PP01.61 (Poster) The Use of Low-Dose Lung CT for Lung Cancer Screening in Firefighters

Pdf Summary

This study evaluated the use of low-dose lung CT for lung cancer screening in firefighters aged 40 and above who were eligible to receive screening as part of FEMA Assistance for Firefighters Grant funding. Over a three-year span, 97.5% of the 635 firefighters received low-dose lung CT. The average age was 49 years, and the average years of service was 21 years, with 94% of the firefighters being male. Among the firefighters, 254 lung nodules were identified, with 5.91% of lesions measuring 8mm in size. The majority of lung lesion classifications were LungRADS 1 (62.5%) and LungRADS 2 (31.3%), with fewer cases of LungRADS 3 (4.4%) and LungRADS 4 (1.8%). Additional findings included a mediastinal seminoma, thyroid nodules requiring further work-up (including a diagnosis of medullary thyroid carcinoma and papillary thyroid carcinoma), and non-Hodgkin's lymphoma. Varying degrees of coronary artery disease were also detected. The study concludes that low-dose lung CT is valuable for screening firefighters, who often require earlier and more frequent screening due to their higher risk of lung cancer. The authors emphasize the need for guidelines specifically tailored to firefighters and further research on occupational exposures to carcinogens and their impact on cancer development.
