EBUS = endobronchial ultrasound; EUS = endoscopy with ultrasound-guided needle aspiration; TBNA = transbronchial needle aspiration.
Strata with ≤ 10 patients were suppressed as per National Cancer Institute policy and are reported as “< 11” to ensure confidentiality. EUS was performed in < 11 patients and was therefore included in the bronchoscopy with TBNA + EBUS category to protect patient confidentiality.
Major resection is anything more than a wedge resection. This is defined as a segmentectomy, lobectomy, pneumonectomy, tracheal resection, or chest wall resection.
