摘要: 目的 探讨脯氨酸-谷氨酸-亮氨酸富集蛋白1(Proline,glutamate and leucine rich protein 1,PELP1)表达与胃癌演进及预后的关系及意义。方法 采用免疫组化检测39例正常胃组织、48例低级别不典型增生胃组织、28例高级别不典型增生胃组织、77例胃癌组织中PELP1蛋白表达水平,观察胃癌不同演进阶段PELP1表达变化;分析胃癌患者PELP1表达水平与临床病理参数关系;通过在线癌症生存分析工具Kaplan-Meier Plotter分析胃癌PELP1表达与患者总生存期、首次进展前生存期和进展后生存期之间的关系。结果 胃癌演进过程中,PELP1表达水平逐渐升高,差异具有统计学意义(P<0.05);胃癌组织中PELP1表达与淋巴结转移、低肿瘤分化、高临床分期有关(P<0.05);PELP1高表达组患者总生存期、首次进展前生存期和进展后生存期均显著低于PELP1低表达组患者(P<0.05)。结论 高表达PELP1参与胃癌演进并且提示患者预后不良。

Abstract: Objective The aim of this study was to investigate the relationship and significance of proline,glutamate and leucine rich protein 1(PELP1)in the progression and prognosis of gastric cancer.Methods Immunohistochemistry was used to detect the expression of PELP1 protein in 39 normal gastric tissues,48 low-grade atypical hyperplasia gastric tissues,28 high-grade atypical hyperplasia gastric tissues,and 77 gastric cancer tissues.The expression of PELP1 in different stages of gastric cancer was observed.The correlation between the level of PELP1 and clinicopathological parameters of gastric cancer was analyzed.Kaplan-Meier Plotter,an online cancer survival analysis tool,was used to analyze the relationship between PELP1 expression in gastric cancer and overall survival(OS),survival before first progression(FP)and post progression survival(PPS).Results The level of PELP1 increased gradually during the progression of gastric cancer,and the differences were significant(P< 0.05);The expression of PELP1 in gastric cancer was significantly correlated with lymph node metastasis,low tumor differentiation and high clinical stage(P< 0.05);The OS,FP and PPS of patients with high level of PELP1 were significantly shorter than those with low level of PELP1(P < 0.05).Conclusion The high expression of PELP1 is involved in the progression of gastric cancer and suggests a poor prognosis for patients.
