The LSA2 L2 protocol evolved from ALL protocols used at the Memorial Sloan-Kettering Cancer Center in the early 1960s. The LSA2 L2 protocol features 3 phases of therapy—namely, induction, consolidation, and repeated cycles of maintenance—given over a total of 2-3 years. [60] Methotrexate is administered intrathecally for CNS prophylaxis throughout treatment. When this protocol was first described, it included irradiation of sites of bulky disease; however, radiation is no longer routinely applied.
