Mediastinal Lymph Node Recurrence From All Types of Primary Cancer

Phase II multicenter trial evaluating the safety, tolerability, and feasibility of MRI-guided stereotactic radiotherapy using MRI-LINAC in patients with ultracentral lung tumors or lymphadenopathy in the context of controlled oligometastatic disease. The study investigates the potential of this innovative technology, which enables real-time treatment adaptation, with the goal of optimizing the benefit-risk ratio in a population at high risk of radiotherapy-related toxicity
