title: Colorectal cancer incidence in pattern and model makers: evidence from a screening program.
abstract: This study is designed to evaluate the efficacy of colorectal cancer screening in a high risk population of pattern and model makers. The cohort of 1,641 white male automotive pattern and model makers was identified in 1981, and offered colorectal cancer screening. The program involved periodic 60 cm flexible sigmoid examination, stool occult blood testing, and digital rectal examination. Screening was offered in 1981, 1982, 1985, 1988, and 1991. Approximately 60% of those eligible participated in at least one screening examination. Nonparticipants showed a relative risk for incident colorectal cancer of over 10, compared to those who participated at least once in the screening. Cohort tracking has accumulated 10 years; results suggest a benefit to colorectal cancer screening in this population.
