Abstract
Acute myeloid leukemia (AML) is the second most common hematologic malignancy in children. The incidence of childhood AML is much lower than acute lymphoblastic leukemia (ALL), which makes childhood AML a rare disease in children. The role of genetic abnormalities in AML classification, management, and prognosis prediction is much more important than before. Disease classifications and risk group classifications, such as the WHO classification, the international consensus classification (ICC), and the European LeukemiaNet (ELN) classification, were revised in 2022. The application of the new information in childhood AML will be upcoming in the next few years. The frequency of each genetic abnormality in adult and childhood AML is different; therefore, in this review, we emphasize well-known genetic subtypes in childhood AML, including core-binding factor AML (CBF AML), KMT2Ar (KMT2A/11q23 rearrangement) AML, normal karyotype AML with somatic mutations, unbalanced cytogenetic abnormalities AML, NUP98 11p15/NUP09 rearrangement AML, and acute promyelocytic leukemia (APL). Current risk group classification, the management algorithm in childhood AML, and novel treatment modalities such as targeted therapy, immune therapy, and chimeric antigen receptor (CAR) T-cell therapy are reviewed. Finally, the indications of hematopoietic stem cell transplantation (HSCT) in AML are discussed.

Abstract
BACKGROUND Treatment-related myelodysplastic syndrome (t-MDS) is a rare late effect of cancer therapy. After alkylating agents, this typically occurs years after completion of therapy. Treatment of t-MDS in pediatrics is an allogeneic stem cell transplant, however, the prognosis remains poor. OBSERVATIONS This case demonstrates t-MDS developing in a patient receiving treatment for pre-B acute lymphoblastic leukemia. This patient was treated with a combination of hematopoietic stem cell transplant and hypomethylating agents. CONCLUSIONS These agents should be considered for use in patients with t-MDS, before transplant to limit additional chemotherapy and as maintenance therapy post-transplant to reduce the risk of relapse.

Abstract
Long-term outcomes after allogeneic hematopoietic cell transplantation (HCT) for therapy-related myeloid neoplasms (tMNs) are dismal. There are few multicenter studies defining prognostic factors in pediatric patients with tMNs. We have accumulated the largest cohort of pediatric patients who have undergone HCT for a tMN to perform a multivariate analysis defining factors predictive of long-term survival. Sixty-eight percent of the 401 patients underwent HCT using a myeloablative conditioning (MAC) regimen, but there were no statistically significant differences in the overall survival (OS), event-free survival (EFS), or cumulative incidence of relapse and non-relapse mortality based on the conditioning intensity. Among the recipients of MAC regimens, 38.4% of deaths were from treatment-related causes, especially acute graft versus host disease (GVHD) and end-organ failure, as compared to only 20.9% of deaths in the reduced-intensity conditioning (RIC) cohort. Exposure to total body irradiation (TBI) during conditioning and experiencing grade III/IV acute GVHD was associated with worse OS. In addition, a diagnosis of therapy-related myelodysplastic syndrome and having a structurally complex karyotype at tMN diagnosis were associated with worse EFS. Reduced-toxicity (but not reduced-intensity) regimens might help to decrease relapse while limiting mortality associated with TBI-based HCT conditioning in pediatric patients with tMNs.

Abstract
Pegylated liposomal doxorubicin (Peg-Dox) treatment resulted in a good outcome for patients with lymphoma and multiple myeloma, with reduced cardiotoxicity and an improved pharmacokinetic profile when compared to those of conventional doxorubicin. However, the use of Peg-Dox in myeloid neoplasms remains poorly studied. In this study, we first tested the role of Peg-Dox in the killing of myeloid cell lines and of primary myeloid leukemia cells. Then, a Peg-Dox-based protocol was used to treat patients with myeloid neoplasms. The results showed that the Peg-Dox and Peg-Dox-based protocols had a similar killing ability in myeloid cell lines and in primary myeloid leukemia cells compared to that of conventional doxorubicin. The complete remission rate was 87.5% and 100% for patients with refractory/relapsed acute myeloid leukemia and myelodysplastic syndrome with excess blasts, respectively, after treatment with Peg-Dox. All patients developed grade 3 or 4 hematological toxicity and recovered approximately 2 weeks after completing chemotherapy. No deaths or other severe complications were reported. Our results showed that Peg-Dox can be used in the treatment of myeloid neoplasms with high rates of complete remission and with mild complications.

