Long-term effects of androgen combined with low dose all-trans-retinoic acid on myelodysplastic syndrome: follow-up of 60 cases

To investigate the long-term effects of androgen combined with low dose all-trans-retinoic acid on myelodysplastic syndrome (MDS). Sixty-two MDS patients, 48 with RA, 2 of RAS, 9 with RA with excess of blasts (RAEB), 2 with RAEB-transformation (RAEB-t ), and 1 with chronic myelogenous-monocytic leukemia (CMML) according to the FAB subtype standard, received stanazolol (6 mg/d) or danazol (600 mg/d) and low dose all-trans-retinoic acid (ATRA 10 mg/d). Three months later the treatment was discontinued on 22 patients that showed ineffective and 2 more patients withdrew from the treatment due to exacerbation. The remaining 36 patients were treated according to the original protocol, and the doses of these 2 drugs were reduced by half until the condition was exacerbated. Follow-up was conducted for 47 (34-78) months. After 6 months of treatment, complete remission (CR) was seen in 1 patient, partial remission (PR) in 6 patients, and hematologic Improvement (HI) in 19 of the 60 patients evaluated with a response ra
