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...

background: neuroblastoma is the most common tumor in infancy and wilms’ tumor is the most common malignant tumor of kidney in childhood. both the tumors are usually within the differential diagnosis of each other. this study compares the clinical manifestations, sex and age distribution of childhood wilms’ tumor and neuroblastoma at one of tehran children hospitals. materials and methods: the ...

Wilms’ tumor is the most frequently occurring renal tumor in children and is one of the most treatment-responsive tumors. A tumor-suppressor gene and other genetic abnormalities have been implicated in its etiology. In addition, patients with several congenital anomalies, such as Beckwith-Wiedemann syndrome, WAGR syndrome, and DenysDrash syndrome, have an increased risk of Wilms’ tumor. Previou...

On the search for a genetic cause 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants found in 4th zinc finger (ZF4) of Wilms tumor 1 gene (WT1). Modelling these human granulosa cells and mice recapitulated phenotype.

Wilms' tumor is the most common childhood renal malignancy. A genome-wide association study identified LIM domain only 1 (LMO1) as having oncogenic potential. We examined the associations between LMO1 gene polymorphisms and susceptibility to Wilms' tumor. In this hospital-based, case-control study, we recruited 145 children with Wilms' tumor and 531 cancer-free children. Four polymorphisms (rs1...

PURPOSE Wilms' tumor is a childhood cancer of the kidney with an incidence of approximately 1 in 10,000. Cooccurrence of Wilms' tumor with 2q37 deletion syndrome, an uncommon constitutional chromosome abnormality, has been reported previously in three children. Given these are independently rare clinical entities, we hypothesized that 2q37 harbors a tumor suppressor gene important in Wilms' tum...

Wilms' tumor is one of the most common solid tumors of children. The protein product of the tumor-suppressor gene, Wilms' tumor 1 (WT-1), binds to the same DNA sequences as the protein product of the early growth response 1 (EGR-1) gene. There is experimental evidence that EGR-1 is involved in controlling cell growth. The expression of both genes in Wilms' tumor was studied by others, mainly at...

Wilms' tumor has served as an example of Knudson's two-hit hypothesis of recessive tumor genes, but the genetics has proven to be surprisingly complex. WT1, a tumor suppressor gene on 11p13, is mutated in only a small fraction of Wilms' tumors, and a second chromosomal region, 11p15, harbors a second Wilms' tumor gene also involved in other cancers. In addition, loss of genomic imprinting, or p...

The overall frequency of WT1 gene alterations in Wilms tumor is still unclear in Taiwan. Here we conducted molecular genetic analysis of the WT1 gene in Taiwanese patients with Wilms tumor. Polymerase chain reaction and direct sequencing were performed on DNA samples from blood and paraffin-embedded tumor specimens. A constitutional mutation in the WT1 gene was found in one DNA sample from peri...
