Olaparib Keeps Hereditary Breast Tumors in Check.

In the phase III OlympiAD study, tumors shrank in about 60% of women with BRCA mutation-associated metastatic breast cancer who received the PARP inhibitor olaparib compared with 29% who received chemotherapy; the median time to disease progression was 7 months compared with 4.2 months, respectively. These findings are the first to demonstrate that a PARP inhibitor can improve progression-free survival in metastatic, hereditary breast cancer. ©2017 American Association for Cancer Research.
