Effectiveness of cryotherapy for histologically confirmed cervical intraepithelial neoplasia grades 1 and 2 in an Indian setting.

Abstract

OBJECTIVE:

To describe the effectiveness of cryotherapy for treating women who were histologically confirmed to have cervical intraepithelial neoplasia (CIN) in India.

METHODS:

Data were analyzed retrospectively from screening projects that collected data from January 2001 to May 2008 in Trivandrum, India. Women with CIN were appropriately treated with cryotherapy by a trained nurse or physician and followed up for cure, adverse events, and complications. Cure was defined as absence of CIN during any follow-up visit at least 1 year after treatment.

RESULTS:

Among 236 women identified with CIN and appropriately treated with cryotherapy, 173 (81.6%) were followed up (158 CIN 1 and 15 CIN 2 cases). The percentage cure for CIN 1 and 2 lesions was 93.0% and 86.7% respectively. An odds ratio of 0.2 (95% confidence interval, 0.0-0.9) was observed for treatment received more than 2 months after screening as compared with treatment received within 2 months. Complications were observed in 1.2% of treated women and adverse events (discharge and mild pain) in 26.6%.

CONCLUSION:

The study affirms that trained mid-level providers can appropriately perform cryotherapy in primary healthcare services and that expanding such services in low-resource settings would increase the availability and accessibility of precancer treatment.
