This study evaluated the quality of life and neuropsychologic functioning a
mong patients enrolled between 1989 and 1993 in the First International CNS
Germ-Cell Tumor Study. Quality-of-life questionnaires (Short Form-36 or Ch
ild Health Questionnaire) were completed on 43 patients at median follow-up
of 6.1 years after diagnosis (range, 4.5-8.8 years), and intellectual and
academic testing was performed on 22 patients. Psychosocial and physical fu
nctioning of patients aged 19 years and older at follow-up was within the a
verage range, whereas the same functioning for patients aged 18 years and y
ounger, as reported by their parents at follow-up, was low average and bord
erline, respectively. Overall psychosocial and physical health summary scor
es were positively correlated with age at diagnosis for both groups combine
d. Those who received CNS radiation therapy (n = 29) reported significantly
worse physical health, but similar psychosocial health, compared with thos
e treated without radiation. Neuropsychologic testing indicated full-scale
and verbal IQ, reading, spelling, and math skills in the average range, and
performance IQ in the low average range. Intelligence and math skills were
positively correlated with age at diagnosis. Those with germinomas signifi
cantly outperformed those with nongerminomatous/mixed tumors on all neurops
ychological measures administered. Younger patients diagnosed with CNS germ
-cell tumors are at increased risk for psychosocial and physical problems a
s well as neuropsychologic deficits. Exposure to irradiation adversely affe
cts overall physical functioning, whereas tumor pathology appears to be a s
alient neurocognitive risk factor. Collaborative and randomized studies are
required to further elucidate the late effects arising from factors such a
s age at diagnosis, tumor histology, level of irradiation therapy, and chem
otherapy toxicity among these young and potentially curable patients.
