A new operative procedure in renal surgery has evolved from the extensive recent experience in kidney transplantation. Bench surgery and autotransplantation have not been, as yet, fully exploited by surgeons caring for children. This approach to reconstruction of renal substance and renal vessels has as its greatest dividend conservation of kidney tissue. The operation has specific applicabilit...
OBJECTIVE To provide guidelines for future trials, we reviewed the outcomes of children with synchronous bilateral Wilms tumors (BWT) treated on National Wilms Tumor Study-4 (NWTS-4). METHODS NWTS-4 enrolled 3335 patients including 188 patients with BWT (5.6%). Treatment and outcome data were collected. RESULTS Among 188 BWT patients registered with NWTS-4, 195 kidneys in 123 patients had i...
objectives this study aimed at reviewing the current literature on the diagnosis, staging, and different treatment strategies for wilms’ tumor with either ureteral or intravascular extension. evidence acquisition in this article, we reviewed the current literature about staging, diagnosis, and management strategies for wt, through a randomized clinical trial, which focused on this matter. the m...
Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with antev...
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. Using whole exome and gene-specific seque...
Five infants (two girls and three boys) from four families all had severe pre- and postnatal growth retardation, profound developmental delay, microcephaly, hypoplasia of the brain with Dandy-Walker complex or other posterior fossa malformations, and developed uncontrollable clonic seizures. Four infants developed Wilms tumors, and one showed cystic lesions in bilateral kidneys. All five infant...
Wilms' tumor, an embryonic renal neoplasm diagnosed primarily in young children, can occur in either a noninheritable (sporadic) or a familial form, with the latter presenting earlier and more often at bilateral sites. Although familial Wilms' tumor is thought to develop through inherited and acquired mutational inactivation of the two alleles of predisposing tumor suppressor genes, only a smal...
Wilms tumor (WT) is the most common cancer that primarily develops in abdominal solid organ of children. It has no incipient symptom, and the most frequent symptoms are a painless, palpable abdominal mass. Proteomics technology was used to select the differentially expressed proteins of bilateral Wilms tumor (BWT). Ten serum samples of children with BWT were chosen, 20 serum samples of children...
