title: Recurrent neck disease in oral cancer.
abstract: OBJECTIVE
  The goals were to examine the clinical and pathologic features of patients who developed metastatic squamous cell carcinoma in the cervical lymph nodes after initial treatment and to identify any common patterns.
  
  
  METHODS
  A retrospective analysis of 35 patients of varying initial tumor stage was performed. There were 18 patients who had an initial neck dissection and 17 patients whose neck was managed by a "watch and wait" policy.
  
  
  RESULTS
  Recurrence frequently involved level II nodes, and extracapsular spread was invariably present. The time taken for recurrence to develop was the same in both groups of patients (15 months, P =.35), and the overall median survival time after recurrence was 18 months (12 to 25 months, 95% confidence interval). In 27 of 29 patients (93%) who had the primary tumor resected, the thickness of tumor was greater than 5 mm.
  
  
  CONCLUSIONS
  Neck recurrence may represent residual disease; it has histologically unfavorable features and consequently a poor prognosis. The frequency of recurrence at level II emphasizes the need for meticulous dissection in this region, and tumor thickness needs to be considered in planning treatment of the clinically negative neck.
