Long‐term survival of a patient with epidermal growth factor receptor (EGFR)‐mutant non‐small cell lung cancer (NSCLC) and untreated multiple brain metastases treated with zorifertinib: A case report

Abstract

Abstract Brain metastases (BM) are common in patients with epidermal growth factor receptor (EGFR)‐mutant non‐small cell lung cancer (NSCLC) and confer poor prognoses. Zorifertinib (AZD3759), an EGFR‐tyrosine kinase inhibitor (TKI) with high blood‐brain barrier penetration, has previously demonstrated promising systemic and intracranial antitumor activity in phase 1–3 studies. This is the first report of a patient with EGFR‐mutant (exon 21 L858R) NSCLC and symptomatic untreated multiple BM who achieved a long overall survival (OS) of more than 65 months after sequential treatment with zorifertinib and a third‐generation EGFR‐TKI. This new treatment paradigm offers a new treatment option and deserves further clinical exploration to prolong OS of patients with EGFR‐mutant NSCLC and untreated multiple BM.
