Radiotherapy for lung tumors arising after a prior pneumonectomy

Treatment of patients with lung tumors in the contralateral lung after a prior pneumonectomy is challenging, especially for centrally located lesions. The curative modalities have included surgery, cryoablation, radiofrequency ablation, and radiotherapy (1-5). Unfortunately, available data on curative treatment of lung tumors after pneumonectomy by these modalities are limited to small series and case reports, and the safety and efficacy of these modalities remained unclear (1-5).