Abstract
The novel aminopeptidase potentiated alkylating agent melflufen, was evaluated for activity in acute myeloid leukemia in a range of in vitro models, as well as in a patient derived xenograft study. All tested AML cell lines were highly sensitive to melflufen while melphalan was considerably less potent. In the HL-60 cell line model, synergy was observed for the combination of melflufen and cytarabine, an interaction that appeared sequence dependent with increased synergy when melflufen was added before cytarabine. Also, in primary cultures of AML cells from patients melflufen was highly active, while normal PBMC cultures appeared less sensitive, indicating a 7-fold in vitro therapeutic index. Melphalan, on the other hand, was only 2-fold more potent in the AML patient samples compared with PBMCs. Melflufen was equally active against non-malignant, immature CD34+ progenitor cells and a more differentiated CD34+ derived cell population (GM14), whereas the stem cell like cells were less sensitive to melphalan. Finally, melflufen treatment showed significant anti-leukemia activity and increased survival in a patient derived xenograft of AML in mice. In conclusion, melflufen demonstrates high and significant preclinical activity in AML and further clinical evaluation seem warranted in this disease.

Abstract
Pediatric myelodysplastic syndromes (MDSs) are a heterogeneous group of clonal disorders with an annual incidence of 1 to 4 cases per million, accounting for less than 5% of childhood hematologic malignancies. MDSs in children often occur in the context of inherited bone marrow failure syndromes, which represent a peculiarity of myelodysplasia diagnosed in pediatric patients. Moreover, germ line syndromes predisposing individuals to develop MDS or acute myeloid leukemia have recently been identified, such as those caused by mutations in GATA2, ETV6, SRP72, and SAMD9/SAMD9-L Refractory cytopenia of childhood (RCC) is the most frequent pediatric MDS variant, and it has specific histopathologic features. Allogeneic hematopoietic stem cell transplantation (HSCT) is the treatment of choice for many children with MDSs and is routinely offered to all patients with MDS with excess of blasts, to those with MDS secondary to previously administered chemoradiotherapy, and to those with RCC associated with monosomy 7, complex karyotype, severe neutropenia, or transfusion dependence. Immune-suppressive therapy may be a treatment option for RCC patients with hypocellular bone marrow and the absence of monosomy 7 or a complex karyotype, although the response rate is lower than that observed in severe aplastic anemia, and a relevant proportion of these patients will subsequently need HSCT for either nonresponse or relapse.

Abstract
Therapy-related acute myeloid leukemia (t-AML) has a dismal prognosis and is one of the most frequent second malignant neoplasms which could be encountered by pediatric oncologists. Between October 2000 and September 2016, 16 patients who had primary solid tumors were diagnosed with t-AML at the Seoul National University Children's Hospital. The median patient age at the time of diagnosis of their primary solid tumors was 9.6 years (range, 0.1 to 15.4 y), and that of t-AML was 14.0 years (range, 4.7 to 23.9 y). The median latency period from the end of the primary tumor treatment to the initial diagnosis of t-AML was 29 months (range, 6 to 130 mo). Twelve patients achieved complete remission. Of them, only 7 patients underwent hematopoietic stem cell transplantation (HSCT). The 3-year overall survival (OS) rates and event-free survival rates were 33.7±12.2% and 26.9±11.5% respectively. The patients who underwent HSCT showed favorable 5-year OS rates (57.1±18.7%), whereas the 5-year OS rates of those who did not undergo HSCT was 0%. This study demonstrates that an achievement of complete remission and a subsequent HSCT can be the optimal solution for the treatment of t-AML, and this strategy showed acceptable outcomes.

Abstract
Few effective therapeutic options exist for patients with metastatic paraganglioma (PGL). We report the case of a 16-year-old male who developed acute myeloid leukemia (AML) 30 months following the treatment for metastatic PGL. PGL had been refractory to 131 I-meta-iodobenzylguanidine and temozolomide therapy. However, there was a major reduction in primary tumor allowing its gross total resection, and complete resolution of metastatic disease following AML-directed therapy that included daunorubicin, cytarabine, and etoposide. He remains in remission for both AML and PGL, 48 months post AML chemotherapy. Alternative chemotherapeutic agents should be considered for metastatic PGL resistant to conventional therapy.

Abstract
We conducted a retrospective analysis of outcomes for children and young adults with sAML/sMDS who underwent HSCT at our institution. Thirty-two patients (median age 20 years) with sAML (n=24) and sMDS (n=8) received HSCT between 1990 and 2013. The median time from sAML/sMDS diagnosis to HSCT was 4.1 months (range: 1.2-27.2 months). The transplant regimens were primarily busulfan based (n=19). BM was the primary donor source (n=15). Eleven recipients were transplanted with residual disease. At a median follow-up of 62.3 months (range: 0.4-250.9 months), 14 patients had disease recurrence. Acute GVHD, grade III/IV, occurred in three patients. Causes of death were as follows: disease relapse (n=12), infection (n=2), pneumonia (n=1), pulmonary hemorrhage (n=1), acute GVHD (n=1), and graft failure (n=1). A PS of ≥90% at the time of HSCT had a significant impact on PFS (P=.02). Patients achieving pretransplant primary CR (n=8) and those with sMDS and RA (n=6) had prolonged PFS (P=.04). On multivariate analysis, shorter time to transplantation (≤6 months from diagnosis of sAML/sMDS) was associated with superior OS (P=.0018) and PFS (P=.0005).

