Inavolisib plus palbociclib/fulvestrant improved OS vs palbociclib/fulvestrant alone in PIK3CA-mutated, HR-positive, HER2-negative, advanced breast cancer.

Panelists discuss their overall perceptions of oral selective estrogen receptor degraders (SERDs) and their impact on the treatment landscape and share their experiences with elacestrant in clinical practice.

Panelists discuss potential treatment options for patients following progression on CDK4/6 inhibitors (i) in HR+/HER2– metastatic breast cancer.

Panelists discuss how in-house testing significantly reduces turnaround times by eliminating send-out delays and courier dependencies. This enables immediate sample processing, allowing for faster results delivery and prompt clinical decision-making. Health care facilities can optimize workflows through automated systems, clear communication protocols, and standardized testing procedures, minimizing bottlenecks between departments and facilitating quicker diagnosis and treatment initiation.

Panelists discuss how implementing in-house biomarker testing can significantly enhance patient care through faster turnaround times and streamlined decision-making processes. This approach reduces dependence on external laboratories while enabling more immediate clinical interventions. Key implementation considerations include staff expertise, quality control protocols, equipment costs, regulatory compliance, and testing volume to ensure operational efficiency and return on investment

The FDA has granted a breakthrough device designation to the DCISionRT test for patients with breast cancer with ductal carcinoma in situ.

Sotorasib doublet gets approved for KRAS G12C–mutated CRC, acalabrutinib triplet is cleared for previously untreated MCL, and more from OncLive.

The FDA approved datopotamab deruxtecan for select unresectable or metastatic, hormone receptor–positive, HER2-negative breast cancer.

Panelists discuss how evolving HER2 classification methods and recent trial data are reshaping treatment approaches for advanced breast cancer, particularly regarding the clinical significance of HER2-low and ultralow categories.

Panelists discuss how the latest NCCN guidelines for targeted therapies and biomarker testing in advanced/metastatic breast cancer highlight the importance of biomarker-driven approaches, with particular emphasis on the need for next-generation sequencing testing in the first-line setting, the implications of HER2-low classification, and how the recent FDA approval of a PI3K inhibitor may impact testing practices and treatment strategies.

Erica L. Mayer, MD, MPH, responses with preoperative niraparib plus dostarlimab in patients with BRCA-mutant, ER-positive, HER2-negative breast cancer.

Laura A. Huppert, MD, discusses survival outcomes of patients with metastatic breast cancer and leptomeningeal disease according to disease subtype.

Charles E. Geyer, Jr., MD, discusses the efficacy and safety of perioperative atezolizumab plus chemotherapy in stage II/III triple-negative breast cancer.

A childhood dream became a reality for Montana native Kelly K. Hunt, MD, FACS, FSSO, who has changed the face of the surgical breast oncology workforce.

Panelists discuss how adjuvant therapy in HR+/HER2- early-stage breast cancer is influenced by key risk factors, with a focus on recent studies involving CDK4/6 inhibitors like abemaciclib, ribociclib, and palbociclib, and how these treatments are shaping the adjuvant treatment strategy based on efficacy data from trials such as MonarchE, NATALEE, and PALLAS.

Drs Park and Curigliano discuss the DESTINY-Breast06 trial of T-DXd in patients with HER2-low or -ultralow, HR–positive, metastatic breast cancer.

Experts detail how recent NCCN guideline changes in dozens of tumor types are affecting their practices, and we gather all the NCCN updates in a slideshow.

Felipe Batalini, MD, and Alberto Montero, MD, MBA, CPHQ, detail how allosteric inhibitors targeting PIK3CA such as STX-478 may reduce toxicities seen with orthosteric inhibitors.

Panelists discuss how optimal biomarker testing requires careful balancing of multiple factors. Critical considerations include the turnaround time needed to inform timely treatment decisions, the comprehensiveness of testing panels to identify actionable mutations, and the demonstrated clinical utility of results for guiding therapy selection. Patient-specific factors such as cancer type, stage, prior treatments, and urgency of therapeutic decisions must guide test selection.

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.
