Bevezetés: A szerzők a Szabolcs-Szatmár-Bereg megyei leukémia/lymphoma regiszterben az elmúlt 35 év alatt (1983. január 1. és 2017. december 31. között) 4942 újonnan felismert, malignus hematológiai betegségben szenvedő, megyéjükben élő felnőtt beteg adatait rögzítették. A 4942 beteg között 640 akut myeloid leukémiás, 274 krónikus myeloid leukémiás, 287 polycythaemia verás, 378 essentialis thrombocythaemiás és 126 myelofibrosisos fordult elő. Célkitűzés: A regisztrált myeloid malignitásokban előfordult szolid tumorok ismertetése. Módszer: A leukémia/lymphoma regiszter társult tumorokra vonatkozó adatainak az elemzése. Eredmények: A 35 éves megfigyelési idő alatt 80 betegben, a myeloid malignitások 4,7%-ában fordult elő társult tumor, 23 akut myeloid leukémiás (3,6%), 18 krónikus myeloid leukémiás (6,6%), 16 polycythaemia verás (5,6%), 18 essentialis thrombocythaemiás (4,8%) és 5 myelofibrosisos (4,0%) betegben. Többes tumorok miatt a tumorok száma 84 volt. Huszonöt betegben a társult tumor a hematológiai malignitás felismerése után jelentkezett, 35-ben azt megelőzően, 20 beteg esetében a kétfajta malignitást egyidejűleg ismerték fel. Következtetések: A társult tumorok gyakorisága megyéjükben kissé elmarad az irodalomban ismertetett arányoktól. Az elemzett epidemiológiai adatok alapján több esetben ok-okozati összefüggés lehetősége merül fel a társulások létrejöttében.
