Increased frequency of hematopoietic malignancies in relatives of patients with lymphoid neoplasms: a French case-control study.

Abstract : Lymphoid neoplasms (LNs), including non-Hodgkin's lymphoma (NHL), Hodgkin's lymphoma (HL), lymphoproliferative syndrome (LPS) and multiple myeloma (MM), are among the most frequent cancers ( approximately 17,000 new cases per year in France), after those related to smoking. LNs were investigated using the data from the ENGELA study. ENGELA is a multicenter hospital-based case-control study that was carried out in France over the period September 2000-December 2004. In all, 822 cases (397 NHL, 149 LH, 168 SLP and 108 MM) and 752 controls were included and described 5,481 and 5,188 first-degree relatives, respectively. A positive association with a familial history of hematopoietic cancer was observed for LN (OR = 1.7 [1.0-2.8]) overall and for LPS (OR = 3.2 [1.4-6.8]). The associations with HL (OR = 10.4 [2.0-53.8]) and NHL (OR = 2.4 [1.0-5.9]) were stronger for men. The associations were also stronger when the disease had been diagnosed before the relatives were aged 45 years. The results mainly support the involvement of genetic factors and suggest that at least some of those factors may be sex-linked. However, the slight overrepresentation of affected spouses among the cases might also support the responsibility of environmental factors.
