Postoperative physical activity before tumor recurrence was measured. Physical activity energy expenditure was quantified via metabolic equivalent task hours per week (MET\u2010h\/week). The primary end point was overall survival after tumor recurrence.

The overall survival rate at 3 years after tumor recurrence was 61.3% (95% CI, 51.8%\u201369.2%) with &lt;3.0 MET\u2010h\/week of physical activity and 72.2% (95% CI, 63.1%\u201379.6%) with \u226518 MET\u2010h\/week of physical activity (risk difference, 10.9 percentage points; 95% CI, 1.2\u201320.8 percentage points).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Higher postoperative physical activity is associated with improved overall survival after tumor recurrence in patients initially diagnosed with stage III colon cancer.
