Purpose:
The importance of occupational exposures in patients with head and neck squamous cell carcinomas (HNSCC) has received little attention.
Methods:
In a single-center study, we prospectively characterized occupational exposures in 154 HNSCC cancer patients in a systematic occupational consultation and examined the association between most frequent exposures, HNSCC stage and localization.
Results:
Patients occupied a mean of 3.3 different positions during their working life. The prevalence of asbestos, the most frequent exposure (46 patients; 29.9%) was higher than in the French population > 50 years. Other frequent exposures were solvents (n = 26; 16.9%) and silica (n = 19; 12.3%). For 37 patients (24%) a possible link was identified between occupational exposures and HNSCC. Duration of asbestos exposure was significantly higher (p = 0.04) in patients with hypopharyngeal and laryngeal cancer compared to other localizations.
Conclusions:
Occupational exposures are frequent in patients with HNSCC and should receive increased attention by physicians.
Insights
Occupational exposures, including asbestos, solvents, and silica, are common in head and neck squamous cell carcinoma (HNSCC) patients. Physicians should pay more attention to these workplace risks.
Area of Science:
- Oncology
- Occupational Health
- Epidemiology
Background:
- Occupational exposures are increasingly recognized as potential contributors to various cancers.
- The role of workplace exposures in head and neck squamous cell carcinomas (HNSCC) has been historically under-investigated.
Purpose of the Study:
- To systematically characterize occupational exposures in patients diagnosed with HNSCC.
- To investigate the association between common occupational exposures and HNSCC characteristics such as stage and tumor location.
Main Methods:
- A prospective, single-center study involving 154 HNSCC patients.
- Detailed occupational history and consultation to identify workplace exposures.
- Statistical analysis to determine associations between exposures and HNSCC features.
Main Results:
- Patients reported an average of 3.3 occupations throughout their careers.
- Asbestos exposure was prevalent (29.9%), exceeding rates in the general French population over 50.
- Solvents (16.9%) and silica (12.3%) were also frequent exposures; 24% of patients had a potential occupational exposure link to HNSCC.
- Longer asbestos exposure duration correlated with hypopharyngeal and laryngeal cancer.
Conclusions:
- Occupational exposures are a significant factor in a notable percentage of HNSCC cases.
- Increased physician awareness and systematic evaluation of occupational history are crucial for HNSCC patients.
