: Wilms tumor (WT) is the most frequent renal of childhood and a highly responsive to chemotherapy. P53 ki67 are two important markers that have been evaluated in many cancers. The role p53 pathogenesis progression WT only partly understood. Over past decade, importance Ki-67

Neuroblastoma (NBL) is the most common extra-cranial tumour in childhood [1] and commonly presents as an abdominal mass. Nephroblastoma, also more commonly known as a Wilms’ tumour, is the commonest renal tumour in childhood and also typically presents as abdominal pathology. The natural histories and typical clinical courses of these tumours are very different, thus early distinction is import...

Purpose Wilms tumor is the commonest renal malignancy in childhood. Survival in high-income countries is approximately 90%, whereas in low-income countries, it is less than 50%. This study assessed treatment outcomes of patients with Wilms tumor at a Kenyan academic hospital. Patients and Methods We conducted a retrospective medical record review of all children diagnosed with Wilms tumor bet...

Basic fibroblast growth factor (bFGF) is a potent angiogenic peptide implicated in the growth and metastasis of solid tumors. Elevated concentrations of bFGF have been found in the urine of patients with bladder, prostate, and renal tumors. Furthermore, urinary bFGF levels have been shown to correlate with extent of disease. In order to test the utility of urinary bFGF as a Wilms' tumor marker,...

Wilms’ tumors is a renal malignancy commonly occurring in childhood with classic histopathological features. While the majority of the tumors present as renal masses, atypical presentations like extrarenal masses have also been known. However, the exact natural course of the disease and its outcome is not known. Here, we present two cases of extrarenal Wilms’ tumor, discuss the pathophysiology ...

The outcome of children with kidney tumors has significantly improved in the last two decades in the developed world but not in resource poor countries. We share our ten years experience from a single institution of Pakistan. Records of 23 children with kidney tumors were reviewed for demographics, presenting features, staging work-up and outcome. There were 21 (91%) children with Wilms tumor a...

Studies on the loss of heterozygosity (LOH) in human malignancies have shown that a number of different chromosomal regions associated with putative tumor suppressor genes may be involved in any one given tumor. We have carried out a similar study on Wilms' tumor using a range of DNA markers for a number of tumor suppressor regions. We tested a total of 44 Wilms' tumors including material from ...

A unique structural feature of the neural cell adhesion molecule N-CAM is the presence of homopolymers of alpha (2----8)-linked sialic acid units. We have used two specific probes for the detection of poly(sialic acid) in normal human kidney and Wilms tumor: a monoclonal antibody against meningococci group B capsular polysaccharide (homopolymers of alpha (2----8)-linked sialic acid units), whic...

Nearly 6000 patients enrolled in four clinical trials of the National Wilms' Tumor Study Group during 1969-1995 were followed until death or for a median of 11.0 years of survival for the onset of renal failure (RF). Thirteen of 22 patients with Denys-Drash syndrome and 10 of 46 patients with the Wilms' tumor aniridia syndrome developed RF. The cumulative risks of RF at 20 years from Wilms' tum...
