Chronic Health Conditions and Academic Achievement: A Childhood Cancer Survivor Study Report

To examine associations between special education, chronic health conditions (CHCs), and college graduation in survivors of childhood cancer and their siblings.

Childhood Cancer Survivor Study participants included 23,082 5-year survivors (53.7% male; median [IQR] age at diagnosis, 6 [3-13] years; age at evaluation, 31.0 [24-39] years; treated between 1970 and 1999) and 5,037 siblings (47.7% male; 36.0 [28-44] years at evaluation). Special education use, reasons for special education, CHCs, and college graduation were self-reported. Primary cancer diagnosis and treatment exposures were abstracted from medical records. Comparisons between survivors and siblings were made using chi-square statistics; demographic and treatment factors associated with outcomes were examined using modified Poisson regression models.

More survivors reported special education use than siblings (26.5% v 8.6%; relative risk [RR], 2.55 [95% CI, 2.32 to 2.80]). Of those survivors and siblings who had special education services, use was highest between kindergarten and fifth grade (64.4% of survivors and 71.9% of siblings in kindergarten-fifth grade, 14.4% of survivors and 12.5% of siblings in sixth-eighth grade, and 9.2% of survivors and 9.0% of siblings in ninth-12th grade), and primarily attributable to learning and concentration problems. Despite receiving special education, survivors were less likely to graduate college compared with siblings requiring special education (RR, 0.76 [95% CI, 0.66 to 0.88]). Risk for not graduating college included history of CNS tumor (RR, 1.47 [95% CI, 1.40 to 1.55]), cranial irradiation (20-29 Gy, RR, 1.16 [95% CI, 1.09 to 1.25]; 30-49 Gy, RR, 1.37 [95% CI, 1.26 to 1.49]; ≥50 Gy, RR, 1.35 [95% CI, 1.28 to 1.42]), or the presence of a severe, disabling or life-threatening CHC (Common Terminology Criteria for Adverse Events grade 3-4, RR, 1.15 [95% CI, 1.07 to 1.24]).

Cognitive problems and CHCs increase risk for not graduating college; these problems are not alleviated by special education.
