Experience with olaparib in a patient with luminal HER2-positive metastatic breast cancer
Hereditary breast cancer (BC) accounts for about 5-10% of cases. BRCA-associated tumors have been identified as a separate group of malignant neoplasms with distinctive clinical manifestations and specific treatment features. Understanding of biological mechanisms leading to cancer in BRCA1/2 mutation carriers and discovery of potential molecular targets, such as poly (ADP-ribose) polymerase (PARP), involved in base excision repair mechanisms, led to the development of a new class of targeted drugs belonging to the PARP inhibitors group. PARP inhibition leads to the preservation of single-stranded DNA breaks, the arrest of the replication fork, and the realization of the “synthetic lethality” phenomenon due to the inability to repair double-stranded DNA breaks by homologous recombination in cells with mutations in the BRCA1/2 genes. Two randomized trials OlympiAD and EMBRACA evaluated and proved the effectiveness of PARP inhibitors in patients with metastatic BRCA-mutated HER2-negative breast cancer in comparison with standard chemotherapy. At the same time, data on the potential use of PARP inhibitors for the treatment of BRCA-mutated HER2-positive breast cancer patients are extremely limited. This article presents a clinical example of the use of olaparib in a patient with BRCA-mutated HER2-positive metastatic breast cancer..
