PURPOSE Identifying among nephroblastoma those with a high propensity for distant metastases using cell cycle markers: cyclin E as a regulator of progression through the cell cycle and Ki-67 as a tumor proliferation marker, since both are often deregulated in many human malignancies. METHODOLOGY/PRINCIPAL FINDINGS A staining index (SI) was obtained by immunohistochemistry using anti-cyclin E ...

BRCA1-associated RING domain protein 1 (BARD1) is a tumor suppressor, which forms a heterodimer with BRCA1. Three BARD1 gene polymorphisms (rs7585356 G>A, rs6435862 T>G and rs3768716 A>G) were initially identified as high-risk neuroblastoma susceptibility loci by a previous GWAS. Because of the general tumor-suppressing function of BARD1, we hypothesized that these BARD1 gene polymorphisms migh...

Adult extrarenal nephroblastoma is a very rare tumor. Nephroblastoma arising from primary testicular germ cell tumor is exceedingly rare. To our knowledge, only three cases have been reported in the English literature. We report a case of a 19-year-old man who presented with a large right testicle. Image studies showed a large retroperitoneal mass along with liver and lung metastases. Orchiecto...

Histological classifications are essential for prognosis in children malignancies. Currently, the histological type of tumor is one of the main prognostic factors in this group. We investigated histoclinical features of nephroblastoma in relation to SIOP 93-01 and SIOP 2001 Classifications of Renal Tumors of Childhood. We examined all the routinely available histological features and histologic...

OBJECTIVE We examined expression of minichromosome maintenance 2 (MCM2) by immunohistochemistry in nephrectomy specimens of children with nephroblastoma treated according to the Society International d'Oncologie Pediatrique (SIOP) scheme to determine its potential prognostic significance. MATERIAL AND METHODS 18 children with nephroblastoma, 9 females and 9 males, 2 months to 7 years of age, ...

A nephroblastoma is a tumor arising from metanephric blastema occurring in childhood. Among laboratory rodents, nephroblastoma has been frequently reported in rats, but it remains exceedingly rare in mice. The present work describes a nephroblastoma in a young mouse homozygous for the specific Trp53 R172H point mutation coupled with targeted deletion of the Pin1 gene. The affected kidney was ef...

Background. Nephroblastoma is one of the most common childhood malignancies in Africa, but with a survival rate significantly lower than in developed countries. In African countries with a small gross domestic product (GDP) per capita, the cost of treating nephroblastoma may be prohibitive. Objectives. To determine the direct costs of treatment of nephroblastoma in South Africa (SA) and to prop...

CONTEXT Pancreatic metastasis from renal cell carcinoma is a well-known entity. When metastatic disease is limited to the pancreas, pancreatic resection is the optimal treatment. A nephroblastoma is a frequent childhood cancer but can also occur in adults. A metastatic nephroblastoma mainly affects the lung and the liver. Pancreatic metastases from a nephroblastoma are very rare. CASE REPORT ...

Cystic partially differentiated nephroblastoma is a rare tumor of the kidney usually affecting infants. It should be distinguished from Wilms’ tumor with multicystic areas and multilocular cystic nephroma. Multilocular cystic nephroma is a benign tumor whereas Wilms’ tumor with multicystic areas is at the malignant end of the range of classification of such tumours. Cystic partially differentia...
