The clinical role of human papilloma virus typing.
Patients with abnormal Pap smears underwent repeat Pap smear, colposcopy, biopsy, and human papilloma virus (HPV) typing to identify the presence of CIN and to assess the correlation of HPV type to grade of CIN and behavior of CIN. A total of 334 patients underwent evaluation and typing with Southern blot methodology. Fifty-five percent (185) of the patients demonstrated HPV viral sequences; 98 of the 185 positive patients demonstrated HPV types 16, 18. The presence of HPV sequences was not associated with a higher frequency of positive cytology of CIN II or III. High-grade CIN (II or III) was seen in 17.3, 13.5, 13.8, and 10.7% of patients with HPV 16, 18; 6, 11; 31, 33, 35; or no HPV sequences. Of 52 patients with normal cytology and biopsy revealing less than or equal to CIN I, no patients with types 6, 11, 3/5 patients with 31, 33, 35, 3/15 patients with 16, 18, and 2/23 patients with no HPV sequences progressed to greater than or equal to CIN II. These data do not support a role for HPV typing in predicting the initial histology. Typing may be of some value in monitoring patients with low-grade lesions.
