Advanced Diagnostic Bronchology- Techniques for the peripheral lung nodule

Bronchoscopy First Reason #1 - Pneumothorax The pneumothorax rate for bronchoscopy techniques = 1.5% with 0.6 % requiring chest tube. J Wang Memoli et al. Meta-Analysis of guided bronchoscopy for the evaluation of the pulmonary nodule. CHEST 2012; 142(2): The pneumothorax rate for CT guided TTNA is 27% with 5% requiring chest tube. Huanqi L et al.

Bronchoscopy First Reason #2- mediastinal staging

The only time you don’t do EBUS is when a patient has a lung nodule (<3 cm) in the peripheral 1/3rd of the lung with negative CT and negative PET. Eur J Cardiothorac Surg May;45(5): Revised ESTS guidelines for preoperative mediastinal lymph node staging for non-small-cell lung cancer.

Bronchoscopy First Reason #2- mediastinal staging If tumor size > 3 cm – full mediastinal staging is needed (even if CT + PET negative). If tumor (any size) is central – full mediastinal staging is needed (even if CT + PET negative). If even 1 N1 lymph node is suspected involved – full mediastinal staging is needed. (The new lymph node cut –off is > 0.5 cm.) Eur J Cardiothorac Surg May;45(5): Revised ESTS guidelines for preoperative mediastinal lymph node staging for non- small-cell lung cancer.

EBUS EBUS sensitivity for positive mediastinum is %. Mediastinoscopy 90%. PET 80%. CT 75%. Conventional TBNA 58-78%. Negative Predictive value – EBUS %. Mediastinoscopy 91%. PET %. CT Scan 80-85%.

Lesion < 3cm : EMN

EMN Electromagnetic Navigation uses a board below the patient to generate a magnetic field around the patient’s thorax. Sensors on the patient’s chest and in the bronchoscope are used to match patient’s airway to a CT scan. Once the match happens the computer guides us to the lesion. – Gildea TR et al.

Cryobiopsy

Summary A majority of patients with suspected lung cancer need EBUS/ mediastinal staging. The bronchoscopic yield of peripheral lesions has significantly improved. Exceptions to bronchoscopy first – (a) advanced stage disease (b) non-surgical candidate and (c ) the < 3 cm peripheral nodule with negative PET and CT.
