Abstract

Osteoporosis poses a significant concern for childhood cancer survivors (CCS). While recommendations for surveillance and management of bone mineral density (BMD) exist, no systematic review and meta-analysis has been undertaken to quantify BMD Z-scores in childhood cancer patients undergoing cancer treatment and survivors who have completed treatments. Accordingly, we conducted a systematic review with a 3-level mixed-effects meta-analysis to examine the course of BMD Z-scores in childhood cancer patients and survivors and identified possible moderators using meta-regression models. A systematic search was conducted in CINAHL, Embase, PubMed, SPORTDiscus, and Web of Science databases from inception to November 2023. We included studies that involved children and adolescents diagnosed with cancer before the age of 18 who were undergoing cancer treatment or had completed treatments and reported lumbar spine, hip/femoral neck, or total body BMD Z-scores derived from dual-energy x-ray absorptiometry. Forty-nine studies (4547 participants) were included in the meta-analysis. BMD Z-scores across different sites decreased with respect to baseline in children undergoing cancer treatment (mean difference: − 0.36, 95% CI − 0.62 to − 0.11; p =.01) and remained low following treatment in child and adolescent CCS (lumbar spine: − 0.85 SD, 95% CI − 1.17 to − 0.54; p <.001; hip/femoral neck: − 1.03 SD, 95% CI − 1.38 to − 0.68; p <.001), and adult CCS (lumbar spine: − 0.46 SD, 95% CI − 0.67 to − 0.26; p <.001; hip/femoral neck: − 0.36 SD, 95% CI − 0.57 to − 0.16; p <.001). Hip/femoral neck BMD Z-scores were moderated by age at assessment (p =.006), time from diagnosis (p =.004), sex (p =.037), and height (p =.026). Lumbar spine BMD Z-scores were moderated by age at assessment (p =.018), and sex (p =.015). In conclusion, childhood cancer patients and survivors experience reductions in BMD. Future research should evaluate the implications of regular physical activity, targeted exercise medicine, and nutrition therapy as first-line countermeasures to mitigate the declines in bone health.
