title: Sequential treatment of superior vena cava syndrome caused by of non-small cell carcinoma lung cancer (NSCLC) with vascular stenting and iodine-125 implantation.
abstract: Feasibility and efficacy of sequentially performed endovascular stenting and Iodine-125 brachytherapy for malignant superior vena cava syndrome (SVCS) were evaluated. Thirty-four patients with malignant SVCS caused by NSCLC underwent sequential treatment of endovascular stenting and Iodine-125 brachytherapy. SVCS was diagnosed in all patients by CT images or vena-cavography. Pathology diagnosis was acquired by image guided biopsy. Endovascular stent placement was performed as first-line treatment for symptom relief. CT-guided Iodine-125 seed implantation performed 24hr after stenting. Clinical end points were resolution of symptoms and local efficacy of primary malignancy regression. Symptom relief rate was >90% after 24hr and 97% after 3 months. No migration of seeds or restenosis occurred in any patient. The local efficacy (defined as either partial or complete response) was 53%, 79%, 88% and 74% after 1, 3, 6 and 12 months, respectively. Mean SVCS-free survival time was 305 days (range 120-960 days). Two patients were still alive at the time of this writing, Thirty-one died from progression and one died from acute heart disease. Sequentially performed endovascular stenting and Iodine-125 brachytherapy provides a safe and effective alternative for malignant SVCS caused by NSCLC.
