Case Report of Complete Response to Olaparib in a Patient with Breast Cancer Brain Metastases.

ABSTRACT:

Introduction

Breast cancer is the second most common cause of central nervous system (CNS) metastases. It has been shown that the median time from breast cancer diagnosis to CNS metastasis is 30.9 months and that the overall median survival after metastasis is extremely poor at 6.8 months. Although treatment options for ErbB2 Receptor Tyrosine Kinase 2 (ERBB2)-positive breast cancer brain metastasis (BCBM) have been reported, effective treatment options for ERBB2-negative BCBM, which has one of the worst prognoses, are limited. Olaparib is one of the standard treatments for germline BRCA1/2 mutated (gBRCA1/2mt), ERBB2-negative, metastatic, or recurrent breast cancer. However, there is minimal existing evidence to evaluate the efficacy of olaparib in BCBM.
