Essential thrombocythemias. Clinical evolutionary and biological data

Area of Science:

• Hematology
• Oncology

Background:

• Thrombocythemia is a condition characterized by elevated platelet counts.
• Understanding its clinical manifestations and long-term outcomes is crucial for patient management.

Purpose of the Study:

• To analyze the clinical features, complications, and survival of patients with thrombocythemia.
• To identify factors associated with hemorrhagic and thrombotic events.

Main Methods:

• Retrospective review of 94 patients diagnosed with thrombocythemia.
• Analysis of patient demographics, platelet counts, clinical manifestations (hemorrhage, thrombosis), and treatment outcomes.

Main Results:

• Hemorrhagic manifestations occurred in 45% of patients, while 29% experienced thrombotic complications.
• Hemorrhages were more frequent with platelet counts exceeding 1000 X 10(9)/1.
• Platelet hypoaggregation was observed in 94% of cases.
• Long-term survival was favorable, with 80% survival at 100 months.
• Five patients transformed into acute leukemia.

Conclusions:

• Thrombocythemia management requires a conservative approach due to its prolonged course.
• Anti-aggregating drugs and non-alkylating chemotherapy agents are suggested therapeutic options.
• Further research may elucidate specific risk factors for thrombotic events.
