摘要:

目的 探讨18F-脱氧葡萄糖(FDG)PET/CT最大标准摄取值(SUVmax)与成人Still病(AOSD)活动度及复发风险之间的相关性。方法 回顾性分析2019年6月—2023年12月在天津市人民医院接受18F-FDG PET/CT检查的17例AOSD患者资料。采用Spearman等级相关分析患者淋巴结、脾脏、骨髓SUVmax与实验室指标及系统性评分的相关性,淋巴结SUVmax与最大短径的相关性。根据随访结果将患者分为复发组与非复发组,比较2组SUVmax、系统性评分、临床特征的差异。结果 17例AOSD患者脾脏、骨髓及淋巴结均出现18F-FDG摄取增高,2例(11.76%)患者伴双侧腮腺(SUVmax 2.3、4.3)、1例(5.88%)伴双侧肘关节、腕关节、手关节及左侧踝关节(SUVmax 3.9)、1例(5.88%)伴双侧颌下腺(SUVmax 3.4)18F-FDG摄取增高。脾脏及骨髓SUVmax与C反应蛋白水平呈正相关(rs分别为0.575、0.549,P<0.05)。淋巴结SUVmax与最大短径呈正相关(rs=0.522,P<0.05)。脾脏、骨髓及淋巴结SUVmax与系统性评分无相关性(rs分别为-0.126、0.100、0.007,P>0.05)。复发组(9例)患者的脾脏SUVmax[5.20(4.45,6.05)]高于非复发组(8例)SUVmax[3.80(2.70,4.00),P<0.05]。结论 18F-FDG PET/CT可作为评估AOSD活动度及预测疾病复发的有用工具,尤其是脾脏SUVmax在预测复发方面显示出潜在的临床价值。

Abstract:

Objective To investigate the correlation between the maximum standardized uptake value(SUVmax) of 18F-fluorodeoxyglucose(FDG)PET/CT and clinical disease activity score as well as recurrence risk of adult-onset Still's disease (AOSD). Methods A retrospective analysis was conducted on 17 patients with AOSD who underwent 18F-FDG PET/CT at Tianjin Union Medicine Center from June 2019 to December 2023. Spearman rank correlation analysis was performed to analyze the relationship between SUVmax of lymph nodes, spleen and bone marrow with clinical disease activity score and laboratory parameters, and those between lymph node SUVmax and maximum short-axis diameter. Patients were divided into the recurrent group and the non-recurrent group based on follow-up results. The differences in SUVmax, clinical disease activity score and clinical features were assessed between the two groups. Results All 17 patients showed 18F-FDG uptake in spleen, bone marrow and lymph nodes. Additionally, 2 patients (11.76%) showed increased 18F-FDG uptake in bilateral parotid glands (SUVmax 2.3, 4.3),1 patient (5.88%) showed increased 18F-FDG uptake in bilateral elbows, wrists, hand joints, and left ankle(SUVmax 3.9), and 1 patient (5.88%) showed increased 18F-FDG uptake in bilateral submandibular glands(SUVmax 3.4). The SUVmax of spleen and bone marrow were positively correlated with C-reactive protein levels(rs value:0.575 and 0.549; both P<0.05), while the SUVmax of lymph nodes was positively associated with their maximum short-axis diameter(rs value:0.522, P<0.05). There was no significant correlation between disease activity score and SUVmax in spleen, bone marrow, or lymph nodes (rs value: -0.126, 0.100 and 0.007,P>0.05). The SUVmax of spleen in the recurrence group (9 patients) was 5.20 (4.45, 6.05), which was significantly higher than that in the non-recurrence group [8 patients, 3.80 (2.70, 4.00), P<0.05]. Conclusion 18F-FDG PET/CT is a valuable tool for assessing AOSD disease activity and predicting disease recurrence, especially the SUVmax of spleen, which shows potential clinical value in predicting recurrence.
