INTRODUCTION: The use of rehabilitation services to address musculoskeletal, neurological and cardiovascular late effects among childhood cancer survivors could improve physical function and health-related quality-of-life (HRQL). We describe physical therapy (PT) and chiropractic utilization among childhood cancer survivors and their association with HRQL. METHODS: The sample included 5+ year survivors from the Childhood Cancer Survivor Study (N = 9,289). Questions addressing use of PT or chiropractic services and HRQL (Medical Outcomes Survey Short Form (SF-36)) were evaluated. Multivariable regression models compared PT and/or chiropractic utilization between survivors and siblings, and by diagnosis, treatment and demographic characteristics; associations between chronic disease, PT/chiropractic use, and HRQL were similarly evaluated. RESULTS: Survivors were not more likely to use PT (OR 1.0; 95% CI 0.8-1.2) or chiropractic (OR 0.8; 95% CI 0.7-1.0) services than siblings. More survivors reported using chiropractic (12.4%) than PT (9.2%) services. Older age and having health insurance were associated with utilization of either PT or chiropractic services. Grade 3-4 chronic conditions and a CNS tumor or sarcoma history were associated with PT but not with chiropractic service utilization. Survivors with musculoskeletal (OR 1.8; 95% CI 1.1-2.9), neurological (OR 3.4; 95% CI 1.6-6.9), or cardiovascular (OR 3.3; 95% CI 1.6-6.9) chronic conditions who used PT/chiropractic services were more likely to report poor physical health than survivors who did not use services. CONCLUSIONS: The reported prevalence of PT/chiropractic among survivors is consistent with that reported by siblings. Severity of late effects is associated with service use and with reporting poor physical health. IMPLICATIONS FOR CANCER SURVIVORS: Long-term childhood cancer survivors do not appear to utilize rehabilitation services to optimize physical function and support increased HRQL.
