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: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
