High SLNB failure rates have also been observed in HN melanoma and squamous cell carcinoma and been largely attributed to anatomic complexity.15<\/sup>-17<\/sup><\/p>\n

In this large cohort study of patients with clinically node-negative HN MCC who underwent SLNB, we sought to evaluate SLNB accuracy within this anatomically complex region and to identify factors associated with SLNB failure and nodal disease. Our goal was to inform staging practices and refine risk stratification strategies to improve treatment planning and outcomes for this high-risk population.<\/p>\n","protected":false},"excerpt":{"rendered":"
