Background: The literature contains conflicting reports on the value of low insulin-like growth factor 1 (IGF-1) levels in predicting radiation-induced growth hormone (GH) deficiency (GHD) in childhood cancer survivors (CCS). These reports often involve small samples of patients who have received irradiation or mixed cohorts including non-irradiated subjects. Objective: We undertook an analysis of the predictive value of low IGF-1 in CCS at risk for GHD after cranial radiotherapy involving the hypothalamic-pituitary (HP) area in a large single-centre cohort. Methods: We performed a retrospective analysis on 158 CCS diagnosed with GHD between January 1, 2003 and October 31, 2017 and identified 117 patients who received radiation for tumours not direct ly involving the HP area. Results: In this cohort, IGF-1 levels <–2 standard deviation scores (SDS) had a sensitivity of 31.9% for GHD; however, they were statistically more frequent (p = 0.0023) and had a higher sensitivity (45.6%) among patients with severe GHD. At final height reassessment, IGF-1 <–2 SDS had a sensitivity of 35.0% for GHD, but a positive predictive value of 100%. Finally, pretreatment IGF-1 values showed no correlation with the number of impaired pituitary hormonal axes in patients with multiple pituitary deficiencies. Conclusions: IGF-1 levels <–2 SDS showed a low sensitivity at predicting radiation-induced GHD both in childhood and in adulthood, but a high positive predictive value for GH status at final height reassessment.

Abstract Abstract 506FN2 Introduction Over the last decades childhood cancer survival rates have improved significantly. Currently, 70–80% of patients become long term cancer survivors. It has been estimated that 1 out of 640 young adults in the U.S. is a survivor of childhood cancer. Consequently, the incidence of late, treatment-related complications is increasing. Endocrine sequelae, such as the metabolic syndrome, osteopenia, sub fertility, thyroid dysfunction and growth hormone deficiency represent an important category of such late effects. Growth hormone deficiency (GHD) in childhood cancer survivors, mainly caused by cranial radiotherapy, is reflected by low levels of insulin like growth factor 1 (IGF-I). Whereas the value of IGF-I measurement for the diagnosis of GHD is controversial, low IGF-I levels are associated with high body mass index and high visceral fat percentage. However the clinical relevance of low IGF-I levels in long term childhood cancer survivors is not extensively studied. In this study we evaluated whether IGF-I is useful as a marker for altered body composition and growth hormone deficiency in this group. Methods We retrospectively analyzed data of 610 adult childhood cancer survivors, retrieved from the Rotterdam late effects clinic, which starts 5 years after cessation of therapy. Median age at diagnosis was 6 years (interquartile range (IQR) 3–11) and follow up time was 18 years (13–24). We assessed IGF-I Z-scores, anthropometrical measures, growth hormone stimulation tests in patients with clinical suspicion of GHD and measures of body composition (assessed by dual X-ray absorptiometry, Lunar Prodigy). Results Cranial irradiated acute leukaemia survivors (25 Gy (24–25)) and locally irradiated brain tumour survivors (42 Gy (35–54)) had significantly lower IGF-I Z-scores (p<0.001), lower height SDS (p<0.001), higher body mass index (p=0.01), higher waist-hip ratio (p=0.001), higher visceral fat percentage (p<0.001), higher total fat percentage (p<0.001) and lower lean body mass (p<0.001), compared to non cranial irradiated survivors. IGF-I did not show a strong correlation with BMI (r=-0.12, p=0.04), waist hip ratio (r=-0.15, p=0.01), total fat percentage (r=-0.14, p=0.02) and lean body mass (r=0.15, p=0.01). In the patients with low IGF-I levels who had growth hormone stimulation, IGF-I Z-scores did not significantly differ between the patients with and without severe GHD (p = 0.39). Conclusion This study shows that there is a limited value of IGF-I as marker for alterations in body composition, and confirms the fact that low IGF-I levels are not predictive for GHD, in a large cohort of childhood cancer survivors. Therefore the use of IGF-I should not be encouraged in adult childhood cancer survivors. Disclosures: No relevant conflicts of interest to declare.

PURPOSE Between 10% and 20% of childhood cancer survivors (CCS) experience impaired growth, leading to small adult height (SAH). Our study aimed to quantify risk factors for SAH or growth hormone deficiency among CCS. METHODS The French CCS Study holds data on 7,670 cancer survivors treated before 2001. We analyzed self-administered questionnaire data from 2,965 CCS with clinical, chemo/radiotherapy data from medical records. SAH was defined as an adult height ≤ 2 standard deviation scores of control values obtained from a French population health study. RESULTS After exclusion of 189 CCS treated with growth hormone, 9.2% (254 of 2,776) had a SAH. Being young at the time of cancer treatment (relative risk [RR], 0.91 [95% CI, 0.88 to 0.95] by year of age), small height at diagnosis (≤ 2 standard deviation scores; RR, 6.74 [95% CI, 4.61 to 9.86]), pituitary irradiation (5-20 Gy: RR, 4.24 [95% CI, 1.98 to 9.06]; 20-40 Gy: RR, 10.16 [95% CI, 5.18 to 19.94]; and ≥ 40 Gy: RR, 19.48 [95% CI, 8.73 to 43.48]), having received busulfan (RR, 4.53 [95% CI, 2.10 to 9.77]), or > 300 mg/m2 of lomustine (300-600 mg/m2: RR, 4.21 [95% CI, 1.61 to 11.01] and ≥ 600 mg/m2: RR, 9.12 [95% CI, 2.75 to 30.24]) were all independent risk factors for SAH. Irradiation of ≥ 7 vertebrae (≥ 15 Gy on ≥ 90% of their volume) without pituitary irradiation increased the RR of SAH by 4.62 (95% CI, 2.77 to 7.72). If patients had also received pituitary irradiation, this increased the RR by an additional factor of 1.3 to 2.4. CONCLUSION CCS are at a high risk of SAH. CCS treated with radiotherapy, busulfan, or lomustine should be closely monitored for growth, puberty onset, and potential pituitary deficiency.
