Summary
Brief summary (as posted)
In resectable gastric cancer participants who received curative surgery, to early and more accurately detect peritoneal carcinomatosis or occult metastasis is important. Also, investigators will look at CTC numbers in different timings after operation, to investigate the possibility of early detection for peritoneal carcinomatosis or occult metastasis. Also, this study will correlate the relationship of CTC and participants' survival.
