AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for postmenopausal women, either healthy or with early luminal breast cancer, who are of normal weight or have overweight or obesity.
- Sex
- Women only
- Disease stage
- Healthy women, or women with luminal subtype breast cancer, stages I-II, who need tumor surgery.
- Earlier treatment
- Women with breast cancer must not need treatment before surgery. Healthy women must have stable weight over the last 3 months (±5%) and no current weight loss treatment.
- Biomarker or test result
- Breast cancer must be the luminal subtype.
Main reasons for not taking part
- Breast cancer above stage II or another type of breast cancer
- Needing treatment before surgery (women with breast cancer)
- Personal history of cancer (healthy group)
- Bariatric surgery or current weight loss treatment (healthy group)
- Diabetes treatment or hormone replacement therapy (healthy group)

Unraveling the Role of Pro-Resolving Lipid Mediators of Inflammation and Their Receptors in Obesity-Associated Diseases: New Therapeutic Approaches for Maresin 1 (RESOLBE)
The main objective of this project is to determine the possible association between the levels of certain bioactive lipids, which the body produces from dietary fatty acids, and tumor characteristics in breast cancer patients, as well as their relationship with overweight/obesity.
Specific objectives are:
* To analyse anthropometric and body composition changes. * To evaluate physical activity level. * To determine dietary profile. * To determine the adherence to Mediterranean dietary pattern. * To assess the quality of life. * To determine levels of specialized pro-resolving lipid mediators
The target sample size is 60 subjects. Participants will be allocated in four groups:
* Group 1: Postmenopausal healthy women with overweight/obesity (n=15) * Group 2: Postmenopausal healthy women with normoweight (n=15) * Group 3: Postmenopausal women with breast cancer and overweight/obesity (n=15) * Group 4: Postmenopausal women with breast cancer and normoweight (n=15)
Inclusion: Postmenopause (al least 1 year); Normoweight or overweight/obesity; No personal history of cancer; Stable weight over the last 3 months (±5%); Willing to sign the informed consent and comply with all study procedures; Postmenopause (at least 1 year); Normoweight or overweight/obesity; Luminal subtype breast cancer, stages I-II, who require tumor resection and do not require preoperative treatment; Willing to sign the informed consent and comply with all study procedures.
Exclusion: Current weight loss treatment (diet, supplementation, surgery, others...); Bariatric surgery; Surgical interventions resulting in permanent sequelae of the gastrointestinal tract; Personal history of cancer; Diabetes treatment and hormone replacement therapy; Relevant functional or structural abnormalities of the gastrointestinal tract, such as malformations, angiodysplasias, active peptic ulcers, chronic inflammatory or malabsorption diseases, hiatal hernia, chronic reflux, etc; Liver disease, except for non-alcoholic fatty liver disease; Cognitive and/or psychiatric impairment; Poor compliance or difficulty following study procedures; BREAST CANCER PARTICIPANTS:; Luminal subtype breast cancer stages over than II or other type of breast cancer; No stable pharmacological treatment for at least 3 months; High alcohol intake, more than 14 units per week for women and 20 units per week for men; Require preoperative treatment.
