Blastemal histology in chemotherapy-treated pediatric Wilms tumors (nephroblastoma) is associated with adverse prognosis. To uncover the underlying tumor biology and find therapeutic leads for this subgroup, we analyzed 58 blastemal type Wilms tumors by exome and transcriptome sequencing and validated our findings in a large replication cohort. Recurrent(More)
Current treatment protocols for Wilms tumor achieve 90% cure rates, but relapse risk and side effects from therapy remain challenging. Over the last decade, numerous markers have been proposed for classification and/or prediction of outcome. However, cohort sizes were quite variable and often small. We now provide a large-scale reassessment by real-time(More)
Genomic gain of the proto-oncogene transcription factor gene MYCN is associated with poor prognosis in several childhood cancers. Here we present a comprehensive copy number analysis of MYCN in Wilms tumour (WT), demonstrating that gain of this gene is associated with anaplasia and with poorer relapse-free and overall survival, independent of histology.(More)
Functional analysis of gene candidates and testing of novel therapeutics in Wilms tumors (WT) has been hampered by the lack of in vitro model systems. WT are characterized by a spectrum of histological appearances, but published cell lines are mostly derived from rare anaplastic variants or even non-WT. There has been some success in establishing primary(More)

PURPOSE Wilms' tumor is a childhood cancer of the kidney with an incidence of approximately 1 in 10,000. Cooccurrence of Wilms' tumor with 2q37 deletion syndrome, an uncommon constitutional chromosome abnormality, has been reported previously in three children. Given these are independently rare clinical entities, we hypothesized that 2q37 harbors a tumor(More)
Cardiovascular diseases are the major cause of human death and have been linked to many different risk factors. Among them, coxsackievirus B3 (CVB3), as a member of the enterovirus group, is one of the most important infectious agents of virus-induced myocarditis. Despite the fact that the molecular structure of this pathogen has been characterized very(More)
Wilms tumor (WT) is one of the most common solid tumors in childhood. Mutations in WT1 and CTNNB1 are well established as causal alterations in about 10-15% of cases. Recently, WTX (WT gene on the X-chromosome), a gene implicated in WNT signaling, has been identified as a third WT gene. We determined the mutation status of WTX, CTNNB1, and WT1 in a large(More)
Wilms tumor (WT) is one of the most common malignancies in childhood. With current therapy protocols up to 90% of patients can be cured, but there is still a need to improve therapy for patients with aggressive WT and to reduce treatment intensity where possible. Prior data suggested a deregulation of the retinoic acid (RA) signaling pathway in high-risk(More)
PURPOSE Wilms' tumor (WT), the most common pediatric renal malignancy, is associated with mutations in several well-characterized genes, most notably WT1, CTNNB1, WTX, and TP53. However, the majority of cases do not harbor mutations in these genes. We hypothesized that additional drivers of tumor behavior would be contained within areas of consistent(More)
PURPOSE Wilms tumor (WT) is the most common pediatric renal tumor. Treatment planning under International Society of Paediatric Oncology (SIOP) protocols is based on staging and histologic assessment of response to preoperative chemotherapy. Despite high overall survival (OS), many relapses occur in patients without specific risk factors, and many(More)
