Clinical experience of 50 cases of adenoid cystic carcinoma of trachea and bronchi

Objective To study the part of clinical characteristics of trachea or bronchi adenoid cystic carcinoma and clinical value of the bronchoscopy cavity interventional therapy about it. Methods This study summarized total 50 patients of tracheal or bronchus adenoid cystic carcinoma who are diagnosed, treated and carefully followed in Tangdu hospital, The Fourth Military Medical University from January 2010 to July 2018.They were divided into bronchoscope intervention group (24 cases) and operation group (26 cases) And a retrospective analysis was then performed with their part of clinical characteristics and the comparison of therapeutic effect between the bronchoscopy cavity interventional therapy and the surgery. Results There were 30 females and 20 males and the median age was 49.62 years old.The main symptoms of all 50 cases were cough, expectoration and shortness of breath and some of them also accompany with hemoptysis and chest pain.Among 50 cases, 23 cases of carcinoma occurred in middle-to-lower bronchial segments, which is the largest part of all cases.8 cases scored grade Ⅰ at Borg index, 18 cases scored grade Ⅱ, 11 cases scored grade Ⅲ, and 13 cases scored grade Ⅳ.26 patients accepted surgery for the first time, and the other 24 patients accepted more than two kinds of bronchoscopy cavity interventional therapy for the first time.And the trachea or bronchi stenosis remission rate between two groups had no statistically difference (χ2=6.019, P=0.111). The Borg index after the bronchoscopy cavity interventional therapy (Z=-4.622, P<0.001) and the surgery (Z=-5.553, P<0.001) were both improved, and the difference was statistically significant.There was one case accepted the bronchoscopy cavity interventional therapy had a bad hemorrhage during the therapy. Conclusions Shortness of breath, unoperated patients with symptoms of bronchoscopy intervention can reduce the shortness of breath index, relieve shortness of breath, and the degree of stenosis of the humen is high.It is worthy of chlinical promotion.
