title: Sentinel lymph node biopsy versus elective neck dissection in patients with cT1-2N0 oral tongue squamous cell carcinoma.
abstract: OBJECTIVE
  This study aimed to compare the value of sentinel lymph node biopsy (SLNB) with that of elective neck dissection (END) for the prediction of cervical lymph node metastasis in patients with clinically diagnosed T1-2N0 (cT1-2N0) oral tongue squamous cell carcinoma (OTSCC), and it aimed to examine the prognostic value of individualized treatment in sentinel lymph node (SLN)-negative patients.
  
  
  METHODS
  The study entailed a retrospective review of 82 patients with cT1-2N0 OTSCC. Thirty patients underwent SLNB, and 52 patients underwent END.
  
  
  RESULTS
  There was a significant difference between the SLNB and END groups in the incidence of occult cervical lymph node metastasis in initial specimens (30% vs 11.5%; P = .037). However, there were no significant differences between the groups for 10-year overall and cervical recurrence-free survival rates and 10-year overall survival rate.
  
  
  CONCLUSIONS
  SLNB is superior to END for the prediction of cervical lymph node metastasis in patients with cT1-2N0 OTSCC. Neck dissection may be reduced for SLN-negative patients, owing to the comparable prognosis of SLNB.
