Summary

Despite multi-modal prehabilitation (nutrition, exercise, and psychosocial interventions), 60% of older elective colorectal cancer surgery patients with poor physical function were unable to reach a minimum preoperative 400m six-minute walking distance (6MWD), a prognostic cut-point. Compared to the patients that attained \>400m 6MWD preoperatively, twice as many of \<400m patients were malnourished. Malnutrition has long been associated with worse functioning (e.g., physical, immune). The investigators hypothesize that for nutritionally deficient patients, the etiology for their poor physical function is malnutrition. Correction of malnutrition alone might thus be sufficient to achieve a 400m 6MWD before surgery and improve patient outcomes.

Detailed description

The investigators propose a randomized controlled trial of nutrition prehabilitation alone vs nutrition prehabilitation with supportive exercise in patients with malnutrition and 6MWD \<400m before elective colorectal surgery. The primary objective, and therapeutic target, will be achievement of minimal clinical important difference for the 6MWD (14m for within group comparisons and 19m between groups). Ability to adhere to the interventions will be monitored. The findings of this study will guide optimal treatment for this vulnerable population by exploring the role of nutrition alone vs. nutrition with exercise to optimize surgical outcomes.

• Malnutrition
• Physical Functional Performance

Interventions

Type	Name	Description
BEHAVIORAL	Nutrition	The nutrition intervention will be based on needs assessed by indirect calorimetry, patient-generated subjective global assessment, and 24hr recall conducted at baseline, enabling individualized caloric and protein targets. Deficits in nutrient intake will be addressed with one-on-one dietary counselling and supplementation at baseline in a quantity that matches the estimated deficit in intake. Adherence will be monitored using 24-hr recalls and weight status by the dietitian weekly.
BEHAVIORAL	Exercise	The exercise intervention will include both a resistance and an aerobic component to be performed a total of 5 times a day, 5 times per week, 5 minutes each session, totaling 125 minutes per week. The ability to perform exercises as prescribed will be monitored with a weekly in-person or virtual supervised session.
