title: [Clinical and pathological study on cervical lymph node metastasis of supraglottic cancer].
abstract: OBJECTIVE
  To study pathological features of cervical lymph node metastasis and the relationship between supraglottic cancer and cervical lymph node metastasis.
  
  
  METHODS
  Observation of 100 whole-organ serial sections of the larynges and 170 sides of the radical neck dissection specimens.
  
  
  RESULTS
  1. Cervical lymph node metastasis 55 cases, metastatic rate 55%; 2. Four series of cervical metastasis: clinico-pathologic metastases (29 cases), pathologic metastases (26 cases), clinical metastases (5 cases), no metastasis (40 cases). 3. Four stages of metastatic lymphnode: early stage, growth stage, fullness stage and capsular perforative stage; 4. Three types of metastases: single type (21 cases), multiple type (10 cases) and aggregated (24 cases) type. 5. Metastatic rates of supraglottic cancer of different regions: aryepiglottic fold 85.7%, arytenoid cartilage area 66.6%, epiglotto-ventricular fold 56.8%, epiglottic 46.4%, ventricular fold 45.4%. 6. When the tumour spread to the perilaryngeal region, the metastatic rate was 80% to 84%.
  
  
  CONCLUSIONS
  Metastatic rate of cervical lymph node is higher in supraglottic cancers, the aggregated type and capsular perforative stage are more in metastasis lymph nodes. Analysis the original sites of supraglottic cancer is conductive to the prediction of the cervical lymph node metastasis.
