研究目的: |
主要目的: 系统分析中国南方广州地区EBV相关胃癌合并HP感染的流行病学特征,揭示该区域的病原体共感染模式及其与临床病理特征的关联。探讨EBV和HP在胃癌发生中的协同作用机制,为精准医学领域的多因素致病模型构建提供科学依据。 次要目的:优化EBV相关胃癌合并HP感染的个体化治疗方案,明确共感染对肿瘤分期、免疫微环境及药物敏感性的影响。开发早期筛查和风险评估模型,提高胃癌患者的生存率和生活质量。制定针对性的胃癌防控政策,推动疫苗接种(如HP疫苗)和健康教育的普及,降低胃癌发病率。构建区域性的流行病学数据库,为后续更大规模的研究奠定基础,同时为其他胃癌高发地区提供借鉴。 |

Objectives of Study: |
Primary Objective:To systematically analyze the epidemiological characteristics of EBV-associated gastric cancer with concurrent HP infection in Guangzhou, Southern China, revealing the regional pathogen co-infection patterns and their associations with clinicopathological features. To investigate the synergistic mechanisms of EBV and HP in gastric carcinogenesis, providing scientific evidence for constructing multifactorial pathogenic models in the field of precision medicine.Secondary Objectives: To optimize individualized treatment strategies for EBV-associated gastric cancer with concurrent HP infection, clarifying the impact of co-infection on tumor staging, immune microenvironment, and drug sensitivity. To develop early screening and risk assessment models to improve survival rates and quality of life for gastric cancer patients. To formulate targeted gastric cancer prevention and control policies, promoting the adoption of vaccination (such as HP vaccine) and health education to reduce gastric cancer incidence. To establish a regional epidemiological database, laying the foundation for subsequent larger-scale studies while providing references for other high-incidence gastric cancer regions. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
研究数据计划于主要研究结果发表后12个月内公开共享。原始数据将去除个人身份信息后,通过中国临床试验注册中心数据共享平台或国家医学数据中心进行共享,包括研究方案、统计分析计划及去标识化的个体患者数据(IPD),供符合条件的研究者申请使用。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
De-identified individual participant data (IPD), along with metadata, study protocol, and statistical analysis plan, will be made available within 12 months after publication of the primary results. Data will be shared via the Chinese Clinical Trial Registry (ChiCTR) data sharing platform or the National Medical Data Center, and will be accessible to qualified researchers upon reasonable request. |
|
数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究的数据将通过医院电子病历系统、病理报告、实验室检测报告、影像学检查报告以及随访记录等多种来源进行采集,采集内容包括患者的人口学特征、临床病理特征、病原体检测结果(EBV和HP感染状态)、分子病理学检测结果、实验室指标、影像学检查结果、治疗相关信息以及生存状态和随访信息。数据采集将在基线评估、治疗期间(每3个月)和后续随访期间(每6个月)定期进行。为确保数据质量,研究采用双人独立录入和交叉核对机制,由两名研究人员分别独立录入所有数据后进行比对以确保一致性,并定期进行数据清理和逻辑核查。研究设立独立终点事件判定委员会,采用盲法评估对主要终点(总体生存期)和次要终点(无进展生存期、治疗反应率)进行客观判定。所有数据管理将遵循标准化原则,包括统一采用AJCC第8版TNM分期系统进行肿瘤分期、使用RECIST 1.1标准评估疗效,同时严格执行患者信息去标识化处理和数据安全保密措施,限制数据访问权限,确保符合医疗数据保护规定。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data for this study will be collected from multiple sources including the hospital electronic medical record system, pathology reports, laboratory test reports, imaging examination reports, and follow-up records. The collected data will include patients' demographic characteristics, clinicopathological features, pathogen detection results (EBV and HP infection status), molecular pathology test results, laboratory indicators, imaging examination results, treatment-related information, as well as survival status and follow-up information. Data collection will be conducted regularly at baseline assessment, during the treatment period (every 3 months), and during subsequent follow-up (every 6 months). To ensure data quality, the study will employ dual independent data entry and cross-verification mechanisms, whereby two research personnel will independently enter all data separately and then compare to ensure consistency, with regular data cleaning and logical verification. An independent endpoint adjudication committee will be established to conduct blinded assessments for objective determination of primary endpoints (overall survival) and secondary endpoints (progression-free survival, treatment response rate). All data management will follow standardized principles, including the uniform use of the AJCC 8th edition TNM staging system for tumor staging and the RECIST 1.1 criteria for efficacy evaluation, while strictly implementing patient de-identification procedures and data security and confidentiality measures, restricting data access permissions to ensure compliance with medical data protection regulations. |
