PURPOSE: To assess the utility of surveillance neuroimaging in detecting
recurrent disease in patients treated for medulloblastoma. PATIENTS AND
METHODS: Records and scans of 59 consecutive patients treated for
medulloblastoma between 1984 and 1993 in one institution were
retrospectively reviewed. RESULTS: Nineteen of 59 patients had recurrence
of tumor, of which 17 were available for this study. Eleven of the 17
recurrent patients were asymptomatic at the time of detection. The median
time to recurrence was 13 months (range, 3 to 90). CONCLUSION: Surveillance
scanning detected a majority of recurrences before onset of symptoms.
Although the outcome of those with recurrent disease remains poor, early
detection with minimum disease provides the best setting in which to test
newer therapies. Patients and their parents also were more likely to elect
pursuing further treatment when relapse was detected asymptomatically.
