Sentinel Lymph Node Biopsy in Clinically Node‐Negative Merkel Cell Carcinoma: An Update of the Westmead Hospital Experience

Key Points

• To assess the efficacy of sentinel lymph node biopsy (SLNB) in patients with clinically node-negative Merkel cell carcinoma (MCC).
• Analyzed data from patients with clinically node-negative MCC
• Evaluated SLNB positivity rates
• Assessed false-negative rates under close surveillance
• SLNB positivity rate of nearly 40%
• Supports improved staging accuracy in MCC management
• Demonstrates acceptable false-negative rates
