Abstract
Purpose
Survivors of childhood leukemia are at risk of growth impairment due to intensive chemotherapy and radiation treatment. This study investigated the auxological and biochemical characteristics of childhood leukemia survivors diagnosed with growth hormone deficiency (GHD) and the changes in these parameters after 1 year of growth hormone (GH) treatment.
Methods
A total of 24 children diagnose with GHD after leukemia treatment were analyzed. Clinical and biochemical data were collected retrospectively at leukemia diagnosis, GHD diagnosis, and 1 year after GH treatment. Standard deviation score (SDS) was calculated based on the age- and gender-adjusted population.
Results
Of the 24 children included in this study, 19 received GH treatment. The median age at GHD diagnosis was 12.3 years, and the median delay in bone age was 1.46 years. Height SDS decreased from -0.69 at leukemia diagnosis to -2.58 at GHD diagnosis (p < 0.001). Change in height SDS with and without GH for 1 year was 0.35 and -0.21, respectively (p = 0.044). In regression analyses, higher height SDS at GHD diagnosis and less decrement of the height SDS between leukemia and GHD diagnoses were positively correlated with height SDS after GH treatment.
Conclusion
GH treatment could be beneficial and safe for improving height in childhood leukemia survivors with GHD. Height SDS at GHD diagnosis and decrement of height SDS between leukemia and GHD diagnosis could be a potential factor in predicting the therapeutic effect. Close auxological monitoring is recommended for any childhood leukemia survivors who experience post-treatment height decline.
