Acute lymphoblastic leukemia (ALL) is managed through a structured, protocol-driven approach. First-line treatment begins with a defined preparatory phase before the full course of therapy is undertaken.
The protocol opens with a pre-phase that uses a corticosteroid, which may be given alone or in combination with one or more additional agents. Supportive measures are also incorporated during this phase to manage potential complications. The complete multi-step regimen — including all subsequent phases, decision points, and clinical criteria — is available in the full structured protocol.
