AbstractThe Papanicolaou test generates pain and embarrassment, and cytology screening has limited sensitivity for detection of cervical neoplasia. These factors urge the use of another screening test that can overcome these limitations. We explore a completely noninvasive method using detection of human papillomavirus (HPV) DNA in women's menstrual blood (MB). The participants were divided into 3 cohorts: (i) 235 patients with cervical intraepithelial neoplasia 3 (CIN 3) (n = 48), CIN 2 (n = 60), CIN 1 (n = 58), or condyloma acuminatum (CAC) (n = 69) before treatment or remission; (ii) from the first cohort of patients, 108 CIN 3 or CIN 2 patients after treatment and 62 CIN 1 or CAC patients after remission; and (iii) 323 apparently normal subjects (ANS) without any cervical disease. The HPV genotypes of the infected patients were confirmed by direct sequencing. Quantitative real-time PCR (QRT-PCR) was used to measure the MB HPV16 load for 15 infected patients. Results showed that the sensitivity, specificity, and positive and negative predictive values for detection of MB HPV DNA in samples from patients with CIN or CAC were 82.8%, 93.1%, 90.0%, and 87.9%, respectively. Moreover, MB HPV DNA was found in samples from 22.2% of CIN 3 or CIN 2 patients after treatment, 0.0% of CIN 1 or CAC patients after remission, and 8.1% of ANS, 4 of whom were found to have CIN 1 or CAC. Furthermore, QRT-PCR showed that the normalized MB HPV16 DNA copy numbers in samples from patients with CIN 1 to CIN 3 were significantly increased. These preliminary results suggested that MB HPV DNA is a potential noninvasive marker for these premalignant cervical diseases.
