Feasibility of Lifestyle Intervention in BRCA1/2 Mutation Carriers (LIBRE)

This study is ongoing, but not recruiting participants.

BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian cancer during their lifetime. There is evidence from the literature that for sporadic breast cancer disease risk and the course of disease can be significantly influenced by physical activity, nutrition and weight. The hypothesis of this 3 year, prospective randomized multicenter feasibility trial is that a structured life-style intervention program with exercise training and mediterranean diet is feasible and improves the nutritional and fitness status as well as the weight, the quality of life and stress reacting capacity.

Condition Intervention
Hereditary Breast and Ovarian Cancer
Behavioral: Structured exercise training plus mediterranean diet

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Prevention
Official Title: Prospective Randomized Multicenter Trial to Assess the Feasibility of a Structured Physical Exercise Training and Mediterranean-style Diet in Women With BRCA1/2 Mutations
