Major surgery is a stressful procedure; good recovery after surgery is important to patients and their doctors. Studies done at the McGill University Health Centre (MUHC) with cancer patients awaiting surgery have shown that exercise combined with simple diet recommendations (which may include a supplement) and relaxation techniques before surgery helped speed up the ability to resume walking after surgery.
These results have made the investigators aware that exercise and good nutrition are as important before surgery as they are after surgery; while it is common practice to start strengthening the body after surgery (rehabilitation), there may be some advantage to begin this process before surgery (prehabilitation).
The purpose of this study is to see if the following program, either before or after surgery, can help patients recover from liver, pancreas or bile duct surgery:
The investigators will see if following this program will have an effect on participants' ability to walk before and after surgery.

| Change in functional walking capacity as measured by the six-minute walk test (6MWT) | The 6MWT evaluates the ability of an individual to maintain a moderate level of physical activity over a time period reflective of the activities of daily living. Subjects are instructed to walk back and forth, in a 20 meter stretch of hallway, for six minutes, at a pace that would make them tired by the end of the walk; encouragement and feedback are given according to published guidelines. They are allowed to rest during the test if needed, but this time is included in the 6 minutes. Reference equations are available for calculating percent of age- and gender-specific norm. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Measure | Description | Time Frame |
|---|---|---|
| Timed up and go test | Investigators will measure the time required for a participant to stand up from being seated, walk a distance of 3 metres, turn around and walk back to the chair, and sit down. This measure will be administered based on Canadian Society for Exercise Physiology standards. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Measure | Description | Time Frame |
|---|---|---|
| Lower extremity strength - assessment of change over time | Optional measure: assessed using the Biodex System 3 (Biodex Medical Systems, Shirley, NY). | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |

| Nutrition | Other | Patients will be asked to fill in a 3-day food diary. A registered dietitian (RD) will review this diary, provide a full nutritional assessment, and ensure patients are following a high-protein diet (1.5 g of protein/kg/day). A whey-protein supplement may be provided to patients, should they require it. The RD will also ensure adequate calorie consumption for weight maintenance and will provided advice to help ease any GI issues the patients may be experiencing. |
|
| Relaxation techniques | Behavioral | Patients will see a psychologist who will provide relaxation techniques (eg. imagery, visualization, deep breathing exercises) to help patients manage anxiety prior to surgery. |
|
| 30-second sit to stand test | Investigators will measure the number of times participants can stand from a seated position in 30-seconds. This measure will be administered based on Canadian Society for Exercise Physiology standards. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| 30-second arm curl test | Investigators will measure the number of times participants can perform a full arm curl in 30-seconds. Both arms will be assessed, one at a time. This measure will be administered based on Canadian Society for Exercise Physiology standards. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Change in handgrip strength | To be measured using the Jamar hydraulic hand dynamometer. Two measures from each hand will be taken, with patient seated and arm bent at a 90-degree angle. The average of the two measures for each hand will be recorded and compared to normative data. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Change in body composition | Body composition will be measured via dual-energy X-ray absorptiometry (DXA; Lunar Prodigy Advance, General Electric Healthcare, Madison, WI). Studies from the McGill Nutrition and Performance Laboratory group have validated the use of DXA in advanced cancer patients. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Assessment of food intake and change over study period | Participants will be asked to bring a 3-day food diary to their baseline visit to obtain detailed information about the quantity and type of food and beverages consumed during a non-consecutive 3-day period. Overall energy intake, as well as macronutrient distribution (e.g., amount of carbohydrates, fats, proteins, and fibre at each meal) will be calculated using the Food Processor SQL Nutrition Analysis software. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Perioperative data | This data will include operative characteristics, transfusion rates, length of surgery, intraoperative complications and length of stay. | 7 days post-operatively |
| Postoperative complications | Including surgical site infection, other infectious complications (such as pneumonia, urinary tract infection, line sepsis), bile leak, hemorrhage, deep vein thrombosis, etc., will be recorded and scored using the Clavien Classification. | 4 weeks post-operatively |
| Health-related quality of life (HRQL) - assessment of change over time | As measured by the acute (1 week recall period) Functional Assessment of Cancer Therapy (FACT) survey. This questionnaire also has versions that identify symptoms more specific to hepatobiliary and colorectal cancer patients; this is of relevance to this study given liver metastasis occurs in these patients. The questionnaire is separated into five subscales: 1) physical well-being, 2) social/family well-being, 3) emotional well-being, 4) functional well-being, 5) additional concerns (specific to cancer type). Each question is scored 0-4 on a likert scale, with 0 indicating, "not at all," and 4 indicating, "very much." These scores are then reversed where applicable and added. A higher score indicates better QoL. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| The Edmonton Symptom Assessment System (ESAS) - assessment of change over time | Currently used at the MUHC Cedars Cancer Centre to assist in the assessment of pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, well-being, and shortness of breath. Each symptom is rated from 0 to 10 on a numerical scale based on severity, with 0 indicating that the symptom is absent and 10 that it is the worst possible severity. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Physical activity level - assessment of change over time | Will be measured through the Community Health Activities Model Program for Seniors (CHAMPS) questionnaire. The CHAMPS is a self-reported measure of physical activity, comprising 41 activities evaluated according to the total number of hours done during an average week. Each physical activity is assigned a metabolic equivalent (MET) value yielding average weekly caloric expenditure for the listed physical activities. There is evidence for the validity of CHAMPS as a measure of postoperative recovery. Data will be categorized as either mild, moderate or intense activity and changes in the number of hours spent performing activities within each category will be assessed. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Nutritional status - assessment of change over time | To be assessed using the Abridged Patient-Generated Subjective Global Assessment (aPG-SGA); a validated questionnaire used to assess the nutritional and functional status of cancer patients. The scoring system allows patients at risk for malnutrition to be identified and triaged for nutritional intervention. The aPG-SGA may also be useful in monitoring short-term changes in nutritional status. A score ≥9 indicates a critical need for nutritional intervention. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Fatigue - assessment of change over time | To be assessed using a visual analog scale (1-10) and the Brief Fatigue Inventory (BFI). The BFI assesses the level of fatigue and its impact on activities of daily living. The test has 9 questions: three questions are designed to assess the patient's fatigue during the immediate waking hours and 6 questions address how fatigue has interfered in the patient's life over the previous 24 hours. Each question uses a scale rating from "0" (no fatigue) to "10" (unimaginable fatigue) for a total of 90 points. | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Weight - assessment of change over time | Body weight will be measured (Kg) | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Height | Height will be measured with a stadiometer (m) | Baseline |
| Body mass index - assessment of change over time | Calculated wt (kg)/ht^2 (m) | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Blood pressure - assessment of change over time | Systolic and diastolic at rest (mmHg) | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
| Heart rate - assessment of change over time | Beats per minute measured using a pulse oximeter | Baseline, pre-operative assessment, 4 weeks post-operative, 8 weeks post-operative |
