The consensus primers used were able to detect 9 types of HPVsDNAs ( HPV 6 , 11 , 16 , 18, 31 , 33,35, 42, and 583 , from which the positive cases were picked out for further identification of their genometypes of HPV-DNA by using multiple primers PCR. The results areas follows : (1)In the group of laryngeal carcinoma,the total positive rate of HPV infection was 49. 1 %(28/57) : 15. 8%(9/57)for HPV18, 12. 3%(7/57)for HPV16,5. 3 %(3/57) dual infection for HPV16 and HPV18 , 3. 5%(2/57) for mixed infection of HPV6/11 and HPV18 , and 12. 3%(7/57)for the other types. (2) In the cervical metastatic lymphnode group, 3 of the 14 cases (21. 4%) of cervical metastatic lymphnode showed positive HPV, among which there was 1 case of HPV16 infection , 1 case of HPV18 infection ,and 1 case of HPV16 and HPV18 dual infection, resulting in a rate at 7. 1% for the respective cases immediately above. (3) In the pecarcinomatous lesion group ,the positive rate of HPV infection tmixed infection of HPV6/11 and HPV18) was 11. 1 %(1/9). (4)In the vocal cord polypus group , the rate of positive reaction (HPV6/11) was 7.1% (1/14). (5) In the nomal laryngeal tissue group , 15 cases of normal laryngeal tissue adjacent to the carcinoma and 15 cases of normal laryngeal tissue opposite to the carcinoma were HPV-DNA negative.The results showed that the occurrence and development of laryngeal carcinoma were closely related to HPV infection. The distribution of genometypes of HPV varied in different lesions of larynx. The carcinogenic action of HPV in laryngeal carcinoma is also discussed in this paper.展开更多
