192 patients suivis à l’IGR • Cachexie diencéphalique: 20%

– Diabète insipide (8%) plus fréquent après chirurgie.

LEPR polymorphism may influence obesity in female survivors of
childhood ALL, particularly those exposed to cranial radiation.

Morbidité endocrinienne
CCSS BT vs siblings
• Hypothyroïdie: RR=14
• Déficit en GH: RR=278
• Nécessité d’induire la puberté: RR=86
• Ostéopénie: RR=25
• Parfois présent avant l’irradiation lorsqu’on
fait des dosages dynamiques (TSH, GH).

Obésité
• Le BMI n’est pas lié aux doses de RT mais plutôt à la souffrance de l’hypothalamus, comme dans les craniopharyngiomes.
• Le BMI est inversement corrélé à l’âge à la puberté.
• Le BMI est plus élévé chez les filles jeunes au diagnostic.
• Risque accru d’AVC (RR=43) et de thromboses (RR=6) et d’angor (RR=2).

Neuro-oncology LTFU clinic
vs general LTFU clinic vs general ped.onc.care
• More neuropsyc. testing
• Longer surveillance imaging
• More GH use in medulloblastoma survivors
• More GH use through adulthood
• Effect on cognition

– Quik et al, Growth Horm IGF Res 2012 Jan.
GH in adult cancer survivors (pediatric
ALL) lowers cardiovascular risks
• All treated with CSI (Lund University, SWE).
• 16 received GH, 13 not.
• Five years of therapy led to significant improvements (compared to 8
years without therapy) in plasma glucose (-0.5 vs 0.6 mmol/L, p =
0.02), high-density lipoprotein cholesterol (0.20 vs -0.01 mmol/L, p =
0.008), and apolipoprotein B/A1 ratio (-0.1 vs 0.0, p = 0.03). In
addition, the prevalence of metabolic syndrome fell significantly (p =
0.008) in those treated with growth hormone.
• No difference in QOL or physical activity or cardiovascular functions.
• Erfurth M, J Endocrin. Metab. 2010

Hypopituitarism following radiotherapy revisited.
• Dose relationship:
– If < 30Gy, GH deficiency only in 30%.
– If > 30 Gy, GH deficiency in 50-100%, Gonadotropin deficiency in 20-30%, TSH and ACTH deficiencies in 5-10%.
– The higher the dose, the sooner the deficit(s).
– Precocious puberty with doses as low as 30 Gy, especially in girls.
– Hyperprolactinemia if surgical hypothalamic damage plus high-dose irradiation in young women.
Ostéopénie
• Connue dans les TC depuis 1990.
• Plus fréquente après une TC (67% vs 27%).
• Impact de l’irradiation spinale.
• Plus de douleurs et de fractures et une moins bonne qualité de vie en cas d’ostéopénie.
• Efficacité de la supplémentation vitamino-calcique.
Osteopenia
• Bilariki et al, Horm Res Paediatr 2010
• 51 patients (metabolic/radiologic)
• No significant changes of Z scores
• Survivors of childhood solid cancer have
high rates of insufficient calcium intake
(75%), vitamin D deficiency (62%), low
bone mass (32% spine/21%femur) and
fractures (20%, not correlated with BMD).
Ostéoporose chez l’adulte
survivant d’une TGM
• 28 survivants.
• Ostéodensitométrie.
• 25 % d’ostéoporose, 43 % d’ostéomalacie.
• Plus fréquent chez les hommes (92%).
• Plus fréquent chez ceux dont la GH est
introduite tard à l’âge adulte.
