Objective　To detect molecular subtypes of medulloblastoma, and its correlation with prognosis. Methods　 Surgically treated 32 cases of primary medulloblastoma from 2010-2013 were collected, the molecular subtypes were determined by immunohistochemical detection of GAB1 and YAP1 protein in the sample. Clinical characteristics, imaging features and survival condition of different molecular subtypes were analyzed. Results　Molecular typing of the 32 cases (21 males and 11 females) shows 4 (12.5%) cases of SHH, 7 (21.9%) cases of WNT and 21 (65.6%) cases of non-SHH. There was no significant correlation of molecular subtypes with age, gender and pathological classification. Three-year progression free survival rate in SHH, WNT and non-SHH/WNT subtypes were 75%, 57.1% and 38.1%, respectively. Three-year progression free survival rate was significantly higher in patients under 3 years old group than that in patients over 3 years old group in non SHH/WNT (P=0.047). Conclusions　The prognosis of SHH was better than WNT, WNT was better than non-SHH/WNT type, prognosis in patients under 3 years old group of non-SHH/WNT was better than that in patients over 3 years old group.
