Effect, safety, timing and dose of thoracic radiotherapy plus third-generation EGFR-TKIs as first-line treatment in patients with EGFR-mutated oligo-organ metastatic NSCLC.

ABSTRACT:

Background

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI)-based combination therapy modalities for patients with EGFR-mutated stage IV non-small cell lung cancer (NSCLC) are being investigated. We evaluated the value and safety of third-generation EGFR-TKIs combined with thoracic radiotherapy (TRT) in patients with oligo-organ metastatic, along with the optimal TRT timing and dose.

Methods

We retrospectively enrolled patients with EGFR-mutated oligo-organ metastatic NSCLC who received first-line third-generation EGFR-TKIs from 2018 to 2023. Patients were divided into TKI-alone and TKI+TRT groups according to whether TRT was added. Propensity score matching (PSM) was implemented to decrease bias. The primary endpoint was progression-free survival (PFS
