The cost of targeted therapy for stomach cancer patients ranges from several thousand dollars to tens of thousands of dollars, and the cost varies among different drug types, different manufacturers, different regions and different hospitals. Because of the different types of stomach cancer, the required targeted drugs are not the same, and the price is not the same; moreover, even for the same type of stomach cancer, the patient’s physical condition, the pre-treatment program is different, and the patient’s targeted drugs are not the same, so the specific cost will have a big difference. Taking trastuzumab as an example, it may need about 30,000 dollars, but in different regions with different drug reimbursement scope, there will be a gap in the cost that patients need to pay. In addition, the price difference between domestic and imported drugs for targeted treatment of gastric cancer is also relatively large, so you can consult your doctor for details of the specific costs. Different reimbursement policies in different regions will also lead to the difference in the final cost.
