Abstract

Introduction: During a 36-year period (between January 1, 1983 and December 31, 2018), 5159 adult patients with newly diagnosed haematological malignancy were registered in the leukaemia/lymphoma registry of Szabolcs-Szatmár-Bereg county.

Aim: The review of the incidence of different haematological malignancy in the authors' county, and the changes of incidence from time to time, the associated haematological malignancies, and familial occurrence of malignant haematological diseases.

Method: Detailed analysis of the data of the registry, with statistical analysis of incidence.

Results: The incidence of Hodgkin disease and non-Hodgkin's lymphoma (1.49 and 7.12 new cases, respectively/100 000 inhabitants/year) was a little smaller, that of essential thrombocythaemia was larger than in the published data. The incidence of all other haematological malignancies corresponded to the data of the literature. The change of incidence of all malignant haematological diseases was similar to the published data. In the registry, there were 35 patients with two different malignant haematological diseases appearing simultaneously or successively. During the 36-year period, 88 families with haematological malignancies were recorded in the registry.

Conclusion: With the exception of Hodgkin disease, non-Hodgkin's lymphoma, and essential thrombocythaemia, the incidence of other haematological malignancies corresponded to the data of the literature. The change of incidence in all entities was similar to that observed by other authors. The authors in their country do not know other published data related to associated malignant haematological diseases. The observed anteposition in familial haematological diseases of uncle/aunt and nephew/cousin, and anteposition in malignant haematological diseases of siblings are equally new in the literature.
