Brief Summary

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

To identify the correlation of HER2 expression in tissue and peripheral CTC. to identify the HER2 expression in CTCs with clinical prognosis in advanced/metastatic gastric cancer.

Confirm the presence of CTCs are sensitive for monitoring response to chemotherapy.

chemotheropy

Group Type EXPERIMENTAL

Cell Search® CTC epithelial kit

Intervention Type DEVICE

Collect peripheral blood sample of 50 gastric cancer patients pre-chemotherapy and post two cycles of chemotherapy(response evaluation).

Blood samples will be transferred to central lab to detect HER2 positive CTCs by Cellsearch epithelial kit.

Tumor response evaluation will be performed after two cycles of chemotherapy by CT/MRI based on RECIST. Clinical data, including tumor stage, metastastic organ, chemotherapy regimen, objective response, progression free survival, overall survival, etc, will be collected according to study protocol.
