Key clinical point: Cumulative airborne dioxin exposure is significantly associated with an increased risk for non-Hodgkin's lymphoma (NHL), particularly for combined chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).
Major finding: A significant association was observed between log-transformed cumulative dioxin exposure index scores and the risk for NHL (adjusted odds ratio [aOR] 1.2; 95% CI 1.0-1.4), especially in case of the CLL and SLL subtypes (aOR 1.6; 95% CI 1.1-2.3), for a 4.4 log µg-toxic equivalent quantity/m2 increase corresponding to a standard deviation.
Study details: This case-control study was nested within the prospective French National Institute for Health and Medical Research E3N cohort and included 368 women with NHL and 368 matched control women without NHL.
Disclosures: The E3N cohort was established and maintained with the support of the Mutuelle Générale de l'Education Nationale, France, and other sources. The authors declared no conflicts of interest.
