Leukemia Incidence by Occupation and Industry: A Cohort Study of 2.3 Million Workers from Ontario, Canada.

July 2024
Although a significant body of evidence has attributed certain occupational exposures with leukemia, such as benzene, formaldehyde, 1,3-butadiene and ionizing radiation, more research is needed to identify work environments at increased risk for this disease. Our study aimed to identify occupational and industry groups associated with an elevated incidence of leukemia using a diverse cohort of workers' compensation claimants from Ontario, Canada. A total of 2,363,818 workers in the Occupational Disease Surveillance System (ODSS) cohort, with claims between 1983-2019, were followed for malignant leukemia diagnoses up to 31 December 2019.

- The study aimed to explore cancer risk in Ontario's workforce by comparing cancer rates using both internal (ODSS workers) and external (general population) reference groups.
- Researchers analyzed data from about 2.3 million workers with compensation claims to calculate standardized incidence ratios (SIRs) for various cancer types from 1983 to 2018.
- Results showed that SIRs were usually similar or lower when compared to the general population, revealing differences in cancer rates depending on the reference group used, highlighting the significance of reference group selection in occupational cancer risk evaluations.
Background: The relation between breast cancer molecular subtype and survival has been studied in several jurisdictions, but limited information is available for Ontario. The aim of this study was to determine breast cancer survival by molecular subtype and to assess the effect on survival of selected demographic and tumour-based characteristics.
Methods: We extracted 29 833 breast cancer cases (in 26 538 girls and women aged ≥ 15 yr) diagnosed between 2010 and 2012 from the Ontario Cancer Registry.
