摘要(Abstract):

目的:探讨程序性死亡因子4(PDCD4)、5(PDCD5)及髓样细胞白血病-1(MCL-1)在结直肠癌(CRC)中表达及意义。方法:应用免疫组化检测PDCD4、PDCD5与MCL-1在CRC(50例)、结直肠腺瘤(20例)和结直肠黏膜慢性炎症(20例)中的表达,同时分析PDCD4、PDCD5及MCL-1蛋白的表达与CRC患者淋巴结转移、生存期及TNM分期的关系,采用spearman's方法分析结直肠组织中MCL-1、PDCD4及PDCD5蛋白表达的相关性。结果:PDCD4、PDCD5及MCL-1在CRC、结直肠腺瘤、结直肠黏膜慢性炎症中的阳性表达率分别比较,差异有统计学意义(P<0.05);CRC患者标本中,MCL-1与PDCD4(r=-0.401,P<0.05)、PDCD5(r=-0.445,P<0.05)表达呈负相关,而PDCD4与PDCD5的表达呈正相关(r=0.510,P<0.05);PDCD4及MCL-1在CRC组织中的表达与TNM分期、淋巴结转移及5年生存期有关(P<0.05)。结论:CRC发生及发展与PDCD4、PDCD5及MCL-1的蛋白表达有关。
Objective: To explore the expression and clinical significance of PDCD4,PDCD5 and MCL-1 in colorectal cancer( CRC). Methods: The immunohistochemistry was adopted to detect protein levels of PDCD4,PDCD5 and MCL-1 in 50 cases of colorectal cancer,20 cases of colorectal adenoma and 20 cases of colorectal inflammation. At the same time,the correlation between the expression of PDCD4,PDCD5 and MCL-1 and lymph node metastasis,survival length and TNM staging in patients with colorectal carcinoma was analyzed,and Spearman 's method was adopted to analyze the correlation between expression of PDCD4,PDCD5 and MCL-1. Results: There were statistically significant differences in PDCD4,PDCD5 and MCL-1 positive expression rate in the CRC,colorectal adenoma and colorectal inflammation( P < 0. 05). In CRC patient specimens,MCL-1expresion was negatively correlated with PDCD4 expression( r =- 0. 401,P < 0. 05) and PDCD5( r =- 0. 445,P <0. 05) while PDCD4 expression was positively correlated with PDCD5 expression( r = 0. 510,P <0. 05). PDCD4 and MCL-1 expressions in CRC tissues were associated with TNM staging,lymph node metastasis and 5 years survival( P < 0. 05). Conclusion: The occurrence and development of CRC is correlated with the expression of PDCD4,PDCD5 and MCL-1.
