title: [Study of RB gene in carcinoma of larynx].
abstract: OBJECTIVE
  To probe the mutations of RB gene in laryngeal carcinoma, and the relation between it and the clinical phase.
  
  
  METHODS
  The mutations were detected by PCR-SSCP (polymerase chain reaction-single strand conformation polymorphism).
  
  
  RESULTS
  In laryngeal carcinoma, the mutations were identified in 14(15.5%) of 90 samples, of which 2 were large deletion, 12 were abnormal in electrophoresis of SSCP. The mutations of I-II stage tumor were 5(13.9%), of III-IV were 9(16.7%), there wasn't a significant difference between them.
  
  
  CONCLUSIONS
  RB gene mutation takes part in the development of laryngeal carcinoma. But there wasn't relation between RB gene mutation and the course of laryngeal carcinoma.
