This is Part 1 of The Role of Oral SERDs in Metastatic Breast Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this roundtable. In this video, Drs. Komal Jhaveri, Erika Hamilton, and Aditya Bardia discuss the treatment of a 61-year-old female patient who presents with bone pain 18 months after completion of adjuvant aromatase inhibitor therapy for an enlarged, suspicious axillary lymph node. A computed tomography scan shows numerous liver and bone metastases, and a liver biopsy confirms estrogen receptor–positive, progesterone receptor–negative, HER2-negative carcinoma consistent with breast primary. Circulating tumor DNA testing reveals an ESR1 Y537S mutation, and she has no BRCA1/2 mutations. The patient has a history of ventricular tachycardia and bipolar disorder, both controlled with medications known to cause QTc prolongation. In the conversation that follows, the faculty review first-line treatment options for this patient with ESR1 Y537S–mutated metastatic breast cancer, including selective estrogen receptor degraders (SERDs) both alone and in combination with CDK4/6 inhibitors, as well as the impact of her comorbidities on treatment selection. They also review the recent results of SERENA-6 and discuss whether they would be applicable to this patient.
Early detection of an ESR1 mutation, leading to a switch of endocrine therapy, led to an almost doubling in progression-free survival in the SERENA-6 trial, the global registrational study in patients with metastatic breast cancer for the investigational oral selective estrogen receptor degrader...
In the phase III DESTINY-Breast09 trial, first-line treatment with the antibody-drug conjugate fam-trastuzumab deruxtecan-nxki (T-DXd) plus the monoclonal antibody pertuzumab significantly delayed disease progression by more than 1 year—nearly doubling the time of disease control—over standard...

This is Part 3 of Novel Therapies for HER2-Positive Breast Cancer Brain Metastases, a three-part video roundtable series. Scroll down to watch the other videos from this roundtable. In this video, Drs. Carey Anders, Rani Bansal, and Sarah Sammons discuss the treatment of a patient with a history of ER/PR-negative, HER2-positive de novo metastatic breast cancer to the liver and brain. The 39-year-old patient initially responded well to systemic therapy and localized brain treatments but later developed symptomatic HER2-positive leptomeningeal disease (LMD), confirmed by brain MRI and lumbar puncture. In the conversation that follows, the faculty review effective systemic therapies like trastuzumab deruxtecan and the HER2CLIMB regimen of tucatinib, capecitabine, and trastuzumab. They discuss current approaches to LMD, including radiation therapy (with considerations for proton-based strategies to preserve cognitive function) and emphasize the crucial role of early palliative care for symptom management and support when dealing with LMD.
A common germline variant in the proprotein convertase subtilisin/kexin type 9 (PCSK9) (rs562556, V474I) gene rather than a mutation in a breast cancer tumor may be the driving force in significantly increasing the risk of breast cancer metastasis and reducing survival in women with the disease....
This is Part 1 of Novel Therapies for HER2-Positive Breast Cancer Brain Metastases, a three-part video roundtable series. Scroll down to watch the other videos from this roundtable. In this video, Drs. Carey Anders, Rani Bansal, and Sarah Sammons discuss the treatment of a patient with a cT2N1, grade 3, ER/PR/HER2-positive invasive ductal carcinoma. The 35-year-old female patient is premenopausal and achieved a pathologic complete response (pCR) after standard neoadjuvant chemotherapy, lumpectomy, and radiation. She began 1 year of ovarian suppression, aromatase inhibitor, and trastuzumab plus pertuzumab, but in the final month of her adjuvant treatment, she developed dizziness and nausea. Despite pCR, patients with HER2-positive localized breast cancer face a higher risk of intracranial recurrence (approximately 10%–12%), often without extracranial disease. In the conversation that follows, the faculty review treatment considerations for this patient—including when to consider neurosurgical resection, focused radiation therapy, or other systemic therapies—and discuss ongoing trials seeking to potentially prevent intracranial recurrence in patients with residual disease, such as CompassHER2 RD.
In a phase III trial (NSABP B-51–RTOG 1304) reported in The New England Journal of Medicine, Mamounas et al examined regional nodal irradiation for activity in preventing invasive breast cancer recurrence or death from breast cancer in patients who had negative axillary nodes after neoadjuvant...
