Genetic testing is widely used in some malignant tumors, mainly to guide the application of targeted drugs. The cost of targeted diagnosis and treatment should also be determined according to the disease and the type of targeted drugs selected. For example, lung adenocarcinoma, if EGFR has gene mutation, Iressa or Trocquer can be used. This fee is also different. Iressa costs about 2000 yuan per box, and a course of treatment may cost 10000 yuan.

There are also some malignant tumors that can be treated by targeted therapy without genetic testing. For example, apatinib, a small molecule multi-target targeted drug, can be used for the diagnosis and treatment of advanced gastric adenocarcinoma, and the cost is about 7000-8000 yuan/course.

Precautions:

Pay full attention to the adverse reactions of drugs: Generally speaking, the adverse reactions of molecular targeted drugs are relatively light. But when the drug is used for a long time, some new adverse reactions may appear. And targeted drugs may have some special or rare adverse reactions with serious consequences. For example, bevacizumab may aggravate bleeding and delay wound healing, while EGFR-TK may cause rare interstitial pneumonia.

Although molecular targeted diagnosis and treatment is safe, its mechanism of action and treatment of adverse reactions are different from those of cytotoxic drugs, and the mechanism of action and adverse reactions of each kind of drugs are very different. Some side effects will endanger the lives of users, so we must learn more about the relevant knowledge, carefully observe the drug reactions and review them regularly.
