The role of radiotherapy in the management of nodal disease in breast cancer.

The management of nodal disease in breast cancer has evolved over the last two decades. With minimalist surgical approaches for early breast cancers becoming commonplace, the question of whether radiation can replace surgery to reduce morbidity is an important question in this population, as decision making has become more complex. In more advanced disease, and in patients with significant high-risk clinical and/or pathological features, the dilemma of who should receive regional nodal irradiation has been addressed in large studies but remains controversial. In this article, we summarise and discuss the recent trials which guide modern clinical practice, as well as some of the ongoing studies which aim to address outstanding questions within the field.
