Long-term effects of low-dose aspirin on cancer, heart disease, bleeding, and dementia over 15 years

Aspirins legacy on cancer and overall benefit: risk balance over a 15-year horizon

What this research studies

If you are an older adult, researchers will follow people from the ASPREE-XT extension who did or did not take low-dose aspirin and track cancer, cardiovascular events, gastrointestinal bleeding, and dementia outcomes over many years. You would contribute by attending follow-up visits and allowing access to medical records and screening results so researchers can count long-term outcomes. The team will update risk models to better predict who is likely to benefit or be harmed, with special attention to the oldest-old. The goal is to help personalize aspirin decisions based on an individual's long-term risks and benefits.

Who could benefit from this research

Good fit: Ideal candidates are community-dwelling older adults without prior cardiovascular disease who either participated in ASPREE or are similar primary prevention patients, especially those aged 70 and older including the oldest-old.

Not a fit: People with active bleeding disorders, those already needing aspirin for established cardiovascular disease, or those with very limited life expectancy are unlikely to gain benefit from this prevention-focused work.

Why it matters

Potential benefit: If successful, this work could help older adults and their clinicians decide when a short course of low-dose aspirin is likely to reduce long-term cancer or cardiovascular deaths without unacceptable bleeding or dementia risk.

How similar studies have performed: Prior ASPREE trial results were mixed—aspirin raised bleeding risk and did not improve short-term disability-free survival, though later follow-up hinted at reduced cancer mortality, so long-term effects remain uncertain.
