特发性肺纤维化患者血清肿瘤标志物含量变化及其临床意义

目的 探讨特发性肺纤维化(IPF)患者血清多种肿瘤标志物含量的变化及其临床意义.方法 采用化学发光法检测25例IPF患者(IPF组)和23例正常对照者(对照组)外周血多种肿瘤标志物甲胎蛋白(AFP)、癌胚抗原(CEA)、CA125、CA153、CA199,同时检测患者血气、肺功能参数等临床指标.结果 IPF组与对照组外周血AFP[(2.41±0.95)μg/L与(1.29±1.13)μg/L,t=4.32,P＜0.05]、CEA[(7.12±2.68)μg/L与(2.14±0.57)μg/L,t=3.69,P＜0.05]、CA125[(118.52±31.24)kU/L与(23.97±8.47)kU/L,t=4.15,P＜0.05]、CA153[(47.58±14.57)kU/L与(9.24±4.21)kU/L,t=5.87,P＜0.05]、CA199[(165.78±21.13)kU/L与(14.51±5.74)kU/L,t=4.22,P＜0.05]均明显高于对照组,差异具有统计学意义.且血清AFP、CEA、CA125、CA153、CA199含量均与动脉血氧分压(r值为-0.15～-0.55,P＜0.05)、肺活量(r值为-0.09～-0.49,P＜0.05或P＜0.01)、肺弥散量(r值为-0.17～-0.61,P＜0.05)呈负相关.各肿瘤标志物与ESR和CRP无相关性(P均＞0.05).血清多种肿瘤标志物的进行性升高与肺纤维化程度的进展正相关.经激素治疗后,25例IPF患者血清AFP[(2.41±0.95)μg/L与(1.67±1.22)μg/L,t=5.41,P＜0.05]、CEA[(7.12±2.68)μg/L与(3.75±1.96)μg/L,t=4.63,P＜0.05]、CA125[(118.52±31.24)kU/L与(53.22±13.56)kU/L,t=3.97,P＜0.05]、CA153[(47.58±14.57)kU/L与(19.35±8.74)kU/L,t=5.15,P＜0.05]、CA199[(165.78±21.13)kU/L与(58.85±17.31)kU/L,t=6.34,P＜0.05]水平明显下降.结论 IPF患者血清多种肿瘤标志物含量增加,并与肺功能损害程度密切相关,可能提示肺纤维化的进展,是预后不良的标志.

Abstract：

Objective To investigate the clinical significance of multi-tumor biomarkers combined variation in patients with idiopathic pulmonary fibrosis(IPF).Methods Multiple serum tumor biomarkers,including AFP,CEA,CA125,CA153 and CA199 were detected in 25 patients with IPF and 23 healthy controls by chemiluminescence method,and the blood gas analysis,pulmonary function parameters and other clinical data were also collected simultaneously.Results All serum biomarkers measured in this study were significantly higher in IPF group than control,AFP([2.41±0.95]μg/L vs.[1.29±0.13]μg/L,t=4.32,P＜0.05),CEA([7.12±2.68]μg/L vs.[2.14±0.57]μg/L,t=3.69,P＜0.05),CA125([118.52±31.64]kU/L vs.[23.97±8.47]kU/L,t=4.15,P＜0.05),CA153([47.58±14.57]kU/L vs.[9.24±4.21]kU/L,t=5.87,P＜0.05),and CA199([165.78±21.13]kU/L vs.[14.51±5.74]kU/L,t=4.22,P＜0.05).The serum levels of AFP,CEA,CA125,CA153,CA199 were negatively correlated with blood oxygen pressure(r=-0.15--0.55,Ps＜0.05),vital capacity(r=-0.09--0.49,Ps＜0.05),lung diffusion capacity(r=-0.17--0.61,Ps＜0.05),while no significant correlations were found between different biomarker levels and ESR and CRP(Ps＞ 0.05).In addition,the serum level of different tumor markers increased along with the progress of pulmonary fibrosis,which showed statistical significance(Ps＜0.05).After hormone medication therapy,the serum tumor marker levels decreased significantly in IPF patients[AFP[2.41±0.95]μg/L vs.[1.67±1.22]μg/L,t=5.41,P＜0.05,CEA([7.12±2.68]μg/L vs.[3.75±1.96]μg/L,t=4.63,P＜0.05,CA125([118.52±31.64]kU/L vs.[53.22±13.56]kU/L,t=3.97,P＜0.05),CA153(47.58±14.5 vs.19.35±8.74 kU/L,t=5.15,P＜0.05),CA199(165.78±21.13 vs.58.85±17.31 kU/L,t=6.34,P＜0.05)].Conclusion Multiple serum tumor biomarkers significantly increased in patients with IPF,and had a close correlation with lung function damage.The changes of these biomarkers indicated the progress of pulmonary fibrosis,which served as the predictors of poor prognosis.
