Carcinogenesis of non small cell lung cancer and therapeutic implications

Abstract

The occurrence of a lung cancer is a consequence of a long-lasting process dealing with a transformation of a normal cell to a malignant one. The four steps of transformation reflect the genetic modifications of the cells. The molecular studies of pre-invasive lesions have already established a correlation between the lesion continuum and the multi-step carcinogenesis. Gradual genetic alterations are correlated with the increase of the cell&rsquo
