Study design:

Cohort study 

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.

测量指标:

Outcomes:

指标中文名:

PET/CT相关参数(SUVmax、SUVpeak、Dmaxbulk、Dmaxpatient、BVG等;测量欧氏距离、曼哈顿距离、切比切夫距离

指标类型:

主要指标

Outcome:

PET/CT related parameters (SUVmax, SUVpeak, Dmaxbulk, Dmaxpatient, BVG, etc.; measurement of Euclidean distance, Manhattan distance, Chebyshev distance)

Type:

Primary indicator

测量时间点:

基线(治疗前)

测量方法:

用3D Slicer软件测量病灶的质心坐标作为病灶的坐标。测量欧氏距离(Euc):m维空间中两点间的真实距离,在二维或三维空间中,即为两点间的实际距离;曼哈顿距离(Man):两点在南北方向上的距离加上在东西方向上的距离;切比切夫距离(Tch):各坐标数值差绝对值的最大值。用3D Slicer软件分别在PET和CT图像上勾画靶区,进行影像组学特征提取。

Measure time point of outcome:

Baseline (before treatment)

Measure method:

The centroid coordinates of the lesion were measured using 3D Slicer software as the coordinates of the lesion. Measuring Euclidean distance (Euc) : The true distance between two points in an M-dimensional space, and in a two-dimensional or three-dimensional space, it is the actual distance between the two points. Manhattan distance (Man) : The distance between two points in the north-south direction plus the distance in the east-west direction. Chebychev distance (Tch) : The maximum absolute va
