The Role of Brain Radiotherapy before First-Line Afatinib Therapy, Compared to Gefitinib or Erlotinib, in Patients with EGFR-Mutant Non-Small Cell Lung Cancer.

ABSTRACT:

Purpose

Brain metastasis is common in patients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) at initial presentation. A previous study showed that brain radiotherapy (RT) before first-generation (first-G) EGFR-tyrosine kinase inhibitor (TKI) therapy is associated with longer overall survival than TKI therapy alone. However, there is no data regarding the role of additional brain RT before afatinib therapy.

Materials and methods

Between October 2014 and June 2019, EGFR-mutant NSCLC patients with brain metastases who started first-G EGFR-TKIs (gefitinib or erlotinib) or afatinib as first-line therapy were retrospectively analyzed. This study compared overall survival and intracranial progression-free survival (PFS) between patients who
