A retrospective stenting study on superior vena cava syndrome caused by lung cancer

Superior vena cava syndrome (SVCS) is a common condition predominantly caused by lung cancer. The presence of symptoms of SVCS, such as elevated intracranial pressure and laryngeal edema, indicates an unfavorable prognosis for lung cancer patients. Superior vena cava (SVC) stenting is the first-line treatment for SVCS. In this study, we retrospectively analyzed SVCS cases treated with stenting in our center to explore the safety and effectiveness of stenting in the treatment of SVCS.

We reviewed 16 patients with SVCS caused by lung cancer who were treated at our center with endovascular stenting between 2016 and 2018. Patient information such as age, sex, type of lung cancer, obstruction condition, complications, survival time, and postoperative treatments are summarized.

There were no treatment-related complications in the perioperative period in any of the patients. Examination at postoperative day 2 indicated that the accompanying SVCS symptoms had improved in all patients. The median survival of patients treated along with combined postoperative chemotherapy and antivascular targeted therapy reached seven months (1-18 months).

SVC stenting is effective as a first-line treatment modality for patients with SVCS caused by lung cancer. In combination with other treatment modalities, it can significantly alleviate symptoms and reduce complications, and thus it plays an important role in the treatment of patients with SVCS caused by lung cancer.
