[Contributions of the descriptive epidemiology, the registers and the troops. French situation seen by the registers of population].

This article describes the situation of the cancer at the elderly in France from a synthesis of various studies carried out by the French network of the registers of cancer, only source of information which is not soiled on the bias by selection. The cancer is especially a pathology of the old subject, 47 % of the cases of cancers arise at people's of more 70 years, 30 % beyond 75 years and 14 % at the people of more than 80 years. This proportion is 42 % at the women of more 70 years, 30 % beyond 75 years and 17 % at the women of more than 80 years. The forecast of these patients degrades with the age. The bad forecast of the old subjects is often associated, and sometimes totally owed, with a strong initial mortality which can be connected either to the initial gravity of the disease, or in the coverage which is less aggressive at the same moment for the old subjects and more selective. double dagger.
