title: Analysis of curative effects on laryngeal carcinoma patients in the northeast region of China.
abstract: CONCLUSIONS
  In the past 20 years, the level of laryngeal carcinoma treatment in our country has been significantly improved. Early diagnosis is the key for increasing the ratio of larynx preservation surgeries and improving survival rates. The main causes of death within 5 years are local recurrence and metastasis.
  
  
  OBJECTIVE
  To describe the main treatment methods for laryngeal carcinoma in China in the 1980s and 1990s and their prospective effects and investigate the prognostic factors.
  
  
  METHODS
  A retrospective investigation was performed on the 1115 laryngeal carcinoma patients receiving treatment in the department of ENT of the First Affiliated Hospital of China Medical University during 1983-1996 and the survival rates and causes of death were analyzed statistically.
  
  
  RESULTS
  There were 780 patients surviving for more than 5 years, 260 dead patients, and 75 patients lost to follow-up. According to the cumulative survival rate curve, the 5-year survival rate was 77% (94% for stage I, 89% for stage II, 82% for stage III, and 66% for stage IV). Glottic cancer has the highest 5-year survival rate, followed by supraglottic cancer, subglottic cancer, and transglottic cancer. The 5-year survival rate of patients receiving partial laryngectomy was 85%, while the 5-year survival rate of those receiving total laryngectomy was 68%. The leading causes of death within 5 years were local recurrence and metastasis (70%), and the causes of death were unknown in 14% of cases.
