Women taking HPV vaccine need only two HPV screening tests for rest of their lives: Research

Women who have had the human papillomavirus (HPV) vaccine could need only two HPV screening tests for the rest of their lives according to new calculations being presented at the NCRI Cancer Conference in Liverpool.

HPV testing is a more accurate cervical screening method than the current smear test, which looks for abnormal cells.

Professor Peter Sasieni, a Cancer Research UK scientist at Queen Mary, University of London, will urge the UK governments to consider making HPV testing the main method of cervical screening across the health service as a priority.

He believes women who have been vaccinated will no longer have to go for screening every three to five years, as is the current practice.

Research suggests that the HPV vaccine will prevent at least seven out of 10 cervical cancers and new vaccines currently being evaluated should prevent even more. It typically takes over 10 years for a cancer to develop after HPV infection. Research shows that cancer caused by HPV types not prevented by the current vaccines take even longer. This could allow the first cervical screen to be safely offered much later than at age 20 or 25.

Professor Sasieni said: "The UK cervical screening programme has done a fantastic job in reducing cervical cancer, but it is based on an old screening test. HPV testing could prevent an even greater proportion of cervical cancer with just half the number of screens over a lifetime. If HPV testing were to be rolled out from next year, it could be used nationally by 2015.

"With continued high coverage of HPV vaccination and targeting of screening resources towards unvaccinated women, cervical cancer should become a truly rare disease. And if the government plan for this change now, they could save hundreds of millions of pounds in the long run."

Cervical cancer is the second most common cancer among women under the age of 35, and the majority of cases are caused by two strains of HPV, types 16 and 18.

In the UK, girls aged 12 to 13 are offered the HPV vaccine. Girls have three injections over six months given by a nurse. A two year catch up programme also started in autumn 2008 to vaccinate girls aged between 13 and 18.

Dr Lesley Walker, Cancer Research UK's director of cancer information, said: "HPV vaccination has been a huge step towards reducing the number of women that will be diagnosed with cervical cancer in future years. And the very high uptake of the vaccine in the UK has been a real success story.

"This is exciting and poses interesting questions for the screening programme in terms of the best way to screen women in the future who have been vaccinated.

"But for now it remains vitally important that all women continue to take up the invitation to go for screening when they receive it."
