Cost-utility of sentinel lymph node biopsy in cT1-T2N0 oral cancer

SLNB is a good diagnostic strategy to evaluate cT1-T2N0 oral cancer. SLNB is the preferred strategy in a 5- or 10-year time horizon. From a lifetime horizon, END may be preferred. SLNB may become the optimal strategy from all time horizons if its sensitivity can be slightly improved.
