Acute leukemia as a transformation after polycythemia vera

Area of Science:

• Hematology
• Oncology

Background:

• Polycythemia vera (PV) is a myeloproliferative neoplasm.
• Transformation to acute leukemia is a rare but serious complication of PV.

Observation:

• A patient diagnosed with polycythemia vera developed acute leukemia within one month.
• Treatment for PV consisted solely of phlebotomy on three occasions.
• The patient exhibited an initial brief response to vincristine and prednisone.

Findings:

• Leukemic phase showed no chromosomal abnormalities.
• Terminal deoxynucleotidyl transferase (TdT) was positive in the leukemic phase.
• Rapid progression from PV to acute leukemia was observed.

Implications:

• This case underscores the potential for very rapid leukemic transformation in PV.
• Further research into early detection and management of PV transformation is warranted.
• Understanding rare but aggressive disease progressions is crucial for patient outcomes.
