Human papillomavirus DNA in cervical intraepithelial neoplasia detected by in situ hybridisation.
Human papillomavirus (HPV) infection was investigated by in situ hybridisation in histological sections from 38 women with abnormal Papanicolaou smears. 13 patients had condylomatous lesions without atypia, 15 cervical intraepithelial neoplasia (CIN) I, 4 CIN II, 3 CIN III and 2 carcinoma in situ (CIS). HPV DNA was detected in 29 cases (78%) (1 specimen was technically inadequate). HPV 16 and 18, and 31, 33 and 35 were both present (67%) in CIN III. HPV 6 and 11 were more frequent in CIN I (56%) and in condylomatous lesions (38%). 31% of the condylomatous lesions without atypia contained HPV 31, 33, and 35 and 31% of those with CIN I were infected with HPV 16 and 18. These data confirm the frequent association of HPV infection with cervical cancer and CIN, and indicate that in situ hybridisation can identify patients with specific types of HPV infection at risk for cervical cancer.
