The enrolled population was screened by gastric surgery, including gastric cancer, precancerous lesions, benign lesions, and healthy control group. 10ml of whole blood of the enrolled subjects was collected for multi-target PCR detection of cfDNA methylation. The objective is to explore the clinical performance of polygene methylation (PCR-fluorescence probe) in the adjunctive diagnosis of gastric cancer, including the sensitivity of detection of various types and stages of gastric cancer, the specificity of detection of healthy controls, precancerous states, precancerous lesions, and the detection interference of other cancers. The diagnostic performance will be compared with CA199, CEA and CA724. The research data will provide a basis for screening targets for the development of detection kits.', 'detailedDescription': "Design and plan of the project: 1) Using the MONOD patent detection data of the company's previous research and combining with literature retrieval, analyze the tissue samples of gastric cancer of different stages and their paired paracancer tissues to screen the methylation mutation sites related to early gastric cancer and select the sites suitable for PCR detection; 2) ctDNA methylation markers in gastric cancer blood were preliminarily screened by plasma of healthy persons and preoperative plasma paired with tissues; 3) Using the screened blood ctDNA specific methylation markers, a targeted detection method for early gastric cancer lesions was designed; 4) The detection performance of the independent validation set sample confirmation establishment method."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Eligible participants were recruited from the Department of Gastrosurgery, Fudan University Cancer Hospital, including gastric cancer, precancerous lesions of gastric cancer, other gastric lesions, no abnormalities in gastroscopy, and other cancers.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
