New blood test detects 90% of aggressive prostate cancer cases, beating current screenings

A caller trial could make it easier to observe high-risk prostate cancer cases earlier.

The humor test, called Stockholm3, is showing committedness successful clinical trials, beating retired nan traditional, modular prostate-specific antigen (PSA) test.

In a caller study published successful nan Annals of Internal Medicine, researchers from nan Karolinska Institutet successful Sweden studied nan test’s efficacy successful much than 12,000 men – mostly Swedish aliases European – aged 50 to 74.

NEW PROSTATE CANCER TEST PINPOINTS DISEASE BETTER THAN PSA OPTION, STUDY FINDS

All participants were tested pinch PSA and Stockholm3 and were followed for 2 years. During nan follow-up period, 443 men were diagnosed pinch aggressive prostate cancer.

Stockholm3 detected 90% of fierce prostate crab cases compared to 74% for PSA tests.

Stockholm3 missed "significantly fewer" superior cancer cases than PSA. The number of men incorrectly classified arsenic high-risk was akin crossed some tests, according to a property release.

Thorgerdur Palsdottir, a interrogator astatine nan Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, wrote successful a connection that 1 of nan awesome challenges successful prostate crab is being capable to place nan cases that are "truly dangerous."

"Our results show that Stockholm3 identifies importantly much fierce crab cases than PSA, without expanding nan number of unnecessary follow-ups," she said.

"These results constituent toward a imaginable alteration successful really prostate crab screening tin beryllium conducted," nan interrogator added. "A much precise humor trial could alteration earlier discovery of fierce illness while reducing nan number of unnecessary follow-up examinations and procedures."

"It leads to invasive and costly follow-up testing, contributes to over-diagnosis of non-aggressive cancers and, astir importantly, it misses a important stock of aggressive disease," Vigneswaran said.

"The extremity of screening is to find nan cancers that request curen while they are still curable, without raising nan number of men who surface affirmative but don’t person fierce disease," he said.

The trial estimates a man's consequence of fierce prostate cancer, but a biopsy remains nan golden modular for confirming nan disease.

The institution plans to activity FDA support to usage nan trial for regular screening and will "generate nan grounds needed to support that pathway, including U.S. data," Vigneswaran said.
