Gastric cancer belongs to a kind of malignant tumor in digestive system, and there is no way to treat it with surgery in the late stage, so if you want to have active anti-tumor treatment, chemotherapy is more commonly used. Generally speaking, the price of chemotherapy needs to be decided according to the drugs used in chemotherapy and the treatment situation. If domestic chemotherapy drugs are used, the cost of one course of treatment is about 6,400 RMB. There may be some differences between different levels of hospitals and different regions, but the overall difference is not too big. If imported drugs are chosen, or if the patient is hospitalized for a longer period of time during chemotherapy because of side effects, the cost will definitely be a little higher. The common side effects of chemotherapy are nausea, vomiting, and myelosuppressive reactions, such as white blood cell decline, anemia, platelet reduction, etc.. If there are more side effects, it is necessary to apply drugs to raise white blood cells and replenish blood, and the cost will be higher.
