Strategies to improve the quality of survival for childhood brain tumour survivors
Abstract Background Tumours of the central nervous system (CNS) are the most frequent solid tumours and the second most frequent type of cancer in children and adolescents. Overall survival has continuously improved in Germany, since an increasing number of patients have been treated according to standardised, multicentre, multimodal treatment recommendations, trials of the German Paediatric Brain Tumour Consortium (HIT-Network) or the International Society of Paediatric Oncology-Europe (SIOP-E) during the last decades. Today, two out of three patients survive. At least 8000 long-term childhood brain tumour survivors (CBTS) are currently living in Germany. They face lifelong disease- and tr…
Frequency, Risk-Factors and Survival of Children With Atypical Teratoid Rhabdoid Tumors (AT/RT) of the CNS Diagnosed between 1988 and 2004, and Registered to the German HIT Database
Purpose To analyze the frequency, prognostic factors, and outcome of children with atypical teratoid/rhabdoid tumors (AT/RT), a rare and highly malignant embryonal brain tumor. Materials and Methods Clinical data of patients diagnosed between 1988 and 2004 with AT/RT who were registered to the German HIT trial center, were correlated with outcome. Patient numbers for AT/RT were compared to numbers for primitive neuroectodermal tumors and medulloblastomas (PNET/MB) registered to the population-based HIT trials. Results We identified 56 patients with the centrally confirmed histopathological diagnosis of AT/RT with a median age of 1.2 years (range, 0.1–14.0 years). The AT/RT:PNET/MB ratio was…
Childhood cancer predisposition syndromes-A concise review and recommendations by the Cancer Predisposition Working Group of the Society for Pediatric Oncology and Hematology.
Heritable predisposition is an important cause of cancer in children and adolescents. Although a large number of cancer predisposition genes and their associated syndromes and malignancies have already been described, it appears likely that there are more pediatric cancer patients in whom heritable cancer predisposition syndromes have yet to be recognized. In a consensus meeting in the beginning of 2016, we convened experts in Human Genetics and Pediatric Hematology/Oncology to review the available data, to categorize the large amount of information, and to develop recommendations regarding when a cancer predisposition syndrome should be suspected in a young oncology patient. This review su…
Clinical and genetic risk factors define two risk groups of extracranial malignant rhabdoid tumours (eMRT/RTK)
Abstract Introduction Extracranial rhabdoid tumours are rare, highly aggressive malignancies primarily affecting young children. The EU-RHAB registry was initiated in 2009 to prospectively collect data of rhabdoid tumour patients treated according to the EU-RHAB therapeutic framework. Methods We evaluated 100 patients recruited within EU-RHAB (2009–2018). Tumours and matching blood samples were examined for SMARCB1 mutations by sequencing and cytogenetics. Results A total of 70 patients presented with extracranial, extrarenal tumours (eMRT) and 30 with renal rhabdoid tumours (RTK). Nine patients demonstrated synchronous tumours. Distant metastases at diagnosis (M+) were present in 35% (35/1…
Tumors of the central nervous system in children and adolescents.
Multimodal treatment approaches for children with tumors of the central nervous system (CNS) have markedly contributed to improved survival. Before 1970, the survival rate among children with medulloblastoma, the most common malignant CNS tumor in children, was about 20%. At present, in contrast, cure can be achieved in more than 75% of children with a favorable constellation of risk factors. In this review article for clinicians, we give an overview of the current understanding of the pathology, presenting manifestations, early diagnosis, and treatment of CNS tumors in children and adolescents.We report the research findings of the German Treatment Network "HIT" and selectively review the …
