Cytarabine is the core chemotherapy for acute myeloid leukaemia, given with an anthracycline as the classic 7+3 induction and at high doses for consolidation; it is also injected into the spinal fluid to treat or prevent leukaemia in the brain.
Cytarabine was approved in 1969 and remains, with an anthracycline, the remission-induction standard in acute non-lymphocytic leukaemia of adults and children; the label also covers acute lymphocytic leukaemia and blast-phase CML, and intrathecal use for prophylaxis and treatment of meningeal leukaemia. High-dose cytarabine consolidation (CALGB 8525) defined post-remission therapy for favourable-risk AML, and it partners fludarabine (FLAG), cladribine and midostaurin, gemtuzumab or venetoclax in modern regimens. A liposomal co-formulation with daunorubicin (CPX-351, Vyxeos) has its own record. Cerebellar toxicity at high doses, conjunctivitis (steroid eye drops) and profound myelosuppression are characteristic.
Converted to ara-CTP, which competitively inhibits DNA polymerase and is incorporated into DNA, halting chain elongation during S phase.

CPX-351 is the preferred intensive induction for fit older patients with secondary or therapy-related AML in many centres, mainly as a bridge to allogeneic transplant.
One of the few maintenance strategies in lymphoma that improved overall survival rather than only progression-free survival, and the reason three years of rituximab became standard after autologous transplantation in mantle cell lymphoma.
MATRix became the reference induction for fit patients with primary CNS lymphoma and the control arm of later randomised trials.
