title: [Surgical treatment of cervical lymph nodes in 301 patients with oral squamous cell carcinoma].
abstract: OBJECTIVE
  To evaluate cervical lymph metastases and its surgical treatment of oral carcinoma with regard to primary location and TNM classification.
  
  
  METHODS
  301 previously untreated patients were included in the follow-up study to calculate the rate of histopathologically positive lymph metastasis and the rate of recurrences in untreated necks and after FND (functional neck dissection).
  
  
  RESULTS
  Lymph node pathologic positive rates were N0 7.4%, N1 14.7%, N2 76.2%. Recurrences occurred in 32.1% untreated necks and 14.7% necks after FND of carcinomas of tongue, buccal, lower-gingiva and oral floor, while rarely in necks of carcinomas of palate and upper-gingiva.
  
  
  CONCLUSIONS
  TNM classification is useful to estimate lymph metastasis. Application of elective neck dissection needs to expand in carcinomas of the above four sites. It should be careful when choose FND.
