N2 - Objective: Tracheobronchial adenoid cystic carcinoma is a rare, slow-growing malignancy with a considerable propensity for local extension that may require complex airway resection to achieve tumor-free margins. The objective of this study was to assess whether our experience supports complex airway resection for tracheobronchial adenoid cystic carcinoma. Methods: Consecutive patients who underwent curative resection for tracheobronchial adenoid cystic carcinoma at our institution between 1970 and 2019 were included retrospectively and classified as having had complex or standard resection. Complex surgery included total tracheal replacement, associated esophageal resection, pneumonectomy, total laryngectomy with tracheal resection, and carinal resection. Standard surgery included tracheal resection, bronchoplastic resection, lobectomy, and bilobectomy. We obtained data from medical records, referring physicians, patients, relatives, and public death records. Results: Of 59 included patients, 38 had complex and 21 had standard surgery. All 4 (6.8%) patients who died postoperatively had undergone complex surgery. Postoperative morbidity was 32.2% overall and was significantly higher after complex surgery (P = .043). Overall 5- and 10-year survival rates were 81.5% and 60.2%, with no significant differences between groups (P = .31). By univariate analysis, T4 tumor and microscopically detectable tumor in the operative specimen margins and gross tumor in the operative specimen margins were associated with poorer survival (P < .05). In the subgroup with microscopically detectable tumor resection, survival was significantly better with adjuvant radiotherapy (P < .05). Conclusions: Complex resection for extended tracheobronchial adenoid cystic carcinoma may achieve local control and satisfying long-term survival. However, this demanding procedure is associated with high postoperative morbidity and mortality rates. Because adjuvant radiotherapy improved outcomes after resection resulting in microscopically detectable tumor in the operative specimen margins, expected outcomes after resection with no detectable tumor in the margins must be compared to those after resection resulting in microscopically detectable tumor in the margins plus radiotherapy, according to the operative risk.
