Abstract
OBJECTIVE: To evaluate the clinical significance of human papillomavirus (HPV) type, grade of cervical intraepithelial neoplasia (CIN) and age on the progression of CIN. STUDY DESIGN: Clinical follow-up data, histopathologic diagnosis, polymerase chain reaction (PCR) and HPV DNA typing were available on 194 patients, 119 with CIN 2/moderate dysplasia and 75 with CIN 3/severe dysplasia. RESULTS: HPV 16 was observed most frequently (47.0%) in progressed CIN, while HPV-negative cases (57.7%) were most frequently regressed. HPV positivity (P = .0466), especially HPV 16 positivity (P = .0104), was significantly more frequent than HPV negativity in the progression group. The rate of CIN progression was higher with HPV (50.5%) than without HPV (35.4%). Of the CIN cases with HPV 16, 56.5% progressed, while 30.8% of the CIN cases with HPV 6 and/or 11 and 35.4% of the CIN cases without HPV progressed. The probability of progression was 1.87-fold higher in the HPV-positive group than that in the HPV-negative group (P = .03). Multiple logistic regression analysis revealed that HPV (odds ratio 2.23, P = .0103) and grade of the lesion (odds ratio 3.30, P = .0002) in the initial biopsy strongly and independently correlated with progression of CIN. CONCLUSION: HPV status and histologic grade are independent predictive risk factors for progression and may be useful in the management of CIN.
