INTRODUCTION: Electromagnetic navigation bronchoscopy (ENB)-guided pleural dye marking is useful to localize small peripheral pulmonary nodules for sublobar resection.
OBJECTIVE: To report findings on the use of ENB-guided dye marking among participants in the NAVIGATE study.
METHODS: NAVIGATE is a prospective, multicentre, global and observational cohort study of ENB use in patients with lung lesions. The current subgroup report is a prespecified 1-month interim analysis of ENB-guided pleural dye marking in the NAVIGATE United States cohort.
RESULTS: The full United States cohort includes 1215 subjects from 29 sites (April 2015 to August 2016). Among those, 23 subjects (24 lesions) from seven sites underwent dye marking in preparation for surgical resection. ENB was conducted for dye marking alone in nine subjects while 14 underwent dye marking concurrent with lung lesion biopsy, lymph node biopsy and/or fiducial marker placement. The median nodule size was 10 mm (range 4-22) and 83.3% were <20 mm in diameter. Most lesions (95.5%) were located in the peripheral third of the lung, at a median of 3.0 mm from the pleura. The median ENB-specific procedure time was 11.5 minutes (range 4-38). The median time from dye marking to resection was 0.5 hours (range 0.3-24). Dye marking was adequate for surgical resection in 91.3%. Surgical biopsies were malignant in 75% (18/24).
CONCLUSION: In this study, ENB-guided dye marking to localize lung lesions for surgery was safe, accurate and versatile. More information is needed about surgical practice patterns and the utility of localization procedures.
