Interventional oncology procedures for breast cancer metastatic disease: current role and clinical applications.

Worldwide, breast cancer constitutes the most common malignant neoplasm among females, impacting 2.1 million women annually. Interventional oncology techniques have been recently added as an additional therapeutic and palliative alternative in breast cancer metastatic disease, concerning mainly osseous, liver, and lung metastasis. In the current literature, there are reports of promising results and documented efficacy regarding the ablation of liver and lung metastasis from breast carcinoma, transarterial embolization or radioembolization, as well as the treatment of osseous metastatic disease. These literature studies are limited by the heterogeneity of breast cancer disease, the evaluation of variable different parameters, as well as the retrospective nature in most of the cases. Consequently, dedicated prospective series and randomized studies are required to identify the role of minimally invasive local therapies of interventional oncology armamentarium. The present review paper focuses upon the current role of interventional oncology techniques for the curative or palliative treatment of metastatic breast cancer disease. The purpose of this review paper is to present the current minimally invasive procedures in the treatment of metastatic breast disease, including local control rates and survival rates.
