ABSTRACT
Background: Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic cells. The International Prognostic
Scoring System (IPSS) is the risk scale most employed in MDS. Cyclosporin A (CsA) has been used in the treatment of
cytopenias in MDS.
Objective: To evaluate hematologic response and identify response predictive factors in adults with MDS
treated with CsA.
Material and methods: Patients with MDS diagnosed according World Health Organization (WHO)
classification were recruited from January 1997 to June 2012. All patients were classified with IPSS, IPSS revised (IPSS-R),
WHO Prognostic Scoring System (WPSS), and WPSS revised (WPSS-R) risk scales. Cyclosporin A was administered orally
at a dose of 5 mg/kg/day. Hematologic response was evaluated following the International Working Group for MDS (2006
version) criteria.
Results: Inclusion criteria were met by 32 patients. Median age was 56.5 years, with a median follow-up of
3.1 years. Hematologic response was 56.2% and erythrocyte independence transfusion was found in 42.9% of patients. Age,
hemoglobin level, and WPSS at diagnosis were independent predictive factors for CsA response. Survival was longer in responder than in nonresponder CsA patients (p = 0.06).
Conclusions: Cyclosporin A induced hematologic response in
› 50% of patients with MDS aged ‹ 57 years, with Hb ‹ 8 g/dl and low WPSS at diagnosis.
