Adult nephroblastoma--five cases treated by surgery, radiotherapy and chemotherapy.

Nephroblastoma in adults is rare; consequently very little experience of treatment for adult cases has been reported. We report five cases of adult nephroblastoma managed by nephrectomy, radiotherapy and combination chemotherapy. The treatment schedules were derived from childhood nephroblastoma regimens. However, four of the five patients were dead within 12 months of nephrectomy and all five had progression of disease whilst on combination chemotherapy. A good prognosis should not be anticipated for adult nephroblastoma. The chemotherapy schedules which are so successful in childhood nephroblastoma may require modification to improve prognosis in adults.
