Palliative radiation therapy for locally advanced breast cancer.

Abstract

Purpose of review: Globally, breast cancer is the most commonly diagnosed cancer in women. Locally advanced breast cancers (LABCs) may necessitate palliative radiation therapy (RT) due to the severity of the patients' symptoms, inoperability, or other reasons precluding curative-intent treatment such as poor performance status and patient comorbidities. This review aims to discuss current evidence on palliative RT in LABC.

Recent findings: Advanced targeted RT techniques have led to improvements in local control with reduced treatment-related toxicities. Emerging short-course palliative RT prescriptions offer feasible options that avoid delay in systemic therapy. Additionally, recent studies also highlight approaches for integrating palliative RT with systemic therapies.

Summary: Palliative RT plays a vital role in managing symptoms and enhancing quality of life for LABC patients. However, there is currently no consensus on the optimal prescriptions for palliative RT in these patients. Standardized reporting of palliative RT studies is needed for robust comparison of efficacy and toxicity between various treatment regimens. Furthermore, future research on the optimal integration of RT with novel systemic agents is needed.
