RT Journal Article SR Electronic T1 Imaging approaches and radiomics: toward a new era of ultraprecision radioimmunotherapy? JF Journal for ImmunoTherapy of Cancer JO J Immunother Cancer FD BMJ Publishing Group Ltd SP e004848 DO 10.1136/jitc-2022-004848 VO 10 IS 7 A1 Roger Sun A1 Théophraste Henry A1 Adrien Laville A1 Alexandre Carré A1 Anthony Hamaoui A1 Sophie Bockel A1 Ines Chaffai A1 Antonin Levy A1 Cyrus Chargari A1 Charlotte Robert A1 Eric Deutsch YR 2022 UL http://jitc.bmj.com/content/10/7/e004848.abstract AB Strong rationale and a growing number of preclinical and clinical studies support combining radiotherapy and immunotherapy to improve patient outcomes. However, several critical questions remain, such as the identification of patients who will benefit from immunotherapy and the identification of the best modalities of treatment to optimize patient response. Imaging biomarkers and radiomics have recently emerged as promising tools for the non-invasive assessment of the whole disease of the patient, allowing comprehensive analysis of the tumor microenvironment, the spatial heterogeneity of the disease and its temporal changes. This review presents the potential applications of medical imaging and the challenges to address, in order to help clinicians choose the optimal modalities of both radiotherapy and immunotherapy, to predict patient’s outcomes and to assess response to these promising combinations.
