Juvenile myelomonocytic leukemia is an aggressive myeloproliferative disorder characterized by malignant transformation in the hematopoietic stem cell compartment with proliferation of differentiated progeny. Seventy-five percent of patients harbor mutations in the NF1, NRAS, KRAS, or PTPN11 genes, which encode components of Ras signaling networks. Using single nucleotide polymorphism arrays, we identified a region of 11q isodisomy that contains the CBL gene in several JMML samples, and subsequently identified CBL mutations in 27 of 159 JMML samples. Thirteen of these mutations alter codon Y371. In this report, we also demonstrate that CBL and RAS/PTPN11 mutations were mutually exclusive in these patients. Moreover, the exclusivity of CBL mutations with respect to other Ras pathway-associated mutations indicates that CBL may have a role in deregulating this key pathway in

Results show that childhood cancer survivors, on average, have less psychological distress than a norm population but that the proportion of survivors at risk for high psychological distress is disproportionally large. Monitoring psychological distress in childhood cancer survivors may be desirable during routine follow-up, and psychological support should be offered as needed.

This article explores the grief process of parents following the death of a child due to a life-limiting illness, putting particular focus on dyadic coping. Participants included 46 married parents (23 couples). A mixed-methods design was used with in-depth interviews and standardized questionnaires. All parents were interviewed separately. Aspects of common dyadic coping (e.g., sharing emotions or maintaining bonds to the child) helped them work through their grief as a couple but also individually. The authors conclude that dyadic coping plays an important role in grief work and adjustment to bereavement.

We report on the outcome of children with advanced primary myelodysplastic syndrome (MDS) transplanted from an HLAmatched sibling (MSD) or an unrelated donor (UD) following a preparative regimen with busulfan, cyclophosphamide and melphalan. Ninety-seven patients with refractory anemia with excess blasts (RAEB, n ¼ 53), RAEB in transformation (RAEB-T, n ¼ 29) and myelodysplasia-related acute myeloid leukemia (MDR-AML, n ¼ 15) enrolled in the European Working Group of MDS in Childhood (EWOG-MDS) 98 study and given hematopoietic stem cell transplantation (HSCT) were analyzed. Median age at HSCT was 11.1 years (range 1.4-19.0). Thirty-nine children were transplanted from an MSD, whereas 58 were given the allograft from a UD (n ¼ 57) or alternative family donor (n ¼ 1). Stem cell source was bone marrow (n ¼ 69) or peripheral blood (n ¼ 28). With a median follow-up of 3.9 years (range 0.1-10.9), the 5-year probability of overall survival is 63%, while the 5-year cumulative incidence of transplantation-related mortality (TRM) and relapse is 21% each. Age at HSCT greater than 12 years, interval between diagnosis and HSCT longer than 4 months, and occurrence of acute or extensive chronic graft-versus-host disease were associated with increased TRM. The risk of relapse increased with more advanced disease. This study indicates that HSCT following a myeloablative preparative regimen offers a high probability of survival for children with advanced MDS.

BackgroundParents facing the death of their child have a strong need for compassionate professional support. Care services should be based on empirical evidence, be sensitive to the needs of the families concerned, take into account the heterogeneity within the medical field of paediatrics, and fit into the local health care system. We need to better understand the perspectives of parents facing the death of their child in order to guide further development and evaluation of specialised paediatric palliative and end-of-life (EOL) care services.MethodsQuestionnaire survey to assess the EOL care perspectives of a Swiss population-based sample of bereaved parents who had lost a child due to a cardiac, neurological or oncological condition, or during the neonatal period in the years 2011 or 2012. The parental perspective was assessed with a newly developed and tested instrument that was structured according to six evidence-based quality domains. Responses regarding parental experiences and perceived satisfaction are described. Differences between the four diagnostic groups are analysed using a generalized estimation equation to account for the dyadic data structure.ResultsOf 307 eligible families, 267 could be contacted and 135 (51 %) consented to participate in this questionnaire survey. Our findings show positive parental experiences of their child’s EOL care and high perceived satisfaction with the care their child received. Parents of a child with cancer rated their experiences highest in most of the six quality domains and reported the highest satisfaction with care. The lowest scores were mainly reported by parents from the neurology group, with the exception of the shared decision making domain, where parents of neonates reported significantly less positive experiences.ConclusionsAlthough positive in general, our study results suggest some areas for improvement. The integration of specialised paediatric palliative care has the potential to minimise lost opportunities to support and assist parents.Electronic supplementary materialThe online version of this article (doi:10.1186/s12904-016-0098-3) contains supplementary material, which is available to authorized users.

