“Outcomes for patients with HER2-positive breast cancer did not differ when treated with sequential chemotherapy plus trastuzumab compared with a concurrent approach, according to a new phase III trial.
” ‘The effectiveness of trastuzumab with chemotherapy in the neoadjuvant setting is evident; however, the cardiac safety of trastuzumab combined with anthracyclines has been questioned,’ wrote study authors led by Kelly K. Hunt, MD, of the University of Texas MD Anderson Cancer Center in Houston.”
“Developing predictive biomarkers will be key to treating patients with triple-negative breast cancer (TNBC), especially when choosing a targeted therapy, said Banu K. Arun, MD.
“In a presentation during the 2018 OncLive® State of the Science Summit™ on Breast Cancer, Arun said there is evidence that PARP inhibitors as well as immunotherapy in combination with various agents may be effective in women with TNBC and BRCA1-related breast cancers, but the science isn’t there yet.”
“A trial assessing the alpha-specific PI3K inhibitor alpelisib with fulvestrant met its primary endpoint of PFS among patients with hormone receptor-positive, HER-2-negative advanced breast cancer with a PIK3CA mutation, according to the agent’s manufacturer.
“The phase 3 global, double-blind SOLAR-1 study included 572 women and men with PIK3CA-mutated hormone receptor-positive, HER-2-negative advanced or metastatic breast cancer that progressed on or following prior aromatase inhibitor treatment with or without a CDK4/6 inhibitor.”
“The now-published results from the EMBRACA study confirm that talazoparib (Pfizer), a poly-adenosine diphosphate-ribose polymerase (PARP) inhibitor, prolongs progression-free survival (PFS) in patients with advanced BCRA-positive breast cancer compared with single-agent chemotherapy alone, and that it also significantly improves quality of life.
” ‘This is the largest randomized trial in BRCA mutation carriers [ever undertaken] and demonstrates PARP efficacy,’ Jennifer Litton, MD, associate professor in the Department of Breast Medical Oncology, University of Texas MD Anderson Cancer Center, Houston, told Medscape Medical News in an email.”
“ASCO and Friends of Cancer Research (Friends) have submitted recommended language to the U.S. Food and Drug Administration (FDA) for five guidance documents on ways to broaden eligibility criteria for cancer clinical trials. The recommendations are part of an ASCO and Friends collaboration to broaden eligibility for participating in clinical trials by addressing five specific areas: minimum age requirements for trial enrollment, HIV/AIDS status, brain metastases, organ dysfunction, and prior and concurrent malignancies.”
“Patients with ductal carcinoma in situ (DCIS) are often treated with radiation after lumpectomy, although it has remained unclear whether this can reduce the risk of dying from this noninvasive form of breast cancer. A new study published Friday said that the combination of the 2 treatments was associated with a small benefit in reduced risk of breast cancer death compared with lumpectomy or mastectomy alone.”
“As a medical oncologist and investigator, Rinath M. Jeselsohn, MD, focuses on the detection and clinical implications of ESR1 mutations in estrogen receptor–positive breast cancer. She is a member of the research team in the lab of Myles A. Brown, MD, at Dana-Farber Cancer Institute in Boston, Massachusetts, where investigators are seeking to elucidate the factors underlying the mechanisms of hormone responsiveness, particularly steroid hormone receptors, in human cancers.
“Jeselsohn, who has led numerous studies into ESR1 mutations, discussed the field in an interview with OncologyLive®.”
“First-line atezolizumab plus nab-paclitaxel improved PFS compared with placebo among patients with metastatic or unresectable locally advanced triple-negative breast cancer, according to interim results from the IMpassion130 trial released by the manufacturer.
“Researchers observed prolonged PFS in both the intention-to-treat population and the PD-L1-positive population.”
“In an analysis of long-term outcomes in the SOFT and TEXT trials reported at the 2018 ASCO Annual Meeting and in The New England Journal of Medicine, Francis et al found that the addition of ovarian suppression to adjuvant tamoxifen significantly improved 8-year rates of disease-free and overall survival vs tamoxifen alone among premenopausal women with breast cancer; risk of recurrence was further reduced with exemestane plus ovarian suppression.
“Initial reports showed that 5-year rates of recurrence were significantly lower among premenopausal women who received the aromatase inhibitor exemestane plus ovarian suppression vs tamoxifen plus ovarian suppression, with the addition of ovarian suppression to tamoxifen not significantly improving recurrence risk vs tamoxifen alone.”
