Matthew Kurian, Assistant Professor of Medicine at the University of Kentucky College of Medicine, recently shared the 2025 American Society of Clinical Oncology (ASCO) Guidelines on Sentinel Lymph Node Biopsy (SLNB) for early-stage breast cancer. These guidelines signify a significant shift towards reducing axillary surgery based on recent studies presented at the San Antonio Breast Cancer Symposium 2024.
The update suggests that routine SLNB may not be necessary for specific patients meeting certain criteria, such as postmenopausal women over 50 years with specific tumor characteristics and clinically negative axillary ultrasound results. The guidance also emphasizes the omission of Axillary Lymph Node Dissection (ALND) for select patients with positive sentinel nodes undergoing certain types of surgeries.
While these guidelines mark a progressive approach to axillary management, they raise important questions about the age criteria for skipping SLNB, the need for more diverse patient data, and the implications for different healthcare settings. The guidelines also highlight potential concerns regarding the omission of SLNB in patients undergoing Partial Breast Irradiation (PBI) and the necessity for careful patient selection and multidisciplinary discussions.
As the oncology community navigates these evolving recommendations, the focus remains on finding the delicate balance between providing effective treatment while minimizing unnecessary procedures. The guidelines underscore the importance of ongoing clinical trials to evaluate the safety and efficacy of omitting SLNB and regional nodal irradiation in low-risk patients receiving PBI.
These developments reflect the continuous efforts within the oncology field to optimize treatment strategies and improve patient outcomes. The shift towards personalized and targeted approaches underscores the commitment to delivering more precise and effective cancer care.
As research continues to advance and guidelines adapt to new findings, the oncology community remains dedicated to enhancing patient care through evidence-based practices and multidisciplinary collaborations. The 2025 ASCO Guidelines on SLNB represent a milestone in the journey towards more tailored and efficient breast cancer management.
