Histiocytic sarcoma is a rare cancer that can affect dogs. It is an aggressive cancer and is often hard to diagnose and treat. As one of the most serious types of cancer affecting dogs, it is important for pet owners to understand the prognosis and management of this condition. In this blog post, we will discuss how long a dog can live with histiocytic sarcoma and the various treatment options available. We will also look at the symptoms and risk factors associated with this condition to help owners decide on the best course of action for their pet. Understanding the prognosis and potential treatment options of histiocytic sarcoma can help pet owners make the most informed decision when it comes to their pet’s health.

Even with multi-modal treatment, affected dogs have a poor prognosis with a median survival time of less than six months. To improve outcomes for dogs affected by HM, the AKC Canine Health Foundation (CHF) and its donors are committed. CHF-funded researchers are making fascinating discoveries thanks to recent advancements in genetic technology that may enhance the diagnostic and treatment options for this aggressive cancer. Fever, weight loss, inappetence, lethargy, and possibly a visible mass are some of the non-specific clinical signs of HM. These signs can also be present in cases of other prevalent cancers, like lymphoma and hemangiosarcoma. In order to increase a dog’s chances for a successful recovery, an accurate diagnosis must be made as soon as possible. This is because the treatment options and prognoses for these cancers are very different. Researchers at North Carolina State University investigated the genetic features of canine HM using funding from CHF Grant 01557: Narrowing the Search for the Genetic Basis of Histiocytic Malignancies. Their findings, which were just published in Chromosome Research2, demonstrate that HM is a complex illness with changes to the entire genome, including:
The fact that the copy number alterations mentioned above were specific to HM and could accurately distinguish it from lymphoma and hemangiosarcoma is a promising finding from this study. Researchers will keep looking into these distinct genetic traits to develop a quick and precise HM diagnostic test. Researchers at the University of Rennes in France will use funding from CHF grant 02446: Development of Genetic Biomarkers to Improve Diagnosis and Treatment of Canine Histiocytic Sarcoma to support this work as they create a blood test to precisely diagnose HM and examine whether earlier diagnosis and targeted treatment selection actually improve the prognosis for affected dogs.
Enroll in a clinical trial or donate samples to help with research on canine health. Dogs in both the healthy and diseased states must provide samples.
The aggressive cancer known as histiocytic malignancies (HM), also known as histiocytic sarcoma or malignant histiocytosis, is most frequently found in Bernese Mountain Dogs (BMD) and Flat-Coated Retrievers (FCR). Additionally, Rottweilers, Labrador Retrievers, Golden Retrievers, and other breeds, including mixed breeds, exhibit HM. HM is devastating for these more frequently affected breeds, accounting for up to 60% of splenic tumors in Flat-Coated Retrievers and up to 64% of all malignancies in the BMD, despite being rare in the general dog population.
Hopefully, a better understanding of how and why this cancer is so aggressive will lead to more precise diagnostic procedures and effective, targeted treatments. This study will have an effect on the health of all canines affected by cancer as part of CHF’s extensive portfolio of canine cancer research.
FAQ
How long will my dog live with sarcoma?
Low grade soft tissue sarcomas have a very good outlook, particularly if surgically removed completely. Survival times are 2-4 years with low grade tumors. Even with aggressive treatment, high grade tumors have a shorter survival time (typically less than one year).
How rare is histiocytic sarcoma in dogs?
Less than 1% of all lymphoreticular neoplasms (blood-lymphatic cell population) in dogs are canine histiocytic sarcomas, making them a rare tumor.
How fast do dog sarcomas grow?
As the tumor spreads, it may become painful or make it difficult to walk. Over the course of a few weeks, they could expand quickly. More commonly they grow slowly over months or years. In severe cases, the skin next to the tumor may ulcerate or become infected.
What are the final stages of cancer in dogs?
Recognize your dog’s symptoms of pain, discomfort, and distress. Labored breathing: Difficulty catching their breath; short, shallow breaths; or wide, deep breaths that appear to be labored breaths. These symptoms are frequently dramatic and can be an obvious indicator that euthanasia should be considered. Lack of appetite, lethargy.
