Abstract
Children with Down syndrome constitute a distinct genetic population who has a greater risk of developing acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) compared to their non-Down syndrome counterparts. The risk for developing solid tumors is also distinct from the non-Down syndrome population. In the case of myeloid leukemias, the process of leukemogenesis in Trisomy 21 begins in early fetal life where genetic drivers including GATA1 mutations lead to the development of the preleukemic condition, transient abnormal myelopoiesis (TAM). Various other mutations in genes encoding cohesin, epigenetic regulators and RAS pathway can result in subsequent progression to Myeloid Leukemia associated with Down Syndrome (ML-DS). The striking paradoxical feature in the Down syndrome population is that even though there is a higher predisposition to developing AML, they are also very sensitive to chemotherapy agents, particularly cytarabine, thus accounting for the very high cure rates for ML-DS compared to AML in children without Down syndrome. Current clinical trials for ML-DS attempt to balance effective curative therapies while trying to reduce treatment-associated toxicities including infections by de-intensifying chemotherapy doses, if possible. The small proportion of patients with relapsed ML-DS have an extremely poor prognosis and require the development of new therapies.

Abstract
CONTEXT Owing to life expectancy improvements for people with intellectual disabilities, their risk of developing cancer is increasing. Pain is an inevitable aspect of cancerous diseases. However, as pain experience and expression can be atypical in people with intellectual disabilities, this population is vulnerable to late diagnosis of cancer and undertreatment of cancer pain. OBJECTIVES The objective of this study was to investigate what is currently known about cancer pain in people with intellectual disabilities and provide specific recommendations to improve this knowledge. METHODS A systematic review using PubMed, PsycINFO, and CINAHL and an anonymous online survey of Dutch health care professionals were conducted. RESULTS From 10,146 publications, with intellectual disabilities in the title, and pain or cancer in the title or abstract, 11 articles underwent qualitative synthesis. Discussions within these articles were predominantly unspecific and brief, frequently indicating challenges in symptom presentation, communication, as well as assessment and treatment of cancer pain. The survey received 102 responses. The 63 health care professionals experienced with cancer in people with intellectual disabilities indicated challenges recognizing, assessing, and treating their cancer pain. CONCLUSION Cancer pain in people with intellectual disabilities is a topic lacking specific and comprehensive research within scientific literature. We suggest this is due to inherent difficulties regarding the complex interplay of comorbidities and communication issues in people with intellectual disabilities.

Abstract
Children with Down syndrome have a 150-fold increased risk of developing acute myeloid leukemia (AML) and 20-fold increased risk of developing acute lymphoblastic leukemia (ALL). Although the risk of developing AML and ALL is significantly increased in children with Down syndrome, the development of both malignancies in the same patient is very rare. We describe a patient with Down syndrome who developed ALL 6 years after being diagnosed with AML. We performed a literature review and Children's Oncology Group query and discovered eight published cases and five cases of ALL following AML in pediatric patients with Down syndrome, as well as six cases of ALL following AML in non-Down syndrome patients. There was a similar cumulative incidence of ALL after treatment for AML in the Down syndrome and non-Down syndrome populations. Overall survival in patients with Down syndrome who developed ALL after treatment for AML was comparable to overall survival for patients with Down syndrome with de novo ALL with an average follow-up of 7 years after ALL diagnosis. Clinical data collected were used to discuss whether this phenomenon represents a secondary leukemia, second primary cancer, or mixed-lineage leukemia.

Abstract
Patients with Down syndrome (DS) are predisposed to acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) in early and later childhood, respectively, but rarely experience both. We herein discuss four patients with DS with ALL and a history of AML who were treated with various chemotherapies, one of whom later received a bone marrow transplantation. Three patients survived and remain in remission. One patient died of fulminant hepatitis during therapy. No common cytogenetic abnormalities in AML and ALL besides constitutional +21 were identified, indicating that the two leukemia types were independent events. However, the underlying pathomechanism of these conditions awaits clarification.

Curr Genomics 2011; 11:409-19.

