Purpose of the study. Evaluate the prognostic value of an independent and medical fence of the vaginal discharge for the HPV test
Abstract
The aim of the study is to assess the prognostic value of self-and medical sampling of vaginal discharge for HPV test. Materials and methods. The study included 200 women aged 18-45 years (mean age 32.7±6.9 years) who underwent traditional cytological testing and testing for HPV-stimulated stimulation. The vaginal secretion for the identification of HPV DNA by polymerase chain reaction (PCR) was performed by a woman alone using a Qvintip device and a doctor from the cervical canal. The predictive value of these techniques was evaluated according to generally accepted formulas. Results. 42% of those surveyed had HPV-stimulated stimulation. The most common types were HPV-16 (17.7%), HPV-56 (16.3%), HPV-39 (13.6%). 51.2% of HPV-positive women had a combination of several types of HPV-stimulated stimulation. The effectiveness of the examination with the Qvintip device was higher than when the doctor took the material: 38% vs 27.5% (OR=1.6, 95% CI 0.48-2.45, χ2=5.0, pχ2=0.025). The Qvintip device detected a 5-fold increase in HPV-SRV: 34.5% vs 9.5% (OR=5.0, 95% CI 1.61-6.71, χ2=15.3, pχ2=0.0001). An abnormal cytological picture was found only in HPV-positive women in 17.9% (χ2=19.9, pχ2=0.0005), of which LSIL were detected in 15.5% of cases, HSIL-2.4%. A comparative assessment of prognostic value revealed a higher sensitivity of the self-sampling method (100%) compared with the medical fence of the material (66.7%). High specificity of both methods of preparation of samples for HPV-test was revealed: 65% for independent and 72% for medical. The conclusion. The Qvintip device for self-sampling vaginal discharge for the HPV test has a high predictive value and can be recommended as an alternative method for screening cervical cancer.
