Understanding Canine Spleen Cancer
When it comes to canine health conditions, spleen cancer is a significant concern for dog owners. Spleen cancer, also known as hemangiosarcoma, is a malignant tumor that affects the cells lining the blood vessels of the spleen. This type of cancer is more prevalent in dogs than in humans, and it is estimated that approximately two-thirds of masses in the spleen are malignant, with two-thirds of those being diagnosed as hemangiosarcomas AVIM.
Overview of Spleen Cancer
Canine spleen cancer is most frequently diagnosed in older dogs, typically beyond middle age. Certain breeds, such as German Shepherds, Labrador Retrievers, and Golden Retrievers, are more commonly affected by this condition AVIM. Canine hemangiosarcoma accounts for approximately 5-7% of all tumors seen in dogs and is estimated to affect 1.5 to 2.5 million of the approximately 72 million pet dogs in the United States AKC Canine Health Foundation.
The primary sites for canine spleen cancer are the spleen itself, the right atrium of the heart, and the subcutis AKC Canine Health Foundation. These tumors infiltrate the surrounding normal tissues and often metastasize, spreading to other parts of the body. The abnormal behavior of the tumor cells leads to the formation of malformed blood vessels, which can result in clotting and rupture of the tumor AKC Canine Health Foundation.
Common Breeds Affected
While any dog can develop spleen cancer, certain breeds are more predisposed to this condition. German Shepherds, Labrador Retrievers, and Golden Retrievers are among the most commonly affected breeds AVIM. Other breeds with higher risks include Portuguese Water Dogs, Bernese Mountain Dogs, Flat Coated Retrievers, Boxers, and Skye Terriers AKC Canine Health Foundation. In Golden Retrievers, the estimated lifetime risk of developing hemangiosarcoma is 1 in 5 AKC Canine Health Foundation.
While certain breeds may be more susceptible, it’s important to note that spleen cancer can occur in dogs of any breed or mixed breed. Regular veterinary check-ups and awareness of the symptoms can aid in early detection and prompt treatment.

Understanding the overview of spleen cancer and the breeds commonly affected is crucial for dog owners. In the following sections, we will explore the diagnosis, treatment options, prognosis, and ongoing research related to this condition.
Diagnosis and Treatment Options
When it comes to diagnosing and treating canine spleen cancer, prompt and accurate detection is essential. Understanding the diagnostic procedures and treatment options available can significantly impact a dog’s prognosis and quality of life. In this section, we will explore the diagnostic procedures used and the surgical intervention commonly employed in the management of this condition.
Diagnostic Procedures
Diagnosing canine spleen cancer often requires a combination of imaging techniques and surgical intervention. The primary diagnostic procedure for a suspected splenic mass is the surgical removal of the spleen, followed by a biopsy of the tissue to obtain a definitive diagnosis. This procedure allows veterinarians to assess the tumor’s characteristics, determine whether it is malignant, and plan appropriate treatment.
Surgical Intervention
Surgery plays a crucial role in the treatment of spleen cancer in dogs. It is the primary approach to address a splenic mass and obtain a definitive diagnosis. During the surgery, the veterinarian removes the affected spleen and submits the sample for biopsy. This allows for a more accurate assessment of the tumor type and severity.
It’s important to note that not all splenic masses are malignant, and surgical intervention can provide relief for benign conditions as well. However, for dogs diagnosed with splenic hemangiosarcoma, the prognosis is generally poor, with a median survival time of approximately 1-2 months with surgery alone (AVIM).
After surgery, additional treatment options may be recommended based on the specific case. For example, chemotherapy using drugs like doxorubicin (adriamycin) may be used to slow the progression of hemangiosarcoma in dogs. The addition of chemotherapy to the treatment plan can extend the median survival time to about 4-6 months (AVIM). However, it’s important to consider the potential side effects of chemotherapy, such as stomach upset, decreased white blood cell count, thinning of the fur coat, and cumulative toxicity on the heart.
It’s worth mentioning that ongoing research and developments in the field of canine spleen cancer aim to improve treatment outcomes. Early detection methods and targeted therapies, including stem cell research, are being explored to enhance the management of this condition. Staying informed about the latest advancements can help dog owners make informed decisions regarding the diagnosis and treatment of this challenging disease.
