A weekly schedule of nab-paclitaxel as part of neoadjuvant chemotherapy significantly improved pathologic complete response compared with nab-paclitaxel given 2 weeks out of every 3 weeks (2/3) in patients with primary breast cancer, with a greater magnitude of benefit in patients with...
As reported in The Lancet by Timothy J. Whelan, BM, BCh, and colleagues, the phase III noninferiority RAPID trial has shown that external-beam accelerated partial-breast irradiation is noninferior to whole-breast irradiation in reducing risk of local recurrence after breast-conserving surgery in...
Neoadjuvant systemic therapy can shrink tumors in patients with breast cancer and, in some cases, allow patients to receive breast-conserving therapy who would otherwise require mastectomy. However, in the United States, about 55% of patients who become eligible for breast-conserving therapy after...
A new study shows that a test physicians commonly use to guide chemotherapy for patients with breast cancer after surgery may also help them decide whether radiation therapy may be of benefit. Results published by Wendy A. Woodward, MD, PhD, and colleagues in JAMA Oncology suggest patients with an...
Lack of insurance coverage is a major cause of delayed breast cancer screening and treatment among minority women, which could lead to a decrease in a patient’s chance of survival. Nearly half of the disparity in later-stage diagnosis between non-Hispanic white women and black, Hispanic, and...
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses a retrospective analysis on the effectiveness of the VENTANA PD-L1 SP142 assay, the Dako 22C3 assay, and the VENTANA SP263 assay as predictors of response to atezolizumab plus nab-paclitaxel in patients with metastatic triple-negative breast cancer (Abstract PD1-07).
As reported in the Journal of Clinical Oncology by Louis Fehrenbacher, MD, and colleagues, the phase III NSABP B-47/NRG Oncology trial has shown no invasive disease–free survival benefit with the addition of trastuzumab to adjuvant chemotherapy therapy in patients with HER2-negative breast cancer...
As reported in the Journal of Clinical Oncology by Ambrosone et al, an analysis of the SWOG S0221 trial population suggests that use of antioxidant and nonantioxidant dietary supplements, but not multivitamins, before and during adjuvant chemotherapy may be associated with poorer treatment outcomes ...
As reported in The Lancet by Frank A. Vicini, MD, and colleagues, 10-year follow-up in the phase III NSABP B-39/RTOG 0413 equivalence trial has shown that accelerated partial-breast irradiation did not achieve equivalence to whole-breast irradiation in preventing local recurrence in women receiving ...

Terry P. Mamounas, MD, MPH, of Orlando Health UF Health Cancer Center, discusses 10-year results from NRG Oncology/NSABP B-42, which showed that, for postmenopausal women with hormone receptor–positive breast cancer who have completed previous adjuvant therapy with an aromatase inhibitor or with tamoxifen followed by an aromatase inhibitor, extended treatment with letrozole improved disease-free survival (Abstract GS4-01).
Luca Gianni, MD, of the Fondazione Michelangelo, discusses findings from the NeoTRIP trial on pathologic complete response to neoadjuvant treatment with or without atezolizumab in triple-negative, early high-risk, and locally advanced breast cancer (Abstract GS3-04).
Hongchao Pan, PhD, of the University of Oxford, discusses an analysis of 86,000 women in the Early Breast Cancer Trialists’ Collaborative Group database, which showed that the risk of distant recurrence 20 years after a diagnosis of node-negative, estrogen receptor–negative early-stage breast cancer in women who discontinued endocrine therapy at 5 years is likely to be about a third lower now than in his group’s previous report (Abstract GS2-04).
Nadine M. Tung, MD, of Beth Israel Deaconess Medical Center, discusses cisplatin vs doxorubicin/cyclophosphamide (AC) as neoadjuvant treatment in BRCA-mutation carriers with HER2-negative breast cancer. Although cisplatin as a single agent shows activity in this setting, the pathologic complete response with this agent alone is not higher than that with standard AC chemotherapy (Abstract GS6-03).
