Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Breast cancer female patients will be suplemented with inulin (15g/day) upon cyclofosfamide therapy. This supplementation will be performed daily for 21 days, it will start the day after the administration of cyclofosfamide (regardless the combination with other chemotherapeutic agents or the therapy round).
Inulin will be given as oral powder mixed in 250mL of water. In order to monitor adherence a food diary will be used as well as social networks (WhatsApp and Facebook). Moreover, hospital records of laboratory tests for albumin, transferrin and hemoglobin will be considered.
Intervention code [1] 296089 0
Treatment: Other
Comparator / control treatment
There will be a control group (n=19) that will receive maltodextrin instead of inulin for the same period of supplementation (21 days).
Control group
Placebo