BACKGROUND:The objective of this study was to describe educational achievements of childhood cancer survivors in Switzerland compared with the general population. In particular, the authors investigated educational problems during childhood, final educational achievement in adulthood, and its predictors. METHODS: Childhood cancer survivors who were aged <16 years at diagnosis from 1976 to 2003 who had survived for !5 years and were currently ages 20 to 40 years received a postal questionnaire during 2007 to 2009. Controls were respondents of the Swiss Health Survey ages 20 to 40 years. Educational achievement included compulsory schooling, vocational training, upper secondary schooling, and university degree. The analysis was weighted to optimize comparability of the populations. The authors analyzed the association between demographic and clinical predictors and educational achievement using multivariable logistic regression. Subgroup analyses focused on survivors aged !27 years. RESULTS: One-third of survivors encountered educational problems during schooling (30% repeated 1 year, and 35% received supportive tutoring). In the total sample, more survivors than controls achieved compulsory schooling only (8.7% vs 5.2%) and fewer acquired a university degree (7.3% vs 11%), but more survivors than controls achieved an upper secondary education (36.1 vs 24.1%). In those aged !27 years, differences in compulsory schooling and university education largely disappeared. In survivors and controls, sex, nationality, language region, and migration background were strong predictors of achievement. Survivors of central nervous system tumors or those who had a relapse had poorer outcomes (P < .05). CONCLUSIONS: Childhood cancer survivors encountered problems during schooling and completed professional education with some delay. However, with the exception of patients who had central nervous system tumors and those who experienced a relapse, the final educational achievement in survivors of child cancer was comparable to that of the general population.

The majority of survivors did not report psychological distress. However, the severity of distress of distressed survivors exceeded that of distressed siblings and psychotherapy patients. Systematic psychological follow-up can help to identify survivors at risk and support them during the challenging period of adolescence.

BackgroundThe introduction of paediatric palliative care and referral to specialised teams still occurs late in the illness trajectory of children with life-limiting diseases. The aim of this ongoing multipart study was to develop a screening instrument for paediatricians that would improve the timely identification of children who could benefit from a palliative care approach.MethodsWe used a qualitative study approach with semi-structured interviews (Part 1) and a focus group discussion (Part 2) to define the domains and items of the screening instrument. Seven international paediatric palliative care experts from the UK, France, USA, and Canada took part in face-to-face interviews, and eleven paediatric health professionals from the University Children’s Hospital, Zurich, participated in a subsequent focus group discussion.ResultsThis preliminary phase of development and validation of the instrument revealed five domains relevant to identifying children with life-limiting diseases, who could benefit from palliative care: 1) trajectory of disease and impact on daily activities of the child; 2) expected outcome of disease-directed treatment and burden of treatment; 3) symptom and problem burden; 4) preferences of patient, parents or healthcare professional; and 5) estimated life expectancy. Where palliative care seems to be necessary, it would be introduced in a stepwise or graduated manner.ConclusionsThis study is a preliminary report of the development of an instrument to facilitate timely introduction of palliative care in the illness trajectory of a severely ill child. The instrument demonstrated early validity and was evaluated as being a valuable approach towards effective paediatric palliative care.
