Abstract:
Objective To evaluate the value of human papillomavirus (HPV) 16/18 E6 protein detection in shunting and prognosis in patients with atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL). Methods A total of 98 patients with ASCUS or LSIL from the Affiliated Cancer Hospital of Shanxi Medical University between May 2014 and May 2015 were selected as the subjects. All of them received the thin-cytologic test (TCT), HPV DNA, HPV16/18 E6 protein tests and colposcopy examination. After 3-year follow-up of patients with cervical intraepithelial neoplasia (CIN) grade Ⅰor bellow lesions diagnosed by biopsy and 30 negative controls, the above tests were performed again. The efficacies of all the tests were analyzed. The value of CIN grade Ⅱ or above was predicted. Results The sensitivity, specificity, positive predictive value and negative predictive value in predicting CIN grade Ⅱor above lesions of HPV16/18 E6 protein , HPV DNA and HPV16/18 DNA was 30.8％, 95.3％, 50.0％, 90.0％, respectively; 84.6％, 37.6％, 17.2％, 94.1％, respectively and 61.5％, 67.1％, 22.2％, 91.9％, respectively in shunting study. The relative risk (RR) of CIN grade Ⅱor above lesions in patients with positive HPV16/18 E6 protein, persistent positive HPV16/18 DNA and positive HPV16/18 DNA was 13.429, 10.231 and 8.343, respectively in the follow-up study. Odds ratio (OR) of HPV16/18 E6 positive protein presenting persistent positive HPV16/18 DNA was 34.833 (95％ CI 5.020-241.711). Conclusions In patients with ASCUS and LSIL, the specificity and positive predictive value of HPV16/18 E6 protein in predicting CIN grade Ⅱ or above lesions are higher than those of HPV DNA and HPV16/18 DNA. Moreover, these patients with HPV16/18 E6 protein positive have a higher risk of developing CIN grade Ⅱ or above lesions and persistent positive HPV16/18 DNA.
