Panelists discuss how the NCCN guidelines for risk stratification in HR+/HER2- early-stage breast cancer inform clinical decision-making, with an emphasis on biomarker testing, the use of tools like RSClin N+, and the evolving role of CDK4/6 inhibitors and adjuvant therapies. They also address challenges in risk assessment and the integration of newer treatment strategies, such as CDK4/6 inhibitors and PARP inhibitors in the early-stage setting.

With a focus on closing gaps in cancer care for underserved populations, Joseph A. Sparano, MD, FACP, always strives to put patients first—a quality that has become a hallmark of his research and career in oncology.

Sagar D. Sardesai, MBBS, discusses the phase 3 ELAINE-3 trial evaluating lasofoxifene plus abemaciclib in ESR1-mutant, ER-positive, HER2-negative breast cancer.

Lasofoxifene plus abemaciclib is set to be evaluated in ESR1-mutated ER+/HER2– metastatic breast cancer in the phase 3 ELAINEIII trial.

Dr. Laura Huppert presents key data from the DESTINY-Breast12 study, showcasing the effects of trastuzumab deruxtecan on health-related quality of life and neurological function in HER2+ metastatic breast cancer patients, with findings demonstrating preserved quality of life and neurological stability, regardless of brain metastasis status.

Rates of invasive cancer were noninferior when patients with low-risk ductal carcinoma in situ received active monitoring vs guideline concordant care.

Radiation therapy produced superior HRQOL outcomes and fewer toxicities vs endocrine therapy in older patients with stage I luminal-like breast cancer.

Ultra-sensitive tissue-free ctDNA testing showed that baseline ctDNA was associated with larger pathological tumor size in HR-positive breast cancer.

Elacestrant increased real-world TTNT for patients with ESR1-mutant HR-positive/HER2-negative breast cancer vs PFS from the phase 3 EMERALD trial.

Fixed-duration acalabrutinib combination improves PFS in CLL, imlunestrant ± abemaciclib boosts PFS in ESR1-mutated ER+ breast cancer, and more.

The risk of developing high-grade immune-related AEs was heightened among patients with breast cancer who were older and who had chronic kidney disease.

Albert Grinshpun, MD, MSc, discusses the utility of ctDNA as a predictive biomarker of endocrine therapy sensitivity in patients with HR+ breast cancer.

Erica L. Mayer, MD, MPH, discusses findings with neoadjuvant niraparib plus dostarlimab in ER-positive, HER2-negative, BRCA/PALB2-mutated breast cancer.

ctDNA was most frequently detected within 6 months post-treatment in patients with TNBC, aligning with the early recurrence pattern characteristic of the disease.

Treatment with atezolizumab and neoadjuvant chemotherapy followed by adjuvant atezolizumab did not improve EFS in triple-negative breast cancer.

Treatment with preoperative niraparib plus dostarlimab generated responses among patients with BRCA-mutant, ER-positive, HER2-negative breast cancer

Neoadjuvant camrelizumab paired with chemotherapy significantly improved pCR over chemotherapy alone in early or locally advanced TNBC.

Bora Lim, MD, of The University of Texas MD Anderson Cancer, and Stephanie Graff, MD, of Brown University Health, sit down with Chandler Park, MD, FACP, to discuss the latest abstracts in breast cancer presented during the 2024 San Antonio Breast Cancer Symposium.

Mariya Rozenblit, MD, discusses how genomic alterations and TMB influence the efficacy of immune checkpoint inhibitors in HR+ metastatic breast cancer.

Maxwell Lloyd, MD, discusses a real-world study of elacestrant outcomes based on prior treatment and ESR1 mutation status in HR+ breast cancer.

Palbociclib plus anti-HER2 and endocrine therapy improved progression-free survival in hormone receptor–positive, HER2-positive metastatic breast cancer.

Sara Hurvitz, MD, of Fred Hutch Cancer Center, and Neil Iyengar, MD, of Memorial Sloan Kettering Cancer Center, sit down with Chandler Park, MD, FACP, to discuss the latest abstracts in breast cancer presented during the 2024 San Antonio Breast Cancer Symposium.

Tamoxifen reduced the risk of invasive ipsilateral breast recurrence in patients with good-risk ductal carcinoma in situ.

Retrospective data showed there was no OS difference between 3 frontline CDK4/6 inhibitor combos in HR-positive breast cancer.

Patients with luminal B and HER2E breast cancer subtypes may have a greater PFS benefit with ribociclib plus endocrine therapy vs combination chemotherapy.
