- First study (BRONC-ART) The purpose of this prospective study is to evaluate the 90-day morbidity and mortality rates of bronchial transplantation using cryopreserved aortic allograft in proximal lung cancer surgery. The investigators hypothesize that this stage 1-2 surgical innovation could be safe and effective in order to reduce the 90-day morbidity and mortality rates compared to those observed with pneumonectomy, especially when some factors are present: age > 70 years, right side, neoadjuvant chemoradiotherapy.
