title: [Treatment and prognosis of gingival carcinoma: a report of 116 cases].
abstract: OBJECTIVE
  The treatment and prognosis of gingival carcinoma, a common oral carcinoma, have seldom been reported. This study was to explore appropriate therapies and analyze prognostic factors of gingival carcinoma.
  
  
  METHODS
  Clinical data of 116 gingival carcinoma patients, treated at Cancer Center of Sun Yat-sen University from 1992 to 2003, were analyzed. Survival analyses were performed for patients who received surgery, radiotherapy, or surgery combined with chemotherapy or/and radiotherapy. The patients had been followed up for more than 3 years.
  
  
  RESULTS
  One hundred patients received radical therapy. The overall 3-and 5-year survival rates were 52.7% and 41.8%. The 5-year survival rates were 50.3% in surgery alone group and 49.0% in combined treatment group, without significant difference. The 5-year survival rate of radiotherapy alone group was only 20.0%. For advanced gingival carcinoma, the recurrence rate was much lower in combined treatment group than in surgery alone group. Clinical stage and surgical margin status were predictors of survival.
  
  
  CONCLUSIONS
  Surgery alone is appropriate for gingival carcinoma patients at an early stage; surgery combined with chemotherapy or/and radiotherapy is an adequate treatment for patients at advanced stages. Clinical stage and surgical margin status are important prognostic factors.
