Clinical reports of small numbers of pediatric
brain tumor patients observed for brief periods suggest that long-term survivors continue to have major handicaps into adulthood. To quantify these late effects we interviewed 342 adults (or their proxies) who had CNS
tumors diagnosed before the age of 20 between 1945 and 1974, survived at least 5 years, and reached 21 years of age. Survivors were 32 years old on average at follow-up. When compared with 479 matched siblings as controls. CNS
tumor survivors were more likely to have died or to have become mentally incompetent sometime during the follow-up period. They were more likely to be at risk for such adverse outcomes as unemployment (odds ratio [OR], 10.8; 95% confidence interval [CI], 4.6 to 25.7], to have a health condition that affected their ability to work (OR, 5.9; CI, 3.7 to 9.4), to be unable to drive (OR, 28.8; CI, 6.9 to 119.9), or to describe their current health as poor (OR, 7.8; CI, 1.7 to 35.7). Unfavorable outcomes were more frequent in male survivors than in females, in those with
supratentorial tumors compared with infratentorial ones, and in those who received
radiation therapy. As clinicians consider improving
therapies, they should anticipate late effects, such as those we observed, and attempt to target subgroups for interventions that may improve subsequent quality of life.
