Offspring of patients treated for unilateral Wilms' tumor in childhood.
Twenty-seven women and the wives of nine men who survived unilateral Wilms' tumor in childhood had a total of 59 live born offspring. Among the 33 infants born to women who had received orthovoltage abdominal irradiation, ten weighed less than 2500 g at birth and three died during the perinatal period. In addition, one term infant of normal weight died of complications of a breech delivery. Only one of 26 infants born to the wives of Wilms' tumor patients and unirradiated female patients weighed less than 2500 g at birth and none died. The frequency of congenital malformations and spontaneous abortions in this series was not increased, and no offspring has developed cancer. The findings suggest that the risk of Wilms' tumor is low among progeny of survivors of nonfamilial, unilateral lesions. Damage from abdominal irradiation given to girls with Wilms' tumor may predispose them to the subsequent delivery of low birthweight children.
