[Clinical research in radiation oncology].

Clinical research is summarizing scientific trials performed in human aiming to improve biological and medical knowledges. The management of such an activity has to be conducted in a secured environment in terms of expertise, competency and professionalism of involved actors. In the field of cancer, multidisciplinarity is key in the treatment of malignant disease and plays a major role sequentially or concomitantly. In the 90s, clinical research in radiation oncology obtained historical successes, which remain validated guidelines for national societies in a significant number of clinical situations. They concern not only technological improvements but also combined modality treatments with chemotherapy, hormonal therapy and potentially new targeted agents. Radiotherapy, in a palliative or in a curative setting, benefited from dramatic technological improvements aiming to address patient quality of life after radiation therapy. Actually, the emergence of artificial intelligence is willing to modify our current practice historically based on old concepts of clinical evaluation.
