Scientists establish new blood test to better evaluate prostate cancer

01.10.2008
An international study led by researchers at The Institute of Cancer Research will pave the way for a test to be used to better tailor treatments and hopefully extend the survival of men with aggressive forms of metastatic prostate cancer.

The study, to be published tomorrow for Cancer Clinical Research ( available online Oct 1,) has found that this analysis of Circulating Tumour Cells (CTC) can be utilised to study the prognosis of prostate cancer and is an independent indicator for overall survival of the disease.

Lead researcher Dr Johann de Bono at The Institute of Cancer Research and The Royal Marsden Hospital says:

“CTC testing, used in conjunction with the existing prostate specific antigen (PSA) test, may allow doctors to more accurately evaluate the effect of treatment on a patient’s tumour.”

“These studies are a very promising development, allowing cancer cells to be detected using a simple blood test and may eventually allow us to tailor cancer treatments to maximise the benefit for patients. Hopefully this will lead to improving the survival of patients with metastatic prostate cancer.”

The PSA test has been widely adopted as the benchmark test for prostate cancer in the UK, but it is not always possible to identify a clear relationship between a raised PSA level and the status of the disease.

Circulating tumour cells (CTCs) are cancer cells that have broken away from an existing tumour and have entered into the bloodstream. The presence of these cells in the blood provides valuable insights into disease progression.

This study has shown that the monitoring and detection of CTCs can provide valuable information on the patient’s prognosis. Further studies are taking place to evaluate if the CTC test may be used to allow doctors to make treatment decisions more quickly and more reliably for the benefit of patients.

The test has already been incorporated into several prostate cancer drug trials that are taking place at The Institute and The Royal Marsden.

The test has been cleared by the FDA in the United States to determine the prognosis of patients with metastatic breast, colorectal or prostate cancer.

The study was in partnership with the New-York based Memorial Sloan-Kettering Institute and involved 231 patients undergoing chemotherapy treatment. Sixty-five clinical centres in Europe and the U.S. took part in the study.

The patients underwent monthly CTC monitoring to measure the level of circulating tumour cells in the blood. A count of more than 5 CTC per 7.5 ml of blood was seen as an indicator towards an “unfavourable” prognosis whereas a count of less than 5 CTC per 7.5ml was considered “favourable”. This was compared with the progression of the metastatic prostate cancer tumours.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
