Brief summary
The poor prognosis in the early-stage of lung cancer is due to potential worsening of the disease (local relapse, metastasis), to insufficient efficacy and toxicity of actual treatments. FDG-PET is a medical imaging modality allowing the quantification of the tumour glucose consumption. Then, this exam is used for pathology staging, target volume definition for RT, and treatment efficiency few months after RT or CRT. Our assumption is that an FDG-PET exam during the course of the RT or CRT might be predictive of the treatment efficiency few months later. In this study, the investigators propose to perform 4 FDG-PET: first PET1 before radiotherapy, second PET2 during the radiotherapy (see RTEP1), third and fourth PET3 PET4 3month and 12 month after the therapy. The investigators will investigate the performances of FDG-PET performed during the RT or CRT for the prediction of the one-year patient heath outcome. If the predictive value of TEP2 is confirmed, the investigators would be able to optimize the planning treatment during the course of the therapy.
