Personalized Oncology Meets Immunology: The Path toward Precision Immunotherapy.

UNLABELLED: Personalized oncology aims to tailor therapy by targeting the unique genetic characteristics of a patient's tumor, whereas cancer immunotherapy focuses on activating the patient's immune system to control the tumor. The fusion of these ostensibly separate strategies has created a new dimension for personalized cancer immunotherapy. This entails the development of next-generation cancer vaccines that target neoantigens as well as the use of mutational signatures as predictive biomarkers for clinical response. The optimal use of immunotherapeutic agents will hinge on a robust understanding of the mutational profile of a cancer's genome that significantly dictates antitumor immunity and immunotherapeutic response. SIGNIFICANCE: Cancer immunotherapy has provided substantial clinical benefit in a significant number of patients with advanced disease. However, the need for more precise immunotherapies and predictive biomarkers remains pressing. Recent progress in these areas has been promising and has created a framework for precision immune-oncology. Cancer Discov; 6(7); 703-13. ©2016 AACR. ©2016 American Association for Cancer Research.
