Limited knowledge currently exists on the disparity in pediatric leukemia relapse. This study compared the risk of pediatric leukemia relapse between Hispanic and non-Hispanic Whites. Study participants were children (<20 years) diagnosed with leukemia from January 2006 to December 2014 at the Johns Hopkins All Children's Hospital, St. Petersburg, Florida. Hazard ratios and 95% confidence intervals for relapse-free survival were calculated using adjusted Cox regression. The study included 35 Hispanic and 94 non-Hispanic Whites...

The clinical outcome of children with high-risk relapsed B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is poor. The present study assessed the utility and prognostic value of selected microRNA (miRNA/miR) in BCP-ALL. The changes in the expression levels of these miRNAs regarding known gene lesions affecting lymphoid development [early B-cell factor 1 (EBF1), ETS variant 6 (ETV6), IKAROS family zinc finger 1 (IKZF1), paired box 5 (PAX5), cyclin dependent kinase inhibitor (CDKN) 2A/CDKN2B, retinoblastoma 1 (RB1), pseudoautosomal region 1 (PAR1), B-cell translocation gene 1 protein (BTG1)] were analyzed...

BACKGROUND: Botulism is a potentially fatal infection characterized by progressive muscle weakness, bulbar paralysis, constipation and other autonomic dysfunctions. A recent report suggested that cancer chemotherapy might increase the risk for the intestinal toxemia botulism in both adults and children. CASE PRESENTATION: We report a 5-year-old boy, who developed general muscle weakness, constipation, ptosis and mydriasis during the third induction therapy for relapsed acute myeloid leukemia...

OBJECTIVES: Recent guidelines recommend to assess emotional distress in pediatric oncology during treatment and in after care. One tool used to do this is the distress thermometer (DT), a simple tool which has almost exclusively been studied in its screening abilities. Given its increased used as a measure of distress per se, it is necessary to document its concurrent validity. The goal of this study was to identify clinical domains (eg, depression, anxiety) and individual symptoms associated with pediatric cancer survivors' rating on the DT...

High-dose methotrexate (Hd-MTX) therapy has recently been applied to the treatment of adult acute lymphoblastic leukemia (ALL) based on pediatric protocols; however, its effectiveness for adult ALL has not yet been confirmed in a rigorous manner. We herein conducted a randomized phase III trial comparing Hd-MTX therapy with intermediate-dose (Id)-MTX therapy. This study was registered at UMIN-CTR (ID: C000000063). Philadelphia chromosome (Ph)-negative ALL patients aged between 25 and 64 years of age were enrolled...

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer among children and adolescents in the United States, representing 20% of all cancers diagnosed in persons aged <20 years, or >3,000 new cases each year (1). Past studies reported increasing trends of ALL overall and among Hispanics, but these represented ≤28% of the U.S. population and did not provide state-based estimates (1-3). To describe U.S. ALL incidence rates and trends among persons aged <20 years during 2001-2014, CDC analyzed rigorous data (based on established publication criteria) from the United States Cancer Statistics data set, which includes incidence data on approximately 15,000 new cases per year of all types of invasive cancer among children and adolescents aged <20 years (4)...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive hematologic malignancy characterized by frequent skin involvement that most commonly affects older patients. BPDCN is known to have a poor prognosis. Our objective was to assess if outcome and disease prognosis were independently influenced by age when evaluated with clinical presentation, sex, and treatment regimens. We conducted a systematic review to identify BPDCN cases, to compare pediatric BPDCN cases with adult cases. A total of 125 publications were identified detailing 356 cases...

BACKGROUND AND OBJECTIVES: In pediatric T-cell acute lymphoblastic leukemia (T-ALL) risk assignment schemes preclude reliable prediction of outcome and thus new prognostic factors are needed. Mutations in DNMT3A are candidate prognostic and classification markers in adults with acute myeloid leukemia (AML) and T-ALL and thus were considered as candidates prognostic markers in pediatric T-ALL. PATIENTS AND METHODS: DNMT3A mutational status was investigated in 74 pediatric T-ALL samples collected at diagnosis...

Pediatric cholecystolithiasis is a relatively rare disease, but it is recently increasing in Japan. Laparoscopic cholecystectomy (LC) is a standard procedure for cholecystolithiasis not only in adults but also in children, and we are aggressively introducing single-incision laparoscopic cholecystectomy (SILC) at our hospital. We reviewed the patient characteristics, operation procedures and outcomes of 7 children (15 years old and under) with cholecystolithiasis who underwent LC in our hospital between August 1995 and December 2015...

Neuroblastoma is the most common extracranial malignancy of childhood. Patients with high-risk disease receive multimodal treatment including chemotherapy combinations containing alkylating agents and topoisomerase inhibitors with potential for inducing therapy-related malignancy later in life. Most commonly, cytogenetic changes of pediatric therapy-related myelodysplastic syndrome/acute myeloid leukemia involve chromosome 5 or 7. Here we report a novel case of therapy-related myelodysplastic syndrome/acute myeloid leukemia 30 months after treatment for high-risk neuroblastoma with biphenotypic cell surface markers and a not yet described translocation t(1;6)(q25;p23)...

