研究目的: |
1)构建适配国内人群的深度学习模型:基于国内肝癌患者 CT 影像数据,开发并优化深度学习算法,提升对微小病灶(尤其是早期肝癌病灶)的特征提取与识别能力,解决现有模型对本土人群适配性不足的问题。 2)提升 CT 影像筛查效能:通过模型辅助阅片,降低人工阅片的漏诊、误诊率,同时缩短阅片时间,突破传统筛查依赖医师经验、效率低的局限,满足大规模筛查需求。 3)推动基层落地应用:探索模型在基层医疗机构的部署方案,提供轻量化、易操作的辅助筛查工具,弥补基层医疗资源不足的短板,助力肝癌早筛在基层普及。 4)形成可推广的筛查方案:结合模型性能验证结果,构建 “CT 影像 + 深度学习” 的肝癌早筛流程,为临床提供标准化、精准化的筛查参考,推动智能技术与肝癌早筛临床实践深度融合。 |

Objectives of Study: |
1) Build a deep learning model suitable for the domestic population: Based on the CT image data of domestic liver cancer patients, develop and optimize deep learning algorithms to enhance the feature extraction and recognition capabilities for tiny lesions (especially early-stage liver cancer lesions), and address the issue of insufficient adaptability of existing models to the local population. 2) Enhance the efficiency of CT image screening: By using model-assisted film reading, the rates of missed diagnosis and misdiagnosis caused by manual film reading can be reduced, while also shortening the film reading time. This breaks through the limitations of traditional screening that relies on the experience of physicians and is inefficient, meeting the demands of large-scale screening. 3) Promote the application at the grassroots level: Explore the deployment plan of the model in grassroots medical institutions, provide lightweight and easy-to-operate auxiliary screening tools, make up for the shortage of grassroots medical resources, and facilitate the popularization of early screening for liver cancer at the grassroots level. 4) Develop a scalable screening program: Based on the performance verification results of the model, construct a liver cancer early screening process of "CT images + deep learning" to provide standardized and precise screening references for clinical practice and promote the in-depth integration of intelligent technology with clinical practice of liver cancer early screening. |

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: |
病例记录表 (CRF):创建一个标准化的病例记录表,包含所有需要收集的病例信息字段。这可能包括患者的基本信息、临床病史等。确保病例记录表的设计符合研究目的和数据采集要求。字段应清晰明了,便于填写和审核。为每位患者创建一个唯一的标识符,以便在整个数据集中唯一标识每个病例。提供清晰的填写说明,确保研究人员能够正确理解和录入信息。 电子采集和管理系统 (EDC):在EDC系统中设置相应的病例记录表,确保系统能够按照CRF的设计进行数据采集。进行培训,确保研究人员熟悉EDC系统的操作,包括数据录入、修改和审核等功能。实施数据验证规则,以确保数据的完整性和准确性。设置访问权限,保护数据的安全性,确保只有授权人员能够访问和修改数据。 数据采集和管理过程:确保所有参与数据采集和管理的人员都了解研究伦理规范和数据保护法规。定期进行数据监测和质量控制,确保数据的一致性和准确性。保留数据采集过程的详细记录,包括数据修改的原因和日期。遵循相关伦理委员会的规定,确保数据采集和管理的合法性和透明度。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Case Record Form (CRF):Create a standardized Case Record Form that includes all the necessary fields for collecting case information. This may include basic patient information, clinical history, laboratory tests, CT image features, etc. Ensure that the design of the CRF aligns with the research objectives and data collection requirements. Fields should be clear and easy to fill in and review. Assign a unique identifier for each patient to uniquely identify each case throughout the dataset. Provide clear instructions for filling out the CRF, ensuring that researchers can correctly understand and enter information. Electronic Data Capture and Management System (EDC): If collecting data electronically, choose a suitable Electronic Data Capture and Management System (EDC). Common EDC systems include OpenClinica, REDCap, Medidata, etc. Set up the corresponding CRF within the EDC system, ensuring that the system can collect data according to the CRF design. Conduct training to ensure that researchers are familiar with the operation of the EDC system, including data entry, modification, and auditing functions. Implement data validation rules to ensure the integrity and accuracy of the data. Set access permissions to protect the security of the data, ensuring that only authorized personnel can access and modify it. Data Collection and Management Process: Ensure that all personnel involved in data collection and management are familiar with research ethical standards and data protection regulations. Conduct regular data monitoring and quality control to ensure the consistency and accuracy of the data. Keep detailed records of the data collection process, including reasons and dates for data modifications. Follow the regulations of the relevant ethics committees to ensure the legality and transparency of data collection and manageme |
