Effect of Endoscopic Bronchial Ultrasound on Outcomes for Stage I Non-Small-Cell Lung Cancer Patients Receiving Hypofractionated Radiotherapy.

Background: In this study we sought to determine if staging endoscopic bronchial ultrasound (EBUS) improves outcomes in stage I non-small-cell lung cancer (NSCLC) patients who received hypofractionated radiation therapy (HFRT).

Patients And Methods: Patients with stage I NSCLC treated with HFRT from 2008 to 2015 were retrospectively identified from 3 affiliated institutions. All patients underwent positron emission tomography/computed tomography staging and a subset of patients received pretreatment EBUS.
