摘　　要：目的:探讨泛素特异性蛋白酶20(ubiquitin specific protease 20,USP20)在口腔鳞癌(oral squamous cell carcinoma,OSCC)中的表达及与临床病理指标的关系。方法:筛选癌症基因组图谱(the cancer genome atlas,TCGA)数据库中OSCC样本及配对癌旁样本,分别进行差异表达分析和配对差异分析。通过免疫组织化学SABC法检测组织芯片OSCC及癌旁和正常组织中USP20的表达水平,分析其与临床病理指标间的相关性。采用GraphPad Prism 9.5.0软件对数据进行统计学分析。结果:TCGA数据显示,USP20在OSCC中的表达显著高于癌旁组织(P<0.001)。免疫组织化学染色评分显示,USP20在OSCC中的表达显著高于癌旁组织和正常组织(P<0.01);组织芯片临床病理指标分析显示,USP20的染色评分在肿瘤不同分化程度(P<0.05)及原发灶大小(P<0.01)的差异具有统计学意义。Kaplan-Meier分析显示,高表达组与低表达组总体生存时间及5年生存率相比无统计学差异(P>0.05)。结论:USP20可能参与OSCC的发生与进展,与肿瘤分化存在相关性,可加速其生长。PURPOSE:To investigate the expression of ubiquitin specific protease 20(USP20)in oral squamous cell carcinoma(OSCC)and its correlation with clinicopathological parameters.METHODS:OSCC samples and paired paracancerous samples were screened from the TCGA database for differential expression analysis and paired differential analysis.Immunohistochemical staining was used to detect the expression level of USP20 in OSCC tissue,paracancerous tissues and normal tissues.The correlation between USP20 expression level and clinicopathological parameters of tissue microarray was analyzed.GraphPad Prism 9.5.0 software was used for statistical analysis of the data.RESULTS:TCGA data showed that the expression of USP20 in OSCC was significantly higher than that in paracancerous tissue(P<0.001).Immunohistochemical staining score showed that the expression of USP20 in OSCC was significantly higher than that in paracancerous tissues and normal tissues(P<0.01).The analysis of clinicopathological indicators of tissue microarray showed that the staining scores of USP20 were significantly different in tumor differentiation(P<0.05)and primary tumor size(P<0.01).Kaplan-Meier survival analysis indicated no significant difference in overall survival time and 5-year survival rate between high expression group and low expression group(P>0.05).CONCLUSIONS:USP20 is highly expressed in OSCC compared with paracancerous tissues and normal oral tissues.The expression of USP20 is associated with differentiation and the size of primary tumor in OSCC,and can accelerate its growth.
