Overview
On endobronchial ultrasound (EBUS) and endoscopic ultrasound, characteristic findings of non-small cell lung cancer include enlarged lymph nodes and local invasion to adjacent bronchial structures and mediastinum. Endobronchial ultrasound is a first-line diagnostic modality for mediastinal staging.
Ultrasound
Endobronchial ultrasound is a first-line diagnostic modality for mediastinal staging.[1][2]
- Endobronchial and endoscopic esophageal ultrasound are mainly used to identify mediastinal metastasis.
- On ultrasound (endobronchial/endoscopic esophageal ultrasound), characteristic findings of non-small cell lung cancer include:
- Enlarged lymph nodes
- Local invasion of adjacent bronchial structures and mediastinum
- Indications for the endobronchial ultrasound:
- Evaluation of lymph nodes and other structures in the mediastinum
- Mediastinal invasion staging
- Plan for management
- Real-time evaluation of structures
The table below summarizes the advantages and disadvantages of both ultrasound modalities, for the diagnostic assessment of non-small cell lung cancer.
Procedure Advantages Disadvantages Endobronchial ultrasound (EBUS) - Direct visualization of lymph node stations.
- Complements endoscopic ultrasound: covers lymph node stations 2R and 4R which are difficult to access by endoscopic ultrasound
- Lower false-negative rate than with blind transbronchial fine needle aspiration and fewer complications
- More invasive than endoscopic ultrasound, few practitioners, but rapidly growing in popularity
Endoscopic ultrasound (EUS) - Least invasive modality
- Uses the esophagus to access mediastinal lymph nodes
- Excellent for staging lymph node metastases
- Useful for station 2L and 4L, L adrenal, celiac lymph node
- Cannot reliably access right sided paratracheal lymph node stations 2 R and 4R
- Accurate discrimination of primary hilar tumors and involved lymph nodes is important
