Study reveals 2/3 of prostate cancer patients do not need treatment

25.09.2009
In the largest study of its kind, the international team of pathologists studied an initial 4,000 prostate cancer patients over a period of 15 years to further understanding into the natural progression of the disease and how it should be managed. The research, published in the British Journal of Cancer, could be used to develop a blood test to distinguish between aggressive and non-aggressive forms of prostate cancer.

Globally, prostate cancer is the fifth most common malignancy and accounts for 13% of male deaths in the UK. Studies have shown that men with non-aggressive prostate cancer can live with the disease untreated for many years, but aggressive cancer requires immediate treatment.

Pathologists found that the presence of a protein, called Hsp-27, in cancer cells was an indicator that the disease will progress and require treatment. The study showed, however, that in more than 60% of cases the protein was not expressed and the cancer could be managed by careful monitoring, rather than with active invention methods, such as drug treatment or surgery.

The protein normally has a positive function in the body, helping healthy cells survive when they are placed under 'stressful' conditions, such as disease or injury. If the protein is expressed in cancer, however, it can prevent the diseased cells from dying, allowing the cancer to progress. The team, supported by Cancer Research UK (CRUK) and in collaboration with scientists in London and New York, found that the protein can be used to predict how the disease will behave and could help doctors advise patients on how the disease could affect their daily lives.

Professor Chris Foster, Head of the University's Division of Pathology, explains: "Cancer of any kind is a very distressing disease and has the ability to impact on every aspect of a person's life. Chemotherapy and surgery can also have a significant effect on health and wellbeing and that is why it is important that we first understand the biological nature of the disease and how it will behave in each individual patient, before determining if and when a person needs a particular type of treatment.

"By studying the disease in a large number of men throughout the UK and over a long period of time, we have been able to get a more complete picture of how to manage the disease successfully, whilst limiting the negative impact it can have on a patient's life. The study also demonstrates the role of modern of Pathology, not only in establishing diagnoses but in determining if the subsequent management of individual patients is biologically appropriate for their particular condition.

"The protein – or biomarker – we have identified provides us with a signal that the disease will continue to progress. We know that at the point this marker is expressed, medics need to administer treatment to kill the cancer cells. We have shown that in the majority of cases, however, this marker is not expressed and therefore patients do not necessarily need to go through treatment to lead a normal life."

Notes to editors:

1. Patients looking for more information about the new test should discuss the procedure with a Consultant Urologist. Currently, the test can be performed after the patient has undergone a biopsy. Scientists are now working to allow the test to be conducted by blood test.

2. Pathology research at Liverpool is internationally renowned. The division provides services in diagnostic pathology to the Royal Liverpool and Broadgreen University Hospitals Trust as well as offering services in specialised fields of pathology to several other hospitals in the North of England.

3. Cancer Research UK is the world's leading independent organisation dedicated to cancer research. The organisation supports research into all aspects of cancer through the work of more than 4,500 scientists, doctors and nurses.

4. The BJC is owned by Cancer Research UK. Its mission is to encourage communication of the very best cancer research from laboratories and clinics in all countries. Broad coverage, its editorial independence and consistent high standards have made BJC one of the world's premier general cancer journals. www.bjcancer.com.

5. The University of Liverpool is a member of the Russell Group of leading research-intensive institutions in the UK. It attracts collaborative and contract research commissions from a wide range of national and international organisations valued at more than £93 million annually.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

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,...
