Acute lymphoblastic leukemia (ALL) is the most common cancer in childhood. Standard chemotherapy has afforded outstanding outcomes for many patients; however, there remain some sub-groups with high-risk features, refractory disease, and patients that  relapse who have a poor prognosis with conventional treatments. Over the past decade, there have been significant advances in newer treatment options, including improved monoclonal antibody therapies, T cell engagers, and chimeric antigen T-cell receptor products, all of which have changed the landscape for patients who relapse...

Nowadays, the 5-year survival rate of childhood cancer patients can be more than 80%, but some patients with relapse and refractory cancers have shown no good response to traditional strategies. Chimeric antigen receptor engineered T (CAR-T) cell therapy is promising for these patients. CAR-T cells recognize the tumor-associated antigens in a non-major histocompatibility complex-restricted manner, so their anti-tumor ability is enhanced. There are four generations of CAR-T cells now. The complete remission rate of pediatric patients with relapse and refractory acute lymphoblastic leukemia can be as high as 90% when treated with CD19-targeting CAR-T cells...

Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is a subtype of B-lineage ALL (B-ALL) that displays a gene expression profile (GEP) similar to Philadelphia chromosome-positive ALL (Ph(+) ALL). It has a diverse range of genetic alterations that activate cytokine receptor genes and kinase signaling pathways, frequently accompanied by abnormal transcription factors related to lymphatic development. Children with Ph-like ALL account for 15% of children with high-risk B-ALL. It has adverse clinical features and a poor prognosis...

BACKGROUND: Several studies have reported a seasonal trend in the diagnosis of childhood cancer suggesting seasonal factors such as infection. The present study aimed to analyze the diagnosis pattern of childhood malignant diseases using public health data, and to compare this pattern with seasonal viral infection trends. METHOD: Using the open data source of the Health Insurance Review and Assessment Service, we extracted data regarding all patients under 21 years of age and who had any cancer, aplastic anemia or myelodysplastic syndrome between September 2009 and December 2013...

BACKGROUND: While cure rates for childhood acute lymphoblastic leukemia (cALL) now exceed 80%, over 60% of survivors will face treatment-related long-term sequelae, including cardiometabolic complications such as obesity, insulin resistance, dyslipidemia and hypertension. Although genetic susceptibility contributes to the development of these problems, there are very few studies that have so far addressed this issue in a cALL survivorship context. METHODS: In this study, we aimed at evaluating the associations between common and rare genetic variants and long-term cardiometabolic complications in survivors of cALL...

INTRODUCTION: The adolescent and young adult (AYA) age group (15-39 years) bears distinct characteristics in terms of cancer biology, long-term health and treatment-related complications and psychosocial aspects. The overall scenario of cancer including hematological malignancies (HMs) is largely unknown in Bangladesh, where a significant proportion of people (44% of total population) belong to AYA age group. This study aims to describe the patterns of HM among AYA in the context of Bangladesh METHODS: Two previously published datasets (on hematological malignancies and childhood and adolescent cancer) were merged to construct a comprehensive dataset focusing exclusively on HMs in AYA age group...

PURPOSE: Many childhood diseases often present with skin abnormalities with which radiologists are largely unfamiliar. Knowledge of associated dermatologic manifestations may aid the radiologist in confirming the diagnosis and recommending targeted imaging of affected organs. METHODS: We review the imaging findings in childhood diseases associated with dermatologic manifestations. FINDINGS: Diseases include dermatologic findings which herald underlying malignancy (Neuroblastoma, leukemia/lymphoma, Langerhans cell histiocytosis),are associated with risk of malignancy (Epidermolysis Bullosa, basal cell nevus syndrome, Cowden's syndrome, Tuberous Sclerosis),or indicate a systemic inflammatory/immune disorder (Kawasaki's disease, Henoch Schonlein Purpura, systemic lupus erythematosus, scleroderma, sarcoidosis, dermatomyositis and immune thrombocytopenic purpura)...

