Structured exercise programmes after curative treatment
A supervised, coached exercise programme for three years after bowel cancer treatment cut recurrence and death in a large randomised trial. It is the first lifestyle intervention proven to work like an adjuvant drug.
The CHALLENGE trial (CCTG CO.21, NEJM 2025) randomised 889 patients with resected stage III or high-risk stage II colon cancer after adjuvant chemotherapy to a three-year structured exercise programme with behavioural support, or health-education materials. Disease-free survival improved (5-year 80.3% vs 73.9%, HR 0.72) and so did overall survival (8-year 90.3% vs 83.2%, HR 0.63). The target was an increase of about 10 MET-hours per week, roughly 45 minutes of brisk walking most days. This is level-1 evidence in one disease; whether it generalises to breast, prostate and lung cancer is being tested, and the delivery model (physical activity consultants, supervised sessions tapering over years) is the implementation problem.
How it works
Regular aerobic activity lowers circulating insulin, IGF-1 and inflammatory cytokines, improves body composition and immune surveillance, and may reduce the fitness of dormant disseminated tumour cells. Behavioural coaching sustains adherence long enough for these to matter.
- Randomised evidence of a survival benefit with an effect size comparable to adjuvant drugs
- Cheap, safe, and improves fatigue, fitness and quality of life whatever the cancer effect
- Cardiac rehabilitation shows the delivery model can be funded at scale
- Proven so far in one cancer and one trial; replication is needed
- Adherence falls over years without coaching
- Almost no health system reimburses a supervised programme
