简要总结
The purpose of this study is to determine whether smartphone photos may assist health-care worker (on-site) and to evaluate the diagnostic reliability and accuracy of cervical examination with smartphone photos of VIA (D-VIA), on-site and off-site, compared with conventional VIA, for human papillomavirus (HPV) positive women.
详细描述
Background: Cervical cancer is the leading cause of cancer death in females in Madagascar. In this country, a large-scale screening of precancerous lesions with cytology is hardly possible, because of the lack of specialists and infrastructures. Visual inspection of the cervix with application of 5% acetic acid (VIA) is an inexpensive alternative but very subjective since it depends on the examiner's experience. Mobile telemedicine is a very promising tool in order to assist non-expert health-care workers in rural area for cervical cancer screening.
Objective
To assess if Smartphone may assist health-care worker (on-site) and to evaluate the diagnostic reliability and accuracy of cervical examination with smartphone photos of VIA (D-VIA) compared with conventional VIA, for women testing positive for human papillomavirus (HPV).
Material and method: On-site health care workers will be trained in VIA. Prescreened HPV-positive women will be referred to VIA evaluation, during which digital images with a smartphone (D-VIA) will be taken for later evaluation by a VIA specialist in Geneva linked by telemedicine. Women with positive VIA results will be treated with cold coagulation if eligible. Histological results will be considered as gold standard. The results will be analyzed with Cohen's kappa coefficient, Mcnemar's test and Bonferroni's adjustment for multiple comparisons to assess the performance of D-VIA.
Expected results: Based on the results of this project, the investigators will develop an educational training and quality assurance program for health providers for VIA and so contribute to a scaling-up of cervical cancer control. An appropriate triage by VIA will reduce not only an excessive referral rate but also an excessive treatment delay, giving the possibility of a "screen (HPV), see (VIA/D-VIA), and treat" program in a single or two visits.

结局指标
主要结局
Differences in sensitivity and specificity of VIA examination (control) and digital VIA to detect cervical cancer and pre-cancer
时间窗: up to 12 months
Sensitivity and specificity will be calculated using histological results as gold-standard. All lesion Cin2 and worse will be considered as pathological.
次要结局
- Overall agreement between diagnoses based on VIA examination (control) and diagnoses for the same patient based on digital VIA.(up to 12 months)
