title: [The neck treatment of cN0 patients with squamous cell carcinoma of buccal mucosa].
abstract: OBJECTIVE
  The purpose of this study was to discuss the principle in neck treatment of cN0 patients with squamous cell carcinoma of buccal mucosa.
  
  
  METHODS
  101 patients of squamous cell carcinoma of buccal mucosa at the stage of cN0, who had hospitalized in West China College of Stomatology, Sichuan University from 1980 to 2000, were investigated retrospectively. All the patients received a comprehensive therapy consisting of surgical procedures combined with chemotherapy and radiotherapy. The combining radical therapy of buccal, mandible and neck was the main surgical method. Lymph nodes were cleared after operation and examined by pathological method. The patients had been followed up for more than 3 years.
  
  
  RESULTS
  17 patients had lymph nodes metastasis, the occult metastasis (OM) rate was 16.83%. It increased in the high stage of original lesion, the OM rate of T3 and T4 was 18.18% and 52.00%, respectively. The metastasized lymph nodes were mainly located in submandible and superior deep cervix lymph nodes, their respective metastasis rate was 41.18% and 29.41%.
  
  
  CONCLUSIONS
  The rate of occult metastasis of squamous cell carcinoma of buccal mucosa is high, and then we should adopt actively selective neck dissection for the cN0 patients of squamous cell carcinoma of buccal mucosa.
