Clinical Management.
Clinical management of patients are detailed on Table 3 . All patients received maximal surgical resection following diagnosis. Residual tumor area was only obtained in post-2008 patients and was greater than 1.5 cm2 in 19 patients (50%). Radiation occurred within 50 days of surgery in 53 patients (60%). Seventy-five patients (84%) received chemotherapy within 60 days of completing radiation. Classic was the most common histological subtype (24%), though a substantial portion of patients were diagnosed with unclassified medulloblastoma (49%). Metastasis at diagnosis was documented in 7 out of 38 (18%) patients in the post-2008 cohort.
