The detection of serum soluble B7-H4 levels in non-small cell lung cancer patients and its significance / 中华检验医学杂志

ABSTRACT

ObjectiveTo detect serum soluble B7-H4 (sB7-H4) levels in patients with non-small cell lung cancer ( NSCLC ) and explore its clinical significances.MethodsThe sB7-H4 levels the sera of in 102 NSCLC patients,60 benign lung disease patients and 90 healthy controls were determined by ELISA.The relation between serum sB7-H4 levels and NSCLC of pathological staging was analyzed by use of t test.ResultsThe serum sB7-H4 levels in NSCLC,benign lung disease and heathy control groups were (45.61 ±5.67 ),( 30.14 ± 3.51 ) and ( 28.52 ± 4.76 ) μg/L,respectively.The levels of NSCLC group were significantly higher than those of benign lung disease and healthy control groups ( t =2,59 and 3.61,P ＜ 0.05 ).The serum sB7-H4 levels of Ⅲ/IV stage NSCLC patients ( 63.93 t 4.76 ) μgL,with lymph node metastasis (61.73 ±3.97) μg/L and before operation patients (63.29 ±6.19) μg/L were relatively higher thanthose inthe Ⅰ/Ⅱ stage(35.12 ± 3.88 )μg/L, without lymphnode metastasis (40.26 ± 5.39 ) μg/L,after operation ( 40.51± 4.08 ) μg/L.There were significant difference ( t =6.78,5.73 and 3.67,P ＜ 0.05 ).Conclusions Serum sB7-H4 of NSCLC patients increases significantly and correlates with clinical stages and therapeutic conditions.Detecting on sB7-H4 is helpful for lung cancer diagnosis and therapeutic effect evaluation.
