Plasma cell-free DNA from early stage gastric cancer patients and healthy individuals will be subjected to whole-genome sequencing. Features, such as cell-free DNA fragmentation, copy number variations and microbiome, will be assessed to generate this model.', 'detailedDescription': 'Improvement in the specificity of early cancer detection reduces financial and mental burdens from unnecessary screenings. Advances in liquid biopsy approaches have expanded the clinical scope of cell-free DNA analysis in cancer early detection, by moving away from cell-free DNA methylome toward an integrative approach that enables the simultaneous assessment of multimodal cell-free DNA features. Integration of liquid biopsy-based cancer early detection into the clinic requires optimization of detection techniques, large-scale studies and prospective clinical validation. In the early detection of gastric cancer, the top research priorities are to identify relevant target features and to improve the sensitivity and specificity of detection. This large-scale early detection study will randomly enroll 200 stage I/II pathologically diagnosed gastric patients and 100 age- and sex-matched healthy individuals upon providing written informed consent. Plasma samples will be collected and extracted cell-free DNA will be subjected to whole genome sequencing. We aimed to incorporate genome-wide copy number variations, cell-free DNA fragmentomics, and microbiome features into the development of a multimodal biomarker-based prediction model.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Approximately 200 stage I/II gastric cancer patients and 100 non-cancer controls', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Age minimum 18 years\n* Participants must have histologically and/or cytologically confirmed stage I/II gastric cancer\n* Full access to the patients' clinical and pathological records\n* Ability to understand and the willingness to sign a written informed consent document\n* Non-cancer controls are sex- and age-matched individuals without presence of any tumors or nodules or any other severe chronic diseases through systematic screening\n\nExclusion Criteria:\n\n* Participants must not be pregnant or breastfeeding\n* Participants must not have prior cancer histories or a second non-gastric malignancy\n* Participants must not have had any form of cancer treatment before enrollment or plasma collection, including surgery, chemotherapy, radiotherapy, targeted therapy and immunotherapy\n* Participants must not present medical conditions of fever or have acute or immunological diseases that required treatment 14 days before plasma collection\n* Participants who underwent organ transplant or allogenic bone marrow or hematopoietic stem cell transplantation\n* Participants with clinically important abnormalities or conditions unsuitable for blood collection\n* Any uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, myocardial infarction, major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, or psychiatric illness/social situations that would limit compliance with study requirements or influence patient signing the written informed consent"}, 'identificationModule': {'nctId': 'NCT05269056', 'briefTitle': 'Early Detection of Gastric Cancer Using Plasma Cell-free DNA Fragmentomics', 'organization': {'class': 'OTHER', 'fullName': 'Zhejiang Cancer Hospital'}, 'officialTitle': 'Early Detection of Stage I-II Gastric Cancer Using Plasma Cell-free DNA Fragmentomics', 'orgStudyIdInfo': {'id': 'IRB-2021-295'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Stage I-II gastric cancer', 'description': 'Cell-free DNA collected from plasma samples of 200 patients with stage I-II gastric cancer will undergo whole-genome sequencing'}, {'label': 'Healthy controls', 'description': 'Cell-free DNA collected from plasma samples of 100 non-cancer individuals will serve as controls'}]}, 'contactsLocationsModule': {'locations': [{'zip': '310022', 'city': 'Hangzhou', 'state': 'Zhejiang', 'status': 'RECRUITING', 'country': 'China', 'contacts': [{'name': 'Pengfei Yu, MD，PhD', 'role': 'CONTACT', 'email': 'ypfzmu@163.com', 'phone': '+86-571-88128031'}, {'name': 'Xiangdong Cheng, MD，PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Yu Pengfei, MD，PhD', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Zhejiang Cancer Hospital；Cancer hospital of the university of chinese academy of sciences', 'geoPoint': {'lat': 30.29365, 'lon': 120.16142}}], 'centralContacts': [{'name': 'Pengfei Yu, MD, PhD', 'role': 'CONTACT', 'email': 'ypfzmu@163.com', 'phone': '86-571-88128031'}], 'overallOfficials': [{'name': 'Xiangdong Cheng, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Zhejiang Cancer Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Zhejiang Cancer Hospital', 'class': 'OTHER'}, 'collaborators': [{'name': 'Nanjing Geneseeq Technology Inc.', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'MD', 'investigatorFullName': 'Xiangdong Cheng', 'investigatorAffiliation': 'Zhejiang Cancer Hospital'}}}}
