In the past, increases in childhood cancer incidence were reported in Europe and North America. The aim of this study is to show updated patterns of temporal behavior using data of the Childhood Cancer Registry of Piedmont (CCRP), a region with approximately 4.5 million inhabitants in North-West Italy. CCRP has been recording incident cases in children (0-14 years) since 1967 and in adolescents (15-19) since 2000. Time trends were estimated as annual percent change (APC) over the 1976-2011 period for children, and over 2000-2011 for both children and adolescents...

PURPOSE: To compare the effect of 12 versus 18 Gy cranial radiation therapy (RT) on height and weight indices among pediatric patients with acute lymphoblastic leukemia (ALL). METHODS AND MATERIALS: Records of children with ALL who were 2 to 14 years old at the time of RT and were treated at a single institution between 2000 and 2011 were reviewed. Patients' height, weight, and body mass index were converted into z-scores using the Centers for Disease Control growth charts to normalize the values to number of standard deviations from the mean...

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is an ultrarare genetic disorder of progressive, disabling heterotopic ossification (HO) for which there is presently no definitive treatment. Research studies have identified multiple potential targets for therapy in FOP, and novel drug candidates are being developed for testing in clinical trials. A complementary approach seeks to identify approved drugs that could be re-purposed for off-label use against defined targets in FOP...

Height at diagnosis has been analyzed in connection with acute lymphoblastic leukemia (ALL). Most prior studies have compared cases to national reference data derived from previous birth cohorts. Our objective was to determine the association of height-for-age Z score (HAZ) at time of diagnosis with the odds ratio (OR) of ALL in a case-control study (N=498) with a contemporaneous population of age-matched, sex-matched, and ethnicity-matched controls. We hypothesized that cases would have greater mean HAZ at time of diagnosis/interview, after adjustment for weight-for-age (WAZ) and weight-for-height (WHZ)...

In the literature, studies on the oxidant effects of nontransferrin bound iron [NTBI (eLPI assay)] during chemotherapy of acute lymphoblastic leukemia and acute myeloblastic leukemia are lacking. We established NTBI and oxidative stress determinants (OSD), iron parameters, high-sensitive C-reactive protein (hs-CRP) levels, liver tests, cumulative chemotherapeutic doses, and transfused blood in 36 children with acute leukemia throughout chemotherapy. These parameters were determined at the beginning and end of chemotherapy blocks (11 time points) and in 20 healthy children using enzyme-linked immunosorbent assay, and colorimetric and fluorometric enzymatic methods...

Invasive fungal infections are rare in children with acute lymphoblastic leukemia. It compromises the antileukemia therapy should it happen. Central nervous system fungal infections carry high mortality. We here report the case of a 6.5-year-old girl who developed multiple central nervous system fungal abscesses possibly due to Aspergillus infection during induction therapy for acute lymphoblastic leukemia who has been successfully managed without compromising antileukemia therapy. She has been receiving antifungal therapy and maintenance chemotherapy for 20 months from diagnosis...

Src homology 2 domain-containing protein tyrosine phosphatase 2 (SHP-2) is a cytoplasmic tyrosine phosphatase that is highly expressed in hematopoietic cells and in the CNS and exerts opposite effects on signal transduction by exerting a neuroprotective or proapoptotic effect. Several mutations of SHP-2 have been found in children with myeloproliferative disorders or malignant leukemia, and some of these can affect brain development. In the present study, we aimed to identify and functionally characterize genetic variations in SHP-2 in 72 preterm and 58 full-term infants and to evaluate the effect of the variations on neurodevelopment in preterm infants...

As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls...

Black patients have a twofold increased risk of induction mortality compared to White patients with acute myeloid leukemia (AML). We reviewed diagnosis and billing data from Pediatric Health Information System for 28 AML Induction I deaths to investigate conditions preceding death in White and Black patients. Half of deaths occurred within 10 days of initial diagnostic admission. Respiratory, cardiac, renal, and infectious complications were common prior to both White and Black deaths. Deaths in White patients were more commonly preceded by intracranial hemorrhage compared to deaths in Black patients...

