Abstract

The profile of renal tumors in children less than 15 years of age during the period 1991-1997 is presented. Among the 37 children with kidney tumors, 29 (78.4%) had Wilms' tumor. There was also a 20-year-old female with Wilms' tumor. The median age at presentation was 2.6 years (range 2.5 months to 20 years). 66.7% of the cases diagnosed were < or = 3 years and 90% were < or = 6 years. Five cases were under one year of age. The male to female ratio was 2:1. Twenty-two cases (73.3%) were triphasic and 7 (23.3%) were biphasic. Only one case was monophasic with blastemal component. Five cases (16.7%) showed nephrogenic rests in the uninvolved renal parenchyma and one case had nephroblastomatosis. The tumor was favorable in 26 cases (86.7%) and unfavorable in 4. Fourteen cases were in-patients while 16 were outside referrals. The pathological (10 cases whose specimens were sent from other centers) and clinicopathological (13 hospitalized patients) staging showed 10 cases (43.5%) with stage 1, 4 cases (17.4%) with stage 2, and 7 cases (30.4%) with stage 3. In two cases (8.7%), there was stage 4 disease. The length of the follow-up period in the 13 hospitalized patients ranged from 7 days to 5 years 5 months (median 14 months). There was one recurrence and one death after 2 years of diagnosis.
