In the last decade, 13-cis-retinoic acid (13-cis-RA) has been added to the treatment of patients with high-risk neuroblastoma. In survivors of neuroblastoma, short stature is consistently observed. Causes include growth hormone deficiency and poor growth of irradiated long bones. Within the survivorship program at CHOP, we have observed that a number of these patients also have advanced bone ages. Children treated with 13-cis-RA are at risk for advanced bone age that may dramatically impact their linear growth. Ongoing evaluation is necessary to examine the effect of 13-cis-RA on final adult height and to inform clinical practice in this cohort.
