A 74-year-old woman was admitted in October 1988 with anemia and leukocytopenia. Hematologic investigations established a diagnosis of hypoplastic acute leukemia. She received a low dose of cytosine arabinoside (LDAC: 10 mg/m
2 every 12hours) subcutaneously for 21 days and achieved complete remission (CR) one month later. After one course of LDAC of 14 days, she received LDAC of 21 days every 5 to 6 months as maintenance therapy till April 1993. She has been in remission for 6 years. Intensification therapy with LDAC every 5 to 6 months might be useful in maintaining remission for hypoplastic acute leukemia.
