Study summary

To determine somatic and germline pathogenic variants in patients with denovo metastatic breast cancer in order to map the molecular/genetic characteristics of DN- MBC aiming in comprehending the biology and highlighting potential novel treatment options for the disease.

Read the detailed description

The value of this study is based on the fact that DN-MBC is rare, seems to be different from early and relapsed breast cancer and has not been studied as distinct disease. To achieve the objective of this study blood and tissue sample from patients diagnosed with DN-MBC will be further analyzed using next generation sequencing (NGS), in order to map the molecular/genetic characteristics of DN-MBC and to detect germline and somatic pathogenic variants. All the results will be associated with the clinicopathological characteristics of the patients.
