Objectives: To compare the sensitivity, specificity, positive and negative predictive values, and accuracy of Papanicolaou test with visual inspection with acetic acid (VIA)/VIA using magnification devices (VIAM) and develop the best strategy for screening in low resource settings.
Materials And Methods: This is a prospective cross-sectional study on 408 symptomatic multiparous women in the reproductive age group, sequentially using the Papanicolaou test, the VIA, and the VIAM for screening. Women with a positive screening test underwent guided biopsy and endocervical curettage. The site of biopsy was recorded. Histopathological findings were taken as the "gold" standard in comparing the methods.
Results: The mean (SD) age was 32.3 (6.8) years (range, 15-49 years), whereas the mean (SD) parity was 2.9 (1.2) (range, 1-9). Abnormal cytological findings were detected in 2.9% patients, whereas the remaining smears were negative for any intraepithelial lesion or malignancy. A total of 113 cases were screened positive by one/all methods. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the Papanicolaou test, the VIA, and the VIAM were 24, 98, 42, 96, and 94%; 95, 78, 19, 99, and 79%; and 95, 78, 19, 99, and 79%, respectively, for high-grade lesions.
Conclusions: The Papanicolaou test had low sensitivity but high specificity, whereas visual detection methods had a high sensitivity in addition to being cheaper. Alternative methods of screening such as VIA/VIAM can be a valuable alternative to the Papanicolaou test for cervical cancer screening in low resource settings. Visual inspection using magnification devices may be of benefit over VIA in doubtful cases.

Background: Cervical cancer is the most common gynaecological cancer worldwide, causing morbidity and mortality, especially in developing countries like Nigeria. It develops from premalignant lesions of the cervix. Human immune deficiency virus (HIV) increases the risk of dysplastic changes in the cervix.

In cervical cancer screening, cytology is used as a triage test to refer high-risk human papillomavirus (HR-HPV)-positive women for colposcopy, but its accuracy is inadequate. The present study aimed to demonstrate that the presence of atypical cells with large vacuoles in the cytoplasm of parabasal cells, referred to as vacuolated parabasal cells (VPCs), which are observed in the Pap smears of HPV-positive women, is associated with specific HPV genotypes. Among 2175 patients, 310 with a single HR-HPV infection and cytological diagnosis of high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells not excluding HSIL (ASC-H) were included, of which 86 were infected with HPV16.

Background: Female recipients of allogeneic hematopoietic stem cell transplantation are at high risk of developing human papillomavirus (HPV)-associated lesions and (pre)cancer. We describe the results of a cervical cancer screening program in these women.
Methods: From 2010 to 2022, 70 female recipients of allogeneic hematopoietic stem cell transplantation in our institution entered a standardized protocol of gynecological evaluation.

Background: Pap smear screenings effectively reduce the incidence of cervical cancer. However, the effectiveness of practical teaching strategies for this procedure is seldom discussed.
Purpose: This study was designed to evaluate the effectiveness of a Pap smear screening training approach using the two strategies of classroom simulation and practical community screening demonstrations.

Background: Cervical cytology screening and colposcopy play crucial roles in cervical intraepithelial neoplasia (CIN) and cervical cancer prevention. Previous studies have provided evidence that artificial intelligence (AI) has remarkable diagnostic accuracy in these procedures. With this systematic review and meta-analysis, we aimed to examine the pooled accuracy, sensitivity, and specificity of AI-assisted cervical cytology screening and colposcopy for cervical intraepithelial neoplasia and cervical cancer screening.
