摘　　要：目的探讨肺癌相关抗原(lung tumor antigen LTA)在纤维支气管镜支气管肺泡灌洗液、胸水和血清中的检测结果对肺癌的临床诊断意义。方法收集72例非小细胞肺癌(non-small cell lung cancer NSCLC)伴胸腔积液患者和对照组68例肺部良性病变(benign lung disease BLD)患者的支气管肺泡灌洗液、胸水及血清样本,运用LTA检测试剂用快速乳胶凝集法分别检测,并对所得数据进行统计分析。结果肿瘤组病人支气管肺泡灌洗液、胸水和血清的LTA检测阳性率分别为58%、67%和75%,对照组三者的阳性检出率分别为22%、17%和20%,两组比较均有明显差异(P<0.05)。LTA阳性检出率以肿瘤组的血清样本最高,达75%。特异性以胸水样本最高,为82%。结论支气管肺泡灌洗液、胸水和血清LTA检测对肺癌的诊断有一定的临床参考意义。Objective To explore the clinical diagnostic value of LTA in lung eanaer Methods Patients were divided into two groups： non-small cell lung cancer（n = 72） ; bengln lung disease （n = 68 ）. The LTA levels in BLAF,pleural effusion f; luid and serum were detected by latex agglutination method. Results The NSCLC group：positive rate for LTA in BLAF ,pleural effusion and serum were 58% ,67% ,75%. While 22% ,17% ,20% in the control group. The difference between the two groups is significant（ P 〈 0.05 ）. Posi- tive rate of LTA in serum of the NSCLC group was the highest ,75%. The peculiarty for LTA in pleural effusion at the NSCLC group was the highest, 82%. Conclusion These results suggested that detection of LTA in BLAF,pleural effusion and serum is a valuable method for the diagnosis of lung cancer.
