摘 要:目的通过临床病例研究,测定半脘氨酰白三烯受体1(CysLTlR)在肝癌组织中的表达及其与临床病理特征之间的关系。方法收集肝癌及癌旁肝组织标本各30例及12例肝血管瘤患者标本为正常对照。采用实时荧光定量PCR、免疫组织化学方法,分别从mRNA水平及蛋白水平检测肝组织中CysLTlR的表达量,以及其与肝癌临床病理参数的关系。采用SPSS17.0进行统计学处理,两组间比较用t检验和Fisher确切概率法,生存分析用Kaplan-Meier法,检验水准尸〈0.05为差异有统计学院意义。结果CysLT1R mRNA相对表达量在癌旁组织为0.0339±0.0221高于正常肝组织的0.0154±0.0123(t=-2.310,P=0.033)和肝癌组织的0.0127±0.0116,(t=2.911,JD=0.008),差异均有统计学意义;而在癌组织和正常肝组织中差异无统计学意义(P〉0.05),CysLT1R mRNA在癌旁组织中的表达在不同肿瘤分期中有显著差异Q=3.438,P=0.008),在HBV感染组与非感染组之间也存在统计学差异(t=3.59,P=0.006)。CysLT1R蛋白在癌旁组织的阳性表达率为100%大于正常肝组织的41.67%(P=0.000)和肝癌组织的43.33% (P=0.000),受体的表达与肿瘤分期有关(P=0.042)。在肝癌组织中CysLT1R mRNA在不同表达水平组生存期差异有统计学意义(t=4.372,P〈0.05)。此外患者的生存时间受肿瘤的临床分期和甲胎蛋白水平影响(f值分别为24.187和8.75,P值均〈0.05)。结论CysLT1R在癌旁组织中表达量明显增高,且在肝组织中表达量与肿瘤临床分期及预后有关,提示CysLT1R可能参与肝癌的发生和发展过程。Objective To investigate expression of the cysteinyl leukotriene receptor (CysLT1R) in hepatocellular carcinoma (HCC) tissues and determine its clinical significance. Methods Cancerous and paraneoplastic liver tissues were collected from 30 patients with HCC and from 12 patients with liver hemangioma patients (controls). Real-time PCR and immunohistochemistry were used to evaluate the expression of CysLT1R in these tissues and assess the relationship with clinical pathological features. T-test, Fisher's exact test and Kaplan-Meier survival analysis were used for statistical analysis. Results The expression of CysLT1R in adjacent liver tissues (100%) was higher than that in the HCC (43.33%, P = 0.000) and normal liver tissues (41.67%,P = 0.000). The level ofCysLT1R mRNA was also higher in paraneoplastic liver tissues (0.0339±0.0221) than in the paired HCC tissues (0.0127±0.0116, t = 2.911, P = 0.008) and normal liver tissues (0.0154±0.0123, t = -2.310, P = 0.033). There was no difference between the levels in HCC and normal liver tissues (P 〉 0.05). Higher level of CysLT1R mRNA, higher level of serum alpha-fetoprotein, and higher tumor stage (III-IV) were associated with poor prognosis (respectively 4.372,P = 0.037; 24.187,P = 0.000; 8.75,P = 0.003). However, no evident relationship between the expression of CysLT1R and other clinical features was observed. Conclusions Overexpression of CysLT1R may contribute to the occurrence and progression of HCC.
