Clinical Trial Summary

This project aims to decrease undesirable side effects and increase qulaity of life of aromatase inhibitors therapy in breast cancer survivors, by anti-inflammatory diet or supplementation.

Description:

With 2.1 million new breast cancer (BRC) cases each year globally, BRC is one of the biggest health challenges today. Available anticancer therapies have limited efficacy and are coupled with toxic side effects. Nutritional intervention can ameliorate undesirable effects, reduce exhaustion, psychological harm, and costs spent on treating these side effects. The proposed project AID aims to improve clinical outcome, quality of life (QoL) and survival rate in BRC patients on adjuvant endocrine therapy with aromatase inhibitors (AI) by nutritional interventions. In a three-arm randomised controlled nutritional trial involving 90 BRC patients who will receive either supplement or placebo pills (control group), or an anti-inflammatory diet for 4 months, along with the AI therapy, changes in nutritional status, QoL, biochemical and clinical parameters will be measured in comparison among three groups. The second goal is to establish cause-and-effect relationships among the clinical outcomes, nutritional status and biochemical parameters related to cancer, including inflammatory and redox status, plasma lipidome and polymorphism of fatty acid desaturase (FADS) genes. Introducing an effective nutritional intervention in BRC patients as an integral part of the multimodal therapeutic approach is the goal of this project.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Nutritional status	assessed through blood cells count	baseline, 4 months, 1 year
Primary	Nutritional status	assessed through body mass index-BMI	baseline, 4 months, 1 year
Primary	Nutritional status	assessed through body composition- lean tissue, fat tissue and body water (in kg)	baseline, 4 months, 1 year
Primary	Changes in Quality of life	assessed through the questionnaires FACT ES. The response scale is 5 point Likert-type scale (0- not at all, 4- very much).	baseline, 4 months
