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=...

Brief summary: This cross-sectional study explored the risk factors for pre-frailty, frailty, and sarcopenia in a cohort of Dutch childhood cancer survivors diagnosed between 1963 and 2001.Frailty was defined as the presence of at least two (pre-frailty) or three (frailty) of the following criteria: low appendicular lean mass (low percentage of lean tissue in the limbs assessed by dual-energy X-ray absorptiometry, DXA), low muscle strength (measured with...
