Cervical cancer – A single vaccine could benefit most women

23.09.2003


The risk of developing cervical cancer by women infected with the Human Papillomavirus (HPV) is essentially the same no matter which type of virus is involved, provided it belongs to the group of 15 or so that are currently identified as high risk, a scientist said today.



Speaking at ECCO 12 – The European Cancer Conference in Copenhagen, Dr. Xavier Bosch, of the Institut Català d’Oncologia, Barcelona, Spain, said that testing with a cocktail of the majority of high risk type virus would provide a sufficient answer for clinical guidance, and be important to the success of any future screening or vaccination programmes.

HPV is an extremely common sexually transmitted infection. In many cases the infections are harmless and go away without the need for treatment.


But persistent infection with certain types of HPV increases the risk of cervical cancer. These types can be detected in 90-100% of cases of cervical cancer, as opposed to 5-20% of controls. These types are believed to be a necessary cause of cervical cancer and this provides a strong rationale for their use in screening and for the development of anti-HPV vaccines.

"Women who are not infected persistently with one of the cancer-causing types of HPV do not develop cervical cancer", said Dr. Bosch, "and this knowledge is helping us develop effective prevention programmes."

Dr. Bosch and colleagues derived their specific risk estimates from studying a pool of evidence collected by IARC, the International Agency for Research on Cancer, based in Lyon, France. In Europe it is estimated that 65000 new cases of cervical cancer are diagnosed each year, of which 21000 eventually lead to death. HPV carriers are typically young and sexually active, and evidence suggests that males and females are equally likely to be carriers. "In Europe and North America a vaccine including HPV 16 and 18 – the most common high risk types of the virus – would prevent 72% of cases among the vaccinated", said Dr. Bosch. "A vaccine containing types 16,18,33,31 and 45 would cover 84% of the cases."

HPV vaccinations are still in the experimental stage, and the vaccine would be expensive at introduction, said Dr. Bosch. "But the gains in the longer term would be huge, both in terms of healthcare costs and in women’s quality of life. In the meantime, participation in effective screening programs, particularly if they includes HPV testing, can detect and prevent many potential cases of cervical cancer at a very early stage."

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
