Implication

A retrospective population-based study observes rising essential thrombocythaemia incidence in an urban population, indicating expanded detection from routine automated platelet counts.

Key Points

To investigate long-term incidence trends over time for chronic Philadelphia chromosome-negative myeloproliferative disorders.
Conducted a retrospective population-based survey of diagnosed myeloproliferative disorders between 1983 and 1999 in Göteborg, Sweden.
Identified 416 confirmed cases, categorized as polycythaemia vera (N=205), essential thrombocythaemia (N=153), chronic idiopathic myelofibrosis (N=34), and unclassified disorders (N=24).
The annual incidence was 1.97 per 100,000 inhabitants for polycythaemia vera, 1.55 per 100,000 for essential thrombocythaemia, and 0.30 per 100,000 for chronic idiopathic myelofibrosis.
Annual incidence of essential thrombocythaemia increased significantly over time (P=0.008 overall; P=0.015 in males; P=0.118 in females), whereas incidence rates for polycythaemia vera and myelofibrosis remained stable.
