Stereotactic body radiotherapy for superior vena cava syndrome

Abstract

Tumor-related superior vena cava syndrome (SVCS) is characterized by the syndrome in which the superior vena cava is blocked by the tumor of the right upper lobe of the lung or the lymph nodes in the 4R region of the mediastinum. As the first diagnosis symptom, SVCS occurs in about 1.7% non-small cell lung cancer cases (NSCLC) [1]. Stereotactic body radiotherapy (SBRT)T has been gradually tried for SVCS [2], but limited to small lesions with a diameter of less than 5 cm. We successfully applied SBRT in the treatment of SVCS due to compression of a large lung squamous cell carcinoma and 4R lymph nodes
