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).

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).

Nicholas C. Turner, MD, PhD, of The Royal Marsden NHS Foundation Trust, discusses findings from the plasmaMATCH trial, which showed that circulating tumor DNA testing offers accurate tumor genotyping to identify patients with rare HER2 and AKT1 mutations and may enable matching them with targeted treatments (Abstract GS3-06).
Priyanka Sharma, MD, of the University of Kansas Medical Center, reviews new phase III data on adding oral fluoropyrimidine to adjuvant endocrine therapy, the current standard of care, in the setting of hormone receptor–positive, HER2-negative primary breast cancer (Abstract GS1-09).
Icro Meattini, MD, of the University of Florence, discusses study findings that showed the less-invasive partial-breast irradiation using intensity-modulated radiotherapy after surgery may be an acceptable choice for patients with early breast cancer, as it is cost-effective, safe, and efficacious when compared with whole-breast irradiation (Abstract GS4-06).
Ralph R. Weichselbaum, MD, of the University of Chicago, summarizes a plenary lecture in which he presented data that could guide future clinical strategies: studies supporting the basis and classification of oligometastatic disease, including breast cancer; and basic and clinical data on radioimmunotherapy (Abstract PL2).
Miguel Martín, MD, PhD, of the Gregorio Marañón Institute and GEICAM, discusses phase III study findings that showed no improvement in progression-free survival with palbociclib plus endocrine therapy vs capecitabine in patients with hormone receptor–positive/HER2-negative metastatic breast cancer whose disease progressed on aromatase inhibitors—although the drug combination was generally better tolerated than capecitabine (Abstract GS2-07).
Sara M. Tolaney, MD, MPH, of Dana-Farber Cancer Institute, discusses phase II findings on patients receiving T-DM1 monotherapy as adjuvant treatment for stage I HER2-positive breast cancer, a regimen associated with few recurrences in the study population (Abstract GS1-05).
