Abstract
BACKGROUND: Outdoor workers are occupationally exposed to significantly higher ultraviolet (UV) doses than the rest of the population. Recent data show a doubling of basal cell carcinoma (BCC) risk in outdoor workers with high occupational UV exposure. OBJECTIVES: To examine the stability and robustness of BCC risk estimators. METHODS: Sensitivity analyses to test model assumptions considering socioeconomic status, influence of matching procedure, gender and latency, regional differences (east/west), urban/rural cases/controls, and dual diagnoses (squamous cell carcinoma [SCC]/actinic keratoses grade III [AKIII]/Bowen disease [BD] and BCC) were performed. RESULTS: BCC risk was consistently higher for high occupationally UV-exposed individuals than for intermediate UV-exposed individuals, regardless of matching procedure, latency, regional differences (east/west), urban/rural recruitment of cases/controls, and dual diagnoses (SCC/AKIII/BD and BCC), sex, and socioeconomic status. CONCLUSION: The risk estimator for the association between exposure to solar UV radiation at work and the risk of developing BCC showed a high degree of stability and robustness for all variables investigated. The analyses support the recently published findings on the doubling of BCC risk in outdoor workers with high occupational UV exposure.
