Objectives To assess self-reported quality of life (QOL) in a large multicenter cohort of adolescent and young adults surviving Fontan. Study design Cross-sectional. The Pediatric Quality of Life Inventory (PedsQL) was administered to 408 survivors of Fontan ages 13–25 years enrolled in the Pediatric Heart Network Fontan Follow-up Study. Subjects also completed either the Child Health Questionnaire (CHQ-87, age < 19years) or Short Form 36 (SF-36, age ≥19 years). PedsQL data were compared with matched controls without a chronic health condition. Correlations between the measures were examined. Results Mean PedsQL scores for subjects receiving Fontan were significantly lower than those for the control group for physical and psychosocial QOL (P<0.001). Overall, 45% of subjects receiving Fontan had scores in the clinically significant impaired range for physical QOL with 30% in the impaired range for psychosocial QOL. For each 1 year increase in age, the physical functioning score decreased by an average of 0.76 points (p=0.004) and the emotional functioning score decreased by an average of 0.64 points (p=0.03). Among subjects ≥ 19 years of age, the physical functioning score decreased by an average of 2 points for each year increase in age (p=0.02). PedsQL scale scores were significantly correlated with conceptually related CHQ-87 (p<0.001) and SF-36 scores (p<0.001). Conclusions Survivors of Fontan are at risk for significantly impaired QOL which may decline with advancing age. Routine assessment of QOL is essential to inform interventions to improve health outcomes. The PedsQL allowed QOL assessment from pediatrics to young adulthood.

Purpose: To determine in a prospective randomized trial the effect on survival, progression-free survival, and patterns of relapse of a decrease in the neuraxis radiation dose from 3,600 cGy in 20 fractions to 2,340 cGy in 13 fractions in patients with newly diagnosed medulloblastoma between 3 and 21 years of age with low T stage (T₁, T₂ and T_3A), minimal postoperative residual tumor, and no evidence of dissemination (Mo). Methods and Materials: Between June 1986 and November 1990, the Children’s Cancer Group and the Pediatric Oncology Group randomized 126 patients in a two-arm study comparing the two different doses of neuraxis irradiation. In both arms, the posterior fossa received 5,400 cGy in 30 fractions. All patients were staged with myelography, postoperative lumbar cerebrospinal fluid cytology, and postoperative contrast-enhanced cranial computerized tomography to ensure no evidence of dissemination and no more than 1.5 cm³ residual tumor volume. Overall survival, progression-free survival, and patterns of recurrence were carefully monitored. Prospective endocrine and psychometric studies were performed to determine the benefit of decreasing the neuraxis radiation dose. Results: Following an interim analysis at a median time on study of 16 months, the study was closed, since a statistically significant increase was observed in the number of all relapses as well as isolated neuraxis relapses in patients randomized to the lower dose of neuraxis radiation. Conclusions: In patients with newly diagnosed medulloblastoma considered to have a good prognosis on the basis of low T stage, minimal residual tumor after at least subtotal resection, and no evidence of dissemination after thorough evaluation, there is an increased risk of early relapse associated with lowering the dose of neuraxis radiation from 3,600 cGy in 20 fractions to 2,340 cGy in 13 fractions.

Although survivals of infants with malignant brain tumors are worse than any other age group, one possible exception to this rule are the malignant gliomas. Eighteen children less than 3 years of age with malignant gliomas (glioblastoma multiforme, anaplastic astrocytoma and malignant glioma) were treated on the Pediatric Oncology Group regimen of prolonged postoperative chemotherapy and delayed irradiation, (1986-1990). Of 10 children evaluable for neuroradiologic response, 6 had partial responses (> 50% reduction) to two cycles of cyclophosphamide and vincristine. Progression free survivals at 1,3 and 5 years were 54.25% +/- 12, 43% +/- 16 and 43% +/- 23 respectively. Survivals at 5 years were 50% +/- 14. Four children were not irradiated after 24 months of chemotherapy due to parental refusal and none have developed recurrent disease. Neither degree of surgical resection, presence or absence of metastases, nor pathology influenced survival but this may reflect small sample size. This study suggests that some malignant gliomas in infants are chemotherapy sensitive and may be associated with a good prognosis. Why infants with these high-grade gliomas fare better than adults is not clear. It is likely that there is something intrinsically different about them that cannot be identified on routine pathologic examination.

Reduced-dose neuraxis irradiation (23.4 Gy) is associated with increased risk of early relapse, early isolated neuraxis relapse, and lower 5-year EFS and overall survival than standard irradiation (36 Gy). The 5-year EFS for patients receiving standard-dose irradiation is suboptimal, and improved techniques and/or therapies are needed to improve ultimate outcome. Chemotherapy may contribute to this improvement.
