New technology could revolutionize prostate examination
There are some types of cancer that occur particularly often in men and pose a serious threat to their health. These include prostate cancer, which is one of the most common cancers in men. British researchers have now developed a diagnostic tool that can smell prostate cancer in men in the urine.
Many men fear prostate cancer. About three out of a hundred German men die from this cancer. It is important to detect the cancer early, before metastasis can take place, to enable successful treatment. Until now, a regular unpleasant prostate examination by a urologist was necessary for this. Scientists from the “University of Liverpool” and the “University of the West of England” (UWE Bristol) have now developed a new diagnostic tool that is able to “smell” prostate cancer in the urine. The researchers published their results in the Journal of Breath Research.
"Odoreader" device could save patients from unpleasant prostate examination
British researchers have developed a non-invasive diagnostic tool. This so-called "odoreader" device can "smell" prostate cancer in the urine. The diagnosis tool could be used by men who are at increased risk of prostate cancer, the doctors explain. The device works like an electronic nose. It identifies different patterns of urological cancer compounds in patients' urine. The urine samples taken are inserted into a device and an algorithm then determines possible cancer, the researchers explain. The positioning of the prostate, which is close to our bladder, gives the urine profile a different expression when a man has cancer, says Professor Norman Ratcliffe of the "UWE Bristol"
"Odoreader" detects prostate cancer with an accuracy of 95 percent
In the study, the researchers tested the device on 155 men. A total of 58 men had prostate cancer. 24 subjects had bladder cancer and 73 men had no cancer. The new device identified prostate cancer in the samples with an accuracy of 95 percent, the scientists say. Bladder cancer was even found to be 100 percent. The researchers believe that diagnostics will revolutionize in the future if the device is successfully registered. There is currently no more accurate test for prostate cancer, the researchers explain. Current tests would often give false alarms. The inaccuracy of the current PSA test indicators could lead to unnecessary biopsies, said Prof. Ratcliffe. The goal was to develop a test that, when diagnosed for the first time, can determine in a non-invasive manner whether patients have cancer, the researcher explains.
New technology needs to be more user-friendly to get the best results
It is imperative to identify these cancers at an early stage because it will make them easier to treat. The next step is to make the new technology more user-friendly, the researchers explain. Then the "odoreader" could be used where it is needed most, for example directly at the patient's bed or in a doctor's office, says Professor Chris Probert. So the fastest, cheapest and most precise results can be expected, adds the doctor. (as)