MLL-rearranged leukemia represents approximately 5% to 10% of adult acute myelogenous leukemia (AML) and nearly half of all infant/pediatric acute leukemia cases. These leukemias have a poor prognosis, and there are no approved therapeutic options. The rearrangement in the MLL gene leads to aberrant expression of MLL-fusion proteins. These are transforming in murine bone marrow and, in particular, on stem cells and myeloid progenitors derived from bone marrow or fetal liver. The commonality of the MLL fusions is the in-frame fusion of 8 to 11 N-terminal exons of MLL1 (KMT2a) with the C-terminus of a partner fusion gene...

In acute myeloid leukemia (AML), specific genomic aberrations induce aberrant methylation, thus directly influencing the transcriptional programing of leukemic cells. Therefore, therapies targeting epigenetic processes are advocated as a promising therapeutic tool for AML treatment. However, to develop new therapies, a comprehensive understanding of the mechanism(s) driving the epigenetic changes as a result of acquired genetic abnormalities is necessary. This understanding is still lacking. In this study, we performed genome-wide CpG-island methylation profiling on pediatric AML samples...

Multiagent chemotherapy, radiotherapy, or a combination of both are the contemporary methods of cancer treatment. With medical advancements, though cure rates have increased considerably, focus is now shifted to the potential early and late complications of the same. The aim of this study was to assess the early oral complications in pediatric patients receiving chemotherapy. Sixty-two children with cancer undergoing chemotherapy with the mean age of 7.42 ± 3.6 years were included in the study. The various types of malignancies and oral problems during chemotherapy were recorded in the subjects...

Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. ALL arises from the malignant transformation of progenitor B- and T-cells in the bone marrow into leukemic cells, but the mechanisms underlying this transformation are not well understood. Recent technical advances and decreasing costs of methods for high-throughput DNA sequencing and SNP genotyping have stimulated systematic studies of the epigenetic changes in leukemic cells from pediatric ALL patients. The results emerging from these studies are increasing our understanding of the epigenetic component of leukemogenesis and have demonstrated the potential of DNA methylation as a biomarker for lineage and subtype classification, prognostication, and disease progression in ALL...

Despite advances in treatment, children with acute lymphoblastic leukemia (ALL) still experience drug resistance and relapse. Several gene mutations are involved in the onset of this disease and resistance to therapy. The present study examines the incidence of IKZF1, CDKN2A/B, PAX5, EBF1, ETV6, BTG1, RB1, JAK2, and Xp22.33 gene deletions/duplications associated with pediatric ALL in Iran and investigates the possible effect of these mutations on drug resistance. Three-year disease-free survival (3DFS) was evaluated for children diagnosed with Philadelphia negative precursor-B-cell ALL hospitalized at Sayed-al-Shohada Hospital, Isfahan-Iran, from January 2009 until December 2012...

Annually, it is estimated that approximately 150-200 children aged 0-16 years are diagnosed with acute myeloid leukemia (AML). In Japan, clinical studies with ANLL91, AML99, CCLSG-AML9805, and JPLSG-AML05 protocols were performed historically, and the risk stratification with a combination of chemotherapy and hematopoietic stem cell transplantation resulted in the improvement of clinical outcomes. Regarding the onset of pediatric AML at the molecular level, mutations in FLT3-ITD or KIT (Class I mutation) showed a poor prognosis, but the ratio of mutations in Class III-V genes was smaller than that in adult AML...

Since adolescents and young adults (AYAs) with lymphoma began to be treated by pediatric hematologists and hematology physicians, few data have been collected regarding lymphoma in this generation of patients in Japan. We analyzed the number of pediatric hospitals that have treated hematological AYA patients. In half of the pediatric facilities, patients >15 years of age had been treated, and 40% of those facilities treated >1 AYA every year. A past lymphoma study by the Japanese Pediatric Leukemia/Lymphoma Study Group included some AYA patients...

Based on various studies, the survival of adolescent and young adults (AYAs) with acute myeloid leukemia (AML) was reportedly similar to or worse than younger children. AYAs with AML treated in adult institutions are usually offered the same treatment as that of the older adults. Although pediatric protocols generally include intensified regimens compared with adult protocols, it is still controversial whether an intensified pediatric AML regimen results in an improved survival for the AYA population. Somatic mutations have proven to be significantly prognostic in AML...

It is well known that adolescents and young adults (AYAs) with acute lymphoblastic leukemia (ALL) should be treated based on pediatric ALL protocol, which could yield better survival rates. However, an optimal treatment strategy for AYAs with acute myeloid leukemia (AML) is not yet established and corresponding data are limited. Compared with ALL, clinical and biological characteristics of pediatric and adult AML are relatively similar. Moreover, treatment strategy is quite similar, although pediatric protocols are more intensive and transplant indications are narrower...

Patients with acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYA) generation are treated by both pediatricians and adult hematologists. Because their participation rate in clinical trials has been low, the treatment results have been unsatisfactory. However, with a recent widespread adaptation of pediatric-based regimen in adult ALL trials, their prognosis has dramatically improved. Moreover, their characteristic biology is being rapidly elucidated. For further improvement of AYA-ALL prognosis and quality of life, the collaboration between pediatricians and adult hematologists is essential and multidisciplinary approach is necessary...