Background: Tumors of the central nervous system in the pediatric age group occur relatively frequently during the early years of life. Brain tumors are the most common solid malignancies of childhood and only second to acute childhood leukemia. Squash cytology is an indispensable diagnostic aid to central nervous system (CNS) lesions. The definitive diagnosis of brain lesions is confirmed by histological examination. Aim: To study the cytology of CNS lesions in pediatric population and correlate it with histopathology...

Childhood acute lymphoblastic leukemia (cALL) accounts for 25% of pediatric cancers and is one of the leading causes of disease-related death in children. Although long non-coding RNAs (lncRNAs) have been implicated in cALL etiology, progression, and treatment response, little is known about their exact functional role. We had previously sequenced the whole transcriptome of 56 cALL patients and identified lncRNA transcripts specifically silenced in tumoral cells. Here we investigated the impact of restoring the expression of three of these (RP11-624C23...

BACKGROUND: Children with Down syndrome (DS) are at increased risk of developing acute leukemia and are more prone to acute toxicities. We studied the incidence and severity of chronic health conditions among survivors of childhood leukemia with DS compared with those without DS. METHODS: Chronic health conditions reported by questionnaire were compared between 154 pediatric leukemia survivors with DS and 581 without DS, matched by leukemia, age at diagnosis, race/ethnicity, sex, radiation location and chemotherapy exposure using Cox models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs)...

BACKGROUND/AIM: Accumulated evidence has supported the notion that matrix metalloproteinase (MMP) genotypes are associated with the susceptibility of many types of cancers. However, few reports have studied the contribution of MMP genotypes to either diagnostic or prognostic potential in non-solid tumors such as leukemia. In this study, we firstly investigated the contribution of a polymorphism in the promoter region of MMP-8 (-799C/T) and two non-synonymous polymorphisms (Val436Ala and Lys460Thr) to childhood leukemia...

Iron is an intracellular element whose accumulation in the body is associated with tissue damage. This study examines the effect of iron on pediatric acute lymphoblastic leukemia (ALL) and its "response to treatment." At the end of the first year of treatment, bone marrow iron store (BMIS) was evaluated in children with ALL and the relationship between iron store and minimal residual disease was investigated. Moreover, the 3-year disease-free survival (3-DFS) of patients was determined. Patients' BMIS were compared with that of subjects with normal bone marrow...

PURPOSE OF REVIEW: Germline pathogenic TP53 mutation may predispose to multiple cancers but penetrance and cancer patterns remain incompletely documented. We have analyzed international agency for research on cancer TP53 database to reevaluate age and variant-dependent tumor patterns. RECENT FINDINGS: Genome-wide studies suggest that germline variants are more frequent than estimated prevalence of Li-Fraumeni syndrome (LFS), suggesting that many carriers of potentially pathogenic mutations may not develop the syndrome...

The tyrosine kinase inhibitor (TKI) imatinib was rationally designed to target BCR-ABL1 which is constitutively activated in chronic myeloid leukemia (CML). Following the tremendous success in adults, imatinib also became licensed for treatment of CML in minors. The rarity of pediatric CML hampers the conduction of formal trials. Thus, imatinib is still the single TKI approved for CML treatment in childhood. Areas covered: This review attempts to provide an overview of the literature on pharmacology, pharmacokinetic, and pharmacogenetic of imatinib concerning pediatric CML treatment...

Acute lymphoblastic leukemia is one of the malignant proliferations of lymphoid cells in the early stages of differentiation and accounts for about 80% of all cases of childhood leukemia. Side effects of available treatment are still main concern. Thymoquinone (TQ), a natural compound isolated from Nigella sativa, induces growth inhibition and apoptosis in several cancer cell lines. The aim of the present study was to investigate the effect of TQ alone and in combination with doxorubicine on the proliferation inhibition and apoptosis induction of TQ in a lymphoblastic leukemia cell line...
