Advancements in Interventional Oncology of the Chest: Transarterial Chemoembolization and Related Therapies

While embolization therapy has been used for many years in the treatment of nonmalignant diseases of the chest, such as pulmonary arteriovenous malformation treatment and bronchial artery embolization for hemorrhage, the application of transarterial techniques to the treatment of chest neoplasms is relatively uncommon. Extrapolating from transarterial chemoembolization techniques used for liver malignancy, investigators have recently sought to expand the indications for transarterial techniques from the control of symptoms such as bleeding to the control of disease progression and potentially survival benefit in patients with malignancies in the chest. This article provides an overview of the current embolotherapy techniques used in the treatment of patients with thoracic malignancies.
