Abstract
The objective is to determine the cost-effectiveness of sentinel lymph node biopsy (SLNB) for cutaneous squamous cell carcinoma (CSCC) according to the Brigham and Women’s Hospital (BWH) Tumor Staging system. A decision analysis was utilized to examine costs and outcomes associated with the use of SLNB in patients with high-risk head and neck CSCC. Decision tree outcome probabilities were obtained from published literature. Costs were derived from Medicare reimbursement rates (US$) and effectiveness was represented by quality-adjusted life-years (QALYs). The primary outcome was the incremental cost-effectiveness ratio (ICER), with a willingness-to-pay set at $100,000 per QALY gained. SLNB was found to be a cost-effective tool for patients with T3 tumors, with an ICER of $18,110.57. Withholding SLNB was the dominant strategy for both T2a and T2b lesions, with ICERs of − $2468.99 and − $16,694.00, respectively. Withholding SLNB remained the dominant strategy when examining immunosuppressed patients with T2a or T2b lesions. In patients with head and neck CSCC, those with T3 or T2b lesions with additional risk factors not accounted for in the staging system alone, may be considered for SLNB, while in other tumor stages it may be impractical. SLNB should only be offered on an individual patient basis.
