Descriptive Information
Brief Title  ICMJE Diet, Exercise and Vitamin D in Breast Cancer Recurrence
Official Title  ICMJE The Effect of the Combination of Low Glycemic Index Diet, Exercise and Vitamin D on Breast Cancer Recurrence: DEDiCa Study
Brief Summary The purpose of this study is to reduce breast cancer recurrence and hence increase disease-free survival through a lifestyle program that includes a low glycemic diet, physical activity and vitamin D supplementation in women with breast cancer living in a Mediterranean country.
Detailed Description The aim of this study is to reduce breast cancer recurrence and hence increase disease-free survival through either a high intensity or a lower intensity lifestyle program that includes low glycemic index diet, physical activity and supplementation with vitamin D, for 33 months, in women living in Italy who have been surgically treated for breast cancer (either late stage or early stage but highly proliferative) within the previous 12 months. The objectives of the study are: to determine if the high intensity program is more efficacious than the lower intensity program in: 1) reducing breast cancer recurrence and 2) improving glycemic, hormonal, cardiovascular and cancer-related epigenetic markers.

Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Breast Cancer
Intervention  ICMJE
  • Other: low Glycemic Index Mediterranean diet
    All carbohydrate foods will be low GI choices (GI<70 on bread scale, e.g. legumes, pasta al dente, barley, oat, apples, oranges, berries, nuts) within a healthy Mediterranean diet (≥5 servings veg/fruit per day, ≤1 serving red meat+cold cuts/week, <7% SFA).
  • Other: Mediterranean diet
    General recommendations for a healthy Mediterranean diet (≥5 servings veg/fruit per day, ≤1 serving red meat+cold cuts/week, <7% SFA).
  • Behavioral: Moderate physical activity
    Brisk walk of at least 30min per day (or approximately 5000 steps) more than the habitual physical activity.
  • Behavioral: Basic physical activity
    General recommendations for physical activity
  • Drug: high level Vitamin D
    Vitamin D supplement (cholecalciferol) up to 4000 IU/day to reach normal blood levels of 60-80 ng/ml of 25(OH)D.
  • Drug: normal level Vitamin D
    Vitamin D (cholecalciferol) will be given only if vitamin D insufficiency is detected to bring blood levels up to normal ranges of 30ng/mL.
Study Arms  ICMJE
  • Experimental: Group A (high intensity program):

    Diet: low glycemic index (GI) Mediterranean diet. All carbohydrate foods will be low GI choices (GI<70 on bread scale, e.g. legumes, pasta al dente, barley, oat, apples, oranges, berries, nuts) within a healthy Mediterranean diet (≥5 servings veg/fruit per day, ≤1 serving red meat+cold cuts/week, <7% SFA).

    Moderate physical activity: brisk walk of at least 30min per day (or approximately 5000 steps) more than the habitual physical activity.

    Vitamin D supplement (cholecalciferol) up to 4000 IU/day to reach blood levels of 60-80 ng/ml of 25(OH)D.

    Interventions:
    • Other: low Glycemic Index Mediterranean diet
    • Behavioral: Moderate physical activity
    • Drug: high level Vitamin D
  • Active Comparator: Group B (lower intensity program)

    Diet: general recommendations for a healthy Mediterranean diet (≥5 servings veg/fruit per day, ≤1 serving red meat+cold cuts/week, <7% SFA).

    Basic physical activity: general recommendations to avoid sedentary behaviour. Vitamin D supplement (cholecalciferol) will be given only if vitamin D insufficiency is detected to reach blood levels of 30 ng/ml of 25(OH)D.

    Interventions:
    • Other: Mediterranean diet
    • Behavioral: Basic physical activity
    • Drug: normal level Vitamin D
