Objective: to explore the value of P16 in the predication of high-grade cervical intraepithelial (HGCIN) by P16 expression in cervical specimens.
Methods: one hundred ninety-two residual ThinPrep samples were collected and detected by HPV DNA test and P16 detected by immunocytochemistry. All women underwent colposcopy and histological examination of biopsy specimen if needed. P16 test, cytology and HR-HPV DNA (HC2) test were compared based on histological examination of colposcopic biopsies.
Results: (1) the expression of P16 showed 16.3% in normal or inflammatory cases, 46.7% in CIN 1, 93.8% in CIN 2, 91.1% in CIN 3 and 100.0% in carcinoma. A positive relation between P16 and the grade of cervical lesions was observed by Spearman analysis (P < 0.05, r = 0.900). (2) By P16 test, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for ≥ CIN 2 were 94.1%, 78.5%, 77.7%, 94.4% and 85.4% respectively. By HR-HPV DNA test, the sensitivity, specificity, PPV, NPV and accuracy for ≥ CIN 2 were 95.3%, 56.1%, 63.3%, 93.8% and 73.4% respectively. By cytological test, the sensitivity, specificity, PPV, NPV and accuracy for ≥ CIN 2 were 82.4%, 92.5%, 89.7%, 86.8% and 88.0% respectively. There were significant difference of specificity, PPV and accuracy between P16 and HR-HPV DNA (P < 0.05). And no significant difference of accuracy was found between P16 and cytology (P > 0.05).
Conclusion: the specificity, PPV and accuracy of P16 are significantly higher than those of HR-HPV DNA. Thus P16 test is valuable to diagnose HGCIN in ThinPrep specimens.

Background: Self-sampling is now a key component within HPV-based cervical screening programmes to engage individuals and enhance participation. As self-sampling is relatively new, information on the influence of pre-analytical parameters such as transit-temperature and time between sampling and testing on HPV test results requires detailed investigation.
Methods: FLOQSwabs® and Evalyn Brushes® were used to assess HPV and cellular stability over a 30-week period (0w,4w,12w,30w) at 4 °C, ambient, and 37 °C.

Objective: To assess the clinical value of DNA methylation measurement in exfoliated cervical cells for distinguishing high-grade squamous intraepithelial lesions (HSIL) from other cervical abnormalities.
Methods: A total of 276 patients were enrolled, and general clinical information was collected. Exfoliated cervical cells were obtained to assess human papillomavirus (HPV) infection, conduct ThinPrep cytology tests (TCT), and measure methylation levels of JAM3 (△CtJ) and PAX1 (△CtP).

Human papillomavirus (HPV), the predominant viral infection affecting the anogenital tract, is closely linked to the development of intraepithelial neoplasia and malignancies in the cervix and other anal regions. Currently, 15 high-risk HPVs (HR-HPVs) and 3 potential HR-HPV types have been recognized as contributors to cervical cancer. Consequently, it is imperative to conduct HR-HPV screening using suitable tests in order to identify precancerous lesions and prevent the development of cancer.

Background: Understanding the distribution of type specific human papillomavirus (HPV) genotypes in screen-detected lesions is crucial to differentiate women who are at a higher risk of developing cervical cancer. This study aimed to find out high-risk HPV genotype distribution among women of the coastal districts of Bangladesh.
Methods: This cross-sectional study conducted from January 2023 to December 2023 aimed to investigate the prevalence and distribution patterns of high-risk HPV genotypes among ever-married women aged 30-60 years residing in three coastal districts of Bangladesh.
