According to a recent study, a novel at-home saliva test for prostate cancer may perform better than existing diagnostic techniques. Researchers have created a straightforward spit test that analyzes genetic variations in a man’s DNA and can be done at home without a doctor’s appointment. According to the new study, the test seems to function better than the present approach for determining prostate cancer risk, which could greatly enhance prostate cancer treatment and early diagnosis. Nowadays, a blood test called the prostate-specific antigen (PSA) test is used to screen for prostate diseases such prostate cancer and enlarged prostates.
The NHS does not provide routine PSA testing, although it is accessible upon request for men over 50 or if a general practitioner suspects prostate cancer. Officials have been evaluating the viability of a prostate cancer screening program in response to growing calls for the test to be implemented throughout the health system. However, some contend that if the test is widely utilized, it may be able to discover cases that did not require treatment or cause issues. According to specialists, the new saliva test might be used as an extra screening tool because it detected a greater percentage of aggressive malignancies than the PSA test and produced fewer false positive findings.
Accordingly, fewer males may be sent for needless testing if the test is used, they continued. Researchers from The Royal Marsden NHS Foundation Trust and The Institute of Cancer Research, London, sought to evaluate the efficacy of a novel instrument they had created known as a polygenic risk score. This risk score determines if a person is at high risk of prostate cancer by evaluating 130 genetic variations linked to an elevated risk of the illness using spit. In the UK, 6,300 men between the ages of 55 and 69 were evaluated using the technique in the latest trial.
During the investigation, 745 individuals (12%) were identified as having a high risk score, which they called Barcode 1. About 468 of these men accepted the invitation to undergo a prostate cancer screening, which included an MRI and a biopsy.
