In this insightful video and accompanying slides, pathologist Prof. Frédérique Penault-Llorca and medical oncologist Dr Aditya Bardia explore the evolving landscape of biomarker testing in HR+/HER2- metastatic breast cancer.

 

The experts discuss when and how to effectively utilise liquid and tumour biopsies, the importance of including all relevant biomarkers in test requests throughout the patient journey, and how these test results directly impact treatment decisions and patient management.

 

This discussion offers valuable guidance for optimising personalised care in advanced breast cancer. Watch the video above and download the accompanying slides for more details.

 

Clinical takeaways

  • Liquid biopsies offer a less invasive alternative to traditional tissue biopsies in patients with advanced breast cancer to examine molecular features 
  • The role of liquid biopsy should be seen as a complementary testing method to tissue-based assays, and the information derived should be reviewed in combination with tissue results 
  • Liquid biopsy can detect mutations such as ESR1 and PIK3CA that are often associated with resistance to endocrine therapies and may be therapeutic targets
  • Multigene NGS testing is recommended by the ESMO and NCCN guidelines to ensure a broad spectrum of genetic alterations can be detected 
  1. Know the testing landscape in HR+/HER2- metastatic breast cancer, when and how to test using liquid and tumour biopsies 
  2. Be able to include all relevant biomarkers in test requests across the breast cancer  
    patient journey
  3. Understand the implications of biomarker testing results on the management of HR+/HER2- metastatic breast cancer patients 

Frédérique PENAULT-LLORCA, MD, PhD, graduated as a medical specialist in pathology in 1993 and in oncology in 1995. Also, in 1995, she received a PhD from the Université d’Aix-Marseille II in cellular biology and microbiology, on the topic of HER2. Frédérique PENAULT-LLORCA is currently professor of pathology at the University of Clermont-Ferrand, CEO of the Comprehensive Regional Cancer Institute Centre Jean PERRIN, Clermont-Ferrand, France, deputy director of the research team INSERM 1240 IMoST, and head of the Molecular Biology Plateform at Centre Jean Perrin. She serves as vice-president of the UNICANCER group and chairs of the Immuno-Oncology group at UNICANCER R&D. She is a member of several pathology and oncology societies, with her main areas of expertise being female cancers. She co-chairs the French breast cancer guidelines of Nice-St Paul. Frédérique PENAULT-LLORCA has conducted various biomarkers-based research studies in breast, lung, digestive tract, prostate and thyroid cancer in relation to response to targeted therapies and immunotherapies. Frédérique PENAULT-LLORCA has participated to more than 469 peer-reviewed publications and several books on female cancers and pathologic testing methods and issues.

Dr. Bardia is an internationally renowned breast oncologist known for his pioneering clinical and translational research in the field of cancer therapeutics, particularly antibody drug conjugates. Dr. Bardia led the development of sacituzumab govitecan, the first ADC approved for patients with metastatic triple negative breast cancer, as well as other including trastuzumab deruxtecan and datapotamab deruxtecan. Dr. Bardia also led the clinical development of elacestrant, the first oral SERD approved for patients with metastatic HR+ positive breast cancer. In translational collaboration with various labs, identified role of ESR1 mutations in mediating endocrine resistance, RB1 mutations in mediating CDK 4/6i resistance and TOP1 mutations in mediating ADC resistance. Besides cutting-edge research, Dr. Bardia is highly regarded among peers as an excellent mentor and strong advocate for academic trainees and junior faculty members. Dr. Bardia has received several awards including outstanding award for research excellence at Mayo Clinic, Young Investigator Award from ASCO, Distinguished researcher award from MASCO, and Douglas Family Foundation prize for excellence in oncology research.
