Structured exercise prescribed like a drug in all curative-intent cancer care

The CHALLENGE trial showed a supervised exercise programme improves survival in colon cancer. Extend it to breast, prostate, and lung cancer with the same rigour.

Level-1 evidence now exists for exercise improving DFS and OS. Implementation is the barrier: reimbursement, workforce, and adherence.

Confidence
50%75%likelyOnCo editors (initial estimate), 2026-09-07 · CHALLENGE gives level-1 evidence in colon cancer; replication in other cancers is likely but slow.
Hypothesis
A 3-year structured exercise programme after curative treatment improves iDFS in TNBC (and other cancers) with effect sizes comparable to some adjuvant drugs.
Rationale
Mechanisms include insulin/IGF reduction, inflammation, and immune surveillance; effect size in CHALLENGE (DFS HR 0.72) rivals drugs.
What would test it
Run CHALLENGE-design trials in TNBC and prostate cancer with health-economic analysis and digital delivery arms.
Maturity
being tested at scale
