Abstract:
Objective To explore the diagnosis rate.pathology types and positive rate of cancer cell in spu-tum of early central pulmonary carcinoma in three obstructive signs on chest X ray screened by fiberbromchoscope.Methods 326 cases of three obstructive signs with high risk of lung cancer were screened for central pulmonarycarcinoma by spiral CT.biopsy by fiberbronchoscope and cytological examination of sputum.Results 32 patients were diagnosed with central pulmonary carcinoma,with morbidity of 9.8%.In these patients,21 were confirmed with obstructive pneumonia(65.6%),7 with obstructive atelectasis(21.9%),4 with obstructive emphysema(12.5%);In terms of pathology type,16 cases were defined as squamous cell carcinoma(50.0%),9 as small cell carcinoma(28.1%).3 were as large cell carcinoma(9.4%).2 were as adenocarcinoma(6.3%),1 as admosquamous carci-noma(3.1%),1 as bronchial gland carcinoma(3.1%);cancer cell could be found in sputum of 5 patients of 32 cases,among them,it was found in 3 of 21 patients with obstructive pneumonia(14.3%),1 in 7 patients with ob-structive atelectasis(14.3%),1 in 4 patients with obstructive emphysema(25.0%).Conclusion The prevelance of early central pulmonary carcinoma in three obstructive signs on chest X-ray is 9.815%,in which squamous carci-noma and small-cell carcinoma are common in pathology type.Screening can increase the detection rate of early pul-monary carcinoma.
