EXercise And Colo-Rectal Cancer Trial (EXACT)

The Feasibility and Effects of a Home-based Walking and Strengthening Intervention on Physiological, Biochemical and Psychological Outcomes in Colo-rectal Cancer Survivors

The aim of this study is to assess the feasibility and effectiveness of a home-based walking and strengthening intervention on physiological, biochemical and psychological outcomes in colo-rectal cancer survivors.

The intervention consists of a 12-week home-based walking and strengthening programme for colo-rectal cancer survivors post any anti-cancer treatment. It aims to gradually increase participants physical activity levels so that they start achieving the recommended levels of at least 150 minutes moderate intensity aerobic activity per week and strengthening exercise for all major muscle groups at least twice per week.

As well as usual care, the intervention group will receive weekly telephone calls and a behaviour change interview at baseline. Participants will be recruited from the Cancer Centre at the Belfast City Hospital. Assessments will be taken at baseline (0 weeks), post intervention (12 weeks) and also at a 3-month follow-up (24 weeks). The control group will receive the same assessments at the same time-points however they will continue to receive usual care with the intervention information (including pedometer, exercise booklet, diary and behavioural change interview) being given at the 3-month follow-up appointment.

Study Overview

• Status: Unknown
• Conditions: Colo-rectal Cancer
• Intervention / Treatment: Behavioral: Exercise; Other: Control

Detailed Description

The number of people living with and beyond cancer is ever increasing and now more than ever there is a need to facilitate the appropriate rehabilitation of these patients. Exercise interventions and increased physical activity have been well documented in their ability to improve multiple aspects of health in cancer survivors; including quality of life, fatigue as well as all-cause and cancer-specific mortality. Whilst the main outcome from this study will be its feasibility, the novel aspect is the analysis of biological markers in the blood. Although there is much evidence on the benefits of exercise for colo-rectal cancer survivors, the biological mechanisms underlying its effects in this population are still elusive. Therefore this intervention was designed to investigate the feasibility and effectiveness of a home-based walking and strengthening programme on physiological, biochemical and psychological outcomes in colo-rectal cancer survivors.

Participants are first approached by their surgeon/oncologist and assessed for their eligibility. If they are deemed eligible they are then referred to the researcher in the waiting room to be given more information about the study. If interested, they receive the participant information sheet and consent forms to take home for a period of at least 24 hours, after which the researcher calls to confirm their interest. Visit 1 is then scheduled in order for the participant to sign the consent forms and receive the 'ActiGraph' accelerometer which they wear for 7 consecutive days in order to measure their baseline physical activity levels. With permission, the patients GP will be advised by letter that the patient is commencing the study.

After the seven days the participant attends the Northern Ireland Clinical Research Facility at the Belfast City Hospital for the first assessment session. The outcome measures assessed include analysis on feasibility, quality of life, fatigue, biological markers, anthropometry, strength, cardiovascular endurance and physical activity levels. The intervention group then receive the behaviour change counselling session along with the exercise booklet, diary and pedometer. Weekly phone calls are made to intervention participants for 12 weeks to monitor their progress. The control group receives usual care without weekly phone calls. On week 11 both groups are posted their accelerometer to record activity levels and then attend the City Hospital to repeat all assessments. Both groups are not contacted again until week 23 when they are posted the accelerometer for the final time and their follow-up assessments are complete. It is at this assessment session that the control group receive the behaviour change session and intervention materials.

After each assessment day, blood samples are transported via a specifically designed fridge, to the Ulster University campus to be stored at -80 degrees Celsius for future analysis. All other study information such as questionnaires and collected data are stored as per University protocol in storage containers in a designated locked room on campus.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Exercise Group; As well as usual care, this group receive a behavioural change session and intervention information regarding the exercise programme. The home-based walking and strengthening intervention is individually tailored for each participant. They receive a booklet, diary and pedometer to guide them as well as weekly phone calls for 12 weeks to monitor their progress.	Behavioral: Exercise; The exercise programme aims to gradually increase participants physical activity levels so that they start achieving the recommended levels of at least 150 minutes moderate intensity aerobic activity per week and strengthening exercise for all major muscle groups at least twice per week.
Other: Control Group; This group attends and participates in the same assessment outcomes as the intervention group and receives usual care for the duration of the study. However they are not given any exercise instructions and do not receive the intervention information until their final assessment at week 24. They are aware of their group allocation throughout the duration of the study.	Other: Control; The control group will receive usual care whilst attending for the same 4 visits as the intervention group and have the same outcome measures tested. They will however receive the intervention information on their last visit.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Feasibility	The feasibility of the trial will be characterized by recording such things as; the number of eligible patients, the follow-up rates, response rates to questionnaires and adherence/compliance rates.	24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity	The participants will wear an 'ActiGraph' accelerometer around their waist for 7 consecutive days in order to calculate their activity levels.This will be measured by analyzing the minutes spent in moderate/vigorous/sedentary behaviour.	For 7 days at three different times; baseline, week 11 and week 23.
Cardiovascular Endurance	Participants walk between two cones 30 metres apart for six minutes. The cones are in a closed off corridor in the hospital with no obstructions. This is measured in meters covered in the 6 minutes.	Week 0, 12 and 24
Lower limb strength	The 30 second sit-to-stand test requires the participants to sit down and stand up from a chair as many times as they can in 30 seconds. The outcome is the number of repetitions completed.	Week 0, 12 and 24
Quality of life	Various validated questionnaires will be given to assess quality of life and fatigue; Positive and Negative Affect Schedule (PANAS), EQ-5D-3L questionnaire, FACT-C and FACT-F.	Week 0, 12 and 24
Demographics	A specially designed demographics questionnaire to gain an insight into the participant characteristics. Outcomes measured will be; age/ethnicity/employment status/marital status.	Week 0, 12 and 24
