研究目的: |
1.筛选双表达淋巴瘤(DEL)的独立预后因素: 分析病理学特征、18F-FDG PET/CT重要参数及PET/CT影像组学参数在DEL预后中的价值,筛选出独立预后因素; 2.揭示DEL预后不良行为的机制: 揭示c-Myc、Bcl-2指数的线性变化与PET/CT重要参数的相关性,从细胞代谢、迁徙性、传播特点等方面解释高危患者具有更差预后不良的病理行为; 3.基于影像组学构建标准化预后预测模型,并进行前瞻性验证: 为DEL患者治疗前危险分层和制定个性化治疗方案提供依据,以期改善患者预后。 |

|
Objectives of Study: |
1. Identify independent prognostic factors for double-expression lymphoma (DEL): Analyze the value of pathological features, important parameters of 18F-FDG PET/CT, and PET/CT radiomics parameters in the prognosis of DEL, and select independent prognostic factors; 2. Uncover the mechanism of poor prognosis in DEL: Explain the linear relationship between c-Myc and Bcl-2 indices and the important parameters of PET/CT, and explain the pathological behaviors with worse prognosis in high-risk patients from aspects such as cell metabolism, migratory ability, and dissemination characteristics; 3. Build a standardized prognostic prediction model based on radiomics and conduct prospective validation: Provide a basis for risk stratification before treatment and the formulation of individualized treatment plans for DEL patients, with the aim of improving patient prognosis. |
