- W2238678747 abstract "BackgroundPrimary tracheal cancer comprises a heterogeneous and rare group of neoplasms. Management of patients with primary tracheal carcinoma at our institution has improved in recent years.MethodsThis retrospective review included patients with localized primary tracheal adenoid cystic carcinoma treated surgically at our institution between January 1995 and December 2014. Patients were classified according to the timing of first operation: “early years” operation was performed between January 1995 and December 2002, and subsequent “recent years” operation was associated with improved management and a focus on early diagnosis.ResultsThe proportion of patients with tracheal malignancy who underwent operation for adenoid cystic carcinoma increased with time. Patients in the recent group were significantly younger than those in the early group at diagnosis (49.3 ± 7.8 years versus 45.7 ± 9.4 years; p = 0.042), and the resected tumor size and tracheal lengths tended to be smaller (28.2 ± 7.6 mm versus 30.3 ± 7.0 mm; p = 0.161) and shorter (32.1 ± 7.7 mm versus 34.4 ± 6.7 mm; p = 0.123). The use of postoperative radiotherapy in patients with R1 resection was also managed more effectively in the recent group compared with the early group (90.6% versus 65.0%; p = 0.009). Five- and 10-year overall survival rates in the early and recent groups were 86.4% and 90.8%, and 31.8% and 61.2%, respectively (p = 0.084), and the corresponding 5- and 10-year disease-free survival rates were 39.7% and 75.3%, and 9.9% and 21.2%, respectively (p = 0.025).ConclusionsThere have been improved outcomes of adenoid cystic carcinomas. Early diagnosis, experienced surgical treatments, and postoperative adjuvant radiotherapy for patients with positive margins may contribute to the improved survival of patients with primary tracheal adenoid cystic carcinoma.
