To Look or Not to Look? Axillary Imaging: Less May Be More.

Area of Science:

• Oncology
• Radiology
• Surgical Oncology

Background:

• Axillary lymph node status is critical for breast cancer prognosis and treatment planning.
• Imaging, including ultrasound (US), aids axillary assessment but requires careful clinical consideration.
• Multidisciplinary communication is vital for appropriate axillary imaging decisions.

Purpose of the Study:

• To review axillary imaging strategies in breast cancer patients.
• To identify clinical scenarios where axillary US and/or image-guided biopsy may not be indicated.
• Focus on newly diagnosed patients meeting Z0011 criteria and those undergoing neoadjuvant chemotherapy.

Main Methods:

• Review of clinical guidelines and relevant literature.
• Analysis of decision-making processes for axillary imaging in specific breast cancer patient groups.
• Focus on indications and contraindications for axillary ultrasound and biopsy.

Main Results:

• Axillary US and biopsy are not always necessary, especially in early-stage breast cancer meeting specific criteria (e.g., Z0011).
• In patients undergoing neoadjuvant chemotherapy, the role and timing of axillary imaging require careful evaluation.
• Clinical appropriateness and multidisciplinary input are paramount.

Conclusions:

• Judicious use of axillary imaging in breast cancer is essential.
• Avoidance of unnecessary axillary US and biopsy can streamline patient care.
• Tailoring imaging decisions to clinical context and patient characteristics is key.
