This paper aims to explore the expression and clinical significance of Ki67 and LRP in gastric cancer. Through a review and analysis of relevant literature in recent years, it was found that the expression level of Ki67 and LRP in gastric cancer was significantly increased, which was closely related to the malignancy of gastric cancer. Ki67 plays an important role in the molecular pathological diagnosis of gastric cancer, which can predict the survival rate and prognosis of patients. Meanwhile, LRP is a membrane glycoprotein associated with multiple tumors, which also plays an important role in gastric cancer. Its level of expression is closely related to the invasion and metastasis of gastric cancer cells.The research found that the increased expression of Ki67 and LRP in gastric cancer can be used as a biomarker to predict the prognosis and therapeutic effect of gastric cancer. To further clarify the molecular mechanism of gastric cancer, this provides a new research direction to improve the diagnosis 精品文档---下载后可任意编辑and treatment level of cases, and is expected to provide a basis for the early diagnosis and prevention of gastric cancer.【Keywords】Gastric cancer, Ki67, LRP, expression, biomarker
