Abstract: Introduction: In their previous works, the authors reported findings from familial hematologic malignancies in Szabolcs-Szatmár-Bereg county, Hungary. So far there are no other studies on this topic available in Hungary. Aim: Detailed analysis of epidemiologic features of hematologic malignancies of siblings. Method: During a 34-year period (between January 1, 1983 and December 31, 2016), 86 families with hematologic malignancies were recorded in Szabolcs-Szatmár-Bereg county. Among them, 19 cases of the affected siblings were registered. Results: In one family there were three sisters with polycythaemia vera, hence the number of analysed disease associations was 21. In all of the 21 cases, the younger sibling’s disease developed earlier. The average anteposition was 10.8 (1–33) years (median: 10 years). Conclusion: The anticipation was earlier observed in multigeneration hematological malignancies between direct and collateral descendants. On the basis of the above data, anteposition of the disease was observed in younger siblings. Orv Hetil. 2017; 158(33): 1283–1287.
