Progress in clinical research of targeted drugs for HER2 positive non-small cell lung cancer
Lung cancer has become the leading cause of cancer death worldwide.Non-small cell lung cancer(NSCLC)accounts for 85%of lung cancers.Human epidermal growth factor receptor 2(HER2)-positive NSCLC is highly aggressive and has a high risk of recurrence and death.Targeted therapy for HER2-positive NSCLC has become a research hotspot.The existing targeted drugs mainly include tyrosine kinase inhibitors,monoclonal antibodies,antibody-drug conjugates,bispecific antibodies,and antibody-radionuclide conjugates.However,there is still no standard treatment recommended by clinical guidelines for HER2-positive NSCLC.This article reviews the latest clinical research results of targeted therapy for HER2-positive NSCLC.
