INFANTS WITH MEDULLOBLASTOMA - A SINGLE INSTITUTION REVIEW OF SURVIVAL

Although the prognoses of children with medulloblastoma have improved dramatically over the last several decades, the reported survival for very young children with this tumor remains poor. We undertook a retrospective review of patients less than 36 months of age at the time of the diagnosis of a medulloblastoma who were treated at our institution during a 36-year period. Of 28 such patients, 10 patients are presently surviving without disease at a median of 150 months from diagnosis. The presence of a metastatic tumor at the time of diagnosis was identified as a significant indicator of a poor prognosis, and all completely staged patients without metastasis are surviving without a recurrence of disease. This report suggests that the survival of very young children with a medulloblastoma may not be as poor as has been previously reported, particularly if a disseminated tumor is not present at the time of diagnosis.
