Study Contradicts Belief that Cancer Protects against Alzheimer’s

The research, led by investigators at Huntsman Cancer Institute at the University of Utah, was published in The Journals of Gerontology: Series B.

“Diagnosis of age-related diseases, such as Alzheimer’s disease, depends on someone surviving to an age when disease onset can occur,” explains lead author Heidi Hanson, Ph.D., M.S., a Huntsman Cancer Institute research associate and research assistant professor of family and preventive medicine at the University of Utah School of Medicine.

Illustrating the concept, Hanson and her colleagues examined data from pancreatic cancer patients, whose average age of death is 73, the same age at which Alzheimer’s is typically diagnosed. While the rate of Alzheimer’s diagnoses tripled as the cancer-free population aged from 75 to 89 years old (increasing from 25 to 75 per 1,000), it remained constant in patients with pancreatic cancer (20 per 1,000).

Concluding that pancreatic cancer protects against Alzheimer’s disease is similar to saying that gunshots prevent Alzheimer’s, says senior author and Huntsman Cancer Institute investigator Ken Smith, Ph.D., distinguished professor of family and consumer studies and population science. “People who are shot rarely get Alzheimer’s because most of them die before they have the chance to. But no one would say that gunshot wounds protect against the disease.”

He adds that analyses need to consider that as people age, they are more likely to be affected by any of a number of conditions. Those dying of lethal diseases simply lack the time to develop another illness.
