Since the introduction of organised screening in Sweden in the 1960s, the number of women being diagnosed with and succumbing to cervical cancer has fallen dramatically. Screening, where a sample of cells is collected from the cervix and examined under an optical microscope, detects early cell changes so that they can be treated before they cause cancer.
However, despite intensive screening 250 women still die from cervical cancer each year in Sweden, and a further 500 develop the disease.
The sensitivity of the current test is low, which means that cell samples must be taken at least every three years. A large number of tests must also be repeated because of unreliable results – something which causes anxiety among patients and additional costs for the health service.
Researchers at Sahlgrenska Academy, University of Gothenburg have now developed a complementary test capable of minimising the number of missed cancer cases.
"Around 70 per cent of all cervical cancer cases are caused by two specific virus types, known as HPV16 and HPV18. We have developed a method that identifies proteins of these oncogenic viruses in cells, enabling a more objective interpretation of the test results," explains Maria Lidqvist, a doctoral student, who presents the method in her thesis.
"This method can hopefully produce a more reliable diagnosis in uncertain cases and reduce the number of missed cancer cases, as well as the number of women who have to be re-called because of cell samples that are difficult to interpret."
The research behind this method has been financed by the Swedish Research Council and conducted at Sahlgrenska Academy, University of Gothenburg, in collaboration with Fujirebio Diagnostics AB in Gothenburg.

The Light: Global study gets underway with online user survey
Light has a fundamental impact on our sense of well-being and performance. In cooperation with Zumtobel, a supplier of lighting solutions, Fraunhofer IAO has launched a global user survey of lighting quality in offices. The objective is to identify the best lighting conditions for a variety of spaces and lighting ...
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data
Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology.
However, their capacity is limited, because the pulses of light need to be lined up one after the other in ...
NASA's Hurricane and Severe Storms Sentinel airborne mission known as HS3 wrapped up for the 2013 Atlantic Ocean hurricane season at the end of September, and had several highlights. HS3 will return to NASA’s Wallops Flight Facility in Wallops Island, Va., for the 2014 Atlantic hurricane season.
During the 2013 mission, two unmanned Global Hawks flew from Wallops for the first time. The mission highlights included studying the Saharan Air Layer, following the genesis of a tropical storm, finding a unique hybrid core or center circulation in a redeveloped storm, obtaining measurements on the strongest side of ...
