目的：回溯性比較源發於上下呼吸道的腺樣囊狀上皮癌放射治療後的追蹤結果。 材料與方法：回溯性追蹤1987 到2012 年之間，12位確定診斷為呼吸道腺樣囊狀上皮癌的病人。 從病歷中取得手術的方式與放射治療的內容，並且比較其整體存活率（OS），與無進展存活率 （PFS）。 結果：在上下呼吸道的比較中，不論是整體存活（p= 0.177）或無進展存活（p= 0.264）都沒有 顯著的差異。然而當比較個案接受手術切除與否與存活的關係時，有接受手術者不論在整體存 活（p= 0.005）或無進展存活率（p= 0.016），都優於未接受手術者。 結論：呼吸道腺樣囊狀癌的發部位不影響其預後，然而原發腫瘤是否接受手術則會影響預後。

Purpose : To report the treatment outcome of the adenoid cystic carcinoma (ACC) of the respiratory tract. Materials and Methods : Twelve ACC patients diagnosed between 1987 and 2012 were retrospectively reviewed. Surgical resection and radiotherapy status were obtained from medical records. Overall survival (OS) and progression free survival (PFS) were analyzed using the Kaplan-Meier method. Results : There was no statistical difference in OS (p= 0.177) and PFS (p= 0.264) of the upper and lower airway ACCs. However, there was a significantly better OS (p= 0.005) and PFS (p= 0.016) in patients that received surgical excision. Conclusions : The primary site does not affect the prognosis of ACCs. Surgical intervention plays a critical role in the management of ACCs.
