Malignant Breast Tissue Neoplasm Clinical Trial
— BEETOfficial title:
Is Dietary Nitrate Effective in Reducing Aerobic Glycolysis (AG) in Breast Cancer? - A Longitudinal Study Using Specialist Magnetic Resonance (MR) Methods
Breast cancer is the most prevalent cancer affecting women, with 1 in 8 women in the UK
developing breast cancer in their life time. Chemotherapy drugs, currently used for locally
advanced breast cancers, are associated with side effects while dietary supplements have
complex effects with a relatively small effect size.
Breast tumours have different metabolism compared to healthy tissue, including elevated
lactate production by aerobic glycolysis (AG), an underpinning feature of metabolism in
breast cancer cells. Dietary nitrate, contained in leafy green vegetables and beetroot, has
been shown to improve energy efficiency in exercising skeletal muscle, positioning itself as
a disruptor of AG.
The purpose of this study is to examine if dietary nitrate can disrupt AG and as a result to
halt or even reverse tumour progression and survival. This study will look at scans of breast
tumours using magnetic resonance imaging (MRI). Changes to tumour related biochemical
substances will be measured by advanced magnetic resonance spectroscopy and changes to tissue
structure will be measured by advanced diffusion MRI techniques.
In this study, 16 patients undergoing surgery will be recruited for two MRI scans following a
5 day intervention programme.
