Nutritional Intervention and DNA Damage of Patients With HBOC

March 4, 2024 updated by: Juan Antonio Pineda Juárez, Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado

Effects of a Nutritional Intervention in DNA Damage of Patients With Hereditary Breast and Ovarian Cancer Syndrome

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.

Detailed Description

Breast and Ovarian Cancer Syndrome (HBOC) is a genetic disease characterized by mutations in tumor suppressor genes such as BRCA1 and BRCA2, elevation of Reactive Oxygen Species (ROS), inflammation and DNA damage; all this as a result of the pathology itself. Antineoplastic treatments and changes in body composition such as malnutrition, cachexia and obesity lead to an increase of the inflammatory state. The induction of epigenetic changes by a nutritional intervention suggests that an hypo caloric diet, complex carbohydrates, polyunsaturated fatty acids, some amino acids, and some vitamins, minerals and polyphenols as well, can reduce DNA damage because of the interaction between mechanisms related with DNA stability and reparation, cellular replication, induction of apoptosis, and antioxidant systems. Previous studies report that using polyphenols supplements can reduce de DNA damage, but when the administration is only through food there's no benefit at all. So the aim of this study is to assess if the use of different micronutrients and polyphenols in conjoint can make synergism and reduce de DNA damage without the need of supplements.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
DNA damage change
Time Frame: 12 weeks
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Body composition change
Time Frame: 12 weeks
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
Muscular strength change
Time Frame: 12 weeks
A hand grip dynamometer will be used to assess the muscular strength in kg, both before and after the nutritional intervention.
12 weeks
Dietary change: Energy
Time Frame: 12 weeks
A 24-hour recalls will be performed to evaluate amount of energy (measured in kilocalories), before and after the nutritional intervention.
12 weeks
Dietary change: Macronutrients
Time Frame: 12 weeks
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
Dietary change: Micronutrients
Time Frame: 12 weeks

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.
