Abstract
[PURPOSE] The aim of this study is to evaluate the effectiveness of a culturally adapted lifestyle intervention that combines diet and physical activity (PA) in improving survival outcomes and quality of life among colorectal cancer (CRC) survivors in North Africa.
[METHODS] A multicenter, randomized, controlled phase II trial with a 2 × 2 factorial design enrolled 300 nonmetastatic CRC survivors in remission across three oncology centers. Participants were randomly assigned into four groups: combined diet + PA, diet-only, PA-only, or usual care. Interventions were delivered for 12 months, with outcomes assessed at 24 months. Primary end points were changes in dietary behaviors and PA levels; secondary end points included disease-free survival (DFS), overall survival (OS), and quality of life (FACT-G).
[RESULTS] The primary end points were achieved, with significant improvements in moderate-to-vigorous PA and dietary behaviors at 12 and 24 months across all intervention groups compared with usual care ( < .001), with the greatest and most sustained effects observed in the combined diet and PA arm. At 24 months, the combined intervention group demonstrated a 75% reduction in recurrence risk (hazard ratio [HR], 0.25 [95% CI, 0.08 to 0.78]; = .01) and an 82% reduction in mortality (HR, 0.18 [95% CI, 0.04 to 0.78]; = .01) compared with usual care. Diet-only and PA-only arms showed favorable but nonsignificant trends. Quality-of-life scores (FACT-G) improved across all intervention groups, with the greatest gains in the combined intervention arm. Subgroup analyses revealed consistent effects across age, sex, comorbidity status, tumor site, and cancer stage.
[CONCLUSION] Structured, culturally adapted lifestyle interventions integrating diet and PA significantly enhance survival and quality of life in CRC survivors, with the greatest benefits observed in the combined intervention group.
