[Molecular epidemiology of the lung cancer]. / Épidémiologie moléculaire du cancer bronchique.

ABSTRACT

Lung cancers are common malignancies, which have a very poor prognosis. These are the leading cause of cancer deaths in France and worldwide. Behind this unfavourable prognosis hides many disparities according to age, sex, social level and exposure to risk factors. The detection of the genetic abnormalities, which drive carcinogenesis has totally changed the therapeutic approach. Tumours are now classified according to their molecular profile which is itself associated with new demographic data. We here review the most recent data on this topic.
