Elucidating Axillary Soft Tissue Involvement in Breast Cancer: Unveiling Metastatic Mechanisms and Therapeutic Perspectives

This perspective focuses on axillary soft tissue (AXT) involvement in breast cancer, revealing diverse pathological entities beyond traditional axillary lymph node metastasis. AXT involvement is linked to increased risks of distant metastasis and locoregional failure, emphasizing its significance in predicting breast cancer outcomes. We posit that AXT involvement could signify a retrograde metastatic event stemming from reactivated circulating tumor cells navigating towards the axillary soft tissue guided by chemokines. Therefore, AXT disease warrants aggressive systemic therapy. Axillary radiation therapy could be a potentially preferable alternative to axillary lymph node dissection. Routine reporting of axillary soft tissue involvement is crucial for accurate treatment planning.
