All patients received protocols for STS: Cooperative(More)
Glomerular filtration rate (GFR) was evaluated in 32 Wilms' tumour survivors (WTs) in a cross-sectional study using 99 Tc-diethylene triamine pentaacetic acid (99 Tc-DTPA) clearance, the Schwartz formula, the new Schwartz equation for chronic kidney disease (CKD), cystatin C serum concentration and the Filler formula. Kidney damage was established by(More)
The lack of registration of ultrasound contrast agents for use in patients below the age of 18 is a significant limitation of their usage. Despite this, examinations with the use of contrast agents are conducted in numerous centers, mainly as part of the diagnostic process of vesicoureteral reflux. Examinations after an intravenous administration of(More)

MYCN oncogene amplification is the most important prognostic factor in neuroblastoma. 25% neuroblastoma tumors have somatic amplifications at this locus but little is known about its constitutional aberrations and their potential role in carcinogenesis. Here, we have performed an array-CGH and qPCR characterization of two patients with constitutional(More)
AIM OF THE STUDY Recent studies showed relatively better outcome for children with refractory (refAML) and relapsed acute myeloid leukemia (relAML). Treatment of these patients has not been unified within Polish Pediatric Leukemia/Lymphoma Study Group (PPLLSG) so far. The goal of this study is to analyze the results of this therapy performed between(More)
