[The current treatment status and future of antibody drug conjugates in HER-2-alteration non-small cell lung cancer].

Non-small cell lung cancer(NSCLC) is one of the major histopathological types of lung cancer, accounting for about 85 percent of all lung cancers. The human epidermal growth factor receptor 2 (HER-2) alteration in NSCLC include gene mutations, gene amplifications, and protein overexpression, and is one of the important driving target. Currently, the treatment options for HER-2 altered NSCLC are still relatively limited, and more effective drugs are urgently needed. Antibody-drug conjugates (ADCs) are a highly efficient combination of targeted monoclonal antibodies and cytotoxic drugs that enable precision therapy for tumors. This paper discusses the current status of treating HER-2 variant NSCLC and the research progress of ADCs in HER-2 variant NSCLC, as well as their development prospects in NSCLC.
