Abstract

Abstract : Background: We previously reported a modest excess of cancer in World Trade Center (WTC)‐exposed firefighters versus the general population. This study aimed to separate the potential carcinogenic effects of firefighting and WTC exposure by comparing to a cohort of non‐WTC‐exposed firefighters. Methods: Relative rates (RRs) for all cancers combined and individual cancer subtypes from 9/11/2001 to 12/31/2009 were modeled using Poisson regression comparing 11, 457 WTC‐exposed firefighters to 8, 220 urban non‐WTC‐exposed firefighters. Results: Compared with non‐WTC‐exposed firefighters, there was no difference in the RR of all cancers combined for WTC‐exposed firefighters (RR = 0.96, 95%CI: 0.83–1.12). Thyroid cancer was significantly elevated (RR = 3.82, 95%CI: 1.07–20.81) from 2001 to 2009; this was attenuated (RR = 3.43, 95%CI: 0.94–18.94) and non‐significant when controlling for possible surveillance bias. Prostate cancer was elevated during the latter half (2005–2009; RR = 1.38, 95%CI: 1.01–1.88). Conclusions: Further follow‐up is needed to assess the relationship between WTC exposure and cancers with longer latency periods. Am. J. Ind. Med. 59:722–730, 2016. © 2016 Wiley Periodicals, Inc.
