[Epidemiologic features of myeloma in Szabolcs-Szatmár-Bereg county, Hungary. Analysis of data of a 33-year period].

INTRODUCTION

In their previous work, the authors reported findings from 30 years on the incidence of hematological malignancies in Szabolcs-Szatmár-Bereg county, Hungary. Until now there are no other studies on this topic available in Hungary.

AIM: Detailed analysis of epidemiologic features of patients with myeloma.

METHOD: During a 33-year period (between January 1, 1983 and December 31, 2015) 4521 adult patients with hematologic malignancies were recorded in the leukaemia/lymphoma registry of Szabolcs-Szatmár-Bereg county. Among them 440 patients with myeloma (9.73%) were registered (397 multiple myeloma, 38 solitary, bone/soft tissue plasmocytoma, 5 primary plasma cell leukaemia).

RESULTS

The incidence of myeloma in Szabolcs-Szatmár-Bereg county showed an increasing tendency, with an overall incidence rate of 2.33/100 000 inhabitants/year. The male:female ratio was 45.9%:54.1%, the average age of patients was 65.1 (28-90) years, and 59.4% of the patients with multiple myeloma had IgG-type monoclonal immunoglobulin. There was no town or village in this county where the occurrence of patients with myeloma in one thousand inhabitants was significantly higher, than the average (0.78).

CONCLUSIONS

The epidemiologic features of myeloma in Szabolcs-Szatmár-Bereg county - except a moderate female dominance - is essentially similar to data published in the literature. Orv. Hetil., 2016, 157(34), 1357-1360.
