Introduction: About 5 - 10% of breast carcinomas are caused by genetic mutations. The most common genetic mutation that is involved in the development of this malignancy is a mutation in the tumor suppressor genes BRCA1/2 whose carriers have approximately a 70% lifetime risk of developing breast cancer. The prognosis of patients with BRCA1/2-asociated breast carcinoma, compared to patients with sporadic breast carcinoma is the subject of many studies with ambiguous results. Aim: The aim of the theoretical part of this work was to approach the issue of breast cancer and the most common genetic syndromes associated with it. In the practical part of this work a retrospective study was carried out in order to compare BRCA1/2 mutated breast cancer patients with non-mutated breast cancer patients in the tumor profile, methods of treatment and prognosis. Methods: We retrospectively analyzed the data of 134 patients who were tested for the presence of BRCA1/2 mutation at the Institute of Medical Genetics, University Hospital in Pilsen during the years 2013-2018 and at the same time were treated for early breast cancer at the University Hospital in Pilsen during the years 2000-2020. 32 patients were BRCA1 positive (24%), 10 BRCA2 positive (7%) and 92 without BRCA1/2 mutation (69%). The follow- up time was...
