Breast and Ovarian Cancer Syndrome (HBOC) is characterized by mutations in tumor suppressor genes such as BRCA1 and BRCA2, which increase the carrier's risk of developing breast and ovarian cancer, especially before 40. In this pathology the DNA damage is increased because there is a state of chronic inflammation, plus the antineoplastic treatments and changes in body composition result in oxidative stress. The inductions of epigenetic changes by a nutritional intervention with an specific distribution of macronutrients, micronutrients and polyphenols, not only ensures an optimal nutritional status, but also shows a decrease in oxidative stress, and therefore in DNA damage. The aim of this study is to assess if the DNA damage in patients with HBOC decreases after the nutritional intervention.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | DNA damage change | A blood sample will be taken to assess DNA damage (ELISA) by 8-hydroxy-2-deoxyguanosine (8-OHdG), a modified nitrogen base indicating oxidative damage to DNA, before and after nutritional intervention. | 12 weeks | |
Secondary | Body composition change | A bioelectrical impedance analysis will be used to assess the body composition through the reactance and resistance values (both measured in Ohm), before and after nutritional intervention. | 12 weeks | |
Secondary | Muscular strength change | A hand grip dynamometer will be used to assess the muscular strength in kg, both before and after the nutritional intervention. | 12 weeks | |
Secondary | Dietary change: Energy | A 24-hour recalls will be performed to evaluate amount of energy (measured in kilocalories), before and after the nutritional intervention. | 12 weeks | |
Secondary | Dietary change: Macronutrients | A 24-hour recalls will be performed to evaluate amount of carbohydrate, protein and fat (all measured in percentage and grams), before and after the nutritional intervention. | 12 weeks | |
Secondary | Dietary change: Micronutrients | A 24-hour recalls will be performed to evaluate amount of vitamin E, calcium, zinc and magnesium (all measured in milligrams), before and after the nutritional intervention.
A 24-hour recalls will be performed to evaluate amount of folate, vitamin A and D, selenium, lycopene, and flavones (all measured in micrograms), before and after the nutritional intervention. |
