Multiple myeloma and family history of lymphohaematopoietic cancers: Results from the International Multiple Myeloma Consortium

MM risk was elevated in association with having a first-degree relative with any lympho-haematapoietic cancer (Odds Ratio (OR) = 1·29, 95% Confidence Interval (CI): 1·08–1·55). The association was particularly strong for having a first-degree relative with MM (OR = 1·90, 95% CI: 1·26–2·87), especially among men (OR = 4·13, 95% CI: 2·17–7·85) and African Americans (OR = 5·52, 95% CI: 1·87–16·27).These results support the hypothesis that genetic inheritance plays a role in MM aetiology. Future studies are warranted to characterize interactions of genetic markers with environmental exposures
