Understanding Hemangiosarcoma in Dogs – Key Facts

Hemangiosarcoma in dogs, also known as canine hemangiosarcoma or dog spleen cancer, is an aggressive and incurable form of cancer. This type of cancer develops from the blood vessel lining cells and can occur in various parts of the body, including the spleen, heart, liver, and skin. Hemangiosarcoma is relatively common in dogs, accounting for 5-7% of all tumors seen in dogs. Certain breeds, such as Golden Retrievers, German Shepherd Dogs, and Portuguese Water Dogs, are more susceptible to this disease.

Dogs with hemangiosarcoma often show no symptoms until the tumor has reached an advanced stage and has caused internal bleeding. This is why it is often referred to as a “silent killer.” The prognosis for dogs with hemangiosarcoma is poor, with most dogs surviving only a few months after diagnosis.

The Natural History of Canine Hemangiosarcoma

Canine hemangiosarcoma is an aggressive and mysterious disease that primarily affects the spleen, right atrium of the heart, and subcutis (tissue beneath the skin). The tumor infiltrates the surrounding tissues and has the ability to metastasize to other parts of the body. In the early stages, dogs with hemangiosarcoma may not show any clinical signs or symptoms, making it challenging to diagnose. However, as the tumor grows, it can cause intermittent episodes of internal bleeding, leading to non-specific signs such as lethargy and weakness.

Hemangiosarcoma has a propensity to metastasize to vital organs, including the lungs, liver, intestines, and mesentery. This aggressive cancer often goes undetected until a large or rapidly growing tumor ruptures, causing acute hemorrhage and frequently resulting in death.

To visualize the spread of hemangiosarcoma in dogs, refer to the following diagram:

The table above highlights the common sites where hemangiosarcoma metastasizes. Lungs are the most frequently affected organ, seen in 50-80% of cases, followed by the liver, intestines, and mesentery.

Unfortunately, the natural history of canine hemangiosarcoma is marked by its aggressive behavior and the challenges it poses for early detection and treatment.

Hemangiosarcoma Symptoms in Dogs

Dogs with hemangiosarcoma may initially exhibit no noticeable symptoms, making it difficult to diagnose the disease in its early stages. However, as the tumor progresses and internal bleeding occurs, dogs may display the following non-specific signs:

• Lethargy
• Weakness
• Decreased appetite
• Pale gums

In the words of Dr. Lisa Berg, veterinary oncologist, “Hemangiosarcoma is often considered a ‘silent killer’ because by the time clinical symptoms are apparent, the disease is often advanced, making successful treatment challenging.”

If you notice any of these symptoms in your dog, it’s crucial to seek veterinary care promptly for a thorough evaluation and proper diagnosis.

What Causes Hemangiosarcoma

The exact cause of canine hemangiosarcoma is still unknown, but researchers believe it is influenced by a combination of genetic and environmental factors. Certain breeds show a higher susceptibility to developing hemangiosarcoma, indicating a genetic predisposition to the disease. Mutations in specific genes, such as the tumor suppressor TP53, have been identified in dogs with hemangiosarcoma, suggesting a potential genetic link.

Environmental factors may also play a role in the development of hemangiosarcoma in dogs. Exposure to certain chemicals and toxins has been hypothesized to contribute to the disease. Ongoing research is focused on identifying these genetic and environmental risk factors to better understand the mechanisms behind hemangiosarcoma and possibly develop preventive measures.

These symptoms, although non-specific, can serve as red flags that something is not right with your furry friend. It’s essential to be attentive to any changes in your dog’s behavior or overall well-being.

In some cases, a hemangiosarcoma tumor may rupture, causing acute hemorrhage and sudden collapse in the affected dog. This life-threatening situation requires immediate veterinary intervention.

To diagnose hemangiosarcoma, veterinarians rely on a combination of diagnostic tools and techniques. Imaging techniques such as X-rays, ultrasounds, and echocardiograms can provide valuable information about the presence of a mass and its location within the body.

A definitive diagnosis, however, requires a biopsy and evaluation by a pathologist.

A biopsy involves the removal of a small piece of tissue from the suspected tumor or the affected organ. This tissue sample is then analyzed under a microscope to confirm the presence of cancer cells characteristic of hemangiosarcoma. A pathologist will evaluate the biopsy results and provide an accurate diagnosis.

While these diagnostic techniques help in identifying the presence of hemangiosarcoma, their limitations lie in the fact that there are no specific laboratory tests available for the disease. Therefore, a comprehensive evaluation of the clinical symptoms, imaging findings, and biopsy results is crucial in reaching a definitive diagnosis.