Vincristine (VNC) is commonly used to treat pediatric cancers, including the most prevalent childhood malignancy, acute lymphoblastic leukemia. Although clinical evidence suggests that VNC causes peripheral neuropathy in children, the degree to which pediatric chemotherapeutic regimens influence pain sensitivity throughout life remains unclear, in part because of the lack of an established animal model of chemotherapy-induced neuropathic pain during early life. Therefore, this study investigated the effects of VNC exposure between postnatal days (P) 11 and 21 on mechanical and thermal pain sensitivity in the developing rat...

Cancer patients and their caregivers are increasingly using social media as a platform to share cancer experiences, connect with support, and exchange cancer-related information. Yet, little is known about the nature and scientific accuracy of cancer-related information exchanged on social media. We conducted a content analysis of 12 months of data from 18 publically available Facebook Pages hosted by parents of children with acute lymphoblastic leukemia (N = 15,852 posts) and extracted all exchanges of medically-oriented cancer information...

We have aimed to determine the effect of polymorphisms in regulatory regions of the DHFR gene in relation to methotrexate (MTX) dose adjustments and drug-induced toxicity in children on maintenance therapy for acute lymphoblastic leukemia (ALL). In total, 41 children diagnosed with ALL were screened for 3 tag-single nucleotide polymorphisms in the DHFR promoter (C-1610G, C-680G/T, A-317G) and an intronic 19-bp insertion/deletion. Genotypes were analyzed in relation to dose requirements and toxicity. The percentage of MTX dose administered (with respect to protocol-recommended values) was affected by DHFR polymorphisms...

Until recently hematopoietic stem cell transplantation was the only curative option for Wiskott-Aldrich syndrome (WAS). The first attempts at gene therapy for WAS using a ϒ-retroviral vector improved immunological parameters substantially but were complicated by acute leukemia as a result of insertional mutagenesis in a high proportion of patients. More recently treatment of children with a state-of-the-art self-inactivating lentiviral vector (LV-w1.6 WASp) has resulted in significant clinical benefit without inducing selection of clones harbouring integrations near oncogenes...

BACKGROUND: Although the proportion of Pseudomonas aeruginosa infections has reduced after the introduction of antibiotics with anti-pseudomonal effects, P. aeruginosa bacteremia still causes high mortality in immunocompromised patients. This study determined the clinical characteristics and outcomes of P. aeruginosa bacteremia and the antibiotic susceptibilities of strains isolated from febrile neutropenic patients. METHODS: Thirty-one febrile neutropenic children and adolescents with underlying hematologic/oncologic disorders diagnosed with P...

BACKGROUND: Though the association between parental age at child's birth and the risk of childhood cancer has been previously investigated, the evidence to date is inconclusive and scarce for rarer cancer types. METHODS: Cancer cases (N=5,856) were selected from all children born from 1968 to 2014 and diagnosed from 1968 to 2015 in Denmark at less than 16 years of age listed in the nationwide Danish Cancer Registry. Cases were individually matched to controls (1:100) on sex and year of birth with a total of 585,594 controls randomly sampled from all live births in Denmark from the Danish Central Population Registry...

The aim of the present work was to assess whether polymorphisms in genes coding for drug transport proteins may influence dosing, efficacy and toxicity of maintenance therapy with methotrexate (MTX) and 6-mercaptopurine (6MP) in childhood acute lymphoblastic leukemia (ALL). A total of 41 children with ALL were screened for 10 SNPs in the SLC19A1, ABCB1, ABCC2, ABCC4 and ABCG2 transporter genes by means of direct sequencing. Carriers of the ABCC4 934CC and ABCB1 1236TT genotypes received a lower percentage of the protocol-recommended starting dose of MTX (62...

Chimeric transcription factor E2A-PBX1 induces the development of acute lymphoblastic B-cell leukemia in children. Using a transgenic mouse model, we previously demonstrated that homeobox (HOX) gene HOXA9 genetically interact with E2A-PBX1 gene in the development of B-cell leukemia in mice. HOXA9 itself is a potent oncogene resulting in myeloid leukemia when overexpressed, which is strongly accelerated by its collaborator Meis1. HOX, PBX1 and MEIS1 proteins have been shown to form hetero dimeric or trimeric complexes in different combinations...
