Chromosomal changes are linked to polycythemia vera transformation. Advanced polycythemia vera showed chromosomal aberrations, particularly when evolving into other myeloproliferative diseases.

Area of Science:

  • Hematology
  • Cytogenetics
  • Oncology

Background:

  • Polycythemia vera is a myeloproliferative neoplasm.
  • Chromosomal abnormalities are observed in myeloproliferative neoplasms.
  • The role of cytogenetic changes in disease progression requires further investigation.

Purpose of the Study:

  • To investigate the frequency and significance of chromosomal changes in patients with polycythemia vera.
  • To explore the association between cytogenetic aberrations and disease transformation.
  • To determine if myelosuppressive therapies correlate with cytogenetic alterations.

Main Methods:

  • Cytogenetic examination of 54 patients diagnosed with polycythemia vera.
  • Analysis of chromosomal changes in patients during the advanced phase of the disease.

  • Examination of chromosomal aberrations in patients whose polycythemia vera transformed into other myeloproliferative diseases.

    • Main Results:

    • 17.6% of patients in the advanced phase exhibited chromosomal changes.
    • 65% of patients with disease transformation showed chromosomal aberrations.
    • The 20q- chromosomal change, common in polycythemia vera, was only found in transformed cases.

    Conclusions:

    • Chromosomal aberrations are associated with the transformation of polycythemia vera into other myeloproliferative diseases.
    • The number of chromosomal changes may correlate with disease progression.
    • No link was found between cytogenetic changes and myelosuppressive treatments in this study.
