Cancer Incidence and Mortality in the Oldest Old: A Nationwide Study in Finland.

ABSTRACT: The world's population is aging rapidly. This study reports the burden of cancer in the "oldest old" (aged ≥85 years) in Finland, 1953-2017, and estimates age-specific cancer rates in the older population (65-99 years) for 1988-2017. The Finnish Cancer Registry provided data on all cancer diagnoses, cancer deaths, and other deaths in cancer patients in Finland for 1953-2017. Between 1953-1957 and 2013-2017, the proportion of incident cancers in those aged ≥85 years increased from 1.5% to 9.6% (597 to 15,360 new cases), and in 2013-2017, more new cancers were diagnosed at ages ≥85 years than ages <50 years. Cancer incidence and excess mortality attributable to cancer peaked at ages 85-94 years and declined subsequently, whereas cancer-specific mortality continued to increase or plateaued. D
