Winnie presented for lameness in the left hind leg. Radiographs showed an aggressive bone lesion.
Why OncoK9 Was Performed
The veterinarian suspected cancer, however the owners were hesitant to proceed with workup or referral and opted for conservative management while thinking about their options.
- 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.
Confirmatory Cancer Evaluation
May include any or all of the following:
- Thorough clinical history
- Thorough physical exam
- Including oral and rectal exam
- CBC and Chemistry
- Thoracic radiographs – 3 views
- Abdominal imaging – ultrasound preferred
- Radiographs of localized areas of bone or joint pain, if present
- 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.
Cancer Workup & Findings
Histopathology diagnosis: Osteosarcoma in the proximal tibia
- Thoracic radiographs revealed no evidence of metastasis
- At the surgical consultation, amputation was recommended
- The owners decided to proceed with amputation
OncoK9 helped the veterinarian convince the owner to proceed with the recommended clinical management plan.
OncoK9 helped the owner make the decision to pursue amputation. In doing so, a diagnosis was achieved and Winnie’s pain was controlled.
Winnie’s osteosarcoma was diagnosed and she was able to start therapy. Amputation provided immediate pain relief, and also helped Winnie avoid the possibility of a painful pathologic fracture.
