Lung Microcytoma Extensive Disease: Prospective Study of Association of Thoraco-mediastinal Radiotherapy With Maintenance Immunotherapy Treatment With Atezolizumab
Investigate the role of consolidative radiotherapy treatment at the thoraco-mediastinal level in the patient suffering from lung microcytoma - extensive disease and treated with chemo-immunotherapy with atezolizumab, in association with maintenance therapy with atezolizumab.

• Initial staging and restaging after chemo-immunotherapy with CT, CT-PET FDG and brain MRI;
• In at least partial response (defined according to the Recist criteria \[18\]) after treatment chemoimmunotherapy according to the Impower 133 scheme;
• Haematological, respiratory toxicity ≤ G1, other toxicities ≤ G2 at the time of treatment radiotherapy;
• Pulmonary function tests at the time of radiotherapy treatment compatible with irradiation: FEV≥1.2 l or \>40%, DLCO≥50%;
