PURPOSE: Via a large population-based survey conducted in rural, southwestern China, we aim to evaluate the effect of visual inspection with acetic acid/Lugol's iodine (VIA/VILI) on diagnosing cases of cervical cancer and of pre-cancerous lesions while exploring the mode of cervical prevention and control in low-resource settings in China.
METHODS: Women aged 30-59 years from Chongqing, China were recruited from 2006 to 2009. Participants underwent VIA/VILI, and, if positive, received colposcopy-directed or random biopsies. Women with negative VIA/VILI or biopsy-confirmed cervical intraepithelial neoplasia (CIN) 1 lesions diagnosed in the first round of screening were re-screened in the following year with the same procedure.
RESULTS: In total, 10,269 women received VIA/VILI. The average age of participants was 40.9 ± 7.6 years. Overall, 0.85% (87/10,269) of women were diagnosed via pathology-confirmed biopsy with CIN1, 0.25% (26/10,269) with CIN2, 0.27% (28/10,269) with CIN3, and 0.02% (2/10,269) with cervical cancer. Over half (57.7%) of CIN2 lesions, the majority of CIN3 lesions (89.3%), and all cancer cases (100%) were detected in the first round of screening.
CONCLUSION: In a rural, low-resource setting in China, one-time VIA/VILI screening detected more than a half of CIN2 cases, most CIN3 cases and all the cervical cancer cases. Detection rates of CIN2 lesions significantly increased with a 1-year follow-up VIA/VILI screen. Therefore, if multiple cervical cancer screenings are not feasible logistically or financially, a one-time VIA/VILI may be the most efficient strategy to detect cervical cancer and most CIN3 lesions in women in low-resource settings.
