Background : Wilms' tumor (nephroblastoma) is the most common renal malignancy of childhood. This cancer is considered as an embryonal neoplasm that arises from nephrogenic blastemal. Despite advances in therapeutic success, survival rate is still not satisfactory in tumors with unfavorable histology and recurrent cases. On the other hand, late adverse effects of chemotherapy threaten the lif...
Comparatively few cases of bilateral Wilms' tumour have been described in the past 55 years. In 1897, Walker reviewed the literature over the previous 100 years and found 141 cases of Wilms' tumour of which 10 were said to be bilateral, but he gave no details of these. Hedren (1907) described a remarkable case with apparent multicentric origin in both kidneys. In 1931, Kretschmer and Hibbs foun...
Other names: Nephroblastoma Note: Wilms' tumor, although generally rare, is the most common abdominal malignancy in children. Wilms' tumor cells are believed to derive from pluripotent embyronic renal precursor cells. Thus, Wilms' tumors are linked to the early development of the kidney. While most are isolated sporadic tumors, approximately 10% of cases are associated with genetic syndromes an...
The main primary childhood renal neo-plasms are nephroblastoma, mesoblastic ne-phroma, clear cell sarcoma, and rhabdoid tumour. Other primary renal neoplasms include primitive neuroectodermal tumour (PNET), renal cell carcinoma, and angiomy-olipoma. Nephroblastoma is the most common renal tumour in children. It is a complex embryonal tumour of metanephric blastemal derivation, which often conta...
Background. Nephroblastoma is the commonest renal tumour seen in children. It has a good prognosis in developed countries with survival rates estimated to be between 80% and 90%, while in Africa it remains low. Method. Retrospective study of patients diagnosed with nephroblastoma who are seen at 4 paediatric oncology units, representing 58.5% of all South African children with nephroblastoma an...