Abstract
It is well known that varying degrees of mosaicism for Trisomy 21, primarily a combination of normal and Trisomy 21 cells within individual tissues, may exist in the human population. This involves both Trisomy 21 mosaicism occurring in the germ line and Trisomy 21 mosaicism documented in different somatic tissues, or indeed a combination of both in the same subjects. Information on the incidence of Trisomy 21 mosaicism in different tissue samples from people with clinical features of Down syndrome as well as in the general population is, however, still limited. One of the main reasons for this lack of detailed knowledge is the technological problem of its identification, where in particular low grade/cryptic Trisomy 21 mosaicism, i.e. occurring in less than 3-5% of the respective tissues, can only be ascertained by fluorescence in situ hybridization (FISH) methods on large cell populations from the different tissue samples.In this review we summarize current knowledge in this field with special reference to the question on the likely incidence of germinal and somatic Trisomy 21 mosaicism in the general population and its mechanisms of origin. We also highlight the reproductive and clinical implications of this type of aneuploidy mosaicism for individual carriers. We conclude that the risk of begetting a child with Trisomy 21 Down syndrome most likely is related to the incidence of Trisomy 21 cells in the germ line of any carrier parent. The clinical implications for individual carriers may likewise be dependent on the incidence of Trisomy 21 in the relevant somatic tissues. Remarkably, for example, there are indications that Trisomy 21 mosaicism will predispose carriers to conditions such as childhood leukemia and Alzheimer's Disease but there is on the other hand a possibility that the risk of solid cancers may be substantially reduced.

Abstract
PURPOSE OF REVIEW Myelodysplastic and myeloproliferative disorders are clonal myeloid malignancies characterized by the triad of a growth advantage of clonal cells, disturbed differentiation and increased apoptosis. The rarity of these disorders in children and the lack of a widely accepted classification have contributed to the paucity of reports on these malignancies in the pediatric literature. A number of significant advances have been achieved in recent years. The present review will focus on diagnostics and therapy. RECENT FINDINGS International consensus has been achieved on classifying these disorders into three main groups; myelodysplastic syndrome (MDS), myeloid leukemia of Down syndrome (ML-DS) and juvenile myelomonocytic leukemia (JMML). In the last few years we have witnessed important advances, especially regarding the therapy of these disorders, and we have gained insights into the molecular pathogenesis of ML-DS and JMML. SUMMARY Classification of myelodysplastic and myeloproliferative disorders has been facilitated. Chemotherapy regimens for ML-DS have been reduced, resulting in fewer toxic deaths and improved survival. The results of stem-cell transplantation for MDS and JMML have improved. Insight into the molecular mechanisms involved may open new therapeutic avenues.

Abstract
Acute lymphoblastic leukaemia in children with Down syndrome (ALL-DS) is characterised by unique clinical and biological features. Notable among these are an absence of ALL in DS patients <1 year of age; a lower incidence of favourable and unfavourable chromosomal translocations; heightened sensitivity to methotrexate; and an increased propensity to infections. Although children with ALL-DS have historically fared less well than their non-DS counterparts (ALL-NDS), recent data indicate that outcomes in ALL-DS are now comparable with ALL-NDS with risk-adapted therapies, after adjusting for biological differences between the ALL-DS and ALL-NDS populations. Given the increased risk of ALL-DS patients for treatment-related toxicities, further intensification of therapy may not yield continued improvements in survival. Future investigations in the ALL-DS population should focus on maintaining excellent outcomes while reducing treatment-related complications through novel treatment strategies, such as the integration of targeted noncytotoxic agents.

Abstract
Transient myeloproliferative disorder (TMD) is found in 10% of newborns with Down syndrome (DS). Myeloid leukemia develops in 25% within the following 3 years. Little is known about markers predicting leukemia occurrence. We studied expression levels of the Wilms tumor gene (WT1) by real-time quantitative PCR (RQ-PCR) in peripheral blood of five infants with TMD. WT1 levels were elevated similar to findings in AML. Longitudinal studies showed normalization of the WT1 level in all patients except one who developed GATA1 mutated myeloid leukemia at 11 months of age. The lack of normalization of WT1 level may be a predictor of leukemia development and WT1 expression may be an attractive marker for monitoring of minimal residual disease.
