SECOND PRIMARY NEOPLASMS IN CHILDREN

Abstract
The records of the Children's Hospital Medical Center were reviewed for the years 1938 to 1963. Case histories are presented of children treated for malignancies who developed second tumors, lymphomas or leukemia. Our study revealed that the approximate incidence of double primary tumors in children with malignancy, seen at our Center, was 0.5 per cent, or 5.0 per cent of all children who received radiation in doses in excess of 1,000 rads and who have survived free of disease at least 2 years.
