| 摘要 目的：研究弥漫性大B细胞淋巴瘤患者的ctDNA与PET-CT基线肿瘤参数动态变化以及相关性。方法：将2020.1~2022.2血液科诊治的63例弥漫性大B细胞淋巴瘤患者为观察组，同期22例非肿瘤患者患者为对照组，测定并比较相关指标，并分析相关性。结果：观察组患者的ctDNA、SUVmax、SUVmean、TMTV、TLG高于对照组患者（P＜0.05）；观察组内ctDNA、SUVmax、SUVmean、TMTV、TLG在Ann-Arbor分期中逐渐上升，在不同治疗时间段中逐渐下降（P＜0.05）；Spearman相关性显示：cDNA与SUVmax、SUVmean、TMTV、TLG均呈正相关性（P＜0.05）。结论：弥漫性大B细胞淋巴瘤患者的ctDNA、PET-CT基线肿瘤参数均随着Ann-Arbor分期的上升而升高，化疗疗程的增加而下降，且ctDNA与SUVmax、SUVmean、TMTV、TLG呈正相关性 |

| ABSTRACT Objective: The dynamics and correlation of ctDNA and PET-CT baseline tumor parameters in patients with diffuse large B-cell lymphoma. Methods: 63 patients with diffuse large B cell lymphoma treated by hematology department from 2020.1 to 2022.2 were in the observation group, and 22 non-tumor patients were in the matched group. Relevant indicators were determined and compared, and the correlation was analyzed. Results: The ctDNA, SUVmax, SUVmean, TMTV, and TLG were higher than those in the observation group (P<0.05); ctDNA, SUVmax, SUVmean, TMTV, TLG gradually increased in Ann-Arbor stage and decreased in different treatment periods (P<0.05); Spearman correlation showed positive cDNA with SUVmax, SUVmean, TMTV, and TLG (P<0.05). Conclusion: The baseline tumor parameters of ctDNA and PET-CT in patients with diffuse large B-cell lymphoma increase with the increase of Ann Arbor stage, while decrease with the increase of chemotherapy course. ctDNA is positively correlated with SUVmax, SUVmean, TMTV, TLG. |
