Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study was to investigate the expression of ZEB1 in CTCs for gastric cancer, its correlation with the clinicopathology of gastric cancer, and the role of ZEB1 in invasion and metastasis in gastric cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Invasion and metastasis of tumors and postoperative recurrence are the main causes of death in patients with gastric cancer and are also the key factors affecting the clinical treatment and prognosis.

In this study, the investigators will detect the expression of ZEB1 in different types of CTCs(epithelial,mesenchymal and mixed phenotype) for gastric cancer by CanPatrolTM2 detection technology.Our investigation of the relationship between ZEB1 and the occurrence and development as well as the invasion and metastasis of gastric cancer is expected to provide data for the prognosis and targeted therapy of gastric cancer.

Approximate 100 consecutive patients with gastric cancer and CTCs(+) will be enrolled in this study.Detection of ZEB1 expression in CTCs at baseline will show the relationship between ZEB1 and clinicopathological variables. Postoperative follow-up of ZEB1 expression in CTCs will be performed every three months in the first year and every six months in the following two years. The results may indicate the role of ZEB1 in CTCs about invasion and metastasis for gastric cancer .The aim of this study is to clarify the clinical significance of ZEB1 expression in CTCs for gastric cancer.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ZEB1 high-expression group

Participants with ZEB1 high-expression(ZEB1 expression values\>the ZEB1 cut-off point) in CTCs for gastric cancer will be assigned to this group.The ZEB1 cut-off point was set at the top quartile.Routine comprehensive treatment will be performed.

Routine comprehensive treatment

Intervention Type PROCEDURE

Radical gastrectomy for gastric cancer and postoperative adjuvant chemotherapy

ZEB1 low-expression group

Participants with ZEB1 low-expression(ZEB1 expression values\<the ZEB1 cut-off point) in CTCs for gastric cancer will be assigned to this group.The ZEB1 cut-off point was set at the top quartile.Routine comprehensive treatment will be performed.