Abstract
Busulfan, fludarabine, and melphalan as hematopoietic cell transplant conditioning, was used in 6 patients aged 1 to 19 years with very high-risk myeloid malignancies. This dose regimen had an acceptable toxicity profile resulting in complete donor engraftment even following transplantation of small 2/6 antigen disparate umbilical cord blood grafts. It provided excellent disease control as all patients had high-risk features in terms of cytogenetics, therapy-related leukemia, and/or significant measurable disease before transplant. All patients remain in remission, without acute or chronic graft-versus-host disease with a median follow-up of 24 months. A larger study is indicated to confirm the efficacy and safety of this regimen.

Abstract
Nonmalignant hematologic disorders (NMHD) of childhood comprise a variety of disorders, including acquired severe aplastic anemia and inherited marrow failure syndromes. Patients with high-risk NMHD without matched related donors fare poorly with allogeneic hematopoietic alternative donor stem cell transplantation (allo-HSCT) and are at high risk for developing graft-versus-host disease following unmodified grafts. The authors retrospectively analyzed data on 18 patients affected by NMHD, lacking a human leukocyte antigen (HLA)-identical sibling donor, who underwent an alternative donor allo-HSCT at their institution between April 2005 and May 2013. Fifty percent of the patients had received prior immunosuppressive therapy, 72% had a history of infections, and 56% were transfusion dependent at the time of transplant. Cytoreduction included a combination of 3 of 5 agents: fludarabine, melphalan, thiotepa, busulfan, and cyclophosphamide. Grafts were T-cell depleted. All evaluable patients engrafted. Five died of transplant complications. The cumulative incidence of graft-versus-host disease was 6%. No patient had recurrence of disease. Five-year overall survival was 77%. Age at transplant <6 years was strongly associated with better survival. Based on these results, transplant with chemotherapy-only cytoreductive regimens and T-cell-depleted stem cell transplants could be recommended for patients with high-risk NMHD, especially at a younger age.

Abstract
BACKGROUND Levetiracetam is increasingly used as antiepileptic drug (AED) of choice in children as well as in adults with complex diseases due to its lack of interactions and a large spectrum of action. Secondary graft failure, i.e. loss of donor cells after initial engraftment, is a relatively uncommon but serious and life-theatening complication after pediatric hematopoietic stem cell transplantation. METHODS AND RESULTS We report a case of secondary graft failure after hematopoietic stem cell transplantation for treatment-related myelodysplastic syndrome during antiepileptic treatment with levetiracetam. Exclusion of all other possible etiologies left levetiracetam as the most likely cause of the imminent complete secondary graft failure after hematopoietic stem cell transplantation. Furthermore, the blood cell count improved just a few days after cessation of levetiracetam medication. CONCLUSION Thus, we recommend that in case of secondary graft failure after hematopoietic stem cell transplantation, all possible causes should carefully be excluded, including adverse events through new generation AED agents. Switching to different AEDs with less harming effect on bone marrow function should strongly be considered.

Abstract
PURPOSE Premature musculoskeletal joint failure is a major source of morbidity among childhood cancer survivors. Radiation effects on synovial joint tissues of the skeleton are poorly understood. Our goal was to assess long-term changes in the knee joint from skeletally mature rats that received total-body irradiation while skeletal growth was ongoing. MATERIALS AND METHODS 14 week-old rats were irradiated with 1, 3 or 7 Gy total-body doses of 18 MV X-rays. At 53 weeks of age, structural and compositional changes in knee joint tissues (articular cartilage, subchondral bone, and trabecular bone) were characterized using 7T MRI, nanocomputed tomography (nanoCT), microcomputed tomography (microCT), and histology. RESULTS T2 relaxation times of the articular cartilage were lower after exposure to all doses. Likewise, calcifications were observed in the articular cartilage. Trabecular bone microarchitecture was compromised in the tibial metaphysis at 7 Gy. Mild to moderate cartilage erosion was scored in the 3 and 7 Gy rats. CONCLUSIONS Late degenerative changes in articular cartilage and bone were observed after total-body irradiation in adult rats exposed prior to skeletal maturity. 7T MRI, microCT, nanoCT, and histology identified potential prognostic indicators of late radiation-induced joint damage.
