Abstract Cancer in the oldest old is a novel problem, due to the recent burgeoning of the population aged 85 and older. This article addresses three critical questions related to cancer in the oldest old: Does the incidence of cancer increase after age 95? Is cancer a common cause of death for the oldest old? Is cancer accurately diagnosed in the oldest old? The authors analyzed a group of 507 autopsies of elderly, divided in three age groups, 75 90 years, 95 99, and over 99 (centenarians). The prevalence of cancer was 35\% among the younger persons and 20\% and 16\% respectively for those aged 95 99 and for the centenarians. A fourth of the patients in the younger group died from cancer but only 9.5\% of the people between 95 and 98 years and 7.1\% of the centenarians died from cancer. The cancer was the direct cause of death for 67\% of the younger persons and 41\% of patients belonging to the two oldest groups. The prevalence of metastases was 63\% for tumors occurring in persons aged 75 90, 32\% in persons aged 95 98, and 29\% in the centenarians. Cancer had been accurately diagnosed prior to death in 67.4\% of persons aged 75 90, in 38.5\% of those aged 95 99, and 29.4\% of the centenarian. Cancer as cause of death had been underestimated in 16\% of the cases in the younger persons and in almost 50\% of cases of the oldest old. This study suggests that the incidence of cancer and the importance of cancer as a cause of death may decline after age 95 and that the clinical diagnoses underestimate significantly both the incidence of cancer and the prevalence of cancer deaths in the oldest old.
