This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Shen Lin, Peking University

Primary Outcome Measures:
  • circulating tumor cells in blood [ Time Frame: every 6 weeks ]

Enrollment: 138
Study Start Date: June 2012
Study Completion Date: December 2015
Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: cisplatin plus capecitabine
gastric cancer patients treated with capecitabine/cisplatin
Device: CellSearch® CTC kit

Collect peripheral blood sample of 100 gastric cancer patients pre-chemotherapy treated with capecitabine/paclitaxel (XPa) and capecitabine/cisplatin (XP) and post two cycles of chemotherapy(response evaluation).

Blood samples will be transferred to central lab to detect CTCs by Cellsearch 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.
