The life span of targeted therapy ranges from 1-5 years, and can even reach more than 10 years, which needs to be determined according to the type of tumor gene mutation, type of drug, sensitivity and so on. Targeted therapy is an important means of cancer treatment in recent years, which can effectively prolong the survival cycle of patients and control the condition. However, the suitable drugs and sensitivity of each patient are different, so the survival cycle of patients is also different, but most of them remain between 1-5 years, and some of them can even reach more than 10 years. If the patient’s sensitivity to the targeted drugs is high, the treatment effect is more prominent, then it can control the disease well and extend the survival cycle to five years; however, if the drug is not sensitive or there is no suitable drug, then the survival cycle will be relatively shorter, and it may be only a few months or a year or so.
