HPV DNA testing for precancers and cervical cancers is over 50 per cent more sensitive than cytology testing for the same conditions a community-based study in Mexico has revealed. Results of the largest HPV DNA primary screening study ever to be performed in a Latin American country point to the readiness of HPV DNA testing for large-scale implementation in Mexico and are published online today (8 July 2010) in Cancer, Causes and Controls.
Attila Lorincz, Professor of Molecular Epidemiology at Barts and The London School of Medicine and Dentistry is among researchers behind the study which involved over 50,000 women, aged 20-70, undergoing routine cytology and high risk (HR) HPV DNA testing. All those who tested positive through cytology were referred to colposcopy, while the HPV DNA positive women were followed by repeat HPV DNA testing with colposcopy if they were repeat positive in one year. The study is a pilot implementation to determine the real world performance of routine HPV DNA testing and routine cytology testing in the Mexican IMSS health insurance system.
