Eleftherios P. Mamounas, MD, of Orlando Health Cancer Institute, discusses primary outcomes from the NRG Oncology/NSABP B-51/RTOG 1304 study of locoregional irradiation in patients with biopsy-proven axillary node involvement at presentation who become pathologically node-negative after neoadjuvant chemotherapy (Abstract GS02-07).
Nadia Harbeck, MD, PhD, of LMU University Hospital and Ludwig Maximilian University of Munich, and Daniel Kates-Harbeck, of the West German Study Group and an MD Candidate at Ludwig Maximilian University of Munich, discuss a learning-based neural network developed by Mr. Kates-Harbeck to predict treatment outcomes in early breast cancer as well as potentially other tumor types (Abstract PO 04 1-10).
Luca Gianni, MD, of Milan’s Fondazione Michelangelo, discusses findings from the APTneo Michelangelo trial, which showed that adding atezolizumab to chemotherapy and trastuzumab plus pertuzumab did not significantly increase the rate of pathologic complete response (pCR) in women with HER2-positive breast cancer. An exploratory analysis showed that adding atezolizumab to neoadjuvant anthracycline and cyclophosphamide followed by HPCT (trastuzumab + pertuzumab and chemotherapy) led to higher pCR rates than HPCT and atezolizumab (Abstract LBO1-02).
Oleg Gluz, MD, of the West German Study Group and Breast Center Niederrhein, discusses the impact of age and ovarian function suppression in response to preoperative endocrine treatment for both pre- and postmenopausal patients with early-stage breast cancer. He describes ways in which the outcome data of the ADAPTcycle study might influence clinical decisions (Abstract LBO1-05).
Barbara Pistilli, MD, of France’s Gustave Roussy, discusses a phase Ib analysis from the CAPItello-292 study, which showed capivasertib plus palbociclib plus fulvestrant was tolerable at all dose levels in heavily pretreated patients with hormone receptor–positive, HER2-negative advanced breast cancer. As data collection continues, evidence of clinical activity has been observed in patients treated with the recommended phase III dose (Abstract PS12-09).
Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses an exploratory analysis of CheckMate 7FL which showed that patients with PD-L1–positive, high-risk, estrogen receptor–positive, HER2-negative primary breast cancer may achieve substantial pathologic complete response rates with the addition of nivolumab to neoadjuvant chemotherapy (Abstract GS01-01).
Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses recent data showing that for patients with stage I/II triple-negative breast cancer, 12 weeks of a neoadjuvant nonanthracycline chemotherapy regimen with nivolumab may be efficacious with either concurrent or lead-in nivolumab. Those with immune-enriched tumors had high pathologic complete response rates, identifying a subpopulation for whom a 12-week anthracycline-free chemotherapy regimen with nivolumab may be appropriate (Abstract LBO1-03).
Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses phase III findings from the KEYNOTE-756 study, which showed that adding pembrolizumab to chemotherapy increases the pathologic complete response rate and lowers the residual cancer burden in patients with early-stage, high-risk ER-positive or HER2-negative breast cancer (Abstract GS01-02).
Daniel G. Stover, MD, of The Ohio State University Comprehensive Cancer Center, discusses a biomarker analysis from the PALLAS adjuvant trial, which compared 2 years of the CDK4/6 inhibitor palbociclib with endocrine therapy vs endocrine therapy alone, as adjuvant treatment for patients with stage II–III hormone receptor–positive, HER2-negative breast cancer. The genomic subtype PAM50 was defined in the protocol of the PALLAS trial as the primary biomarker for analysis of prediction and prognosis (Abstract GS03-07).
Senthil Damodaran, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses final results from the FOENIX-MBC2 study of the efficacy and safety of futibatinib in patients with locally advanced or metastatic hormone receptor–positive, HER2-negative breast cancer harboring high-level FGFR1 gene amplification. Futibatinib plus fulvestrant showed antitumor activity in those whose disease had progressed on prior CDK4/6 inhibitors (Abstract RF01-04).
Nicholas C. Turner, MD, PhD, of The Royal Marsden Hospital NHS Foundation Trust, and the Institute of Cancer Research, London, discusses the monarchE trial, which evaluated molecular profiling of archived primary tumor tissue from patients with hormone receptor–positive, HER2-negative, node-positive, high-risk early-stage breast cancer and its potential association with clinical outcomes. Adjuvant abemaciclib plus endocrine therapy (ET) maintained invasive disease–free survival benefit compared with ET alone across all molecular subtypes as measured by RNA sequencing (Abstract GS03-06).
Gabriel N. Hortobagyi, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from the NATALEE trial, which continued to demonstrate improved invasive disease–free survival with ribociclib plus a nonsteroidal aromatase inhibitor (NSAI) over a NSAI alone in patients with hormone receptor–positive, HER2-negative early breast cancer (Abstract GS03-03).
Targeted treatment with ribociclib plus hormone therapy provided significant invasive disease–free survival benefits in patients with early-stage hormone receptor–positive, HER2-negative breast cancer at risk of disease recurrence. Results from the phase III NATALEE trial, led by researchers at The ...
Final overall survival results from the MONARCH 3 trial were reported in a late-breaking presentation during the 2023 San Antonio Breast Cancer Symposium (Abstract GS01-12). MONARCH 3 evaluated abemaciclib in combination with an aromatase inhibitor (AI) compared with an AI alone as initial...

Nadia Harbeck, MD, PhD, of Munich’s LMU University Hospital and the Ludwig Maximilian University, discusses an interim analysis of the monarchE trial on adjuvant abemaciclib plus endocrine therapy for patients with hormone receptor–positive, HER2-negative, high-risk early breast cancer. The data showed this regimen continued to reduce the risk of developing invasive and distant disease recurrence well beyond the completion of treatment. The improvement at 5 years is consistent with a carryover effect and further supports the use of the CDK4/6 inhibitor abemaciclib in this population (Abstract LBA17).

This is Part 3 of Updates in Early-Stage Breast Cancer,, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Erika Hamilton, Michael Danso, and Komal Jhaveri discuss the management of early triple-negative breast cancer. The patient is a 54-year-old Black female who notices nipple retraction in the left breast. Ultrasound reveals a 3.8-cm mass, and biopsy confirms estrogen receptor 0, progesterone receptor 0, HER2 1+ by IHC, FISH nonamplified, grade 3 disease, with a high Ki-67 of 60%. She undergoes lymph node sampling, which is also positive for invasive ductal carcinoma. The faculty review neoadjuvant chemotherapy options for patients with node-positive, triple-negative breast cancer, whether PD-L1 status has any impact in the early-stage setting, the importance of genetic testing, and the clinical implications of the KEYNOTE-522 and OlympiA trials.
This is Part 2 of Updates in Early-Stage Breast Cancer,, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Erika Hamilton, Michael Danso, and Komal Jhaveri discuss the management of early node-negative HER2-positive breast cancer. The patient is a 53-year-old White female with a right breast abnormality noted on screening mammogram. The mass is biopsied, revealing a 1.1-cm lesion that is estrogen receptor positive, progesterone receptor negative, HER2 amplified. Due to the small size, she undergoes lumpectomy and is found to have 1.2-cm invasive ductal carcinoma that is HER2-amplified with zero out of two lymph nodes involved. In the conversation that follows, the faculty discuss the impact of tumor size on adjuvant treatment selection for patients with node-negative HER2-positive breast cancer, which patients are candidates for neoadjuvant HER2-directed therapy, and the clinical implications of the APT and KATHERINE trials.
