摘要

弥漫性大b细胞淋巴瘤（DLBCL）是一种侵袭性的但有可能治愈的淋巴细胞恶性肿瘤，需要及时治疗。我们调查了个体社会经济地位和家庭区域水平（生态）因素对DLBCL患者诊断至治疗间隔（DTI）的影响，重点关注法国现实世界队列（REALYSA）的极端延迟。方法采用多中心前瞻性队列分析新诊断的DLBCL患者。DTI定义为从确诊到一线治疗之间的持续时间（以天为单位）。使用多项模型将短DTI和长DTI（第10百分位数）与中间DTI进行比较，以确定与极端DTI相关的因素。考虑了社会人口统计数据（包括性别、教育、就业、婚姻状况、社会支持（SSQ6-score）……）和生态特征（法国剥夺指数、当地全科医生的可及性）。结果在889例新诊断的DLBCL患者中（中位年龄66岁，49 % aaIPI≥1,35 % b症状，33 %大体积疾病），中位DTI为25天（四分位数间距：15-39天）。极端dti的第10百分位和第90百分位分别为<； 8和>； 50天。在多变量分析中，与短DTI相关的因素包括aaIPI （OR=3.03, CI95 %[1.44-6.41]）、大体积疾病（OR=3.06, CI95 %[1.68-5.58]）和B症状（OR=2.35, CI95 %[1.30-4.25]），这表明对侵袭性症状需要加快治疗。相反，与长DTI相关的因素包括年龄较大（or >80 y = 3.31,CI95 %[1.39-7.89]），蓝领工人或农民（or =2.36, CI95 %[1.18-4.73]），或在活检和初始治疗之间改变治疗设备类型。在这个新诊断的DLBCL患者的大型现实队列中，年龄、职业状况和患者的途径与治疗延误时间很长有关。简化dti的干预措施，特别是对老年人和/或蓝领或农民患者，以及那些改变治疗设施的患者，有必要提高护理质量。

Impact of socioeconomic individual and ecological factors on extreme diagnosis-to-treatment interval in diffuse large B-Cell lymphoma in the French real-world cohort REALYSA

Introduction

Diffuse large B-cell lymphoma (DLBCL) is an aggressive though potentially curable lymphoid malignancy requiring timely treatment initiation. We investigated the impact of individual socioeconomic status and home area-level (ecological) factors on the diagnosis-to-treatment interval (DTI) in DLBCL patients, focusing on extreme delays in a French real-world cohort (REALYSA).

Methods

We analyzed patients with newly diagnosed DLBCL in the multicentric prospective cohort. DTI was defined as a duration in days between diagnosis confirmation and first-line therapy. Short and long DTIs (10th percentiles) were compared to intermediate DTI using multinomial models to identify factors associated with extreme DTIs. Socio-demographic data (including sex, education, employment, marital status, social support (SSQ6-score)…) and ecological characteristics (French deprivation index, local accessibility to general practitioners) were considered.

Results

Among 889 newly diagnosed DLBCL patients (median age 66 years, 49 % with aaIPI ≥1, 35 % with B-symptoms, 33 % with bulky disease), median DTI was 25 days (interquartile range: 15–39 days). The 10th- and 90th-percentile for extreme DTIs were < 8 and > 50 days respectively. In multivariable analysis, factors associated with short DTI included aaIPI (OR=3.03, CI95 %[1.44–6.41]), bulky disease (OR=3.06, CI95 %[1.68–5.58]), and B symptoms (OR=2.35, CI95 %[1.30–4.25]) - indicating expedited treatment for aggressive presentations. Conversely, factors associated with long DTI included older age (OR>80 y = 3.31, CI95 %[1.39–7.89]), being a blue-collar worker or farmer (OR=2.36, CI95 %[1.18–4.73]), or changing type of treatment facility between biopsy and initial treatment.

Conclusion

In this large real-world cohort of newly diagnosed DLBCL patients, age, occupational status, and patients’ pathway were linked to very long delays to treatment. Interventions to streamline DTIs, especially for older and/or blue-collar or farmer patients, and for those changing facility of treatment, are warranted to improve quality of care.
