Testing for high-risk human papilloma virus (HR-HPV) is an effective approach to the prevention of cervical cancer. This study in the Atsinanana area of Madagascar aimed to compare the management of women screened by visual inspection after coloration with acetic acid (VIA) and the management of women screened by HPV with VIA as a triage test.. During the last two screening campaigns, the first patients (between 28 and 120 women par center) were sampled using a dry swab, just before the acetic acid application, to test 14 genotypes of HR-HPV using Roche Diagnostics Cobas. Among the 250 screened-women, 28 (11.2%) had acidophilic lesions of the uterine cervix or suspected lesions of invasive cancer (IVA +). The HPV test was positive in 62 cases (24.8%). The HPV-based screening strategy would have reduced by 52% the number of women needing thermo-coagulation treatment: 24 women (9.6%) with primary VIA-based screening vs. 13 women (5.2%) with primary HPV-based screening; RR: 0.52 and 95%CI: 0.27-1.02. The diagnosis of severe dysplastic lesion or invasive cancer would not have changed.. Primary HPV-based screening is a strategy that could be useful for low-resource countries like Madagascar. It would reduce the rate of false positives and unnecessary treatments compared to the current strategy based on primary IVA. The questions of the feasibility and cost-benefit of this strategy should be further explored.

Colposcopes are expensive, heavy, and need specialized technical service, which may outreach the capacity of low-resource settings. Our aim was to assess the performance of smartphone-based digital images for the detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+).. Human papillomavirus (HPV)-positive women recruited through a cervical cancer screening campaign had VIA/VILI assessment (visual inspection after application of acetic acid/lugol's iodine). Cervical digital images were captured with a smartphone camera, randomly coded with no prior selection and distributed on an online database (Google Forms) for evaluation. Healthcare providers were invited to evaluate the images and identify CIN2+. The gold standard was the histopathological diagnosis. The sensitivity and specificity for the detection of CIN2+ was assessed for each reader and reported with the 95 percent confidence interval (Clopper-Pearson method).. One hundred twenty-five consecutive HPV-positive women were included, with 19 CIN2+ (15.2 percent). Forty-five gynecologists completed the assessment, one-third were considered as experts (>50 colposcopies) and two-thirds as novices (<50 colposcopies). The sensitivity and specificity for CIN 2+ detection was 71.3 percent (67.0-75.7 percent) and 62.4 percent (57.5-67.4 percent), respectively. The performance of novices and experts was similar. The readers assessed 73.1 percent of images as acceptable for diagnostic.. Smartphone-based digital images, with its high portability, have a great potential for the diagnosis of CIN2+ in low-resource context.

To assess the implementation of a cervical cancer screening strategy in rural Madagascar.. A mobile unit, equipped with a cold-coagulator, visited every six months the main health care centers in the Atsinanana area between 2013 and 2015. Cervical cancer screening was based on visual inspection with acetic acid (VIA). The lesions suggestive of intraepithelial neoplasia and limited to the cervix were coagulated on the same day. Non-eligible patients for immediate treatment were referred for appropriate investigations. We assessed the feasibility and the coverage of the screening strategy and estimated the incidence of cervical cancer in the targeted population.. One thousand five hundred and sixty-nine (18%) of 8959 women aged between 25 and 65 years old were screened. Three hundred and fifty-seven (23%) were VIA positive and 322 (21%) were eligible for immediate treatment. No serious adverse effects were observed among patients treated on the same day. Among the 35 patients not eligible for immediate treatment and referred to the hospital, 16 (46%) were lost to follow up.. When a cervical cancer screening by HPV or cytology is not possible, VIA remains a feasible and acceptable option in a disadvantaged environment. The effectiveness of this approach is still limited by the problems of access to care for patients who are not eligible for immediate treatment.

