Brief Summary

Extracellular vesicles (EVs) are lipid bilayer-delimited particles, naturally released from the cells and mediators of intercellular cross-talk. In breast cancer (BC), EVs seem to be involved in the tumor microenvironment's shaping, in cancer cells invasion and in the set-up of metastasis. Clinical studies have provided initial evidence that EVs may have a prognostic and predictive value in breast cancer. Considering their presence in body fluids and their minimally invasive assessment through blood sampling, EVs could be liquid biopsy-derived biomarkers. Their quantification could be a complex challenge, requiring complicated and time-consuming pre-analytical procedures of EVs isolation. A new method for the detection of tumor-derived-EVs associated proteins is based on the use of Single Molecule Array (SiMoA), a digital ELISA technology able to detect and quantify extremely low concentrations of target proteins or particles. The aim of this study is to evaluate how this new technology can allow the quantification EVs plasma levels in patients affected by BC, providing useful diagnostic and prognostic information about the efficacy of the neoadjuvant treatment.

Outcome Measures

Primary Outcomes (2)

  • EVs levels

    Measurement of plasma EVs levels (by Simoa-Elisa) in BC patients at the moment of diagnosis and comparison between EVs concentration in BC patients' and healthy controls.

    78 months

  • EVs levels in time

    Evaluation of tumor-related EVs as predictive markers of neoadjuvant treatment efficacy in BC patients. This will be conducted comparing EVs level during different collected times

    78 months

Study Arms (2)

Breast cancer patients candidate for neoadjuvant chemotherapy

Female patients diagnosed with breast cancer, at any TNM stage, who are candidate to neoadjuvant treatment.

Healty control

Control group (sex and age matched): healthy volunteers, not affected by breast cancer (with negative mammography, breast ultrasound or breast examination within 12 months of the study enrolment).
