Revolutionizing Breast Cancer Staging: Can Axillary Surgery Be Omitted in HER2-Positive Patients After Neoadjuvant Therapy?

This study offers a groundbreaking look into the potential for omitting axillary surgery in HER2-positive breast cancer patients who achieve a pathological complete response (pCR) after neoadjuvant therapy (NAT). Discover the innovative approach that could shape the future of minimally invasive breast cancer treatments and reduce patient risks.

Study Highlights:

• Key Predictors: The study shows that HER2 positivity, anti-HER2 therapy (single vs. dual blockage), and clinical responses to NAT are key indicators for predicting the possibility of avoiding axillary surgery.

• Surgery Omission: Patients with clinically node-negative (cN0) disease before NAT and complete clinical response (cCR) in the primary tumor could potentially avoid axillary staging altogether.

• Study Outcome: Early-stage patients (cT1-2N0) who respond well to NAT may not need axillary surgery, significantly lowering the risks of complications like lymphedema and pain.

Key Findings:

• No axillary involvement in patients with clinically node-negative (cN0) status before NAT.

• HER2 score and therapy type (dual blockage vs. single blockage) are major predictors for axillary pathological complete response (pCR).

• Complete clinical response (cCR) in the primary tumor strongly correlates with negative axillary nodes post-NAT.

The Road Ahead:

• The findings may mark a shift towards personalized breast cancer treatments, providing oncologists with the tools to de-escalate surgery and focus on less invasive methods, ultimately improving patient quality of life and treatment outcomes.

• Further research through multicenter studies and randomized controlled trials is essential to validate these findings.
