Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Development and validation of an integrated testing strategy for simultaneous detection of ESR-1 and gBRCA mutations via liquid biopsy in HR+/HER2- metastatic breast cancer (mBC) patients, and the creation of a digital gene library to support an evidence-based diagnostic algorithm

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Breast cancer is the most prevalent type of tumor and the primary cause of cancer-related deaths among women globally (1). Approximately two-thirds of these tumors express hormone receptors (HR) and lack HER2 overexpression and/or amplification (2). Throughout treatment, resistance frequently develops, with underlying mechanisms that remain largely undefined (3).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants must have a confirmed diagnosis of estrogen receptor-positive (ER+) and/or progesterone receptor-positive (PgR+) breast cancer through histological and/or cytological examination by the local laboratory Participants must exhibit HER2-negative breast cancer

1. or 2+). If IHC is 2+, a negative in situ hybridization (Fluorescent in situ hybridization (FISH), Chromogenic in situ hybridization (CISH), or Silver-enhanced in situ hybridization (SISH)) test is required by local laboratory testing.

* Participants should be in an advanced or metastatic setting including both those prior to the initiation of treatment for metastatic disease and those who experienced progression following treatment with cyclin-dependent kinases (CDK)4/6 inhibitors. However, the primary tumor should be treated according to the standard of care.
* Written informed consent must be signed and dated by the patient and the investigator prior to inclusion.

Exclusion Criteria

* Unable to provide written informed consent
