Quantitative Detection of CEA mRNA in the Smog and Tissue Exudate Whole Process Collected During Laparoscopic (Robotic) Radical Gastrectomy in Gastric Cancer Patients: Study Protocol for a Single Center Prospective, Single-arm, Longitudinal Pilot Study（SMOG 01Study）
The purpose of this SMOG 01 study is to observe the possibility of intraperitoneal dissemination of tumor cells throughout the entire laparoscopic (robotic) radical gastrectomy for gastric cancer and explore its related mechanisms and potential clinical significance with peritoneal metastasis.
• Gastric adenocarcinoma confirmed by preoperative pathology
• Endoscopic and CT/MRI enhanced examination confirmed that cT1-4aN0-3M0 has the possibility of resection
• To undergo radical gastrectomy (laparoscopic or robotic) under general anesthesia+/- epidural anesthesia (carbon dioxide pneumoperitoneum)
• Willing and able to comply with the research protocol
• Reach a written consent agreement before registration, and fully realize the right to withdraw from the study at any time without any loss
