解整合素-金属蛋白酶8对非小细胞肺癌的诊断价值

目的 探讨解整合素-金属蛋白酶8(ADAM8)对非小细胞肺癌患者(NSCLC)的诊断价值.方法 应用ELISA方法 检测62例NSCLC患者、27例良性肺病患者和32例健康体检者血清中的ADAM8蛋白表达水平.结果 NSCLC组血清ADAM8水平(456.88±143.87)ng/L]高于良性肺病组(271.63±74.20)ng/L]和正常对照组(253.09±72.15)ng/L],差异均有统计学意义(P均<0.01),良性肺病组AD-AM8表达水平比正常对照组略高,但差异无统计学意义(P0.05);ADAM8在腺癌患者中表达水平与鳞癌相比差异无统计学意义(462.54±161.387)ng/L与(449.04±118.03)ng/L,P0.05],Ⅲ、Ⅳ期NSCLC患者血清中ADAM8的水平(498.80±151.80)ng/L]高于Ⅰ、Ⅱ期患者(385.80±95.85)ng/L],差异有统计学意义(P<0.01);检测ADAM8对NSCLC的诊断敏感性为77.4%,特异性为90.6%.结论 ADAM8在NSCLC患者血清中过度表达,表明其与肺癌的发生和转移有着密切的关系,检测ADAM8对NSCLC的诊断有一定的辅助价值.

Diagnostic value of a distintegrin and metalloproteases-8 in non-small cell lung cancer

Objective To study the diagnostic values of a distintegrin and metalloproteases-8 (ADAMS) in non-small cell lung cancer(NSCLC).Methods The serum protein level of ADAM8 was assayed by ELISA in 62 NSCLC patients,27 lung benign lesions and 32 healthy people.Results The serum levels of ADAM8 of NSCLC (456.88±143.87)ng/L] were higher than those with lung benign lesions (271.63±74.20) ng/L] and normal controls(253.09±72.15 ng/L) (P<0.01), but there was no significant difference between lung benign lesions and normal controls (P0.05).No significant difference was found between adenocarcinoma and squamous cell carcinoma in serum ADAM8 level,the serum levels of ADAM8 in NSCLC with stages Ⅲ-Ⅳ (498.80 ± 151.80) ng/L] were higher than those with stages Ⅰ -Ⅱ(385.80±95.85) ng/L] (P <0.01 ).The diagnostic sensitivity of detection of ADAM8 for NSCLC was 77.4% and the specificity was 90.6%.Conclusion The overexpression of ADAM8 in serum of NSCLC patients indicates that ADAM8 is related with occurrence and metastasis of NSCLC;De-tection of ADAM8 could assist the diagnosis for NSCLC.
