DEMETRA: Dietary Habits, Nutritional Knowledge and Physical Activity Assessment in Early Stage Breast Cancer Patients
Study Details
Study Description
Brief Summary
The advances in early detection coupled with improvements in treatments have led to an ever increasing number of breast cancer survivors. New methods to improve outcomes, including strategies aimed at improving the quality of life and reducing the risk of other diseases, may complement the currently available treatment options. In particular, interventions targeting diet, weight and physical activity can reduce the risk of cancer occurrence, prevent cancer recurrence, and improve survival and the quality of life.This cross-sectional, prospective, observational study aims at evaluating dietary habits and nutritional knowledge in patients with early hormone receptor positive and hormone receptor negative breast cancer.

Detailed Description
The advances in early detection coupled with improvements in treatments have led to an ever increasing number of breast cancer survivors. New methods to improve outcomes, including strategies aimed at improving the quality of life and reducing the risk of other diseases, may complement the currently available treatment options. In particular, interventions targeting diet, weight and physical activity can reduce the risk of cancer occurrence, prevent cancer recurrence, and improve survival and the quality of life.
The Women's Intervention Nutrition Study (WINS) and the Women's Healthy Eating and Living (WHEL) Randomized Trial examined the impact of dietary intervention on disease outcome in patients with early stage breast cancer, but with different results.
The Women's Intervention Nutrition Study randomized 2437 women with early stage breast cancer to receive a low-fat dietary intervention or usual care control and it demonstrated that dietary intervention improves disease free-survival of breast cancer patients receiving conventional cancer management. Although these benefit was no longer statistically significant at a longer follow-up, an exploratory subgroup analysis revealed that patients with hormone receptor-negative breast cancer continued to experience benefits from the intervention.
The Women's Healthy Eating and Living (WHEL) Randomized Trial, randomized 3088 women previously treated for early breast cancer, to receive low-fat, high-fruit, vegetable and fiber diet or to the control group. This trial failed to demonstrate a benefit in terms of recurrence rates within the experimental group.
Given the discrepancies among the findings of these two large trials, dietary changes are not routinely suggested as part of adjuvant therapies for breast cancer survivors and further research is needed to expand knowledge in this area. This study aims at evaluating dietary habits and nutritional knowledge in patients with early hormone receptor positive and hormone receptor negative breast cancer.
Study Design
Outcome Measures
Primary Outcome Measures
- Evaluation of nutritional knowledge in patients with surgically removed early breast cancer [At baseline and at 3-5 years of follow up]
Median and interquartile range of items of nutritional knowledge questionnaire in patients with surgically removed early breast cancer
- Evaluation of dietary habits in patients with surgically removed early breast cancer [At baseline and at 3-5 years of follow up]
Frequency of different answers at dietary habits questionnaire
- Evaluation of physical activity in patients with surgically removed early breast cancer [At baseline and at 3-5 years of follow up]
Frequency of different answers at activity questionnaire
Secondary Outcome Measures
- Association between nutritional knowledge and physical activity [At baseline and at 3-5 years of follow up]
difference in nutritional knowledge score between subgroups of patients with different levels of physical activity
- Association between nutritional knowledge and dietary habits [At baseline and at 3-5 years of follow up]
difference in nutritional knowledge score between subgroups of patients with different frequencies of consumption for selected foods
- Association between dietary habits and physical activity [At baseline and at 3-5 years of follow up]
association between frequencies of consumption for selected foods and levels of physical activity
- Association between dietary habits and BMI [At baseline and at 3-5 years of follow up]
Difference in frequencies of consumption for selected foods between BMI categories
- Association between dietary habits and waist to hip ratio [At baseline and at 3-5 years of follow up]
Difference in mean of waist to hip ratio between subgroups of patients with different frequencies of consumption for selected foods
- Association between dietary habits and anthropometric measure [At baseline and at 3-5 years of follow up]
Difference in mean of waist, hip, abdomen circumferences between subgroups of patients with different frequencies of consumption for selected foods
- Association between dietary habits and blood tests results [At baseline and at 3-5 years of follow up]
Differences in mean level of selected blood test (e.i glycemia, HDL, LDL) between subgroups of patients with different frequencies of consumption for selected foods
- Association between dietary habits and disease relapse [From baseline up to 5 years of follow up]
Association between answers to dietary habits questionnaire and progression free survival defined as the time from study enrolment until progression or death from any cause whichever comes first
- Association between dietary habits and overall survival [From baseline up to 5 years of follow up]
Association between answers to dietary habits questionnaire and overall survival defined as the time from study enrolment until death from any cause
