Background and study aims
Being overweight or obese puts you at a higher risk for health problems such as heart disease, stroke, high blood pressure and diabetes, and is also associated with an increased risk of developing many forms of cancer, including breast cancer. There is also evidence that being overweight increases the risk of recurrence and death in patients diagnosed with breast cancer. We think that diet and/or exercise counseling could help overweight or obese breast cancer patients to lose weight, which could in turn improve their quality of life and general health status, and in the long term reduce the risk of breast cancer recurrence. We aim to find out about the effects of 6 months of counseling focused on weight loss in a group of overweight or obese women previously treated for early breast cancer. The counseling is designed to promote a healthy diet or/and to increase exercise and decrease sedentary (sitting) time.
Who can participate?
Breast cancer patients aged 18 or older who are overweight or obese.
What does the study involve?
Participant are randomly allocated to one of four groups: diet counseling, exercise counseling, both diet and exercise counseling, or minimal counseling. Women allocated to the diet and/or exercise counseling groups are offered individual counseling consisting of face-to face contact, group meetings, motivational phone calls and information pamphlets. Participants are given a pedometer device (wrist band) in order to monitor their physical activity and sedentary time. Diet, quality of life, health status and participants' anxiety are assessed with questionnaires. Blood samples are collected at the start of the study and follow-up visits.
What are the possible benefits and risks of participating?
The expected result is weight loss in any of the diet or physical activity groups. Other expected long-term results include long-term weight control, increased physical fitness, increased physical activity, reduced sedentary time, healthier diet, improved health status and quality of life. We do not foresee any serious side effects. However, if participants will experience side effects, this will be reported immediately to the attention of the clinical staff. All participants will be monitored to prevent any possible deficiency or inadequate nutrient and/or calorie intake by evaluating their dietary intake. Participants will also be monitored for injuries or problems associated with the increased physical activity.

| Scientific title | Promoting weight loss through diet and exercise in overweight women with breast cancer: a four-arm randomized trial - InForma study |
| Study acronym | InForma |
| Study objectives | We hypothesized that individual dietary and/or exercise counseling could help overweight or obese breast cancer patients to lose weight, which could in turn improve their hormonal status, quality of life and general health status, and at long term limit their risk of developing breast cancer recurrence. |
| Ethics approval(s) | Ethical Committee of the European Institute of Oncology, 01/04/2015 , ref: n. R233/15 –IEO 244 |
| Health condition(s) or problem(s) studied | Overweight or obese breast cancer patients |
| Intervention | We will randomize overweight or obese patients into four intervention arms: 1. Dietary Intervention (DI) 2. Physical Activity Intervention (PAI) 3. Physical Activity And Dietary Intervention (PADI) 4. Less Intensive Intervention (LII) Women allocated to the dietary intervention and/or physical activity intervention arms will be offered an individualized dietary and/or physical activity counseling consisting of face-to face contacts, group meetings, motivational phone calls and information pamphlets. All participants will be given a pedometer device (wrist band) in order to monitor (in the two physical activity arms) participants’ physical activity and sedentary time. Dietary intake for all participants will be repeatedly assessed with validated food frequency questionnaires. Quality of life, health status and participants' anxiety will be assessed with self-administered questionnaires including FACT-B and the State-Trait Anxiety Inventory (STAI) questionnaires. Blood samples will be collected at baseline and follow-up visit to assess glucose, insulin, lipid and hormone profile. Women allocated to the less intensive intervention (or minimal counseling) arm will be considered as control group. Participants will be followed up for a further 18 months and outcome assessments will be made at 12 and 24 months. |
| Intervention type | Behavioural |
| Primary outcome measure | Change in body weight (weight loss ≥5% of the baseline body weight) at the end of the 6-month intervention |
| Secondary outcome measures | The secondary outcome measures will be assessed along intervention including: 1. Maintain long-term weight control, measured at baseline, 6 months, 12 months and 24 months 2. Increase physical activity levels and reduce physical inactivity from baseline, measured at baseline, 6 months, 12 months and 24 months 3. Change in dietary intake (increase adherence to healthy diet from baseline), measured at baseline, 6 months and 24 months 4. Evaluate the effect of intervention on long-term breast cancer recurrence 5. Change in health status and quality of life, measured at baseline, 6 months, 12 months and 24 months 6. Evaluate the effect of intervention on blood lipid profile (total cholesterol, LDL and HDL cholesterol, triglycerides), measured at baseline, 6 months and 24 months 7. Evaluate the effect of intervention on biomarkers (estradiol, C-reactive protein (CRP), insulin, glucose), measured at baseline, 6 months and 24 months |
