Why OncoK9 Was Performed

Cancer was suspected and oncology referral was advised, however the owner was hesitant to pursue oncology consult and preferred to start with non-invasive testing.

OncoK9 Result

Cancer Signal
Cancer Signal Detected
Detected
  • A Cancer Signal Detected result significantly increases the likelihood that cancer is present, but does not confirm the presence of cancer. This result should not be used as the sole basis for making important decisions such as treatment or euthanasia.
  • A confirmatory cancer evaluation should be performed to establish a definitive diagnosis.

Due to a Cancer Signal Detected OncoK9 result, a Confirmatory Cancer Evaluation was performed.


Comments

Cancer signal origin prediction: hematological malignancy (likely lymphoma or lymphoid leukemia)

Confirmatory Cancer Evaluation

May include any or all of the following:

Exam
Exam
  • Thorough clinical history
  • Thorough physical exam
    • Including oral and rectal exam
Laboratory
Laboratory
  • CBC and Chemistry
  • Urinalysis
Imaging
Imaging
  • Thoracic radiographs – 3 views
  • Abdominal imaging – ultrasound preferred
  • Radiographs of localized areas of bone or joint pain, if present
Sampling
Sampling
  • Tissue sampling of any detected masses or enlarged lymph nodes for pathological analysis

In some cases, advanced imaging (such as CT and/or MRI) may be indicated.
