RESUMO
Despite the success of various cancer therapies on patient survival, these treatments can have negative side effects, particularly severe damage to the respiratory system. Given the rise in respiratory-associated illnesses in response to cancer treatment, we urge the field to consider a new discipline referred to as 'oncology-respirology' (or onco-respirology).
RESUMO
Human epidermal growth factor receptor 2 (HER2) is a transmembrane glycoprotein receptor with intracellular tyrosine kinase activity. It is generally considered as a poor prognostic marker. Targeted therapies, such as small molecule tyrosine kinase inhibitors (TKIs), showed limited efficacy in HER2-mutant advanced nonsmall cell lung cancer (NSCLC). In the 2023 National Comprehensive Cancer Network guidelines for NSCLC, antibody-drug conjugate trastuzumab emtansine is recommended for the treatment of HER2-mutant lung cancer. However, this medication is currently not approved in certain regions. So it is necessary to explore alternative treatment options for HER2-mutant NSCLC patients. In our study of a patient with HER2 exon 20 insertion lung adenocarcinoma who had previously failed multiple epidermal growth factor receptor (EGFR)-TKI treatments, we discovered that sunvozertinib could stabilize the patient's condition, achieving a progression-free survival of 87 days. This is a novel finding that may provide new treatment options for HER2 exon 20 insertion patients who have failed TKI therapy.
