ranges from 200 to 900 yuan each time, and the cost will increase if there are metastases. The total cost ranges from 6,000 to 36,000 yuan. Targeted drug therapy is suitable for patients with clear cancer-causing sites, and the cost of each type of targeted drug ranges from 2,000 to 30,000 yuan per month. The cost of targeted drug therapy varies according to the cost of different targeted drugs. At present, immune detection point inhibitors represented by anti-PD-1 and PD-LI monoclonal antibody have entered the clinical first-line and second-line treatment, and the cost required for one course of treatment ranges from about 10,000 to 30,000 yuan. Therefore, the treatment cost of lung adenocarcinoma varies greatly, mainly depending on the treatment method used, and it is recommended to consult the attending physician according to one’s own situation.
