Blood Test Shows Early Cancer Detection Years Before Diagnosis
A new study indicates that genetic material shed by tumors can be identified in the bloodstream up to three years before a cancer diagnosis. This finding offers a meaningful window for early intervention and possibly more effective treatment.
Yuxuan Wang,assistant professor of oncology at Johns Hopkins University School of Medicine and lead author of the study,expressed surprise at the ability to detect cancer-derived mutations so early. Wang said the early detection of cancer provides a crucial possibility for intervention when tumors are less advanced and more curable. The research highlights the potential of early cancer detection and its impact on treatment outcomes.
Researchers, seeking to determine how early cancers could be detected before clinical signs appear, analyzed plasma samples from the Atherosclerosis Risk in communities (ARIC) study. This National Institutes of Health-funded study investigates risk factors for cardiovascular diseases.
The team used advanced sequencing techniques to analyze blood samples from 26 ARIC participants diagnosed with cancer within six months of sample collection, comparing them to 26 similar participants without a cancer diagnosis. The study focused on early cancer detection through blood analysis.
Of the 52 participants, eight tested positive on a multicancer early detection (MCED) test at the time of blood collection. All eight were diagnosed within four months. for six of these individuals, additional blood samples collected 3.1-3.5 years prior to diagnosis were assessed. Tumor-derived mutations were identified in earlier samples from four of these cases, further emphasizing the potential for early cancer detection.
This study shows the promise of MCED tests in detecting cancers very early, and sets the benchmark sensitivities required for their success.
bert Vogelstein, professor of oncology and co-director of the Ludwig Center at Johns Hopkins, emphasized the promise of multicancer early detection (MCED) tests. Nickolas Papadopoulos, professor of oncology and ludwig Center investigator, added that detecting cancers years before clinical diagnosis could lead to more favorable outcomes, though appropriate clinical follow-up is necessary after a positive test. The study underscores the importance of early cancer detection for improved patient management.
What’s next
Further research is needed to determine the appropriate clinical follow-up for individuals with positive early cancer detection tests. Understanding the long-term impact of early intervention on patient outcomes will also be crucial.
