Reporting Groups
  Description
6-mercaptopurine All patients received basic 6-mercaptopurine and in addition high-dose methotrexate(HDM) at 3 week intervals ((3 3-week intervals) in total) and PEG-asparaginase at 2 week intervals(5 dosis in total) . Patients received dose increments of 6-mercaptopurine 14 days after High-dose methotrexate if the myelotoxicity was acceptable
