How Long Can A Dog Survive With Hemangiosarcoma After Surgery?

Have there been documented cases of dogs successfully surviving hemangiosarcoma? In one such case, a 6.5-year-old dog was diagnosed with splenic hemangiosarcoma. The treatment approach in this instance involved administering micronized fenofibrate orally once a day following splenectomy. Remarkably, the dog not only survived but thrived for a period exceeding 26 months (equivalent to 804 days) after the initial diagnosis, with no apparent adverse effects resulting from the fenofibrate treatment. This remarkable case highlights the potential of fenofibrate as a treatment option for hemangiosarcoma in dogs, offering hope to both veterinarians and pet owners grappling with this challenging condition.

When it comes to dogs diagnosed with tumors, the outcome can vary depending on several factors, including the type of tumor and its stage. Generally, the surgical removal of low-grade tumors can be highly effective and often results in a complete cure for the dog, eliminating the cancer entirely. However, the prognosis is not as favorable when the tumor is of a high-grade malignancy or has spread to the lymph nodes. In such cases, life expectancy after diagnosis and treatment tends to be more limited, typically ranging from six to twelve months. This information is important for dog owners to consider when making decisions about their pet’s healthcare. As of February 7, 2023, these are the general guidelines for understanding the potential outcomes of tumor removal in dogs.

What is the typical lifespan of a dog after undergoing a spleen removal procedure? To shed light on this topic, it’s important to consider the available data. According to one study (reference 8), dogs who underwent splenectomy alone had a reported median survival time of 86 days, and only 6.25% of them survived for a year. However, a more recent study (reference 3) provides slightly different figures, with a median survival time of 1.6 months, 11.1% still alive after one year, and 4% still alive after two years following the spleen removal procedure. These statistics give us a broader understanding of the expected outcomes for dogs after spleen removal surgery.
