Purpose: Wilms' tumor is a childhood cancer of the kidney with an incidence of ∼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' tumor pathogene...
BACKGROUND Denys-Drash syndrome (DDS) is associated with mutations of the Wilms' tumour 1 (WT1) gene, and is characterized by pseudohermaphroditism, a progressive glomerulopathy, and the development of Wilms' tumour. More than 90% of patients with DDS who carry constitutional intragenic WT1 mutations are at high risk (90%) for the development of Wilms' tumour. WT1 is a signalling protein with 9...
We have previously demonstrated an increased DNA copy number and expression of IGF1R to be associated with poor outcome in Wilms tumors. We have now tested whether inhibiting this receptor may be a useful therapeutic strategy by using a panel of Wilms tumor cell lines. Both genetic and pharmacological targeting resulted in inhibition of downstream signaling through PI3 and MAP kinases, G(1) cel...
Wilms' tumor is one of the most prevalent pediatric malignancies, ranking fourth in childhood cancer worldwide. TP53 is a critical tumor suppressor gene, which encodes a 53 kDa protein, p53. The p53 functions to protect against cancer by regulating cell cycle and apoptosis and maintaining DNA integrity. TP53 gene is highly polymorphic. Several TP53 gene polymorphisms have been considered to be ...
The incidence of renal dysplasia in a series of Wilms' tumours is presented. The distribution of such lesions is discussed, together with their course of development and regression. The kidney is regarded as a particularly suitable organ for studying the relation between dysplasia and neoplasia. A schema is suggested for this association with regard to Wilms' tumour.
Wilms tumor, or nephroblastoma, is the most common malignant tumor of the urinary tract in children, but is rarely found in adults. Here, we report the first case of a female patient with a Wilms tumor, diagnosed during pregnancy, who underwent radical nephrectomy and adjuvant chemotherapy before and after delivering a healthy child. Generally, treatment should follow the guidelines established...
Fungal infections are increasingly being reported in immuno-compromised patients. In this study we report a case of systemic Trichosporon cutaneum infection in an infant with Wilms' tumor. This is the first time that an invasive infection for T. cutaneum has been reported in a Wilms' tumor patient.
A 64-year-old man underwent left radical nephrectomy for stage III anaplastic Wilms’ tumor. He received adjuvant chemotherapy consisting of cisplatin and etoposide. Complete clinical response was achieved and maintained for 12 months. A systemic relapse after 1 year also responded to three more cycles of cisplatin and etoposide. Although cisplatinand etoposide-based chemotherapy was not used as...
