The aim of this study was to identify the frequency and spectrum of germline and somatic BRCA1/2 alterations in a group of Polish patients with ovarian serous carcinoma.
Our goal was to assess whether immunohistochemical analysis (IHC) for BRCA1 is an effective method for the detection of BRCA1 dysfunction in molecularly characterized high-grade ovarian serous carcinoma.
Mutations of TP53 and dysfunction of the Brca1 and/or Brca2 tumor-suppressor proteins have been implicated in the molecular pathogenesis of a large fraction of OSCs, but frequent somatic mutations in other well-established tumor-suppressor genes have not been identified.
