Clinical Trial Summary

FATLAS is a prospective, interventional, non Investigational Medicinal Product (IMP) study aiming to characterize the micro- and macroenvironment of breast cancer according to patient adiposity in different histological and molecular subtypes. The macroscopic profiling of the patient's adiposity will be based on Body Mass Index (BMI), bioimpedance analysis and waist-to-hip ratio. Blood samples will be taken for lipidomic analyses and for hormonal and immuno assays. Microscopic profiling of adiposity and inflammation will be done on fresh frozen (FF) and Formalin-Fixed Paraffin-Embedded (FFPE) samples from the tumour resection specimen and will consist of histological characterization, immuno assays, multiplex immunohistochemistry, DNA sequencing and single nuclei RNA sequencing both in the tumour and in adjacent normal mammary tissue.
