The concept of the sentinel lymph node biopsy (SLNB) has been universally accepted for melanoma, however, remains controversial for squamous cell carcinoma (SCC). We performed a quantitative review on 260 cases of SCC that had a SLNB. The positivity rate was found to be 14.6%. Literature was qualitatively reviewed to determine whether a positive SLNB has any bearing on prognosis in SCC cases, finding a significant relationship between poor prognosis and a positive SLN (P = 0.0082).
