opium and Multiple-Myeloma

The aim of this study was to estimate the association between organochlorine pesticides and polychlorinated biphenyls (PCBs) and multiple myeloma (MM).. 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.. 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 β-hexachlorocyclohexane (β-HCCH) were identified as significant independent predictors of MM.. Our study provides evidence that organochlorines contribute to the risk of MM.
