- Design
- Prospective single-centre randomised clinical trial
- Population
- 40 analysed adults with head and neck cancer proposed for definitive chemoradiotherapy
- Primary outcome
- Six-minute walk distance at the end of the pre-treatment period
- Effect
- Adjusted difference 28.6 m (95% CI 4.1 to 53.1), P = 0.023
FIT4TREAT randomised adults with head and neck cancer who were scheduled for definitive chemoradiotherapy to supervised aerobic and resistance exercise three times a week or usual care, from baseline until radiotherapy began. The primary outcome was six-minute walk distance at the end of that period.
Forty-seven patients were enrolled and 40 analysed. After adjustment, exercise gave a greater walk distance (difference 28.6 m, 95% CI 4.1 to 53.1, P = 0.023). Lower-limb function was better, and quality-of-life summary, social functioning and body image were better preserved.
The trial is single-centre and small, with a modest confidence interval at the lower end, and it measured function before treatment, not outcomes of treatment itself. It supports exercise as a safe addition during the pre-treatment waiting period in patients able to take part.
- Six-minute walk distance was 28.6 m greater with exercise (95% CI 4.1 to 53.1).
- Lower-limb function and some quality-of-life scores were better.
- Only 40 patients were analysed at one centre.
- Outcomes were measured before cancer treatment began.
- Refer fit patients for supervised exercise while they wait for chemoradiotherapy.
Why it matters
The weeks before chemoradiotherapy are usually used for logistics, not conditioning.
Don't overread it
A 40-patient single-centre trial measured fitness, not tolerance of treatment, survival or toxicity.
The statistics, in plain English
A difference of 28.6 m with a lower confidence limit of 4.1 m means the true gain could be small. Quality-of-life findings were secondary outcomes with unadjusted P values, so they are weaker.
