||Occupational exposures and squamous cell carcinoma of the oral cavity, pharynx, larynx, and oesophagus: A case-control study in Sweden
||June 1998, Vol.55, No.6, p.393-400. 27 ref.
||This community-based case-referent study was initiated to investigate aetiological factors for squamous cell carcinoma of the upper gastrointestinal tract. The study was based on all Swedish men aged 40-79 living in two regions of Sweden during 1988-90. Exposure to asbestos was associated with an increased risk of laryngeal cancer, and a dose-response relation was present. The RR was 1.8 in the highest exposure group. More than eight years of exposure to welding fumes was associated with an increased risk of pharyngeal cancer (RR=2.3 (1.1 to 4.7)), and laryngeal cancer (RR=2.0). There were indications of a dose-response for duration of exposure. Associations were also found for high exposure to polycyclic aromatic hydrocarbons (PAHs) and oesophageal cancer (RR=1.9). Exposure to wood dust was associated with a decreased risk of cancer at the studied sites. The study indicates that welding may cause an increased risk of pharyngeal as well as laryngeal cancer. The findings corroborate an association between exposure to PAHs and oesophageal cancer.
