ASTER—another flower in the diagnostic field of lung cancer?

Mediastinal staging of patients with lung cancer is used to avoid futile thoracotomies. Endoscopic, esophageal and bronchial ultrasound procedures are methods to identify involved lymph nodes. The ASTER study indicates that the sensitivity of these new techniques is high, reducing the number of futile thoracotomies and improving outcomes when combined with mediastinoscopy.
