Late effects of tele cobalt 60 therapy on bones and soft tissues were studied radiologically in 24 patients with neuroblastoma and Wilms' tumor. The degree of changes in spinal bodies was influenced by the dose of irradiation as well as the age of patients at the time of irradiation. In patients who had 15 to 19 Gy of irradiation at the ages under one year old, a moderate to severe degree of changes was observed. Many patients showed atrophies of iliac bone, ribs, and erector spinae and psoas muscles on the side of the irradiation. In patients who were equal to or over 12 y.o. at the time of the examination, the degree of atrophy of erector spinae muscles on the side of the irradiation was greater than that of the patients who were less than 12 y.o.. Scoliosis was observed in 71% of patients and it had a tendency to aggravate at puberty. Because there was a significant correlation between the degree of scoliosis and the severity of the atrophic erector spinae muscle, the latter was thought to contribute much to the developement of the former. At present, all patients are living with no limitation of their daily activities and no one needs medical care.
