PURPOSE Adjunct cervical cancer screening methods are under evaluation to improve the diagnostic accuracy of human papillomavirus (HPV)-based screening in low- and middle-income countries. We evaluated the feasibility and acceptability of smartphone-based cervicography among HPV-positive women living with HIV (WLWH) in Western Kenya. METHODS HPV-positive WLWH of 25-49 years of age enrolled in a clinical trial (ClinicalTrials.gov identifier: NCT04191967 ) had digital images of the cervix taken using a smartphone by a nonphysician provider following visual inspection with acetic acid. All participants had colposcopy-directed biopsy before treatment. Cervical images were evaluated by three off-site colposcopists for quality, diagnostic utility, and assigned a presumed diagnosis. We determined the proportion of images rates as low, medium, or high quality, interobserver agreement using Cohen’s Kappa statistic, and the off-site colposcopist’s sensitivity and specificity for diagnosis of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) compared with histopathology. Acceptability was evaluated using a questionnaire. RESULTS One hundred sixty-four HPV-positive WLWH underwent cervicography during the study period. Mean age was 37.3 years. Images from the first 94 participants were evaluated by off-site colposcopists, with a majority (70.9%) rated as high quality. Off-site colposcopists had a sensitivity ranging from 21.4% (95% CI, 0.06 to 0.43) to 35.7% (95% CI, 0.26 to 0.46) and a specificity between 85.5% (95% CI, 0.81 to 0.90) to 94.9% (95% CI, 0.92 to 0.98) for diagnosis of CIN2+ based compared with histopathology. The majority of women, 99.4%, were comfortable having an image of their cervix taken as part of screening. CONCLUSION Cervicography by a nonphysician provider as an adjunct to HPV-based screening among WLWH in a low- and middle-income country setting is feasible and acceptable. However, low sensitivity for diagnosis of CIN2+ by off-site expert colposcopists highlights the limitations of cervicography.
Although cervical cancer is preventable, in 2018, approximately 570,000 new cases occurred globally. Cervical cancer disproportionately affects low-and middle-income countries (LMICs), which accounted for 90% of deaths in 2018. Women living with the Human Immunodeficiency Virus (WLWH) are at increased risk of cervical cancer and are in urgent need of prevention. Despite evidence-based guidelines for screening and prevention of cervical cancer, the majority of WLWH in LMICs lack access to cervical cancer screening. Despite tremendous gains made in access to life prolonging antiretroviral therapy for WLWH, most are served by vertical human immunodeficiency virus (HIV) programmes which do not integrate these two crucial services. We present a case of a WLWH, in HIV care for a decade, who was recently diagnosed with preventable, advanced stage cervical cancer.
