Sep 18, 2023 · Soft tissue sarcomas (STS) arise from the neoplastic transformation of mesenchymal cells and comprise around 15 percent of all skin and subcutaneous tumours in dogs (Theilen and Madewell, 1979). They can arise in muscle, adipose, neurovascular, fascial and fibrous tissues but most commonly involve the skin and subcutis.

This type of cancer begins in either the bone or in the body’s soft tissues. The word sarcoma is derived from a Greek word and means “fleshy growth”. Sarcomas are a broad category of tumors classified together because of their similarities in their behavior and outcome. Sometimes further classification is made between bone sarcoma and soft tissue s...
The cause of canine sarcoma is not understood, and therefore, there is no natural way to protect against it. As with all cancers in dogs, early detection is critical.
Initially, there may be no symptoms related to the tumor. The tumor may grow very slowly over months or even years. A wide range of symptoms may present when a dog has one of the types of sarcoma. These may include: 1. Enlarged lymph nodes 2. Bloated stomach 3. Pale gums or bad breath 4. Difficulty eating or swallowing 5. Lethargy 6. Issues in the ...
Sarcoma in dogs is classified by various sub-types depending on the location of the cells from which they originate. 1. Osteosarcoma – primary bone tumor – usually arises in the bones of the limbs 2. Hemangiosarcoma (HSA) arises from endothelial cells 3. Fibrosarcoma – in fibrous connective tissue 4. Hemangiopericytoma – arises from pericyte cells ...
The most accurate diagnosis for sarcoma cancer in dogs is through surgical biopsy. However, fine-needle aspiration, taking a small needle and removing a sample of cells directly from the tumor for examination can produce quicker results and is less invasive. Other tests, namely bloodwork, urinalysis, lung x-rays, or ultrasound, may be recommended t...
The most commonly recommended treatment for soft tissue sarcomas is surgical excision with wide margins. These tumors often have “tentacles” extending beyond the tumor, and these must also be removed. Chemotherapy is not usually advised as a primary treatment unless surgery or radiation is impossible due to tumor size or location.
The predicted outcome or life expectancy for dogs with soft tissue sarcomas is highly variable. As described, sarcoma covers a wide range of tumors. Therefore, the prognosis depends on the type of sarcoma, its stage, size, and as in most cancers, the timing of detection. There may be a positive outcome for many soft tissue sarcomas if the mass can ...

How do you know if your pet has a soft tissue sarcoma?
Soft tissue sarcomas typically grow under the skin. They can feel soft or firm and are usually attached to underlying structures. While the tumor may feel well defined, they are highly invasive and send microscopic extensions in all directions. The extent of the tumor is poorly estimated by feel.
Soft tissue sarcomas are a broad category of tumors including those that arise from the connective, muscle, or nervous tissues in dogs and cats. These tumors are the result of abnormal production of these cell types in an uncontrolled manner.
What is a soft tissue sarcoma? Soft tissue sarcomas are a group of malignant cancers that arise from the skin and subcutaneous connective tissues, such as fat, muscle, cartilage, fibrous connective tissue, nerves and the “pericytes” of small blood vessels in the subcutis.
Mar 19, 2018 · Soft tissue sarcomas (STS) are a large group of tumours derived from mesenchymal tissues. STS may arise anywhere in the body, but most commonly appear on the appendicular skeleton. They typically present as a firm, discrete and expansile mass.
Soft tissue sarcoma can occur almost anywhere because soft and connective tissues are found throughout the body. However, it most commonly occurs in the skin and layers of tissue just below the skin. They make up 8 to 15% of all tumors in dogs that occur in these areas, and most grow slowly.
