Background: Adenoid cystic carcinoma of the lung grows gradually, and spreads along the bronchial wall, often requiring tracheobronchoplastic procedure during surgery; however, incomplete resection occasionally occurs due to positive surgical margins. To avoid incomplete resection, effort should be exerted to confirm the extent of airway invasion of the tumor before surgery. Herein, we present the utility of combined treatment with bronchoscopic electrocautery wire snare for the endobronchial tumor prior to sleeve lobectomy with curative resection for patients with adenoid cystic carcinoma of the lung.
Case presentation: A 56-year-old woman experienced a persistent cough 6 months prior. On an annual medical checkup, an abnormal lung shadow was noted. Chest computed tomography (CT) scan demonstrated right middle lobe atelectasis, and a round tumor shadow at the orifice of the right middle lobe bronchus, which protruded into the right intermediate bronchus, was observed. On bronchoscopy, a pedunculated endobronchial tumor in the intermediate bronchus was shown, and the middle lobe bronchus was completely obstructed. Initially, tumor resection via bronchoscopy was performed using an electrocautery wire snare under general anesthesia, and the tumor was pathologically diagnosed as adenoid cystic carcinoma of cT1aN0M0 stage IA. After tumor resection, the extent of tumor progression in the airway was assessed; subsequently, the patient underwent elective right middle sleeve lobectomy and lymphadenectomy. She survived without recurrence 7 years after surgery.
Conclusion: We present a useful combined treatment strategy of bronchoscopic electrocautery wire snare prior to sleeve lobectomy for patients with endobronchial adenoid cystic carcinoma of the lung.
