title: Expanded application of selective neck dissection with regard to nodal status.
abstract: BACKGROUND
  The efficacy of extending the application of selective neck dissection to include more-extensive neck disease in patients with squamous carcinoma of the upper aerodigestive tract remains controversial.
  
  
  METHODS
  A review of all patients undergoing selective neck dissection at a single institution during a 5-year period was undertaken. The analysis was conducted on 82 patients who received 94 selective neck dissections as part of initial therapy for management of squamous carcinoma of the upper aerodigestive tract, including: oral cavity, oropharynx, larynx, and hypopharynx.
  
  
  RESULTS
  Forty-six of the 94 dissected necks were supraomohyoid dissections, and 48 were lateral neck dissections. Sixty-five percent of patients were followed a minimum of 2 years and formed the cohort for final analysis. There were eight regional recurrences, three of which occurred in the contralateral, undissected neck. The regional recurrence rate for all patients undergoing selective neck dissection, with or without radiotherapy, according to pathologic N status was as follows: NO (1/33), 3%; N1 (1/8), 12.5%; and multiple positive nodes (3/26), 11.5%. A comparison of recurrence rates with respect to extent of neck disease (N0-N1 versus multiple positive nodes) for both types of neck dissection did not demonstrate significant differences; supraomohyoid neck dissection, p < .5; lateral neck dissection, p < .25.
  
  
  CONCLUSIONS
  There exists an expanded role for selective neck dissection in selected patients with primary squamous cell carcinoma of the upper aerodigestive tract and multiple N+ cervical disease. The selection of patients who are candidates for selective lymphadenectomy should be based on pathoanatomic considerations with reference to the primary site of tumor and demonstrated level(s) of metastatic involvement.
