Description

Savona et al listed criteria for progression of myelodysplasia/myeloproliferative neoplasms (MDS/MPN) in adults. The authors are from multiple institutions from around the world participating in the MDS/MPN International Working Group.


Patient selection: MDS/MPN

 

Major criteria:

(1) increase in blast count in the bone marrow (see below)

(2) evidence of cytogenetic evolution (appearance of a new or previously present abnormality after complete cytogenetic remission, using FISH or karyotyping)

(3) new extramedullary disease (new or worsening splenomegaly, hepatomegaly, granulocytic sarcoma, skin lesions, etc)

 

Minor criteria:

(1) transfusion dependence

(2) increasing symptoms (>= 50% increase in MPN-SAF TSSII)

(3) molecular evidence of clonal evolution with increased mutational burden

(4) significant loss of maximal response on cytopenias (>= 50% decrease from maximum response in granulocytes or platelets)

(5) reduction in hemoglobin by >= 1.5 g/dL from baseline or best response

 

Diagnosis of progression - one or more of the following:

(1) >= 2 major criteria

(2) 1 major and >=2 minor criteria

(3) >= 3 minor criteria
