Patients with evaluable information on the type of salvage therapy, without CNS involvement and with Ph/BCR-ABL–negative ALL.
HDAC indicates high-dose cytarabine; HDMTX, high-dose methotrexate; and Mitox, mitoxantrone.
No percentage was calculated in subgroups with total number of cases less than 10.
χ2 test.
Patients received SCT as their salvage treatment; and CR rate indicates the remission rate after SCT.
