Detailed Description
Identification and inclusion in the study of patients affected by metastatic triple-negative breast cancer mTNBC, treated with sacituzumab govitecan SG as indicated at the participating centers.

Histological and biomolecular characteristics will be evaluated both on the tumor at diagnosis and on tissue resulting from biopsy of the metastatic site, where available. Otherwise, the analyzes will come anyway carried out on the most recent and available tumor tissue, whether deriving from primary tumor or site metastatic.

The search for biomarkers predictive of efficacy/tolerability will be carried out on tumor tissue (where possible both primary and metastatic) and on circulating plasma collected at two separate time points (T0 and T1).

Biomolecular characterization on the biological material of the enrolled patients (tumor tissue and plasma) will be carried out at the end of the study.

The feasibility of organoid development and single-cell sequencing will be evaluated on a small subgroup of patients, among those enrolled at the coordinating center, considering the need for tumor tissue prepared fresh for both methods.
