Cancer mortality in Île-de-France and its territories-40 years of evolution

The leading cause of death in Île-de-France, cancers caused 20,866 deaths in 2022, almost one in four, 27 % in men and 24 % in women. Over the 1979-2022 period, cancer mortality was constantly decreasing thanks in particular to progress made in terms of treatment, diagnosis and care.

More than 40 % of cancers could be avoided by primary prevention actions. The new ten-year 2021-2030 cancer strategy thus makes prevention one of its priorities. She also insists on the fight against cancers of bad prognosis, such as lung or pancreatic cancers. It was available in regional roadmaps for better adaptation to territorial issues.

The study carried out by the ORS Île-de-France presents updated and territorialized data on cancer mortality in Île-de-France and for 20 of its locations, with a retrospective look over the last 40 years.

Among the essential elements, we will remember that:

• Between 1979 and 2022, cancer mortality fell strongly in Île-de-France, in men as in women, in all departments, for almost all cancer locations, and at a more sustained rate than in the ‘Together of France. Since 2018, Île-de-France has been the most preserved region of cancer mortality;

• Cancer mortality linked to tobacco or alcohol consumption, more specifically impacting men, has experienced a significant fall in men in Île-de-France;

• Among the Ile -de -France, two cancers are experiencing an unfavorable development, the pancreas and the lung. The mortality rate by lung cancer has doubled in 44 years in Île-de-France, with significant excess mortality in Paris;

• Territorial disparities: already observed in previous years, an excess of mortality from regional level is found for men and women in Seine-et-Marne and in Val-d’Oise, as well as in most of their intermunicipalities; Conversely, Paris and Hauts-de-Seine have an under-mortality for men and Seine-Saint-Denis for women;

• In men, cancer mortality tends to increase with the level of social disadvantage. Among women, an inverted social gradient is found for lung cancer, between Paris (on mortality) and Seine-Saint-Denis (under-mortality).

• Two favorable developments to remember: the beginning of decrease in mortality by lung cancer among Ile-de-France, which is even more visible for premature mortality, and a significant improvement in the situation in Seine-Saint-Denis which displays in 2022 one of the rates of lowest mortality in the region.
