Teepen1  \n© The Author(s) 2024  \n\n|  | 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 |  |\n| --- | --- | --- |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n| and/or CRT-treated survivors. |  |  |\n|  | Blood Cancer Journal (2024)14:150; [https://doi.org/10.1038/s41408-024-01](https://doi.org/10.1038/s41408-024-01)122-7 |  |\n|  |  |  |\n\nINTRODUCTION  \nAcute lymphoblastic leukemia (ALL) is the most common typeof childhood cancer [1–3], with a 5-year survival rate currently exceeding 90%[4] . However, ALL survivors are at risk for longterm adverse health outcomes including the development of subsequent neoplasms [5, 6] . Compared to the general population, childhood ALL survivors have a 2.6 to 13.5 times higher risk of developing subsequent malignant neoplasms (SMNs) [5–8] . The most frequently observed SMNs in ALL survivors are central nervous system (CNS) tumors [6, 9] . In addition to SMNs, some types of subsequent non-malignant neoplasms (SNMNs) can also cause serious morbidity, such as subsequent meningiomas [5, 10] .  \nTreatment protocols for ALL patients have changed overtime. Major adjustments in the Netherlands were 1) the substitution of cranial radiotherapy (CRT) by CNS prophylaxis with intrathecal high-dose methotrexate since to the DCOGALL VI protocol in December 1984 [11, 12] and 2) trials with  \nreplacing TBI with a chemotherapy conditioning regimen for HSCT between 2011 and 2021 [13, 14] Several studies examined treatment-related risk factors for subsequent neoplasms in ALL survivors [5, 15–17] . Although many studies were limited by short follow-up times [15–17] or the limited availability of specific treatment data [5, 15–17], several risk factors have been suggested. The risk of developing a subsequent neoplasm was found to be higher in patients","cbCaihMK33i14uNT","https://ap.wps.com/l/cbCaihMK33i14uNT","pdf",734593,"English","# Introduction\n## Study aim and rationale\n# Methods and outcomes\n## Cohort and statistical approach\n## Incidence and risk factors\n# Conclusion and implications","[{\"question\":\"What was the main aim of the study in childhood ALL 5-year survivors?\",\"answer\":\"To quantify long-term risk and identify associated risk factors for subsequent malignant neoplasms (SMNs) and subsequent non-malignant neoplasms (SNMNs).\"},{\"question\":\"How many SMN and SNMN cases were observed, and what were the 30-year cumulative incidences?\",\"answer\":\"A total of 97 survivors developed SMNs and 266 developed SNMNs.
