Targeted therapy is a major therapeutic tool based on the molecular biology and cell biology of tumor, using the specific structural molecules of tumor tissues or cells as targets, and using certain drugs that can specifically bind to these target molecules to achieve the purpose of direct treatment or directed treatment, which has better molecular and cellular selectivity, can efficiently and selectively kill tumor cells and reduce the damage to normal tissues. Therefore, molecular targeted therapy is also called “biological missile”. What are the targeted therapeutic drugs for lung cancer? 1.Epidermal growth factor receptor tyrosine kinase inhibitors such as Erythropoietin, Troche, Kemena. 2. Anti-tumor vascular drugs such as bevacizumab (Anvitin), recombinant human vascular endothelial inhibitor (Endo), etc. These drugs inhibit the growth of tumor blood vessels and cut off the nutrient supply of tumor. 3.Epidermal growth factor receptor monoclonal antibody Cetuximab (Epiduo) What are the advantages of molecular targeted therapy? 1.Simplicity: The treatment is very simple. 2.Safety: simple and convenient operation, safe and reliable. 3, less damage: targeted therapy, the drug is mainly concentrated in the tumor body, the human body is basically no toxic side effects and adverse reactions to normal tissue cells. 4.Minimally invasive: the patient’s adaptation is wide and easy to accept. 5.High efficiency: High concentration of drugs plus controlled action time, thus making the treatment effect greatly improved. 6, repeatable treatment. 7.It can be combined with any one or multiple tumor treatment methods, which reflects the principle of comprehensive tumor treatment.
