COR2ED - Oncology Medical Conversation

Pre-analytical Phase Challenges and Biomarker Testing in HER2+ Metastatic Breast Cancer 

 

Key clinical takeaways:  

Metastatic breast cancer (mBC) is a complex, heterogeneous disease requiring multidisciplinary collaboration. Pathologists are central to this process to ensure accurate interpretation and optimal patient management   

Incorporating HER2-low and HER2-ultralow categories in biomarker testing is critical for mBC due to the demonstrated efficacy of HER2-targeted antibody-drug conjugates, such as trastuzumab deruxtecan, in these patient subsets, expanding therapeutic options beyond traditional HER2-positive cases   

High-quality pre-analytical handling and nuanced interpretation are essential for accurate HER2 classification, particularly for HER2-low and –ultralow disease. Small errors in testing or interpretation can lead to missed treatment opportunities.

Understanding HER2-low and HER2-ultralow classification in mBC

In this video podcast moderated by the Oncology Brothers, Dr Komal Jhaveri provides a practical overview of how this shift beyond a binary HER2 model translates into everyday clinical practice.

The experts explore:

Key efficacy data from DESTINY-Breast04 and DESTINY-Breast06, and their impact on the HER2 treatment framework

The clinical relevance of HER2-low and HER2-ultralow categories, and review the CAP reporting template

When and why to perform re-biopsy to detect changes in HER2 expression over time

Best practices for monitoring and managing T-DXd–related adverse events, including nausea, vomiting, fatigue and ILD/pneumonitis

 

Watch now to deepen your understanding of HER2-low and HER2-ultralow classification, refine how and when you test, and appreciate the impact on therapeutic decision-making in mBC.

 

Clinical takeaways

 

DESTINY-Breast04 and DESTINY-Breast-06 established T-DXd as an effective option for HER2-low and HER2-ultralow mBC, improving PFS and OS and showing that even minimal HER2 expression can identify patients who benefit from T-DXd

Current CAP reporting template separates HER2-low (IHC 1+ or 2+/ISH–) and HER2-ultralow (IHC 0 with faint or incomplete membrane staining in ≤10% of tumour cells) from true HER2-0, creating treatment-defining strata for HER2-targeted ADCs such as T-DXd

Because HER2 expression is dynamic between primary and metastatic sites and over time, re-biopsy at progression, particularly in tumours previously scored as HER2-0, should be considered to identify new candidates for T-DXd

T-DXd delivers substantial antitumour activity, but treatment-related adverse events, including nausea, vomiting, fatigue, alopecia and, in particular, ILD/pneumonitis, require careful and proactive management. Clinicians should apply structured supportive care and early, vigilant monitoring to ensure safe and sustained treatment

In this podcast, Medical Oncologist, Dr Aman Chauhan and Neuroendocrine Patient Advocate, Susan Meckler-Plummer, discuss extrapulmonary high-grade neuroendocrine carcinomas (EP-NECs), a rare, aggressive, and often misunderstood subset of neuroendocrine cancers.  

They clarify the crucial differences between NETs and NECs, explain why accurate classification and rapid treatment are essential, and highlight current and emerging therapeutic approaches, including DLL3-targeted therapies.  

Through both HCP and patient-centred perspectives, the conversation addresses real-world challenges, the importance of support networks, and the growing sense of hope for people affected by this difficult disease. 

Key clinical takeaways:  

Unlike NETs, EP-NECs are poorly differentiated, high-grade, aggressive, and fast-growing cancers, with a need for more effective treatments

While there remains a medical need for effective treatment of EP-NECs, clinical studies with DLL3-targeted agents show promise 

Accessing a support network can provide emotional reinforcement and information for patients and their care partners

How are advances in radioligand therapy shaping the treatment of neuroendocrine tumours, and what does recent trial evidence tell us? What are the key considerations for patient selection, sequencing, and safety? 

In this podcast moderated by the Oncology Brothers, Drs Rohit and Rahul Gosain are joined by medical oncologist Dr Heloisa Soares and nuclear medicine physician Prof. Ken Herrmann to explore the evolving role of targeted radioligand therapy in NETs. 

As the conversation unfolds, the experts discuss evidence from recent studies, including the COMPETE trial, share practical insights on multidisciplinary decision-making, and highlight future directions such as the potential for first-line treatment with radioligand therapy. 

Key clinical takeaways:  

Pair the right patient with the right treatment using an understanding of the key clinical studies 

The role of PRRT as a very effective 2nd-line treatment was consolidated by the COMPETE study data  

The best outcomes are achieved through multi-disciplinary collaborations that include the patient
