摘要: 目的 探究半胱氨酸蛋白酶抑制剂S(CST4)在哈萨克族食管鳞状细胞癌(ESCC)中的表达情况及临床意义。方法 收集2010年至2020年于新疆医科大学第一附属医院49例接受手术治疗的哈萨克族食管鳞状细胞癌患者的新鲜组织标本及石蜡包埋的组织标本。用RT-qPCR及免疫组化法检测食管癌组织与对应癌旁组织中CST4的表达。用χ2检验分析CST4表达与患者临床病理资料之间的关系。用单因素及多因素分析CST4表达与患者术后生存期的关系。结果 CST4 mRNA在食管癌组织中的表达量明显高于对应癌旁组织(P<0.05)。CST4蛋白在食管癌组织中的表达率(53.1%, 26/49)明显高于对应癌旁组织(28.2%, 11/39)(χ2=5.506,P<0.05)。CST4表达与淋巴结转移(P<0.05)和TNM分期(P<0.01)有关,CST4高表达者淋巴结转移率更高,肿瘤TNM分期更晚。单因素生存分析发现,CST4表达水平(P<0.01)、肿瘤浸润深度(P<0.05)和TNM分期(P<0.01)均与患者生存率相关。进一步行多因素生存分析发现,CST4表达水平(P<0.05)、肿瘤浸润深度(P<0.05)是影响哈萨克族食管鳞状细胞癌患者预后的独立危险因素。结论 CST4基因的表达可能与哈萨克族食管鳞癌的发生、进展及预后有关。CST4的表达可作为食管鳞癌患者病情及预后评估的指标。

Abstract: Objective To explore the expression and clinical significance of cystatin S(CST4) in patients with esophageal squamous cell carcinoma(ESCC)in Kazakhs. Methods Totally 49 specimens from Kazakh ESCC patients who received surgical treatment were collected. RT-qPCR and immunohistochemical methods were used to detect CST4 expression in cancer tissues and adjacent tissues. Chi-square(χ2) test was used to analyze the relationshipbetween CST4 expression and the clinicopathological parameters. Kaplan-Meier method and Cox regression model were used to estimate the correlation between CST4 expression and overall survival. Results CST4 mRNA expression in ESCC tissues was higher than that in adjacent tissues (P<0.05). CST4 protein expression in ESCC tissues (53.1%, 26/49) was higher than that in adjacent tissues (28.2%, 11/39) (χ2=5.506, P<0.05). The expression of CST4 was significantly associated with lymph node metastasis (P<0.05) and TNM stage (P<0.01). Those with high CST4 expression had higher lymph node metastasis rate and later TNM stage. Univariate survival analysis showed that CST4 expression level(P<0.01), invasion depth (P<0.05) and TNM stage (P<0.01) were associated with overall survival. Multivariate survival analysis showed that the CST4 expression (P<0.05) and the invasion depth (P<0.05) were independent prognostic factors for survival of ESCC patients. Conclusions CST4 expression is related to the occurrence, progression and prognosis of ESCC so it can be a potential prognostic marker for ESCC in Kazakhs.
