• Heights, height velocities, weights, and weight velocities were measured serially in 21 patients with acute lymphocytic leukemia (ALL) who had survived three to five years in continuous complete remission. These patients were assigned randomly to treatment regimens that varied according to whether cranial irradiation was used. Patients receiving cranial irradiation had lower height velocities during therapy than normal subjects and patients not receiving cranial irradiation. Twenty-two other children with ALL, who were irradiated but not randomized, exhibited similar alterations in growth. These results indicate that cranial irradiation, and not leukemia or antileukemic chemotherapy, causes reduced growth.
