Multi-omics analysis reveals the prognostic value and immunomodulatory role of CTSW in breast cancer

This study underscores the pivotal role of CTSW in breast cancer immunology, positioning it as a key indicator of a potent anti-tumor immune response within the TME. Collectively, our findings establish a robust, data-driven hypothesis that CTSW's high expression, particularly in TNBC, reflects a favorable, functionally active immune state. This comprehensive in silico investigation substantiates CTSW's potential as a prognostic biomarker and provides a strong rationale for its future experimental validation as a therapeutic target.
