目的:探讨特异性泛素肽酶22(USP22)、C-myc和Caspase-3蛋白在食管鳞状细胞癌组织中的表达及临床意义。方法:采用免疫组化SP 法检测45例食管鳞状细胞癌组织、癌旁不典型增生组织及正常食管组织中USP22、C-myc和Caspase-3蛋白的表达,分析三者与食管鳞状细胞癌临床病理学特征的关系。结果:食管鳞状细胞癌、癌旁不典型增生和正常食管组织中USP22、C-myc、Caspase-3蛋白的阳性表达率比较差异具有统计学意义(χ2=39.614、41.838和33.889,P<0.001)。食管鳞状细胞癌组织中USP22、C-myc蛋白的表达与肿瘤浸润深度、淋巴结转移、分化程度及临床分期有关(P<0.05),Caspase-3蛋白的表达与肿瘤分化程度有关(P<0.05);USP22蛋白与C-myc蛋白表达呈正关联(rP=0.559, P<0.001),两者与 Caspase-3蛋白表达呈负关联(rP =-0.468和-0.477, P<0.001)。结论:USP22、C-myc高表达和Caspase-3低表达可能与食管癌发生发展相关。
目的:探討特異性汎素肽酶22(USP22)、C-myc和Caspase-3蛋白在食管鱗狀細胞癌組織中的錶達及臨床意義。方法:採用免疫組化SP 法檢測45例食管鱗狀細胞癌組織、癌徬不典型增生組織及正常食管組織中USP22、C-myc和Caspase-3蛋白的錶達,分析三者與食管鱗狀細胞癌臨床病理學特徵的關繫。結果:食管鱗狀細胞癌、癌徬不典型增生和正常食管組織中USP22、C-myc、Caspase-3蛋白的暘性錶達率比較差異具有統計學意義(χ2=39.614、41.838和33.889,P<0.001)。食管鱗狀細胞癌組織中USP22、C-myc蛋白的錶達與腫瘤浸潤深度、淋巴結轉移、分化程度及臨床分期有關(P<0.05),Caspase-3蛋白的錶達與腫瘤分化程度有關(P<0.05);USP22蛋白與C-myc蛋白錶達呈正關聯(rP=0.559, P<0.001),兩者與 Caspase-3蛋白錶達呈負關聯(rP =-0.468和-0.477, P<0.001)。結論:USP22、C-myc高錶達和Caspase-3低錶達可能與食管癌髮生髮展相關。

To investigate the expression and clinical significance of USP 22, C-myc and Caspase-3 proteins in e-sophageal squamous cell carcinoma (ESCC).Methods: SP method of immunohistochemical was used to examine the ex-pressions of USP22,C-myc and Caspase-3 proteins in 45 cases of ESCC,the atypical hyperplasia and normal esophageal tis-sues.Results:The positive expression rates of USP22,C-myc and Caspase-3proteins in 45 cases of ESCC were 60.00%, 66.67%,31.11%, respectively.There were significant differences between ESCC ,the atypical hyperplasia tissues and nor-mal esophageal mucosa (χ2 =39.614,41.838 and 33.889,P<0.001);There was relationship in the expression intensity of USP22 ,C-myc proteins and the differentiation grade of carcinoma , invasion,lymph node metastasis and clinical stages (P<0.05),The expressive intensity of Caspase-3 protein was related with the differentiation grade of carcinoma merely (P<0.05);The expression level of USP22 was positively correlated with that of C-myc(rP =0.559, P<0.001),both of them was negatively correlated with that of Caspase-3(rP =-0.468 and -0.477, P<0.001).Conclusion: The high level of USP22 and low level of C-myc might be necessary in the development and evolution of ESCC .
