HER2-low and HER2-ultra-low salivary gland carcinomas: an exploratory study

Puntos clave

• Salivary gland carcinomas exhibit varying HER2 expression levels, influencing classification.
• Specifically, both HER2-low and HER2-ultra-low cases present unique characteristics essential for treatment strategies.
• Observational analysis focused on biomarkers related to HER2 expression in diverse carcinoma subtypes.
• Highlights the need for further investigation into HER2-targeted therapies in these rare cancers.
