PURPOSE: To examine the influence of age and conditioning with total-body
irradiation (TBI) on the trajectory of cognitive functioning after treatment with
pediatric hematopoietic stem-cell transplantation (SCT). PATIENTS AND METHODS:
Pediatric patients who were scheduled to undergo a SCT were eligible for the
study, with 315 patients completing a baseline assessment. Of these, 183 patients
(58.1%) were alive at 1 year after SCT and completed additional assessments at 1,
3, and 5 years after SCT. Half of the long-term sample (52.1%) received TBI
during conditioning. Cognitive functioning was assessed via age-appropriate
standardized measures. RESULTS: At baseline, there were no differences in
intelligence quotient (IQ) based on age. At 5 years after SCT, the youngest
patients (< 3 years old at baseline) who received TBI demonstrated a
significantly lower IQ than those who did not receive TBI (P = .05). Longitudinal
analyses (piecewise linear mixed-effects models with a knot at 1 year after SCT)
revealed a significant impact of age and TBI over time. The youngest patients
evidenced declines in cognitive functioning during the first year; however,
patients who did not receive TBI largely recovered their functioning in
subsequent years. In contrast, young patients who received TBI failed to recover
the losses experienced during the first year after SCT, demonstrating stability
in their functioning, but at a lower level. CONCLUSION: Our findings clarify the
relationship between TBI and age on cognitive outcomes in pediatric SCT
survivors. Young patients who receive TBI may benefit from early intervention
efforts to minimize cognitive losses during the first year after SCT and to
maximize potential recovery.
