6 Million New Cancer Cases Per Year in US Dogs
Cancer is by far the single most common cause of death in adult dogs. Like humans, dogs have a 1 in 3 lifetime risk of getting cancer, and approximately 6 million dogs are newly diagnosed with cancer each year in the United States. Older dogs and certain breeds have a higher lifetime risk of cancer and/or have a higher risk of being diagnosed at an earlier age. Cancer in dogs is often diagnosed at an advanced stage, when treatment options are limited, and chances of long-term control or cure are low. Each year, cancer cuts short the lives of many dogs who might have enjoyed many healthy years with their families had the disease been detected earlier.
Cancer is a Disease of the Genome
Each cell in a dog’s body contains billions of DNA “letters” that make up the dog’s genome. Cancer develops as a result of the successive accumulation of genomic alterations (DNA mutations) over time. All cells release DNA fragments into the bloodstream. DNA released from cancer cells contains specific genomic alterations associated with cancer that can be detected by liquid biopsy with the OncoK9 test. (OncoK9 indicates whether cancer is currently present in the body; it does not indicate risk for future cancer development.)
OncoK9: The Liquid Biopsy Test for Dogs
As a first-in-class multi-cancer early detection (MCED) test, OncoK9 employs cutting-edge genomic analysis that leverages next-generation sequencing (NGS) technology and proprietary bioinformatics algorithms, empowering veterinarians to provide superior care to canine patients.
Simple
Blood Draw
learn more
Most cancer tests are either invasive (like a tissue biopsy) or require special equipment (like imaging). OncoK9 requires only a simple blood draw. The sample collection can take place during the same visit when the veterinarian prescribes the test.
Multi-Cancer
Coverage
learn more
OncoK9 has demonstrated cancer signal detection in 30 different cancer types, including 8 of the most common cancers in dogs.
Cutting-Edge
Technology
learn more
OncoK9 interrogates millions of cell-free DNA fragments in each blood sample, using sophisticated next-generation sequencing technology and bioinformatics algorithms to detect genomic alterations associated with cancer.
Early
Detection
learn more
By identifying cancer signal in cell-free DNA extracted from a blood sample, OncoK9 may allow for earlier detection of cancer, before the onset of clinical signs.
OncoK9: CANDiD Study
The international, multi-center clinical study demonstrated that OncoK9® – The Liquid Biopsy Test for Dogs™ can detect 30 different types of cancer with a simple blood draw. The CANDiD study included blood samples collected prospectively from more than 1,000 client-owned dogs at more than 40 clinical sites across the United States, Canada, Brazil, the Netherlands, France, and Hong Kong between 2019 and 2021.
Results of the CANDiD Study – the largest clinical validation study ever performed in veterinary cancer diagnostics – were recently submitted to a leading peer-reviewed journal, and a summary of the findings is available in a white paper.
OncoK9: How the Liquid Biopsy Test Works
Step 1
A blood sample is collected that contains cell-free DNA fragments released from healthy cells and cancer cells (if cancer is present).
Step 2
A centrifuge is used to separate the blood sample into 3 components: plasma, buffy coat, and hematocrit.
Step 3
Cell-free DNA is extracted from plasma and an amplified DNA library is prepared for sequencing.
Step 4
Next-generation sequencing of the DNA library generates detailed data for analysis.
Step 5
The lab uses proprietary bioinformatics algorithms to identify cancer-associated genomic alterations.
Step 6
A clinical report is sent to the veterinarian indicating whether or not cancer signal has been detected.
All OncoK9 testing and interpretation steps are performed at the PetDx central laboratory in San Diego, California (ISO 9001:2015 Certificate Nr. 1807). Two state-of-the-art Illumina NovaSeq 6000 Next-Generation Sequencing instruments are used for the high-complexity testing required to generate OncoK9 results.
OncoK9: Intended Use
OncoK9 is a multi-cancer early detection (MCED) test for the detection and characterization of cancer-associated genomic alterations in DNA isolated from canine whole blood samples, using next-generation sequencing (NGS) technology. OncoK9 is intended for use in dogs who are at higher risk of cancer. As with any laboratory test, OncoK9 results should be interpreted by a veterinarian in the context of each patient's medical history and clinical presentation.
OncoK9: Annual Screening
OncoK9 is recommended as an annual screening test for all dogs starting at 7 years of age and starting at younger ages for dogs belonging to breeds in which cancer tends to develop earlier in life.
OncoK9: Aid-in-Diagnosis
OncoK9 is recommended as an aid-in-diagnosis for dogs in which cancer is suspected based on clinical signs or other clinical findings.
OncoK9: Limitations & Risks
OncoK9 requires a blood collection performed under the care of a licensed veterinarian, and test results are returned to the veterinarian for communication to the pet owner. As with any laboratory test, OncoK9 results should be interpreted by a veterinarian in the context of each patient's medical history and clinical presentation. Test failures and false positive or false negative results may occur. To review OncoK9 disclosures, please visit the OncoK9 Test Limitations & Risks web page.
As an oncologist, I am excited about the ways in which the OncoK9 liquid biopsy test will benefit dogs, their families, and the veterinarians that manage their care.
