Incidence of cancer increases with the recent increase of the life expectancy. Aging is characterized by health status heterogeneity. It is therefore difficult to exactly predict tolerance to treatment and to make decision. One of the major question is to classify the problems on the base of their impact on health status and outcome. It is only possible if oncologists and geriatricians work together. The objectives at the national and international levels are the same: to develop formation (teaching programs), information (for professionals and the public), clinical research. It is more difficult to develop case management, because it depends on health organisation status. A strong global program has been developed in France with the emergence of Pilot Units for the coordination of Oncogeriatrics. It begins to produce results.
