A new study published in Journal of the American Geriatrics Society indicates that cancer survivors, especially older ones, are more likely to experience faster functional decline as they age, compared with those without a history of cancer.
For the study, 1728 men and women (aged 22 to 100 years) were evaluated from 2006 to 2019, with 359 of these adults reporting a history of cancer. Among all participants, a history of cancer was associated with a 1.42 greater odds of weak grip strength. Those with a history of cancer and over 65 had a 1.61 greater odds of slow gait speed than those with no cancer history, and also had lower physical performance scores. Additionally, compared with those with no history of cancer, older individuals with a history of cancer experienced steeper declines in grip strength and gait speed. Reduced prefrontal cortex area is one of the factors thought to contribute to slow gait.
“Findings from our study add to the evidence that cancer and its treatment may have adverse effects on aging-related processes, putting cancer survivors at risk for accelerated functional decline,” said senior author Lisa Gallicchio, PhD, of the National Cancer Institute. “Understanding which cancer survivors are at highest risk, and when the accelerated decline in physical functioning is most likely to begin, is important in developing interventions to prevent, mitigate, or reverse the adverse aging-related effects of cancer and its treatment.”
