Treatment discontinuation due to toxicity was less frequent with olaparib (Lynparza) monotherapy compared with chemotherapy in patients with HER2-negative metastatic breast cancer and a germline <em>BRCA</em> mutation in the phase III OlympiAD study.

In findings from the phase III GeparSepto trial presented during the 2017 San Antonio Breast Cancer Symposium, long-term disease-free survival rates were improved with neoadjuvant nab-paclitaxel (Abraxane) compared with standard paclitaxel in patients with high-risk early breast cancer.

Survival rates improved with nab-paclitaxel (Abraxane) therapy compared with paclitaxel in patients with triple-negative breast cancer (TNBC) more than in other patient subsets, according to findings from a post-hoc analysis from the CALGB 40502/NCCTG N063H clinical trial.&nbsp;

Results of a&nbsp;prospective clinical trial demonstrated that the detection of positive circulating tumor cells in the blood 5 years after hormone receptor-positive, HER2-negative breast cancer diagnosis was&nbsp;associated with an increased risk for late recurrence.

Treatment with a&nbsp;gonadotropin-releasing hormone analog could potentially preserve fertility and protect ovarian function in premenopausal woman being treated with chemotherapy for early-stage breast cancer, according to the results of a meta-analysis presented at the 2017 San Antonio Breast Cancer Symposium.

Results of the phase III SOLD trial maintained the benefit of 12 months of adjuvant treatment with trastuzumab (Herceptin) for patients with early stage HER2-positive breast cancer, as the trial failed to demonstrate noninferiority for 9 weeks of trastuzumab versus the standard 1-year period, when added to chemotherapy.&nbsp;

Disease-free survival&nbsp; is maintained in women with postmenopausal hormone receptor-positive breast cancer treated with aromatase inhibitors, even when the treatment is only given for 2 years in comparison with the standard 5 years of additional aromatase inhibitor therapy, according to findings from the phase III ABCSG-16 trial presented at the 2017 San Antonio Breast Cancer Symposium.&nbsp;

Julie Nangia, MD, assistant professor of Medicine, Baylor College of Medicine, discusses getting genetic testing for patients. While the NCCN has guidelines of who should be tested, it may also be possible for physicians to write a letter of medical necessity for other people, such as Ashkenazi Jewish women, who have higher rates of BRCA mutations.

Early-stage breast cancer recurrence and mortality was reduced by shortening the intervals between chemotherapy cycles or administering&nbsp;the drugs sequentially&nbsp;compared with&nbsp;standard dosing techniques, according to meta-analysis results presented at the 2017 San Antonio Breast Cancer Symposium.

Mothaffar F. Rimawi, MD, associate professor and director of clinical research at the Lester and Sue Smith Breast Center at Baylor College of Medicine, discusses the&nbsp;NSABP B-47 study, which explored&nbsp;the value of trastuzumab (Herceptin) plus standard adjuvant chemotherapy in breast cancer patients with low levels of HER2 protein.

An overall disease control rate of 45% was achieved with sacituzumab govitecan (IMMU-132) therapy in patients with heavily pretreated metastatic triple-negative breast cancer (mTNBC), according to updated findings of a study presented at the 2017 San Antonio Breast Cancer Symposium (SABCS).&nbsp;
