Summary
Brief summary (as posted)
The investigators study aims to explore the potential function of extensive intraoperative peritoneal lavage in improving the overall survival and progression-free survival for locally advanced gastric cancer after curative resection. Hypothesis: Overall survival and progression-free survival of locally advanced gastric cancer are improved by extensive intraoperative peritoneal lavage.
