In non-small cell lung cancer (NSCLC), ADCs are being investigated targeting human epidermal growth factor receptor 2 (HER2), human epidermal growth factor receptor 3 (HER3), trophoblast cell surface antigen 2 (TROP2), Mesenchymal–epithelial transition factor (c-MET), and carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5). This evidence concerns the gene TACSTD2 and non-small cell lung carcinoma.