By understanding the diagnostic procedures and treatment options available, dog owners can work closely with their veterinarians to make informed decisions about the best course of action for their furry companions. Early detection, prompt surgical intervention, and appropriate follow-up care can help improve the overall prognosis and quality of life for dogs diagnosed with spleen cancer.
Prognosis and Survival Rates
Understanding the prognosis and survival rates associated with canine spleen cancer is crucial for dog owners seeking treatment options for their beloved pets. Let’s explore the survival rates after surgery and the impact of chemotherapy on this condition.
Survival Rates After Surgery
Surgery is the primary treatment for a splenic mass or spleen tumor, and it provides the best chance for long-term survival. However, it’s important to note that the prognosis can vary depending on the stage and type of cancer.
A retrospective analysis of 32 dogs with Stage I or II splenic hemangiosarcoma treated by splenectomy alone showed a median survival time of 86 days, with a mean of 116 days and a range of 14 to 470 days. The one-year survival rate was estimated to be 6.25%. The median survival time with surgery alone for a splenic mass is approximately 1-2 months, with patients succumbing to metastatic disease (AVIM).
It’s important to consult with a veterinarian to determine the stage and nature of the cancer and to discuss the potential outcomes and treatment options based on individual cases. Early detection and intervention can significantly improve the prognosis.
Impact of Chemotherapy
In addition to surgery, chemotherapy can play a vital role in the treatment of canine spleen cancer, especially for hemangiosarcoma. Patients treated with surgery and chemotherapy for hemangiosarcoma experience a median survival time of 4-6 months (AVIM).
The primary chemotherapy drug used for canine hemangiosarcoma is doxorubicin (adriamycin). It is typically administered intravenously once every 3 weeks for 4-6 treatments. Chemotherapy aims to target any remaining cancer cells and reduce the risk of metastasis. The specific treatment plan and duration may vary based on the individual dog’s condition and response to treatment.
Combining surgery with chemotherapy has shown an extension in median survival time compared to surgery alone. The addition of chemotherapy using available protocols can extend the median survival to about 180 days, compared to approximately 90 days with surgery alone.
It’s crucial to note that each dog is unique, and individual responses to treatment can vary. The veterinarian will consider the dog’s overall health, cancer stage, and other factors when determining the most appropriate treatment plan.
By understanding the survival rates after surgery and the impact of chemotherapy, dog owners can make informed decisions regarding the treatment options for their furry companions. Regular check-ups, close monitoring, and communication with the veterinarian are essential to ensure the best possible outcome for dogs diagnosed with spleen cancer.

Canine Hemangiosarcoma Facts
When it comes to spleen cancer in dogs, also known as canine hemangiosarcoma, understanding its prevalence, risk factors, and tumor characteristics is essential. Let’s explore these important facts about this type of cancer in dogs.
Prevalence and Risk Factors
Canine hemangiosarcoma accounts for approximately 5-7% of all tumors seen in dogs and is estimated to affect 1.5 to 2.5 million of the ~72 million pet dogs in the United States. It is more commonly diagnosed in older dogs, typically beyond middle age (older than 6 years) (AKC Canine Health Foundation).
Certain breeds are more predisposed to developing hemangiosarcoma. German Shepherds, Labrador Retrievers, and Golden Retrievers are among the most commonly affected breeds. However, other breeds like Portuguese Water Dogs, Bernese Mountain Dogs, Flat Coated Retrievers, Boxers, and Skye Terriers also have an increased risk (AKC Canine Health Foundation). It is important to note that approximately 2/3rds of masses in the spleen are malignant, and of those, 2/3rds are diagnosed as hemangiosarcomas (AVIM).
Tumor Characteristics
Canine hemangiosarcoma is an incurable tumor that arises from cells lining the blood vessels. It is more prevalent in dogs compared to humans, where a similar tumor called angiosarcoma is rare and associated with workplace exposure to certain chemicals. It is important to distinguish between hemangiosarcoma and benign tumors of vascular endothelial cells, called hemangiomas, which are not life-threatening.
The most common primary sites for canine hemangiosarcoma are the spleen, the right atrium of the heart, and the subcutis (under the skin). The tumor infiltrates normal tissues surrounding it and can also metastasize to other areas of the body. The tumor cells attempt to form blood vessels, but these vessels become malformed and prone to clotting. Ultimately, this can lead to rupture of the tumor.
