Adjuvant radiation therapy in breast cancer: Recent advances & Indian data

Abstract

Breast cancer is the most common cancer among women in India, and adjuvant radiotherapy is an integral part of curative treatment in most patients. The recent decades have witnessed several advances in radiation therapy delivery. Several advances in radiation oncology have been identified which include technological advances, change in fractionation used, use of cardiac-sparing radiotherapy as well as efforts to personalize radiotherapy using accelerated partial breast irradiation or avoidance of radiotherapy in certain subpopulations. Indian data are available in most areas which have been summarized. However, increasing emphasis on research in these areas is needed so that effectiveness and safety in our setting can be established. Advances in breast cancer radiotherapy have resulted in improved outcomes. Data published from India suggest that these improved outcomes can be replicated in patients when appropriate treatment protocols are followed.
