Lung cancer, mortality reduced by a half with spiral TC scan screening
A study conducted by epidemiologist Fabio Barbone, oncologist Gianpiero Fasola and additional nine experts, published in the International Journal of Epidemiology of the Oxford University Press, showed that it is possible to reduce mortality due to lung cancer by a half.
The results of the study carried out by the 11 researchers, mainly from the University of Udine and the Udine Integrated University Health Unit, are considered to be globally important: these results show spiral TC scan screening, as compared to monitoring performed by chest X-ray, it is possible to identify cancer at an early stage and reduce mortality in subjects exposed to asbestos by a half.
“This is a result that the international public healthcare system has been expecting for some time and it was achieved thanks to a patient team work which lasted about 15 years”, said professor Barbone, the first study author.
Moving from a study started in 2002 and published in 2008 by Gianpiero Fasola on the efficacy of low dose CT scan screening, the new study aimed at establishing if following this analysis the observed mortality of subjects undergoing the screening would be lower.
By comparing the mortality of subjects participating in the 2002 study to a sample of subjects who had not participated in the study, the researchers discovered that mortality due to lung cancer in the first group was reduced by 59% as compared to the subjects in the second group.
This is the first international study to show this evidence in subjects exposed to asbestos: according to Fasola, it is now important to evaluate how to use this data in public programmes of prevention addressed to sensitive subjects.
