Objective Rapid, high-volume screening programs are needed as part of cervical cancer prevention in China. Methods In a 5-day screening project in Inner Mongolia, 3345 women volunteered following a community awareness campaign, and self-swabbed to permit rapid HPV testing. Two AmpFire™ HPV detection systems (Atila Biosystems) were sufficient to provide pooled 15-HPV type data within an hour. HPV+ patients had same-day digital colposcopy (DC) performed by 1 of 6 physicians, using the EVA™ system (MobileODT). Digital images were obtained and, after biopsy of suspected lesions for later confirmatory diagnosis, women were treated immediately based on colposcopic impression. Suspected low- grade lesions were offered treatment with thermal ablation (Wisap), and suspected high-grade lesions were treated with LLETZ. Results Of 3345 women screened, 624 (18.7%) were HPV+. Of these, 88.5% HPV+ women underwent same-day colposcopy and 78 were treated. Later consensus histology results obtained on 197 women indicated 20 CIN2+, of whom 15 were detected and treated/referred at screening (10 by thermal ablation, 4 by LLETZ, 1 by referral). Conclusions Global control of cervical cancer will require both vaccination and screening of a huge number of women. This study illustrates a cervical screening strategy that can be used to screen-and-treat large numbers of women. HPV self-sampling facilitates high-volume screening. Specimens can be tested rapidly, promoting minimal loss-to-follow-up. Specifically, the AmpFire™ system used in this study is highly portable, simple, rapid (92 specimens per 65 min per unit), and economical. Visual triage can be performed on HPV+ women with a portable digital colposcope that provides magnification, lighting, and a recorded image. Diagnosis and appropriate treatment remain the most subjective elements. The digital image is under study for deep-learning based automated evaluation that could assist the management decision, either by itself or combined with HPV typing.

ObjectiveImplementation of a novel, rapid, high-volume, see-and-treat cervical cancer screening programme using self-swab human papillomavirus (HPV) testing and digital colposcopy in underserved regions of Yunnan China.Design480–980 women per day self-swabbed for high-risk HPV (hrHPV+). Four careHPV machines (Qiagen) were run simultaneously to test the specimens. All hrHPV+ patients were contacted the same day and digital colposcopy was performed with the enhanced visual assessment system (MobileODT). Digital images were obtained, and all suspected lesions were biopsied and then treated.SettingRural and underserved areas of the Yunnan province, Kunming municipality.Participants3600 women, mean age 50.2 years, who had never been screened for cervical cancer. The women were of the Yi, Hui, Dai and Han ethnicities.InterventionsCryotherapy was performed on all lesions suspicious for cervical intraepithelial neoplasia (CIN) 1 and loop electrosurgical excision procedure was performed on all lesions suspicious for ≥CIN2. Endocervical curettage was performed if the transformation zone was not fully visualised.Results216 women (6%) were hrHPV+. 168 underwent same-day colposcopy (23 CIN1, 17≥CIN2). Digital colposcopy was able to identify 15 of 16 (93.8%)≥CIN2 lesions.ConclusionsThis study illustrates a high-volume, rapid and practical strategy that can be used to screen and treat an ethnically diverse group of Chinese women. First, HPV self-sampling allows large numbers of women to be screened rapidly and relatively inexpensively. Only hrHPV+ women will then require further evaluation. Digital colposcopy is then performed on hrHPV+ women with a portable digital colposcope. The high-resolution images obtained can facilitate appropriate same-day treatment as they are able to accurately distinguish between CIN1 and ≥CIN2 lesions.

Objective Rural Yunnan Province is one of the most ethnically, culturally, and religiously diverse regions in China. The majority of its women have never been screened for cervical cancer. It is not known whether women would feel comfortable and ultimately even prefer using a human papillomavirus (HPV) self-swabbing method. Methods In a 6-day period, 3,600 women were taught the role of HPV in cervical cancer. They were then given self-swabbing instructions. After obtaining their specimens, 600 women were interviewed about their experience with HPV self-testing. The women were of the Yi, Hui, Dai, and Han ethnicities. Results The overwhelming majority of the women surveyed understood the self-sampling instructions (588/600, 98%) and felt comfortable carrying out the self-sampling procedure (584/600, 97%). Significantly more women (389/600, 64.8%) preferred self-sampling to having the provider (211/600, 35.2%) obtain the sample (χ 2 = 105.61, p < .05). Women who preferred self-sampling did so primarily because they felt capable of obtaining the specimens ( n = 80) or that it was a more convenient way to be tested ( n = 79). The medical expertise of the provider ( n = 74) and concerns over the accuracy of the test ( n = 88) shifted some women's preference toward a provider-obtained sample. Conclusions There are 400+ million Chinese women who have never had a cervical cancer screening. Self-testing has the potential to significantly increase the number of women tested. Despite the diversity of the women screened, the majority felt comfortable self-sampling and preferred self-swabbing to provider testing.
