OBJECTIVE
The aim of this study was to evaluate high-risk (HR) HPV DNA test to predict recurrence/residual disease in patients treated for CIN (cervical intraepithelial neoplasia). METHODS: Four hundred and fifty-two patients treated with LLETZ (large loop excision of the transformation zone) were followed by HR HPV DNA test, cytology and colposcopy. The sensitivity, specificity and diagnostic odds ratios in predicting recurrence/residual disease were compared to those of cytology and HPV DNA test. RESULTS: Fourteen patients (3.1 %) developed recurrent/residual disease, during follow up. Of these women, 7 were diagnosed at the time of recurrence with a CIN 1 lesion, 5 with a CIN 2 lesion, and 2 with a CIN 3 lesion. The sensitivity and specificity of the HPV DNA test were 92.9% (CI 68.5%, 98.7%) and 75.3% (71.1%, 79.1%). The sensitivity and specificity of the cytology were 71.4% (45.4%, 88.3%) and 92.5% (89.6%, 94.6%), respectively. The likelihood ratio of a positive and negative HPV DNA test were 3.77 (3.03, 4.69) and 0.09 (0.01, 0.63). And the likelihood ratio of a positive and negative cytology were 9.48 (5.95, 15.11) and 0.31 (0.13, 0.71). The accuracy of cytology and HPV DNA test were 94.7% and 78.3%. The sensitivity and specificity of the combination test (PAP and/or HPV DNA test) were 92.9% (68.5%, 98.7%) and 73.1% (68.7%, 77.0%). The likelihood ratio of a positive and negative combination test were 3.45 (2.79, 4.26) and 0.10 (0.01, 0.65). CONCLUSION: Cytology remains the base in the follow up after of CIN. HPV DNA test increase the sensitivity of cytology. Negative HPV test can rule out recurrent/residual disease. |
