A multicenter, clinical trial, randomized open label and parallel study has been done since April 1993 on the Chronic Myelogenous Leukemia patients treated with either Interferon (I) + Hydroxyurea (HU) or Interferon + low dose Ara-C (C).

The dose of Interferon is 5 MU 5 days a week, HU 55 mg/kg body weight 5 days a week and Ara-C 15 mg subcutan 5 days a week. The objectives of these study are to compare and contrast the episode of blast crisis, survival, hematological and cytogenetic remission, 39 patients enrolled this study, 33 HI and 6 CI. Dropped out patient was 4 HI group 2 in CI group, 1 more patient in GI group dropped-out during maintenance therapy. Those who still alive are 3 in HI and 2 in CI. The reason for dropping out was misdiagnosis, last to follow up, economic hardship or had bone marrow transplant. There is 1 biologic remission in HI group.
