研究目的:

18F-FDG PET/CT在弥漫大B淋巴瘤含维泊妥珠单抗(Pola)的治疗方案预后及疗效预测中的价值研究,基于DLBCL患者PET/CT影像资料,采用半自动勾画病灶,提取代谢参数SUVmax(所有病变中测量的最高SUVmax值)、SUVmean(所有病变的平均标准化摄取值)、代谢肿瘤体积(MTV)、总病变糖酵解(TLG)、最大病灶间距(Dmax)及影像组学高通量纹理分析,结合患者临床指标,分析其对含Pola治疗方案的疗效预测及疗效评价能力。为临床提供更为科学和准确的疗效评价及疗效预测。  

Objectives of Study:

This study aims to investigate the prognostic and efficacy predictive value of 18F-FDG PET/CT in DLBCL patients receiving Pola-containing regimens. Based on PET/CT imaging data of DLBCL patients, semi-automatic lesion segmentation will be performed to extract metabolic parameters including SUVmax (the maximum standardized uptake value across all lesions), SUVmean (the mean standardized uptake value of all lesions), metabolic tumor volume (MTV), total lesion glycolysis (TLG), and maximum lesion diameter (Dmax), as well as radiomic high-throughput texture analysis. Combined with patients' clinical indicators, the study will assess the efficacy prediction and evaluation capabilities of these parameters for Pola-containing treatment regimens, thereby providing more scientific and accurate efficacy evaluation and prediction for clinical practice.
