Acute lymphoblastic leukemia (ALL) survivors are at risk for developing subsequent neoplasms, but there is limited information on long-term risks and risk factors for both subsequent malignant neoplasms (SMNs) and subsequent non-malignant neoplasms (SNMNs). We analyzed long-term risk and risk factors for SMNs and SNMNs among 3291 5-year ALL survivors from the Dutch Childhood Cancer Survivor Study-LATER cohort (1963–2014). We calculated standardized incidence ratios (SIRs) and cumulative incidences and used multivariable Cox proportional hazard regression analyses for analyzing risk factors. A total of 97 survivors developed SMNs and 266 SNMNs. The 30-year cumulative incidence was 4.1% (95%CI: 3.5–5.3) for SMNs and 10.4%(95%CI: 8.9–12.1) for SNMNs. Risk of SMNs was elevated compared to the general population (SIR: 2.6, 95%CI: 2.1–3.1). Survivors treated with hematopoietic stem cell transplantation (HSCT) with total body irradiation (TBI) (HR:4.2, 95%CI: 2.3–7.9), and without TBI (HR:4.0,95%CI: 1.2–13.7) showed increased SMN risk versus non-transplanted survivors. Cranial radiotherapy (CRT) was also a risk factor for SMNs (HR:2.1, 95%CI: 1.4–4.0). In conclusion, childhood ALL survivors have an increased SMN risk, especially after HSCT and CRT. A key finding is that even HSCT-treated survivors without TBI treatment showed an increased SMN risk, possibly due to accompanied chemotherapy treatment. This emphasizes the need for careful follow-up of HSCT and/or CRT-treated survivors.

儿童急性淋巴细胞白血病 5 岁幸存者造血干细胞移植后后续肿瘤风险增加



急性淋巴细胞白血病 (ALL) 幸存者有发生后续肿瘤的风险,但关于后续恶性肿瘤 (SMN) 和后续非恶性肿瘤 (SNMN) 的长期风险和风险因素的信息有限。我们分析了荷兰儿童癌症幸存者研究-LATER 队列 (1963-2014) 中 3291 名 5 年 ALL 幸存者的 SMNs 和 SNMNs 的长期风险和风险因素。我们计算了标准化发病率比 (SIR) 和累积发病率,并使用多变量 Cox 比例风险回归分析来分析风险因素。共有 97 名幸存者发生 SMN 和 266 例 SNMN。SMN 的 30 年累积发生率为 4.1%(95%CI:3.5-5.3),SNMN 为 10.4%(95%CI:8.9-12.1)。与一般人群相比,SMN 的风险升高(SIR:2.6,95%CI:2.1-3.1)。接受造血干细胞移植 (HSCT) 联合全身照射 (TBI) (HR:4.2,95%CI: 2.3-7.9) 和无 TBI (HR:4.0,95%CI: 1.2-13.7) 治疗的幸存者显示 SMN 风险增加与未移植的幸存者相比。颅放疗 (CRT) 也是 SMN 的危险因素 (HR:2.1,95%CI: 1.4-4.0)。总之,儿童 ALL 幸存者 SMN 风险增加,尤其是在 HSCT 和 CRT 之后。一个关键的发现是,即使是未经 TBI 治疗的 HSCT 治疗幸存者也显示出 SMN 风险增加,这可能是由于伴随化疗。这强调了对 HSCT 和/或 CRT 治疗的幸存者进行仔细随访的必要性。
