“…In contrast, SLNB may play a significant role in the management of SCC. An association of positive SNL and poor prognosis of cutaneous SCC has been previously demonstrated in several studies, showing a 96% 5-year survival with no regional lymph node involvement [ 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 ]. The 5-year survival decreases to 72% with adequate treatment, and 25–35% with no treatment [ 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 ].…”
