Safety and efficacy of consolidative stereotactic radiotherapy for oligo-residual EGFR-mutant non-small cell lung cancer after first-line third-generation EGFR-tyrosine kinase inhibitors: a single-arm, phase 2 trial.

ABSTRACT:

Background

Prospective data is limited on the efficacy and safety of consolidative stereotactic radiotherapy (SRT) in metastatic epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) patients harboring oligo-residual disease (ORD) after first-line third-generation EGFR-tyrosine kinase inhibitors (TKIs).

Methods

In this single-arm, phase II trial, 61 patients from two academic centers were enrolled from March 2021 to March 2023. All these patients had metastatic EGFR-mutant NSCLC and harbored ORD after first-line third-generation EGFR-TKIs. Consolidative SRT was performed and EGFR-TKIs were not held during SRT. The primary endpoint was progression-free survival (PFS) and the secondary endpoints included overall survival and treatment-related advers
