Background: The etiology of non-Hodgkin lymphoma (NHL) in children and in adolescents and young adults (AYA) is not well understood. Methods: We evaluated potential associations between mode of delivery, birth characteristics, and NHL risk in a population-based case–control study, which included 3,064 cases of NHL [490 with Burkitt lymphoma, 981 with diffuse large B-cell lymphoma (DLBCL), and 978 with T-cell NHL) diagnosed at the age of 0 to 37 years in California during 1988 to 2015 and 153,200 controls frequency matched on year of birth. Odds ratios (OR) and 95% confidence intervals (CI) were estimated from an unconditional multivariable logistic regression model that included year of birth and birth characteristics. Results: Individuals born via cesarean section had a decreased risk of pediatric Burkitt lymphoma (age 0–14 years; OR = 0.71, 95% CI: 0.51–0.99) and pediatric T-cell NHL (OR = 0.73, 95% CI: 0.55–0.97) compared with those born vaginally. Having a birth order of second (OR = 0.73, 95% CI: 0.57–0.93) or third or higher (OR = 0.76, 95% CI: 0.58–0.99) was associated with a lower risk of pediatric T-cell NHL compared with first-borns. AYA (age 15–37 years) with a heavier birthweight had an elevated risk of DLBCL (OR for each kg = 1.16, 95% CI: 1.00–1.35). Associations between other birth characteristics, including plurality, maternal age, maternal education, and NHL risk, also exhibited variations across subgroups based on age of diagnosis and histologic subtype. Conclusions: These findings support a role of mode of delivery and birth characteristics in the etiology of early-onset NHL. Impact: This study underscores the etiologic heterogeneity of early-onset NHL.

基于人群的病例对照研究中的分娩方式、出生特征和早发性非霍奇金淋巴瘤

背景:儿童、青少年和年轻人 (AYA) 中非霍奇金淋巴瘤 (NHL) 的病因尚不清楚。方法:我们在一项基于人群的病例对照研究中评估了分娩方式、出生特征和 NHL 风险之间的潜在关联,该研究包括 3,064 例 NHL [490 例 Burkitt 淋巴瘤,981 例弥漫性大 B 细胞淋巴瘤 (DLBCL)和 978 例 T 细胞 NHL)在 1988 年至 2015 年期间在加利福尼亚州被诊断为 0 至 37 岁,并且 153,200 名对照频率与出生年份匹配。优势比 (OR) 和 95% 置信区间 (CI) 是根据包括出生年份和出生特征的无条件多变量逻辑回归模型估计的。结果:通过剖宫产出生的个体患小儿伯基特淋巴瘤的风险降低(年龄 0-14 岁;OR = 0.71,95% CI:0.51-0.99)和小儿 T 细胞 NHL(OR = 0.73,95% CI:0.55-0.97)与阴道出生的人相比。出生顺序为第二(OR = 0.73, 95% CI: 0.57–0.93)或第三或更高(OR = 0.76, 95% CI: 0.58–0.99)与儿童 T 细胞 NHL 的风险较低相关长子。出生体重较重的 AYA(年龄 15-37 岁)发生 DLBCL 的风险升高(OR 每公斤 = 1.16,95% CI:1.00-1.35)。其他出生特征之间的关联,包括复数、母亲年龄、母亲教育和 NHL 风险,也表现出基于诊断年龄和组织学亚型的亚组之间的差异。结论:这些发现支持分娩方式和出生特征在早发性 NHL 病因学中的作用。影响: 本研究强调了早发性 NHL 的病因异质性。99) 和小儿 T 细胞 NHL (OR = 0.73, 95% CI: 0.55–0.97) 与阴道出生的人相比。出生顺序为第二(OR = 0.73, 95% CI: 0.57–0.93)或第三或更高(OR = 0.76, 95% CI: 0.58–0.99)与儿童 T 细胞 NHL 的风险较低相关长子。出生体重较重的 AYA(年龄 15-37 岁)发生 DLBCL 的风险升高(OR 每公斤 = 1.16,95% CI:1.00-1.35)。其他出生特征之间的关联,包括复数、母亲年龄、母亲教育和 NHL 风险,也表现出基于诊断年龄和组织学亚型的亚组之间的差异。结论:这些发现支持分娩方式和出生特征在早发性 NHL 病因学中的作用。影响: 本研究强调了早发性 NHL 的病因异质性。99) 和小儿 T 细胞 NHL (OR = 0.73, 95% CI: 0.55–0.97) 与阴道出生的人相比。出生顺序为第二(OR = 0.73, 95% CI: 0.57–0.93)或第三或更高(OR = 0.76, 95% CI: 0.58–0.99)与儿童 T 细胞 NHL 的风险较低相关长子。出生体重较重的 AYA(年龄 15-37 岁)发生 DLBCL 的风险升高(OR 每公斤 = 1.16,95% CI:1.00-1.35)。其他出生特征之间的关联,包括复数、母亲年龄、母亲教育和 NHL 风险,也表现出基于诊断年龄和组织学亚型的亚组之间的差异。结论:这些发现支持分娩方式和出生特征在早发性 NHL 病因学中的作用。影响: 本研究强调了早发性 NHL 的病因异质性。
