Objective: The aim of this study was to estimate the association between organochlorine pesticides and polychlorinated biphenyls (PCBs) and multiple myeloma (MM). Methods: The risk of MM from organochlorine compounds was examined in a population-based case-control study in British Columbia, Canada. Congeners of PCBs and pesticides or pesticide metabolites were measured in plasma of 325 cases and 327 controls. Results: Most organochlorine analytes showed a significant association with MM. The strongest association (highest vs lowest quartile) was oxychlordane (odds ratio=7.44; 95% confidence interval=4.19 to 13.21). No heterogeneity was detected between organochlorines levels and MM subtypes. Only oxychlordane and b-hexachlorocyclohexane (b-HCCH) were identified as significant independent predictors of MM. Conclusion: Our study provides evidence that organochlorines contribute to the risk of MM.
