Sentinel node biopsy in early oral squamous cell carcinomas: Long-term follow-up and nodal failure analysis

SNB is a reliable staging tool for T1/T2 cN0 OSCC, without adverse effect on patient survival and fewer complications. No late recurrences occurred in long-term follow-up. Close follow-up is mandatory for SN+ patients, who are at higher risk of nodal recurrence and have worse prognosis.
