Research outcomes are various medical, economic and ethic. Medical because decision-making will be improved with simplified geriatric assessment; economic because a better knowledge of geriatric assessment will improve treatment toxicity prevention and decrease treatment costs. Ethic will be associated with this project because a better knowledge of geriatric assessment tools to predict survival and tolerance treatment could improve the choice of best supportive care if prognosis markers are not favorable to active therapy. This project could induce important modification of practice in this area to an improved personalized treatment and simplification of geriatric assessment allowing a large diffusion in hospitals and clinics.
