Circuit-based prehabilitation exercise intervention

The exercise intervention will consist of light-to-moderate intensity aerobic, resistance, and mobility exercises. These exercises will be performed in a circuit type manner. Participants will perform similar exercises that are modified to meet their individual abilities. Exercise intensity, modifications and substitutions will be determined for each participant based on their medical history, 6 minute walk test results, and baseline frailty scores. Exercise sessions will be performed 3x/wk beginning at 30 min and progressing to 60-min as tolerated for a minimum of four weeks but will continue up until the time of the participants surgery. A hybrid approach will be used for the exercise sessions whereby the participant must attend the first exercise session in person and subsequent sessions will be delivered virtually. Sessions will be overseen by the study Clinical Exercise Physiologist.

Prehabilitation Exercise Intervention

Individuals with ovarian cancer have very poor survival rates. This is because the cancer is not usually detected until it has reached advanced stages. How long an individual survives also is determined by the cancer treatment they receive. Although there are best treatment practices to improve survival, some women have other conditions that limit treatment options. One such condition seen in as many as 50% of women with advanced ovarian cancer is frailty (an age-related decline in function and health). This is a major concern as doctors will often have to change how the cancer is treated based on the patient being frail. For example, patients living with frailty are less likely to have their full tumor removed during surgery. They are also more likely to have complications with surgery, stay in the hospital longer, and recover less well from surgery overall. Patients living with frailty also are more likely to experience delays in their chemotherapy starting, receive lower doses of chemotherapy and/or receive fewer cycles of chemotherapy. These changes in treatment may decrease how long a patient survives after diagnosis. Thus, research is needed to explore strategies to decrease frailty in patients who require treatment for advanced ovarian cancer. An option gaining more attention is physical exercise (e.g. walking, repeatedly rising from a chair). Exercise performed before surgery, which is called prehabilitation, can improve how well a patient recovers after surgery and increase how long they survive. Research has shown that prehabilitation is very beneficial for patients undergoing surgery for heart disease. However, it is not clear whether prehabilitation works for those with advanced ovarian cancer that are going to have surgery. Therefore, the investigators want to explore how a 4+ week exercise program performed while waiting for surgery for advanced ovarian cancer changes frailty and how a patient recovers after surgery. The investigators will specifically look whether the exercise program: 1) reduces how frail a patient is before surgery; 2) improves how well the patient recovers after surgery; and 3) affects the patient's chemotherapy treatment plan. This study will provide important information about the ability of prehabilitation exercise to improve surgical and treatment outcomes in women with advanced ovarian cancer. Overall, it is believed that exercise has the potential to improve the survival of advanced ovarian cancer patients.

Prehabilitation for Ovarian Cancer Patients

The Impact of Prehabilitation Exercise on Frailty and Treatment Outcomes in Ovarian Cancer Patients

Participant accrual calculated as % of patients referred divided by number of patients consented to participation

Participant attrition calculated as % of consented patients who complete a minimum of 4 weeks of pre-surgical exercise divided by number who withdraw

Participant program adherence calculated as % of minimum number of exercise sessions completed (e.g., 3 sessions/week for a minimum of 4 weeks for a total of 12 sessions) divided by total number of available exercise sessions over 12-week intervention

All exercise-related adverse and serious adverse will be recorded

Frailty will be assessed using the Clinical Frailty Scale (CFS). The CFS is a The CFS is a 9-point scale (1 - very fit, through very severely frail to 9 - terminally ill) developed for healthcare professionals to summarize the overall level of fitness/frailty of an individual. The CFS covers domains of mobility, energy, physical activity, and function. The higher the score on the CFS the more frail/less fit an individual is.

Surgical complexity will be assessed based on Enhanced Recovery After Surgery (ERAS) guidelines. Complexity scores will be interpreted as "low" (3 or fewer points), "intermediate" (4-7 points), and "high" (8 or more points).

Post-surgical outcomes will be assessed based on Enhanced Recovery After Surgery (ERAS) guidelines. Specific outcomes will include post-op glucose control, analgesia usage, pain, daily weight, early mobilization, and post-operative complications.

Surgical complications will be assessed based on Enhanced Recovery After Surgery (ERAS) guidelines. Specific outcomes will include length of hospital stay and number of readmissions.

Chemotherapy completion rates will be examined through documentation of total drug dose received, changes in dose, cycle delays, and/or discontinuation of treatment

Weight (kg) and height (m) will be used to calculate BMI

The six-minute walk will be used to calculate aerobic fitness

Muscular fitness will be assessed using the Canadian Society of Exercise Physiology's Physical Activity Training Protocol (CSEP-PATH) and will include the timed sit-to-stand and grip strength.

Health-related quality of life will be assess using the EuroQoL five dimensional questionnaire (EQ-5D-5L). The EQ-5D-DL measures mobility, self-care, usual activities, pain/discomfort, and anxiety/depression; higher scores indicate higher problems

The Functional Assessment of Cancer Therapy for Ovarian Cancer (FACT-O) will be used to measure cancer-specific quality of life; 27-item questionnaire with higher scores indicating higher overall quality of life.
