摘要:
目的 检测降钙素基因相关肽受体成分蛋白(CRCP)在肝细胞癌及癌旁组织中的表达水平,探究其与肝细胞癌临床病理和患者预后的相关性。 方法 收集2003年6月—2009年9月在海军军医大学附属东方肝胆外科医院行手术切除治疗的79例肝细胞癌患者的肝癌组织及相应癌旁组织标本,制作组织芯片,免疫组化定量分析,提取蛋白进行Western Blot检测,比较CRCP在肝癌组织与癌旁组织中的表达差异。计数资料组间比较采用χ2检验,采用受试者工作特性曲线(ROC曲线)分析获得曲线下面积(AUC),评估拟合优度,并使用Youden指数确定最佳截断值,利用Kaplan-Meier生存分析法分析CRCP表达与肝细胞癌预后的关系,两组间比较采用log-rank检验。 结果 79例肝细胞癌患者中,男67例,女12例,年龄10~72岁;病理分级4级1例,3级61例,2级17例;20例合并门静脉癌栓;巴塞罗那分期0期5例,A期55例,B期11例,C期8例。免疫组化结果显示,75.9%的患者肝癌组织中CRCP表达水平明显低于癌旁组织。CRCP低表达肝细胞癌患者的CK19阳性、肿瘤包膜不完整、合并门静脉癌栓和肿瘤病理分级高的患者所占比例更高(χ2值分别为6.410、4.829、9.319、9.083,P值均<0.05)。与CRCP低表达组相比,CRCP高表达组患者的总体生存期更长,复发率更低(P值分别为<0.001、0.009)。另取6例患者的癌组织与癌旁组织进行Western blot检测,结果显示,4例患者肝癌组织中CRCP表达水平低于癌旁组织。 结论 肝癌组织中CRCP低表达相较于高表达患者预后更差,CRCP可能参与肝细胞癌的发生发展与转移过程,提示该分子或可作为肝细胞癌患者预后判定的生物标志物。 -

Abstract:Objective To investigate the expression level of calcitonin gene-related peptide-receptor component protein (CRCP) in hepatocellular carcinoma (HCC) tissue and adjacent tissue and its association with the clinicopathological features and prognosis of patients. Methods HCC and adjacent tissue samples were collected from 79 HCC patients who underwent surgical resection in Eastern Hepatobiliary Surgery Hospital, Navy Medical University, from June 2003 to September 2009. Tissue microarray was prepared, and immunohistochemistry was used for quantitative analysis. Related proteins were extracted and measured by Western blot, and the expression of CRCP was compared between HCC tissue and adjacent tissue. The chi-square test was used for comparison of categorical data between groups. The receiver operating characteristic (ROC) curve analysis was performed to obtain the area under the ROC curve (AUC), and goodness of fit was evaluated. Youden index was used to determine the optimal cut-off value. and the Kaplan-Meier survival analysis was used to analyze the association of CRCP expression with the recurrence and prognosis of HCC, and the log rank test was used for comparison between the two groups. Results Among the 79 HCC patients, there were 67 male patients and 12 female patients, with an age of 10-72 years, and 20 patients had portal vein tumor thrombus. As for pathological grade, 1 had grade 4 HCC, 61 had grade 3 HCC, and 17 had grade 2 HCC; as for BCLC stage, 5 had BCLC stage 0 HCC, 55 had BCLC stage A HCC, 11 had BCLC stage B HCC, and 8 had BCLC stage C HCC. Western blot showed that the expression level of CRCP in HCC tissue was lower than that in adjacent tissue in 4 patients, and immunohistochemistry showed that the expression level of CRCP in HCC tissue was significantly lower than that in adjacent tissue in 75.9% of the patients. Low CRCP expression was associated with CK19 positivity, incomplete tumor capsule, presence of portal vein tumor thrombus, and high pathological grade (χ2=6.410, 4.829, 9.319, and 9.083, all P < 0.05). Compared with the low CRCP expression group, the high CRCP expression group had a significantly longer overall survival time and a significantly lower recurrence rate (P < 0.001 and P=0.009). Conclusion Patients with low CRCP expression in HCC tissue tend to have a poorer prognosis than those with high CRCP expression, and CRCP may participate in the development, progression, and metastasis of HCC, suggesting that this molecule can be used as a potential biomarker to predict the prognosis of HCC patients. -

注:a,2例肝癌患者癌组织及癌旁组织中的CRCP表达情况(×12.8),CRCP在胞浆与胞核中均有表达,与癌组织相比,癌旁组织染色更深,提示癌旁组织中CRCP表达量更高。b,79例肝癌患者CRCP的相对表达,每位患者癌组织与癌旁组织的免疫组化评分(Positivity,简称P)相除后取log值[即log(P癌组织/P癌旁组织)]并作图,其中60例(75.9%)患者的癌组织CRCP表达量低于癌旁组织即为低表达部分,19例(24.1%)癌组织CRCP表达量高于癌旁组织即为高表达部分。
