CTGF、PCNP在胰腺癌中表达意义的探讨

目的：探讨结缔组织生长因子（CTGF）、PCNP在胰腺癌组织中的表达水平及意义。方法采用免疫组织化学法与蛋白质免疫印迹法检测39例胰腺癌及癌旁组织中CTGF和PCNP的表达情况，分析其与临床病理因素的关系。结果 CTGF、PCNP在胰腺癌中的阳性表达率均显著高于癌旁组织和正常胰腺组织，差异有统计学意义（χ2＝60．41、51．46，均 P＜0．01）；CT‐GF、PCNP的阳性表达率分别与TNM分期、淋巴结转移明显相关（P＜0．05）。结论 CTGF、PCNP在胰腺癌组织中表达明显上升，且两者的表达水平与肿瘤的分期、淋巴结转移状况有着明显的相关性。

The study for the expression of CTGF,PCNP and their significance in pancreatic cancer

Objective To study the expression of connective tissue growth factor(CTGF) and PEST containing nuclear pro‐tein(PCNP) and their significance in pancreatic cancer .Methods The expressions of CTGF and PCNP proteins were tested by im‐munohistochemistry and Immunofluorescence in 39 cases of pancreatic carcinomas and adjacent paracancerous tissues .Results The positive rate of CTGF and PCNP in pancreatic carcinomas was significantly higher than adjacent paracancerous tissues(χ2 =60 .41 , 51 .46 ,all P<0 .01) .The differences of the expression of CTGF and PCNP in pancreatic carcinoma of tumor differentiation ,TNM stage and lymph node metastasis was significant (P< 0 .05) .Conclusion The expression of CTGF and PCNP in the pancreatic cancer was obviously increased ,and the level of CTGF ,PCNP had remarkable connection with the stages of tumor and the condition of lymph node metastasis .
