Objective:
The purpose of this study was to determine the prevalence of cervical disease, human papillomavirus infection, and human papillomavirus (HPV) genotypes in indigenous villages of Guyana.
Study Design:
This is a retrospective analysis of a clinical cervical cancer screening and treatment program: 2250 women underwent cytologic screening; 1423 women were concomitantly screened for HPV. HPV genotyping was performed in 45 women with high-grade dysplasia and in 9 women with cervical carcinoma.
Results:
We found invasive cervical carcinoma in 0.80% of the women, cervical intraepithelial neoplasia II and III in 5.07% of the women, and a high-risk HPV infection rate in 19.3% of the women, all of which peaked between the ages of 20-30 years. Sixteen genotypes were detected in women with high-grade dysplasia or cancer: HPV 31, 25.0%; HPV 16, 22.7%; HPV 18, 13.6%. The rate of HPV 16 and 18 in cervical cancer was 55.50%.
Conclusion:
Indigenous Guyanese women have a high rate of cervical cancer and high-grade dysplasia, with an apparent predominance of HPV 16 and 18 in invasive cancer and overrepresentation of HPV 31 in high-grade dysplasia.
