Tracheo-bronchial adenoid cystic carcinoma: A retrospective study.

摘要: OBJECTIVES Adenoid cystic carcinoma (ACC) of the trachea and bronchus is rare, representing 1% all respiratory tract cancers. We presented our experiences in treating tracheal-bronchial ACC results long-term surveillance. METHODS conducted a retrospective study tracheo-bronchial ACC. From 2009 to 2014, 42 patients department. All them received surgical resection and adjunctive therapy. RESULTS R0 resections were achieved 33 patients, whereas 15 whose lesions spread outside lumens. Nine had R1 followed by radiation chemotherapy. The 5 year survival rate group showed no difference compared group, but disease-free extra-lumenal invasion (ELI) non-ELI (P = 0.0357 < 0.05), although was seen overall these two groups. CONCLUSIONS rare low-to-moderate grade malignant tumor. When over risky or may cause mortal complication, with adjunctive therapy acceptable for obtain promising prognosis, pathological ELI an adverse prognostic indicator.
