|Breast Cancer||Dietary Supplement: Polyphenol||Not Applicable|
The objective of this exploratory trial is to determine the disposition and characterise the metabolic profiling of dietary polyphenols in normal and malignant glandular breast tissues from newly diagnosed breast cancer patients.
The patients consumed a polyphenol-rich dietary supplement containing 37 different phenolics and 2 methylxanthines (theobromine and caffeine) from the diagnosis to the surgery. The metabolic profiling was characterized in normal and malignant breast tissues as well as plasma and urine using UPLC-ESI-QTOF-MS/MS.

Experimental: Polyphenol group
Patients consumed a polyphenol-rich dietary supplement (commercial lemon, orange, pomegranate, olive, grape, cocoa, curcuma and broccoli extracts), mainly rich in simple phenolics such as hydroxytyrosol and the polyphenols procyanidins, hesperidin, eriocitrin, curcumin, resveratrol, punicalagin and ellagic acid. Cocoa extract also contains the methylxanthines theobromine and caffeine.
Dietary Supplement: Polyphenol
Patients consume 3 capsules/day (474 mg phenolics/day) from the biopsy-confirmed breast cancer diagnosis to the surgery
No Intervention: Control group
Participating patients did not consume the supplement but provided biological samples to the trial
- Quantification of dietary polyphenols and methylxanthines in breast tissues [ Time Frame: 1-24 months ]
Quantification of dietary polyphenols and methylxanthines in normal and malignant mammary tissues from breast cancer patients using ultra-high resolution liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS/MS).
- Quantification (pmol/g) of each phenolic-derived metabolite in breast tissues.
- Quantification (pmol/g) of each methylxanthine-derived metabolite in breast tissues.
- Quantification of dietary polyphenols and methylxanthines in plasma and urine [ Time Frame: 8-24 months ]
Quantification of dietary polyphenols and methylxanthines in urine and plasma from breast cancer patients using ultra-high resolution liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS/MS).
- Quantification of each phenolic-derived metabolite in urine and plasma (nmol/L).
- Quantification of each methylxanthine-derived metabolite in urine and plasma (nmol/L).
