BACKGROUND:
Asbestos exposure has been definitively
found to be associated with both
mesothelioma and lung cancer.
Nevertheless, in the overall population of
oil refinery workers potentially exposed
to asbestos, many studies clearly show a
definitely increased risk of mesothelioma,
but no proven excess of lung cancer after
comparison to the general population.
Through the presentation of new data and
the re-appraisal of two recent and
independent epidemiological studies
conducted in Liguria, Italy, and Ontario,
Canada, we attempt to shed light on this
apparently paradoxical finding. METHODS:
Lung cancer mortality was studied among
maintenance workers exposed to asbestos,
and among two other subgroups of refinery
employees: blue collar and white collar
workers. The comparison with blue collar
workers was performed in order to take
into account the role of healthy worker
effect, smoking habit, and the
socioeconomic level. The comparison with
white collar workers was performed to
control for other occupational lung
carcinogens. RESULTS AND CONCLUSIONS:
Results reveal a consistency between the
two studies and show that 96-100% of the
mesotheliomas and 42-49% of the lung
tumors arising among maintenance workers
were attributable to asbestos exposure.
Our new analysis, estimating two cases of
asbestos-related lung cancer for each case
of mesothelioma, confirms published
findings on the magnitude of
asbestos-related tumors in oil refineries.
