Abstract
Background: Environmental exposure to trichloroethylene (TCE), a carcinogenic dry‐cleaning chemical, may be linked to Parkinson's disease (PD). Objective: The objective of this study was to determine whether PD and cancer were elevated among attorneys who worked near a contaminated site. Methods: We surveyed and evaluated attorneys with possible exposure and assessed a comparison group. Results: Seventy‐nine of 82 attorneys (96.3%; mean [SD] age: 69.5 [11.4] years; 89.9% men) completed at least one phase of the study. For comparison, 75 lawyers (64.9 [10.2] years; 65.3% men) underwent clinical evaluations. Four (5.1%) of them who worked near the polluted site reported PD, more than expected based on age and sex (1.7%; P = 0.01) but not significantly higher than the comparison group (n = 1 [1.3%]; P = 0.37). Fifteen (19.0%), compared to four in the comparison group (5.3%; P = 0.049), had a TCE‐related cancer. Conclusions: In a retrospective study, diagnoses of PD and TCE‐related cancers appeared to be elevated among attorneys who worked next to a contaminated dry‐cleaning site. © 2024 The Authors.
