A retrospective cohort study of lung cancer incidence in nylon flock workers, 1998-2008.

During an investigation of a novel interstitial lung disease in a cohort of nylon flock workers, a former worker was found to have developed bilateral synchronous pulmonary adenocarcinomas three decades after he quit smoking, suggesting that exposures in this industry might pose excessive risk of lung cancer. We conducted a retrospective cohort study of lung cancer incidence in the original study cohort (n=162) from August 15, 1998, to August 14, 2008. The Rhode Island Cancer Registry identified cohort members with lung cancer and provided age-gender-era-specific rates of lung cancer in Rhode Island.
