ABSTRACT

Objective To examine the expression of Cath D,SP-A and GLUT-1 in patients with bronchiogenic carcinoma.Methods A total of 41 patients were included in the study,10 of whom received the histological diagnosis of small cell lung cancer(SCLC).The other 28 were squamous cell carcinoma(SC) and 3 were inflammation.And all the samples were taken from the patients′ tunica mucosa bronchiorum through bronchofibroscope,then we detected the cathepsin D,SP-A and GLUT-1 following SP immunohistochemistry.Results ①Cath D 6 samples(60%) in group SCLC were negtive expression(-6),4(40%)were moderately positive(++4),4(14%) were negative(-4),2(7%) were positive(+2),8(28%) were moderately positive(++8) and 14(50%) were intensive positive(+++14) in the other group.SCLC was significant different from SC in expressing cathepsin D(P
