Drug therapy is the main treatment in antitumor therapy. Currently, drug therapy mainly includes chemotherapy, targeted drug therapy, and immunotherapy. The cheaper drugs include fluorouracil, methotrexate, cyclophosphamide, etc. The cost of one treatment cycle can be completed within a hundred dollars. The more expensive drugs for treatment, including liposomal paclitaxel and liposomal adriamycin, cost about$10,000 to$20,000 for one cycle of their treatment regimen. Some drugs are also priced between twice and three times the price difference due to the difference between imported and domestic products. In addition to chemotherapy drugs, the overall price of targeted drug therapy is currently on the high side. The current price of targeted drug use, per cycle, i.e., the cost of using each month, is approximately between 2,000-3,000 yuan and 40,000-50,000 yuan, with some differences in the type of drug, variety and specific domestic and imported drugs, and the price of immunotherapy drugs is currently around 7,000-20,000 yuan per cycle.
