Abstract:
Authors analyzed the results of treatment in 49 cases of medulloblastoma who had been operated upon at the Seoul National University Hospital from January 1972 to June 1987. There were 2 cases(4%) of postoperative mortality(death within postoperative one month) and 13 cases of late moratlity. The 3-year overall survival rate was 49.3% and 3-year disease-free survival rate was 48.5%. The risk period of recurrence was about 2 years after surgery. The 3-year survival rate was significantly better in "grow total resection" group, "radiation dose more than 50 Gy" group, and group II(23 cases operated after July 1982) (p<0.05). The rate of posterior fossa recurrence was lower in "gross total resection" group for the patients who received posterior fossa irradiation of more than 50 Gy.
