Multiple Primary Cancers Among Florida Male Career Firefighters
Menée à partir de données portant sur 290 624 hommes vivant en Floride, cette étude analyse le risque de cancers primitifs multiples chez les pompiers professionnels
Objective: There is limited information on the risk of multiple primary cancers (MPC) among firefighters. We evaluated the distribution and relative risk of MPC for male career-firefighters versus non-firefighters for the second, third, or fourth diagnosed cancers.
Methods: This population-based study employed linked data (1981-2014) from three sources in Florida to report the distribution and relative risk of MPC.
Results: There are 290,624 (20.81%) MPC (n = 1,054 career-firefighters, n = 289,570 non-firefighters). Firefighters have 1.14 times (95%CI:1.00-1.30; p = 0.047) greater number of MPC compared to non-firefighters. The distribution of MPC sites was relatively similar. Compared to non-firefighters, firefighters had a higher risk of melanoma of the skin, all melanomas for both the first and second MPC.
Conclusions: Future research is warranted to investigate melanoma risk as MPC and to identify associated occupational hazards. Firefighters face an increased risk for developing primary cancer due to their occupational exposure to select carcinogens. However, little is known about their developing additional multiple cancers. Florida cancer registry linked to firefighter certifications records shows statistically significantly higher expected number of multiple primary cancers among firefighters compared to non-firefighters.
