Improving health before colorectal cancer surgery for older patients with malnutrition

Is Correction of Malnutrition Sufficient to Improve Low Physical Function Before Elective Colorectal Cancer Surgery? A Randomized Controlled Trial of Nutrition vs Nutrition and Exercise Prehabilitation

Not applicable Interventional McGill University · NCT05999370

This study is testing whether older patients with colorectal cancer who are malnourished can do better before surgery by focusing on nutrition alone or nutrition plus exercise.

What this trial studies

This clinical trial investigates the effectiveness of nutrition prehabilitation alone versus nutrition combined with supportive exercise for older colorectal cancer patients who are malnourished and have low physical function. The study focuses on patients aged 65 and older who are scheduled for primary colorectal surgery and have a six-minute walking distance (6MWD) of less than 400 meters. By addressing malnutrition, the researchers aim to improve patients' physical performance before surgery, potentially enhancing surgical outcomes. The trial will measure adherence to interventions and the impact on achieving a clinically significant improvement in walking distance.

Who should consider this trial

Good fit: Ideal candidates are patients aged 65 and older with colorectal cancer scheduled for surgery, who have a 6MWD of less than 400 meters and a malnutrition assessment score of 9 or higher.

Not a fit: Patients with metastatic cancer or those with conditions that contraindicate exercise, such as dementia or Parkinson's disease, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve preoperative physical function and overall outcomes for malnourished colorectal cancer patients.

How similar studies have performed: While the approach of combining nutrition and exercise is established, this specific focus on malnourished older patients with colorectal cancer is relatively novel and has not been extensively tested.
