New test may improve cervical cancer detection

23.11.2012
Routine smear tests have considerably reduced the number of cases of cervical cancer, but despite intensive screening 250 women in Sweden still die from the disease every year. Researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, have developed new methods of minimising the number of missed cases and making diagnosis more reliable.
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.

Im Focus: Self-assembling nano inks form conductive and transparent grids during imprint

Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers at INM – Leibniz Institute for New Materials have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.

To print the grids, an ink of gold nanowires is applied to a substrate. A structured stamp is pressed on the substrate and forces the ink into a pattern. “The...

Im Focus: Neues Forschungsnetzwerk für Mikrobiomforschung

Mikroben und Viren haben weitreichenden Einfluss auf die Gesundheit von Mensch und Tier. Die neu gegründete "Austrian Microbiome Initiative" (AMICI) fördert die nationale Mikrobiomforschung und vernetzt MedizinerInnen und ForscherInnen verschiedenster Fachrichtungen zur Nutzung von Synergien.

Bakterien, Archaeen, Pilze, Viren – Milliarden von Mikroorganismen leben in Symbiose in und auf Menschen und Tieren. Diese mikroskopisch kleinen Lebewesen...

Im Focus: Superschneller Internetfunk dank Terahertz-Strahlung

Wissenschaftler aus Dresden und Dublin haben einen vielversprechenden technologischen Ansatz gefunden, der Notebooks und anderen mobilen Computern in Zukunft deutlich schnellere Internet-Funkzugänge ermöglichen könnte als bisher. Die Teams am Helmholtz-Zentrum Dresden-Rossendorf (HZDR) und am irischen Trinity College Dublin brachten hauchdünne Schichten aus einer speziellen Verbindung von Mangan und Gallium dazu, sehr effizient Strahlung im sogenannten Terahertz-Frequenzbereich auszusenden. Als Sender in WLAN-Funknetzen eingesetzt, könnten die höheren Frequenzen die Datenraten zukünftiger Kommunikations-Netzwerke spürbar erhöhen.

„Wir halten diesen Ansatz für technologisch sehr interessant“, betont Dr. Michael Gensch, Leiter einer Arbeitsgruppe am HZDR, die sich mit den...

Im Focus: Newly discovered material property may lead to high temp superconductivity

Researchers at the U.S. Department of Energy's (DOE) Ames Laboratory have discovered an unusual property of purple bronze that may point to new ways to achieve high temperature superconductivity.

While studying purple bronze, a molybdenum oxide, researchers discovered an unconventional charge density wave on its surface.
