[Innovation in radiotherapy: A glance at 2018]

Abstract

Innovation in radiotherapy should meet multiple challenges, both technically, biologically, clinically and socially. Scientific, technological and biological advances have resulted in major changes in the implementation, indications, and therapeutic index of radiotherapy over the last century. Based on technical innovations (conformal radiotherapy, intensity modulation, CBCT, stereotactic body radiotherapy and MRI embedded system) and knowledge in cancer biology ("oxygen effect", "checkpoints", targeted therapies, molecular profiles and immunotherapy) highlighted in recent decades, the news in radiotherapy is rich and varied. The 2018 news are particularly focused in the role of hypofractionation in prostate cancer, the use of stereotactic body radiotherapy in oligometastatic patients, the possibility of de-intensify treatment in HPV-related oropharynx cancer, and the combination of short-term androgen deprivation to prostate bed salvage radiotherapy. The present manuscript reviews the 2018 latest advances.
