1. Gy groups, allowing them more time for height loss. In addition, younger age at diagnosis is correlated with greater height loss anyway. This difference in median age at diagnosis arises because 18 Gy cranial irradiation as prophylaxis has only been widely used since 1981 so those at final height now are mainly those who were older at diagnosis. Other workers have found similar changes in standing height after cranial irradiation, though the numbers reported at final height after 18 Gy have been small.2 4 5
