Breast Neoplasms, Male

PALMARES-2 is a retrospective/prospective, observational, multicenter, population-based study, aiming at providing real-world evidences on HR+/HER2- aBC patients treated with first-line CDK4/6i plus ET. The present study has the objective to collect data coming from different sources, i.e. RWD, medical images and biological samples, from patients treated with CDK4/6i as first-line of therapy for HR+/HER2- aBC. In consideration of the complexity of data collected and different objectives of the study, this master protocol foresees different sub-studies, which encompasses different methodologies for data collection, data extraction and analyses.

It is believed that the use of organoids derived from male breast tumors can be of fundamental support for the definition of the molecular mechanisms underlying the onset of the tumor. Furthermore, the development of such preclinical models could be of significant support for the identification of specific personalized and ad hoc therapeutic treatments for male pathology.
