BACKGROUND Childhood renal cell carcinomas (RCCs) differ histologically and biologically from their adult counterparts. The characteristics of RCC-affected children and their tumors, the influence of treatment, and outcome have so far not been studied in a nonselected, population-based cohort. METHODS A retrospective analysis was undertaken of RCC(More)
BACKGROUND Mesenchymal chondrosarcoma (MCS) is a rare tumor with a strong tendency toward late recurrences leading to reported 10-year survival rates below 50%. The recommended treatment is resection with wide margins; the effectiveness of chemo- and radiotherapy remain poorly defined. As reports about MCS in young patients are scarce, treatment and(More)
Clear cell sarcoma of the kidney (CCSK) is a rare renal tumour that is observed most often in children under 3years of age. Only a few large series of CCSK have been reported and patients with CCSK are often included among patients with other types of childhood renal tumours. The purpose of this paper is to review the published series and case reports of(More)
BACKGROUND Surgery alone is the appropriate first-line treatment for patients with mesoblastic nephroma (MN). Nevertheless, there are reports of local recurrences and metastasis, especially in the cellular subtype. The authors evaluated the outcome of patients with MN who were enrolled in either the International Society of Pediatric Oncology (SIOP)(More)
BACKGROUND More than 80% of all paediatric oncology patients have a long term central -catheter (CVAD; port or Broviac type). Many aspects considering the use of CVADs have not been studied. PATIENTS Children and adolescents treated in Paediatric Oncology centres. METHODEN Internet-based multicentre survey related to the use of CVADs conducted in(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)
PURPOSE A reference radiologic diagnosis was carried out for the purpose of quality control and in order to achieve high diagnostic accuracy in the ongoing trial and study SIOP 2001/GPOH for renal tumors during childhood. The aim of the present study is to evaluate the value of diagnostic imaging and the benefit of reference evaluation at a pediatric(More)
OBJECTIVE To assess surgical aspects in the treatment of children with unilateral Wilms tumor based on data from the Cooperative Tumor Study SIOP 93-01 of the German Society of Pediatric Hematology and Oncology. SUMMARY BACKGROUND DATA Although multiple international study trials exist for the treatment of nephroblastoma, the impact of surgical details(More)
BACKGROUND Preventive approaches (including those related to care of long term central venous catheters, CVADs) and the incidence of bloodstream infections (BSI) in 2 German university affiliated paediatric oncology units. PATIENTS AND METHODS Non-interventional prospective observational study using the Oncoped surveillance module. Center A included 85(More)
PURPOSE To differentiate classic and cellular type of congenital mesoblastic nephroma (CMN) in MRI and to evaluate MRI for staging according to the Societe Internationale de Oncologie Pediatrique (SIOP). MATERIAL AND METHODS MRI examinations of 20 children with CMN (age 1st to 16th months, classic type n = 11, cellular type n = 7, mixed type n = 2) were(More)
