Home-based exercise after oral-cancer diagnosis

Evidence label: Negative primary body-composition result with activity signal · Clinical goal: limit muscle loss and fatigue and support quality of life

Evidence at a glance

Population: 119 people with oral cancer were randomized; 108 entered the analysis.
Intervention: six months of individualized, unsupervised home exercise after one face-to-face physiotherapy visit and five telephone follow-ups.
Result: activity increased, but fat-free-mass loss did not differ between groups.

What was studied

Participants were followed for one year. The prespecified primary outcomes were change in fat-free mass and fatigue at four months. Physical activity, weight, malnutrition and multiple quality-of-life domains were secondary.

What the evidence shows

The program increased self-reported physical activity at several time points, but did not reduce fat-free-mass loss relative to control. Fatigue differences were not statistically significant. Global quality-of-life differences at two and four months favored exercise but were under 10 points and were not sustained at six or 12 months.

This trial supports feasibility and behavior change more than a firm muscle-preservation claim. It did not test cancer control.

Limits and uncertainty

Eleven randomized participants withdrew or died before the first follow-up and were excluded; most had advanced disease. Exercise was unsupervised and activity was self-reported. The population was mostly performance-status 0 with early-stage oral cancer, and about 80% used protein-rich oral nutrition supplements.

Safety and practical context

Oral-cancer care can involve swallowing problems, weight loss, feeding tubes, wound recovery and radiotherapy effects. Exercise is not a substitute for nutrition assessment or swallowing rehabilitation. Rapid weight loss, dehydration, aspiration symptoms or wound problems require clinical care.

Questions for the care team

Is muscle loss, fatigue or simply maintaining activity the most important goal for me?
Do I need dietitian and swallowing support alongside exercise?
Would supervised resistance training be safer or more effective than an unsupervised home plan?