Cervical cancer (CC) is the most common cancer among sub-Saharan African women. Efficient, global reduction of CC will only be achieved by incorporation of human papillomavirus (HPV) vaccination into existing programmes. We aimed to investigate the overall and type-specific prevalences and distributions of oncogenic HPVs.. A total of 1081 women aged 30-65 years were recruited to three sequential studies in Madagascar. Demographic and historical data were obtained from participants, and specimens were self-collected for HPV testing using real-time polymerase chain reaction. HPV-positive women underwent detailed pelvic examination, visual inspection of the cervix with acetic acid, biopsy, and endocervical curettage. Data were analysed using χ(2) and t-tests, and logistic regression.. The prevalence of all 19 high-risk types of HPV was 39.3%. There were no differences in the prevalences of HPV and CC between rural and urban Malagasy women. The most common high-risk HPV types were HPV-53 (6.2%) and HPV-68 (5.8%), followed by HPV-52 (5.2%), HPV-35 (4.5%), HPV-73 (3.4%), HPV-31 (3.4%), HPV-16 (3.1%), and HPV-18 (3.1%). The prevalence of cervical intraepithelial neoplasia≥grade 2 (CIN2+) was 9.4%. CIN1-CIN3 lesions were more common in women in their 30s. The median age of participants with CIN2+ was 44 years (range 37-55). Overall, 25.8% of CIN2+ cases were associated with HPV-16/18.. This study provides evidence to support the introduction of HPV vaccination in eastern African countries such as Madagascar. Further studies are needed to screen younger women and adolescents, to provide a global vision of HPV genotype distributions and to maximize the impact of HPV vaccination.

Visual inspection of the cervix after application of 5% acetic acid (VIA) is a screening technique for cervical cancer used widely in low and middle-income countries (LMIC). To improve VIA screening performance, digital images after acid acetic application (D-VIA) are taken. The aim of this study was to evaluate the use of a smartphone for on- and off-site D-VIA diagnosis.. Women aged 30-65 years, living in the city of Ambanja, Madagascar, were recruited through a cervical cancer screening campaign. Each performed a human papillomavirus (HPV) self-sample as a primary screen. Women testing positive for HPV were referred for VIA followed by D-VIA, cervical biopsy and endocervical curettage according to routine protocol. In addition, the same day, the D-VIA was emailed to a tertiary care center for immediate assessment. Results were scored as either D-VIA normal or D-VIA abnormal, requiring immediate therapy or referral to a tertiary center. Each of the three off-site physicians were blinded to the result reported by the one on-site physician and each gave their individual assessment followed by a consensus diagnosis. Statistical analyses were conducted using STATA software.. Of the 332 women recruited, 137 (41.2%) were HPV-positive and recalled for VIA triage; compliance with this invitation was 69.3% (n = 95). Cervical intraepithelial neoplasia was detected in 17.7% and 21.7% of digital images by on-site and off-site physicians, respectively. The on-site physician had a sensitivity of 66.7% (95%CI: 30.0-90.3) and a specificity of 85.7% (95%CI: 76.7-91.6); the off-site physician consensus sensitivity was 66.7% (95%CI: 30.0-90.3) with a specificity of 82.3% (95%CI: 72.4-89.1).. This pilot study supports the use of telemedicine for off-site diagnosis of cervical intraepithelial neoplasia, with diagnostic performance similar to those achieved on-site. Further studies need to determine if smartphones can improve cervical cancer screening efficiency in LMIC.

Human papillomavirus (HPV) prevalence and type distribution were estimated among 90 female sex workers (FSWs) aged 18 to 58 years in Antananarivo, Madagascar.. A total of 90 FSWs aged 18 to 58 years in Antananarivo, Madagascar, were included in this study. Information on sexual and behavioral characteristics was obtained via a questionnaire. Exfoliated cervical cell specimens were collected for conventional cytologic examination and HPV DNA testing by polymerase chain reaction. The prevalence rates of HPV DNA and their corresponding 95% confidence intervals were stratified into the following 3 age groups: younger than 25, 25 to 34, and 35 years or older. To assess the association between HPV DNA positivity and sociodemographic and sexual behavioral factors, age-adjusted odds ratios and 95% confidence intervals were calculated using unconditional logistic regression.. The HPV prevalence in exfoliated cervical cell specimens was 36.7%. The most common HPV types found were HPV-52 (11.1%), HPV-31 and -39 (each at 5.6%), and HPV-16 and -83 (each at 3.3%). The prevalence of low-grade squamous intraepithelial lesions was 3.3%, and that of atypical squamous cells of undetermined significance was 18.9%. No high-grade lesion was found. Although associations were imprecise, the HPV prevalence was higher among women who reported younger age at the first intercourse, contraceptive use, a history of cervical lesions, and no history of condom use.. The prevalence rates of HPV and cervical lesions among FSWs in Madagascar appear higher than among FSW populations from other African countries with a relatively higher population-based prevalence of human immunodeficiency virus infection.
