Brachytherapy in the treatment of breast cancer

Abstract

Brachytherapy is an important radio-therapeutic modality for a variety of malignancies, including prostate cancer, cervix cancer, breast cancer, vagina cancer, endometrium cancer, head and neck cancer, and many more. This technique has been shown to be an effective and safe non-pharmaceutical treatment with fewer serious complications and better outcome than other treatments for breast cancer. Every year, hundreds of thousands of patients around the world benefit from brachytherapy, which reliably delivers a relatively higher radiation dose to the intended target. However, the follow-up time, patient eligibility criteria, treatment strategy, and radiation doses used in published studies are somewhat inconsistent, making it difficult to strictly compare and evaluate the performance of the treatment. More rigorous studies are required to confirm the safety of this technique and to make outcome data more comparable. In this review, we focus on recent advances in breast brachytherapy techniques and provide an overview of outcomes, cosmetic outcome, toxicity, complications, and limitations of brachytherapy for the treatment of breast cancer. We also summarize the clinical outcomes and toxicity results in patients receiving or not receiving brachytherapy.
