The purpose of this work is to assess the clinical outcome pediatric patients diagnosed with pheochromocytoma and paraganglioma (PPGL) detected in France since 2000.A retrospective multicenter study was conducted that included all younger than 18 years PPGL between 2000 2016. Patients were identified from 4 different sources: National Registry Childhood Solid Tumors, French Pediatric Rare Tumors Database, registry succinate dehydrogenase (SDH)-related hereditary paraganglioma, nationwide...

Survival after childhood acute lymphoblastic leukemia (ALL) has increased over the last 40 years with an overall survival above 90%. Survivors may experience neurological late effects secondary to chemotherapy and radiotherapy. This observational retrospective study evaluated cumulative incidence of among 890 ALL survivors treated in EORTC CLG trials (58741, 58831/2 58881) between 1971 1998. Median follow-up was 19 interquartile range 15-22 years. At 20 from end treatment, approximately 66%...

Some previous epidemiological studies have suggested that pesticide exposure during pregnancy may a possible role in the development of childhood brain tumors (CBT). We pooled data from two French national population‐based, case–control to investigate association between maternal residential use pesticides and risk CBT. The mothers 437 CBT cases 3,102 controls aged under 15 years who resided France at diagnosis/interview, frequency‐matched by age gender, answered structured telephone...

The aims this study were to investigate whether extremes birth weight associated with increased risk CBT and maternal preconceptional folic acid supplementation or breastfeeding reduced risk. In addition, other characteristics related factors also investigated. We pooled data from two French national population-based case-control studies similar designs conducted in 2003-2004 2010-2011. mothers 510 cases (directly recruited cancer...

Improved treatment landscape has led to better outcomes for paediatric acute lymphoblastic leukemia (ALL) survivors. As the number of survivors increase, we need elucidate long-term quality life (QoL) and domains complaints in these patients. Furthermore, main priorities patients be clarified. We assessed QoL childhood ALL compared matched population controls.QoL data were collected from recruited France Belgium between 2012 2017, including Short Form Health Survey (SF-12) Quality Life...
