title: Incidence of chronic myeloproliferative disorders in the city of Göteborg, Sweden 1983-1992.
abstract: An estimation of the incidence of polycythaemia vera (PV), essential thrombocythaemia (ET) and chronic idiopathic myelofibrosis (CIM) in the city of Göteborg, Sweden during the period 1983-1992 was made from a retrospective case analysis of patients registered as chronic myeloproliferative disorders (CMPD) at the Departments of Medicine and the Department of Pathology of the two major hospitals in the city. A total of 125 cases of PV, 56 males and 69 females were identified. The number of cases as well as the age-specific incidence increased with age. The over all annual gender-specific incidence was 2.69 cases per 10(5) male inhabitants and 3.12 cases per 10(5) female inhabitants. The incidence of PV in relation to the European Standard Population was 2.02 cases per 10(5) inhabitants and year. There were 72 cases, 20 males and 52 females, with ET. The age-specific incidence was in all ages higher for females than for males and increased with age. The annual gender-specific incidence was 0.96 per 10(5) male inhabitants and 2.35 per 10(5) female inhabitants. The incidence of ET in relation to the European Standard Population was 1.28 per 10(5) persons and year. There were 20 cases of CIM, 11 males and 9 females. The annual gender-specific incidence of CIM was 0.53/10(5) male inhabitants and 0.41/10(5) female inhabitants. The incidence of CIM in relation to the European Standard Population was 0.31 per 10(5) persons and year. Seven persons, 2 males and 5 females, had a CMPD that could not be included in any of the above-mentioned groups, but were registered as CMPD, unclassified.
