title: Treatment of myelodysplastic syndromes with daily oral idarubicin. A phase I-II study.
abstract: BACKGROUND
  Idarubicin, a new anthracycline analogue, is available in an oral preparation, and responses have been observed using relatively aggressive therapy in patients with myelodysplastic syndromes (MDS). The authors studied whether a chronic low-dose schedule would be effective but less myelotoxic.
  
  
  METHODS
  Forty-two patients with MDS received daily low-dose oral idarubicin in 5-week courses that included 3 weeks of treatment, followed by a 2-week rest period. Doses were escalated when possible after the second course, and each patient was to receive six courses.
  
  
  RESULTS
  Only one partial response was observed. Although no patient had fatal bone marrow toxicity, only eight patients received the full six courses, primarily because of myelosuppression.
  
  
  CONCLUSIONS
  This schedule of oral idarubicin is relatively safe but produces fewer responses than are reported with the high-dose pulse regimens.
