title: [Detection of human papillomavirus in laryngeal carcinoma with digoxigenin labelled probe prepared by polymerase chain reaction].
abstract: OBJECTIVE
  To study the relationship between laryngeal carcinoma and human papillomavirus (HPV), and describe distribution, expression of genome types of HPV in laryngeal carcinoma.
  
  
  METHODS
  We used a non-radioactive digoxigenin labeled probe prepared by polymerase chain reaction (PCR) to test the fresh tissue samples from 146 cases with different laryngeal lesions. The labelled probe of HPV consensus primers was obtained, which enabled detection of nine types of HPV DNAs that were HPV 6, 11, 16, 18, 31, 33, 35, 42 and 58. The genome types of HPV DNA positive cases were determined by using multiple primers PCR.
  
  
  RESULTS
  The results turned out to be as follows: The HPV infection positive rate was 45.6%(31/68) for laryngeal carcinoma, 20.0% (3/15) for neck metastatic lymphnode, 11.8%(2/17) for precarcinomatous lesions and 6.3%(1/16) for vocal cord polypus. 15 cases of normal tissues adjacent to carcinoma and another 15 normal tissues opposite to the carcinoma were all HPV DNA negative. HPV16, 18 types are the main types of laryngeal carcinoma and HPV6, 11 types often appear in benign lesions of larynx.
  
  
  CONCLUSIONS
  These results implicated that the occurrence and development of laryngeal carcinoma may be closely related to HPV infection.
