Brief Summary: This review analysed 15 original studies reporting the effects of radiation therapy (RT) on thyroid gland in childhood cancer survivors (CCS). A relationship between RT dose to the thyroid gland and risk of hypothyroidism could be extrapolated from 8/15 studies. Risk of compensated hypothyroidism increased with RT dose to the thyroid: it was 12%, 25% and 44% at 10, 20 and 30 Gy, respectively. Similarly, the risk of overt hypothyroidism was 4%, 7% and 13% at 10, ...

Brief Summary: The nationwide Dutch Childhood Cancer Survivor (CCS) LATER cohort study assessed by questionnaire the reproductive outcomes and reproductive health care in 1317 male CCS and 407 male siblings. This included 491 CCS and 185 siblings who expressed a previous or current desire for children. Fewer CCS than siblings reported having biological children (65% vs. 88%). The type of conception was similar between CCSs and siblings (spontaneous conception in 90% of both gr...

Brief summary: This Dutch cross-sectional study aimed to assess risk factors for impaired bone mineral density (BMD) and fractures (particularly vertebral fractures) in adult survivors of childhood cancer. The relationships between low BMD (Z-score ≤–1), very low BMD (Z-score ≤–2), fractures, vertebral fractures, and demographic, treatment-related, endocrine, and lifestyle-related factors was analyzed by logistic regression.<p class=...
