Stereotactic Margins in Localized Bronchial Cancer (T1/T2a, N0)

University Hospital, Strasbourg, France300 enrolled

Overview

Bronchopulmonary cancer is the first cause of mortality in the world. We want to update the margins used in stereotactic radiotherapy, in the context of localized lung cancer, of non-surgical management. The investigators wish to redefine the stereotactic radiotherapy margins according to the histological type in localized non-small cell lung cancer. Indeed, these criteria were previously defined on a smaller cohort, in the context of 3D radiotherapy (mainly T3, T4 tumors). In addition, the incidence of radiation pneumonitis is highly dependent on the irradiated lung volume, which in turn depends on the CTV margins used.
