New technique detects early cervical cancer

21.10.2008
The Institute of Cancer Research and The Royal Marsden Hospital have developed a new imaging technique which locates previously undetectable early stage cervical cancers, according to research published in Radiology today (October 21).

The pilot study, funded by Cancer Research UK, found the new imaging technology identified small tumours, reducing the need for radical surgery which could lead to infertility.

Lead researcher Professor Nandita deSouza from The Institute of Cancer Research said the study was extremely optimistic.

“As cervical cancers are usually identified at a very early stage through screening, our imaging technology can localise them and determine the size of the tumour. We can use this information to plan less radical surgery, preserving as much of the uterus and the cervix as possible,” she said.

“With conventional scanning techniques, small tumours are harder to identify or to differentiate from scar tissue, particularly if the patient has had a recent biopsy. In these cases, conventional imaging can overestimate the level of cancer within the cervix and result in major surgery leading to infertility.

“The quality of the information from the images produced using this new method has allowed us to identify and define smaller tumours more accurately, helping us to make decisions on surgery.

“Advancements in scanning and screening techniques for cervical cancer are vital in treatment planning to reduce the number of women who require hysterectomies for cancer treatment.”

The pilot study focussed on 59 women between the ages of 24 and 83 over a period of 22 months.

Prof deSouza said one of the major successes of this work was the exploitation of the diffusion of water around cells in cancer tissue to produce the image, a technique called “diffusion weighted imaging”. This significantly improves the level of contrast between developing tumours and the surrounding tissues.

The new imaging technique involved the use of a vaginal probe to capture images of the cervix which created a much higher image resolution compared to a traditional external pelvic scan.

Encouragingly, researchers found that 88 per cent of tumours could be detected using an internal probe and diffusion-weighted imaging compared with only 77 per cent of the same tumours found using the existing external technique.

Dr Lesley Walker, director of cancer information at Cancer Research UK, which funded the study, said: “This small study is extremely promising and provides a clear rationale for more extensive studies.

“Cancer Research UK has identified imaging research as a priority and we have invested £50 million over five years, in partnership with other funding bodies, to help us achieve our aim of improving the detection and diagnosis of cancer through this exciting field of cancer research.”

Around 2,700 women are diagnosed each year in the UK making it the second most common cancer in women under 35.

Approximately 1,000 women die from cervical cancer in the UK every year.

About 4.4 million women are invited for cervical cancer screening each year in England between the ages of 25 and 60.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
