BackgroundSub-Saharan African countries are marked by a high incidence of cervical cancer. Madagascar ranks 11th among the countries with the highest cervical cancer incidence worldwide. ObjectiveThe aim of the study was to evaluate the performances of digital smartphone-based visual inspection with acetic acid (D-VIA) and Lugol’s iodine (D-VILI) for diagnosing cervical precancer and cancer. MethodsHuman papillomavirus (HPV)-positive women recruited through a cervical screening campaign had D-VIA and D-VILI examinations with endocervical curettage (ECC) and cervical biopsy. Three images were captured for each woman (native, D-VIA, D-VILI) using a smartphone camera. The images were randomly coded and distributed on 2 online databases (Google Forms). The D-VIA form included native and D-VIA images, and the D-VILI form included native and D-VILI images. Pathological cases were defined as cervical intraepithelial neoplasia grade 2 or worse (CIN2+). Physicians rated the images as non-pathological or pathological. Using the ECC and cervical biopsy results as references, the sensitivity and specificity of D-VIA and D-VILI examinations for each and all physicians were calculated. ResultsAltogether, 15 clinicians assessed 240 images. Sensitivity was higher for the D-VIA interpretations (94.1%; 95% CI 81.6-98.3) than for the D-VILI interpretations (78.8%; 95% CI 54.1-92.1; P=.009). In contrast, the specificity was higher for the D-VILI interpretations (56.4%; 95% CI 38.3-72.9) than for the D-VIA interpretations (50.4%; 95% CI 35.9-64.8; P=.005). ConclusionSmartphone-based image for triage of HPV-positive women is more accurate for detecting CIN2+ lesions with D-VIA than D-VILI, although with a small loss of specificity.

The WHO recommends the use of human papillomavirus (HPV) testing for primary cervical cancer (CC) screening because of its high sensitivity. However, triage is desirable to correctly identify HPV+ women who have high‐grade lesions (CIN2+) and require treatment. The ANRS‐12375 study was conducted in Côte d'Ivoire, Burkina Faso and Cambodia to assess the performance, feasibility and benefits of different triage options for detecting CIN2+ lesions: partial (HPV16 and HPV16/18/45) and extended genotyping, visual inspection (VIA) alone and VIA combined with partial genotyping. VIA was performed by gynecologists. The sensitivity, specificity, and diagnostic likelihood ratio (DLR) of each triage option for detecting CIN2+ lesions with histology as a reference standard were calculated. Of the 2253 women living with HIV (WLHIV) included, 932 (41%) were HPV+. A CIN2+ lesion was identified in 105 (13%) of the 777 participants with histopathology results. The sensitivity of VIA as a triage test for CIN2+ patients was 89%, while that for extended genotyping was 89%, that for HPV16/18/45 partial genotyping was 51%, and that for HPV16 partial genotyping was 36%. The specificities for these tests were 45%, 29%, 72%., and 85%, respectively. Combining VIA and/or partial genotyping positivity slightly increased the sensitivity (94%) at the cost of lower specificity (28%). There was significant intersite heterogeneity (p =.04). Among the three triage tests with a sensitivity ≥85%, the VIA had the highest specificity and positive likelihood ratio (p <.001). VIA and extended genotyping, whether independent or combined, are good triage options with high sensitivity for identifying WLHIV needing treatment for CIN2+. [ABSTRACT FROM AUTHOR]

Objective: To assess the impact of thermal ablation (TA) for the treatment of cervical dysplasia on fertility and pregnancy outcomes among women screened for cervical cancer in Cameroon. Design: Retrospective cohort study. Setting: Dschang health district, Cameroon. Population: Participants aged 30–45 years from two screening trials conducted between 2015 and 2020 in Dschang District Hospital. Methods: Participants were primarily screened for human papillomavirus infection, triaged by visual inspection and treated by TA if needed. Between October 2021 and March 2022, interviews on subsequent fertility were conducted with participants treated by TA and a control group of untreated women. Main Outcome Measures: Pregnancy and miscarriage after screening/treatment. Results: A total of 760 participants (219 treated and 541 untreated) completed the survey, with a mean follow‐up time of 1297 days. Sixty‐two women (28.3%) treated by TA reported a pregnancy postscreening versus 165 (30.5%) in the control group (p = 0.550). Adjusted for potential confounders, the hazard ratio of pregnancy for treated compared with untreated women was 0.82 (0.54–1.24, p = 0.350). Among women reporting pregnancies with a known outcome and which were not voluntarily terminated, 18 (35.3%) treated participants had a miscarriage versus 31 (21.4%) in the control group (p = 0.048). In the adjusted model, no association remained between TA and miscarriage (1.04, 0.39–2.78, p = 0.935). Conclusions: In our study population, TA did not significantly impact fertility nor miscarriage risk. Our results support the widespread use of TA as a treatment of choice for precancerous cervical lesions in low‐income settings. [ABSTRACT FROM AUTHOR]

Background: Screening participation at recommended intervals is a crucial component of cervical cancer prevention effectiveness. However, little is known regarding the rate of re-screening in a Sub-Saharan context. This study aimed to estimate the re-screening rate of women in a semi-rural after an initial HPV-based screening and identify factors that influence adherence. Methods: This cohort study at the Annex Regional Hospital of Dschang enrolled women screened for cervical cancer over 5 years ago and due for re-screening. Women who initially tested HPV-positive (n = 132) and a random sample of HPV-negative women (n = 220) participated in a telephone survey between October 2021 and March 2022 to assess re-screening participation and reasons. Sociodemographic factors were collected, and associations with rescreening were evaluated. Results: A total of 352 participants aged under 50 years (mean age 37.4 years) were contacted, and 203 (58.0%) completed the survey. The proportion of women who complied with the screening recommendation was 34.0% (95% CI 27.5% − 40.5%), The weighted re-screening proportion was 28.4%. Age, marital status, education level, type of employment, and place of residence were not associated with the rate of re-screening. Main reported barriers to re-screening were lack of information (39.0%), forgetfulness (39.0%), and impression of being in good health (30.0%). Women who remembered the recommended screening interval were 2 to 3 times more likely to undergo re-screening (aOR (adjusted odds ratio) = 2.3 [1.2–4.4], p = 0.013). Human papilloma virus- positive status at the initial screening was also associated with the re-screening((aOR) (95% CI): 3.4 (1.8–6.5). Conclusion: Following an initial Human Papilloma Virus-based screening campaign in the West Region of Cameroon, one third of women adhered to re-screening within the recommended timeframe. Existing screening strategies would benefit from developing better information approaches to reinforce the importance of repeated cervical cancer screening. [ABSTRACT FROM AUTHOR]