Ivana Sestak, PhD, of Queen Mary University of London and the Centre for Cancer Prevention, discusses study findings that confirm the prognostic ability of the Clinical Treatment Score at 5 years (CTS5) for late distant recurrence, specifically for patients older than 50 years and/or for those deemed to have intermediate- or high-risk hormone receptor–positive, HER2-negative, node-negative breast cancer. The CTS5 is less prognostic in women younger than 50 who received 5 years of endocrine therapy alone (Abstract GS4-03).
Marie-Jeanne T.F.D. Vrancken Peeters, MD, PhD, of the Netherlands Cancer Institute, discusses an interim study analysis showing that ultrasound-guided core biopsies of the breast in patients with excellent response on MRI after neoadjuvant systemic therapy may not be accurate enough to safely select patients with pathologic complete response for omission of surgery (Abstract GS5-06).
Ariella B. Hanker, PhD, of UT Southwestern Medical Center, discusses data showing that breast cancers expressing co-occurring HER2 and HER3 mutations may require the addition of a phosphoinositide 3-kinase alpha inhibitor to a HER2 tyrosine kinase inhibitor (Abstract GS6-04).

Madeleine M.A. Tilanus-Linthorst, MD, PhD, of Erasmus University, reports data from the first randomized trial comparing MRI breast cancer screening with mammography in women with a familial risk. Because MRI screening detected cancer at an earlier stage, it might reduce the use of adjuvant chemotherapy and decrease breast cancer–related mortality (Abstract GS4-07).
Joerg Heil, MD, PhD, of the University Hospital Heidelberg, discusses findings on how accurately this technique can diagnose residual disease and pathologic complete response after neoadjuvant chemotherapy in patients with breast cancer. These data may help tailor, de-escalate, and potentially avoid unnecessary surgeries (Abstract GS5-03).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses trial data on margetuximab plus chemotherapy, which improved progression-free survival in patients with previously treated HER2-positive metastatic breast cancer when compared with trastuzumab plus chemotherapy. Maturing data comparing overall survival also provides new insights (Abstract GS1-02).
Javier Cortes, MD, PhD, of the IOB Institute of Oncology, discusses study findings that suggested pembrolizumab offered a prolonged survival benefit compared to chemotherapy for a subset of patients with previously treated metastatic triple-negative breast cancer. In the trial, high tumor-infiltrating lymphocytes were significantly associated with better clinical outcomes with the checkpoint inhibitor.
Joseph Sparano, MD, of the Montefiore Medical Center, discusses three challenges: How can gene-expression profiles and other diagnostic tests be used to guide the use of adjuvant systemic therapy? Is it time to reappraise active surveillance? Are there diagnostic and therapeutic strategies that can identify tumors at highest risk of metastasis, and novel therapies that can block the spread of disease?
Milan Radovich, PhD, of Indiana University School of Medicine, discusses trial findings that show patients with triple-negative breast cancer who are at high risk of relapse after receiving preoperative chemotherapy can be risk-stratified based on the presence of minimal residual disease as determined by circulating tumor DNA and circulating tumor cells (Abstract GS5-02).
Belinda Kingston, MB ChB, of the Institute of Cancer Research London, discusses next-generation sequencing results from the plasmaMATCH trial, including the incidence of gene alterations overall, as well as the associations with clinical and pathologic features that may help direct treatment decisions (Abstract GS3-07).
Tari A. King, MD, of Brigham and Women’s Hospital and Dana-Farber/ Brigham and Women’s Cancer Center, discusses retrospective findings from the AURORA U.S. Network on molecular differences between primary tumors and metastases, a better understanding of which may help lead to more effective treatment of metastatic breast cancer (Abstract GS3-08).
Rashmi K. Murthy, MD, of The University of Texas MD Anderson Cancer Center, discusses data on the efficacy and safety of tucatinib, trastuzumab, and capecitabine, a treatment regimen under investigation for patients with advanced HER2-positive metastatic breast cancer refractory to standard-of-care regimens (Abstract GS1-01).
