Targeted therapy is a treatment method at the cellular and molecular level that targets a well-defined cancer-causing site (the site can be a protein molecule inside a tumor cell or a gene segment). Corresponding therapeutic drugs can be designed. When the drugs enter the body, they will specifically select carcinogenic sites to combine and act, causing the tumor cells to specifically die without affecting the normal tissue cells around the tumor. Therefore, molecular targeted therapy is also known as "Bio Missile".
Molecular targeted drugs of different categories target different gene targets. Through driver gene detection, it can be found whether there are corresponding gene targets, so as to select suitable targeted drugs for patients in a targeted manner.
