Breast Cancer with BRCA MutationsPoor Prognosis
1 Early onset of disease more years of lost life2 High prevalence of poorly differentiated high grade
and highly proliferative lesions more common in BRCA1 mutation cases
3 Higher prevalence of HR ndashve and TNBC 4 Altered sensitivity to systemic agents
bull to platinum and PARP inhibitorsbull to taxanes
5 Chemotherapy for early small tumors might improve the outcome

Take Home Messagebull Hereditary breast cancer is a unique disease with TN and HR
ndash phenotypes in gt 70 of cases and poor prognosis in vast majority of patients with compromised survival outcome
bull Deleterious BRCA mutations are associated with high risk of developing breast cancer with higher rates of local and contralateral failures than sporadic cases
bull Genetic counseling should be offered for high risk populationbull Screening mammography and MRI are complementarybull Prophylactic Bilateral Mastectomy 90 risk reductionbull Platinum compounds are key players in managementbull PARP inhibitors carry a promising change of disease
