INTRODUCTION: The treatment of childhood leukemia has improved substantially over the last decades and now 65-75% of the patients recover. With increasing number of survivors it is important to know the long-term and late effects of leukemia and leukaemia treatment.
PATIENTS: Of the 31 children diagnosed with leukemia in Iceland from 1981 to 1990, twenty were enrolled in the study. Average age at enrollment was16 years and 8 months (16:8) and average time since treatment ended was 8:3.
METHODS: The study was carried out at the Children's Hospital at the University Hospital Iceland where patients were examined and data was gathered on height, weight, hearing, cognitive functions, bloodvalues, immunoglobulins and renal, endocrine, heart, liver and respiratory functions.
RESULTS: The children studied were on average 0.48 standard deviations below target height and their body-mass index was higher at the time of study than at diagnosis. Two children had obvious obstructive lung disease. No abnormalities were found in complete blood count nor heart, liver or kidney functions. Two patients were found to have impaired hearing not attributable to acoustic trauma. In some cases abnormal values were found in immunoglobulin classes and 12 patients had decreased serum IgG2. Six needed remedial reading lessons. Three patients needed hormone replacement therapy.
DISCUSSION: Minor impact on height and weight was found but the effects on lungs and hearing were inconclusive. Despite markedly decreased serum IgG2 the patients were not more prone to infections. The most obvious effects were on the endocrine system and performance at school. We conclude that the sequelae of childhood leukemia treatment in Iceland are significant and long-lasting, underlining the necessity of a careful long-term follow-up.
