Identifying factors causing failure of nodal staging by endobronchial ultrasound-guided transbronchial needle aspiration in non-small cell lung cancer.

ABSTRACT:

Background

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is recommended for nodal staging in non-small cell lung cancer (NSCLC). Although this method may rarely fail, reports on the causes are few. We therefore retrospectively investigated the factors causing failure of nodal staging by EBUS-TBNA.

Methods

Consecutive patients who underwent EBUS-TBNA at National Cancer Center Hospital between January 2017 and December 2020 for systematic nodal staging in NSCLC were extracted. The nodal stages at diagnosis including EBUS-TBNA and at treatment were investigated separately, and unmatched cases were defined as failures. Factors associated with them were explored while dividing the cases into punctured and not-punctured groups.
