摘要
目的:研究肝细胞癌(hepatic cell carcinoma,HCC)组织中细胞分裂周期蛋白25同源蛋白C(cell division cyclin 25 homolog C,CDC25C)与紧密连接蛋白Claudin-6(CLDN6)的表达情况,探讨其与HCC的发生、发展、预后的关系。方法:应用免疫组织化学SABC法检测58例HCC、24例癌旁组织和18例正常肝脏组织中CDC25C和CLDN6的表达情况,并分析两者与临床病理特征和术后无瘤生存期的关系。结果:CDC25C在HCC组织、癌旁组织、正常肝脏组织表达阳性率分别为86.2%、45.8%、11.1%,表达差异均有统计学意义(P<0.05)。CDC25C在HCC组织中的表达与乙型肝炎表面抗原(HBsAg)、肿瘤直径大小和肿瘤分化程度有关(P<0.05)。CLDN6在HCC组织、癌旁组织、正常肝脏组织表达阳性率分别为77.6%、41.7%、16.7%,表达差异均有统计学意义(P<0.05)。CLDN6在HCC组织中的表达与肿瘤直径大小有关(P<0.05)。HCC中CDC25C阳性组及CDC25C阴性组的中位无瘤生存时间分别为12个月和15个月,差异有统计学意义(P<0.05)。CLDN6阳性组及CLDN6阴性组中位无瘤生存时间分别为12个月和14个月,差异有统计学意义(P<0.05)。结论:CDC25C和CLDN6可能在肝细胞癌的发生、发展及复发过程中起重要作用,有望成为肝癌诊断及预测预后的重要指标。
Objective: To study the expression of cell division cyclin 25 homolog C (CDC25C) and Claudin-6(CLDN6) proteins in hepatic cell carcinoma(HCC) and discuss its clinical significance with the occurrence, development and prognosis of HCC. Methods: Immunohistochemical SABC method was performed to detect the expression of CDC25C and CLDN6 proteins in 58 cases of HCC tissues, 24 cases of tumor-adjacent tissues and 18 cases of normal liver tissues. The relationship between clinical pathological characteristics and postoperative disease-free survival time was ana- lyzed. Results: The expression positive rates of CDC25C in HCC tissues, tumor-adjacent tissues and normal liver tissues were 86.2% , 45.8% , 11.1%. The differences were statistically signifi- eant(P 〈0.05). The expression of CDC25C in HCC tissues was closely related to HBsAg, tumor size and tumor differentiation degree(P 〈 0.05). The positive expression rates of CLDN6 in HCC tissues, tumor-adjacent tissues and normal liver tissues were 77.6% , 41.7% , 16.7% , the differ- ences were statistically significant (P 〈 0.05 ). The expression of CLDN6 in HCC tissues was closely related to tumor differentiation degree (P 〈 0.05 ). The median disease-free survival time of CDC25C positive and negative groups was 12 months and 15 months respectively, the differences were statistically significant(P 〈 0.05). The median disease-free survival time of CLDN6 positive and negative groups were 12 months and 14 months respectively. The differences were statistically significant(P 〈 0.05). Conclusion: CDC25C and CLDN6 may play important roles in the proces- ses of the occurrence, development and recurrence of HCC. They are expected to be the important indicators for diagnosis and prognosis of HCC.
