Evaluation of cervical screening in rural North India

Objective

To assess the accuracy of cervical screening with visual inspection and cytology testing, and the cure rate of cervical intraepithelial neoplasia (CIN) after treatment, in a rural population in North India.

Methods

A cross-sectional study evaluated the detection rates of CIN 2 and CIN 3 lesions by cytology testing and by visual inspection of the cervix following the application of 5% acetic acid (VIA) or Lugol's iodine (VILI). It also evaluated the cure rates following treatment of CIN.

Results

Of 5050 women approached in 17 villages, 3000 (59.4%) participated (range, 41%-91%). Of these, 14.2% were positive by VIA, 15.6% by VILI, and 5.4% by cytology testing at ASCUS threshold, and 37 women were diagnosed as having CIN 1 and 20 as having CIN 2 or CIN 3. Detection rates of CIN 2 or 3 using VIA, VILI, and cytologic findings of ASCUS and LSIL were 3.7, 3.3, 4.5, and 4.2 per 1000 women, respectively, and 91.4% of the treated women were cured.

Conclusion

Both VIA and VILI were found to be accurate screening tests and the cure rates for CIN were satisfactory.
