🐾 Liver Tumors and Cancers in Dogs and Cats: Veterinary Insights for 2025 🐶🐱
Understanding liver tumors in pets is crucial for timely diagnosis and effective treatment. In this comprehensive guide, Dr. Duncan Houston BVSc delves into the types, diagnostics, and care options for liver tumors in dogs and cats as of 2025.
🔬 Understanding Liver Tumors
Liver tumors in pets can be classified as:
- Primary Tumors: Originating in the liver.
- Secondary Tumors: Metastatic tumors spreading from other organs.
Types of Primary Liver Tumors:
- Hepatocellular Tumors: Includes hepatocellular carcinoma (common in dogs) and hepatocellular adenoma (common in cats).
- Bile Duct Tumors: Biliary adenoma (benign) and biliary carcinoma (malignant).
- Neuroendocrine Tumors: Rare and often diffuse, with a poor prognosis.
- Mesenchymal Tumors: Includes hemangiosarcoma, fibrosarcoma, and others.
🩺 Diagnostic Journey
Diagnosing liver tumors involves a series of steps:
- Clinical Signs: Observing symptoms like lethargy, weight loss, or jaundice.
- Laboratory Tests: Blood tests to assess liver function.
- Imaging: Ultrasound is pivotal in evaluating liver texture and identifying tumors.
-
Sampling:
- Needle Aspirate: Less invasive, provides cell samples.
- Biopsy: More invasive, provides tissue architecture for detailed analysis.
⚠️ Metastatic Liver Cancer
Secondary liver tumors are more common than primary ones, often spreading from the spleen, pancreas, or intestines. Prognosis is generally poor, and treatment depends on the primary cancer type.
🛠️ Treatment Options
Treatment varies based on tumor type and progression:
- Surgical Removal: Preferred for massive tumors, especially hepatocellular carcinoma.
- Supportive Care: For non-surgical cases, focusing on quality of life.
- Chemotherapy: Limited effectiveness, used in specific cases.
📊 Prognosis
Prognosis depends on various factors:
- Hepatocellular Carcinoma: Massive tumors have better outcomes post-surgery.
- Biliary Carcinoma: Aggressive with a high metastasis rate; median survival is around 6 months post-surgery.
- Neuroendocrine and Mesenchymal Tumors: Generally poor prognosis due to early spread.
