Key Terms

multi-biomarker, methylation, biomarker, false-positive, +4 more

8 terms

multi-biomarker medical

"Multi-biomarker approach enables broader and earlier cancer detection"

A multi-biomarker is a test or panel that measures several biological indicators—such as proteins, genes, or metabolites—at once to give a fuller picture of a person’s health status or disease risk. For investors, these panels matter because they can improve diagnostic accuracy, guide treatment decisions, and create broader commercial and regulatory value than single-marker tests, much like a multi-sensor dashboard gives a clearer readout than a single gauge.

methylation medical

"combining methylation (M) and protein (P) biomarkers improves cancer detection"

Methylation is a chemical process where small tags called methyl groups attach to DNA or proteins, altering how genes are read without changing the underlying genetic code. Investors monitor methylation because patterns can serve as diagnostic markers, drug targets, or measures of treatment response in biotech and healthcare—think of them as sticky notes or light switches that change biological behavior and can affect a product’s development, approval and market value.

biomarker medical

"each biomarker contributing independently to overall performance"

A biomarker is a measurable indicator found in the body, such as in blood or tissues, that provides information about health, disease, or how the body responds to treatment. For investors, biomarkers can signal the potential success or risk of medical products or therapies, influencing the value of related companies and industry trends. They act like signals or clues that help assess the progress of medical advancements and their market impact.

false-positive medical

"Notably, none of the 2.6% false-positive results were positive for both biomarkers."

A false-positive is a test or signal that indicates a problem or event exists when it actually does not — like a smoke alarm sounding without a fire. In finance and regulation, false-positives can be faulty lab results, screening flags, or compliance alerts that wrongly suggest risk or success, prompting unnecessary costs, paused projects, or misleading investor reactions that can move a company’s stock price.

multi-cancer early detection medical

"multi-cancer early detection (MCED) program supporting the commercially available Cancerguard test"

A multi-cancer early detection test is a medical screening tool—often a simple blood test—that looks for biological signals, such as abnormal DNA or protein patterns, that could indicate many different cancers before symptoms appear. For investors it matters because successful tests can reshape demand for diagnostics, influence healthcare spending and insurance coverage, and create new revenue streams or risks for companies across diagnostics, treatment and screening services; think of it as a smoke alarm that can warn of problems throughout an entire house rather than just one room.

prospective interventional trial medical

"the first large prospective interventional trial of a blood-based MCED test"

A prospective interventional trial is a planned medical study that enrolls participants and gives them a specific treatment or procedure to see how it works over time. For investors, the results matter because these trials provide forward-looking evidence about safety and effectiveness that regulators, doctors and patients use to decide whether a product can be approved, adopted or generate revenue—think of it like a carefully run test drive that determines commercial fate.

median follow-up medical

"after a median follow-up of approximately four years, all patients treated..."

Median follow-up is the middle value of how long patients in a clinical study have been observed, meaning half were followed for a shorter time and half for a longer time. For investors, it signals how mature the trial data are—like checking how long a sample of trees has been watched to judge growth—so longer median follow-up generally gives more reliable information about treatment durability, side effects and long-term outcomes.

stage I or II cancers medical

"all patients treated for stage I or II cancers remained alive and cancer-free"

Stage I or II cancers are early-stage tumors that are generally confined to the original organ or have only limited local spread, like a small fire contained to one room rather than the whole building. For investors, this matters because early-stage disease often has better patient outcomes, different treatment approaches and smaller but more stable market needs, and it affects the potential size, pricing and regulatory pathway for therapies and diagnostics.

Data show how a multi-biomarker class approach improves early-stage cancer detection
AACR will also recognize landmark DETECT-A study publication reporting long-term outcomes supporting the clinical impact of MCED

ABBOTT PARK, Ill., April 17, 2026 /PRNewswire/ -- Abbott (NYSE: ABT) will present new data at the American Association for Cancer Research (AACR) Annual Meeting 2026 demonstrating continued advancements in its multi-biomarker, multi-cancer early detection (MCED) program supporting the commercially available Cancerguard® test. Additionally, the AACR Cancer Prevention Research Award for Outstanding Journal Article will recognize a publication on MCED multiyear outcomes from the DETECT-A study.

Multi-biomarker approach enables broader and earlier cancer detection
New data demonstrate how combining methylation (M) and protein (P) biomarkers improves cancer detection across stages, with each biomarker contributing independently to overall performance. Cancerguard is currently the only commercially available MCED test designed with a multi-biomarker class approach, combining methylation and protein signals to improve detection.

In a prospectively collected case-control study, nearly half of positive cancer signals were driven by methylation alone (47.1%), with additional detection from protein-only (7.4%) and combined biomarker signals (45.5%), supporting broader detection across cancer types and stages.¹ In early-stage disease, many cancer signals were detected by a single biomarker class, demonstrating how each contributes uniquely to overall detection. Notably, none of the 2.6% false-positive results were positive for both biomarkers.¹

"We designed Cancerguard as the first-of-its-kind multi-biomarker test because no one signal tells the whole story," said Tom Beer, M.D., chief medical officer, multi-cancer early detection, Abbott's cancer diagnostics business. "By combining biomarkers, we can detect cancer earlier, when it matters most."

AACR recognizes impactful MCED research with journal award
The AACR Cancer Prevention Research Award for Outstanding Journal Article will be presented to the authors of a 2024 Cancer Prevention Research publication reporting multi-year outcomes from the DETECT-A study, the first large prospective interventional trial of a blood-based MCED test. The study identified nine cancer types, including several without routine screening, and showed that, after a median follow-up of approximately four years, all patients treated for stage I or II cancers remained alive and cancer-free.^2,3

The award recognizes the significance of these multi-year outcomes data in advancing evidence for the clinical impact of MCED, an area where long-term outcomes data have historically been limited.

"Long-term follow-up provides critical insight into how multi-cancer early detection can shape the future of cancer screening," said Beer. "With nearly 70 percent of cancers occurring in types without recommended screening, these findings highlight the potential for MCED to increase early detection and improve outcomes."⁴

About the DETECT-A study
The DETECT-A (Detecting cancers Early Through Elective mutation-based blood Collection and Testing) study was the first-ever large, prospective, interventional study to use a blood test to detect multiple types of cancer in a real-world setting. The DETECT-A study enrolled more than 10,000 women with no history of cancer to determine if a blood test in combination with standard-of-care screenings could detect cancers before signs and symptoms appeared. The CancerSEEK test, the MCED test studied in DETECT-A, was the forerunner to the Cancerguard test.

About the Cancerguard test
Cancerguard is a laboratory-developed test (LDT) designed to detect multiple cancers, including the most aggressive cancers, in early stages from a simple blood draw. It integrates two classes of biomarkers to enable broader detection and follows a streamlined, imaging-based diagnostic pathway to help reduce unnecessary follow-up procedures. Developed with high specificity to minimize false positives, the test helps detect a wide range of cancers, including those that lack guideline-recommended screening options.⁵ The Cancerguard test has not been cleared or approved by the U.S. Food and Drug Administration or any other regulatory authority.
