Objective  To enhance the understanding of the primary salivary glandtype lung cancer (PSGLC) and improve the diagnostic rate of the disease. Methods  The clinical data of 41 patients with PSGLC pathologically confirmed in West China Hospital between October 2009 and October 2015 were analyzed in terms of clinical features, therapy and prognosis. Results  All the 41 patients (21 males and 20 females) accounted for 0.22% (41/18 738) of the primary malignant lung tumor diagnosed in the same period. The patients aged from 16 to 72 with the median age of 43.6. The disease course was 1 month to 6 years, and 12 had smoking history. There were 23 cases of adenoid cystic carcinoma, 15 of mucoepidermoid carcinoma and 3 of acinic cell carcinoma. The symptoms, chest-computed tomography and fiberbronchoscopy examination had no specificity. There were 34 patients who had undergone surgery, in whom 3 had fiberbronchoscopy, 4 had oral traditional Chinese medicine treatment, 5 had chemotherapy and radiotherapy at the same time, 9 received chemotherapy only, and 4 recived radiotherapy only. Follow-up period lasted for 2-65 months, with the median time of 38 months. Two patients had recrudescence, 6 patients had distant metastasis and 1 patient died. Conclusions  PSGLC have no specific clinical features; its diagnosis basically rely on pathological examination. After comprehensive treatment mainly on surgery, the prognosis of the disease is better than other malignant lung cancers.
