【摘要】 目的探讨Fas和FasL mRNA在非小细胞肺癌(NSCLC)组织中的表达及临床意义。方法采用实时荧光定量RT-PCR法检测Fas和FasL mRNA在NSCLC及正常肺组织中的表达。结果在NSCLC组织中，鳞癌与腺癌肺组织中Fas mRNA(t=1.9773，P=0.0540)及FasL mRNA(t=1.5797，P=0.1210)的表达量无明显差别(P＞0.05)；在NSCLC组织中，Fas mRNA表达显著低于正常肺组织(t′=-5.6634，P＜0.05)，并与NSCLC的病理分级(F=3.81，P=0.0296)、临床分期(F=5.43，P=0.0029)及淋巴结转移(t=2.6621，P=0.0107)有关(P＜0.05)；FasL mRNA表达显著高于正常肺组织(t′=4.8258，P＜0.05)，并与NSCLC的病理分级(F=33.31，P=0.0000)、临床分期(F=9.82，P=0.0000)及淋巴结转移(t′=3.6015，t′(0.0500)=2.0627)有关(P＜0.05)。分期越早，分化越高，无淋巴结转移时，Fas mRNA表达越高，FasL mRNA表达量越低；分期越晚，分化越低，有淋巴结转移时，Fas mRNA表达越低，FasL mRNA表达越高。Fas和FasL mRNA表达之间无相关性(rs=0.2129，P＞0.05)。结论Fas和FasL mRNA表达与肺癌发生、发展、侵袭、转移及恶性程度密切相关，对判断肺癌恶性程度及治疗预后有重要参考价值。更多还原

【Abstract】 Objective To study the quantitative expression and clinicalsignificance of Fas and FasL mRNA in non-small cell lung cancer(NSCLC).Methods Real-time fluorescent quantitative RT-PCR method Was applied toinvestigate the quantitative expression of Fas and FasL mRNA in NSCLC andnormal lung tissue. Results In NSCLC, The levels of Fas mRNA(t=1.9773, P=0.0540) and FasL mRNA (t=1.5797, P=0.1210) were of no differencebetween squamous carcinoma and adencarcinoma (P＞0.05).The levels of Fas mRNAexpression in NSCLC were significantly lower than those in normal tissues(t’=-5.6634, P＜0.05), and positive expression of Fas mRNA was correlatedwith pathological grades(F=3.81, P=0.0296)、clinical stages(F=5.43,P=0.0029)and lymphatic metastasis(t=2.6621, P=0.0107), (P＜0.05);The levelsof FasL mRNA expression in NSCLC were singnificantly higher than those innormal tissues (t’=4.8258, P＜0.05), and positive expression of FasL mRNAwas correlated with pathological grades(F=33.31, P=0.0000)、clinicalstages(F=9.82, P=0.0000)and lymphatic metastasis(t’=3.6015, t’(0.0500)=2.0627), (P＜0.05); The positive expression levels of Fas mRNA inNSCLC showed negative correlation with that of differentiation and positivecorrelation with that of lymph node metastasis and clinical stages; And thepositive expression levels of FasL mRNA in NSCLC showed positive correlationwith that of differentiation and positive correlation with that of lymph nodemetastasis and clinical stages. There was no correlation in the expressionsbetween Fas and FasL mRNA (rs=0.2129, P＞0.05). Conclusions Abnormalexpression of Fas and FasL mRNA act correlatively to the originality,development、infiltration、metastasis and malignancy, The expression ofFas and FasL mRNA presents singnificance in evaluation of the malignancy andits theraputic prognosis of NSCLC.更多还原
