Lung cancer surgery without metastasis, the time needed to take targeted drugs is determined with whether the patient is sensitive to targeted drugs and different genes in the patient’s body.
1. Targeted drugs are mainly used for adenocarcinoma patients with non-small cell lung cancer, such as erlotinib and gefitinib, which target EGFR-TKI with EGFR mutation positivity, and crizotinib and erlotinib, which target ALK re-positivity.
2. Targeted drugs taken by lung cancer patients after surgery have a certain effect on inhibiting the remaining cancer cells, which can control the further development of the disease and reduce the probability of recurrence and metastasis after surgery, thus prolonging the patients’ illness.
However, patients are easy to develop tolerance to the targeted drugs, which usually have no effect after a few months. In addition, patients should be tested for genes before taking targeted drugs, and they can only take targeted drugs if their genes show positive mutations, otherwise they will have no effect.
It is recommended that patients go to the hospital to consult a professional, targeted drug therapy for different patients with different efficacy, should be specific problems analyzed.
