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: |
连续收集患者的基线资料、检验、影像、病理、药物治疗等资料。基线资料包括年龄、性别、透析史、合并疾病、肿瘤病史等;检验资料包括患者术前尿液、血常规、肝肾功能、DIC、血糖、血型、肝炎两对半、肿瘤指标数据等;术后免疫抑制剂诱导方案、维持方案、术后3个月、6个月、12个月排斥药浓度;影像学资料包括移植前及移植后CT、彩超等;药物治疗包括免疫抑制药物使用及合并症治疗药物等。 建立 Nomogram 模型:将回顾性队列患者按照5:3:2 分为模型建立组、内部验证组和外部独立验证组。对模型建立组患者,使用LASSO回归结合术前CT影像组学大数据,筛选可能的影像组学标志物,并结合机器学习优化预测性能,建立Nomogram模型。前瞻性患者队列根据Nomogram评分风险分级,分高、中、低三个风险组。生存曲线、COX多因素分析比较三个组的无肿瘤事件生存率、总体生存率。针对早诊队列,则利用临床大数据,构建基于人工智能的新发肿瘤早诊模型。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Continuously collect patients' baseline data, laboratory tests, imaging, pathology, and medication treatment information. Baseline data include age, gender, dialysis history, comorbidities, and tumor history. Laboratory test data include preoperative urine tests, complete blood count, liver and kidney function, DIC (disseminated intravascular coagulation), blood glucose, blood type, hepatitis B serology, and tumor marker data. Postoperative data include immunosuppressive induction and maintenance regimens, as well as trough levels of immunosuppressive drugs at 3 months, 6 months, and 12 months post-transplantation. Imaging data include pre- and post-transplant CT scans and color Doppler ultrasounds. Medication treatment data include the use of immunosuppressive drugs and medications for managing comorbidities. Establishment of a Nomogram Model: The retrospective cohort will be divided into a model development group, an internal validation group, and an external independent validation group in a 5:3:2 ratio. For the model development group, LASSO regression will be used in combination with preoperative CT radiomics big data to screen potential radiomics biomarkers. Machine learning will be applied to optimize predictive performance and establish a Nomogram model. The prospective patient cohort will be stratified into high-, medium-, and low-risk groups based on Nomogram risk scores. Survival curves and Cox multivariate analysis will be used to compare tumor-free survival rates and overall survival rates among the three groups. For the early diagnosis cohort, clinical big data will be utilized to construct an artificial intelligence-based model for early detection of de novo tumors. |
