What is soft tissue sarcoma?
Soft tissue sarcomas are tumors of connective tissues. Different soft tissue sarcomas are grouped together within this larger category because they have similar appearances on biopsy and similar clinical behavior in the patient. Subtypes include fibrosarcoma, hemangiopericytoma, liposarcoma, myxosarcoma, and undifferentiated sarcoma, among others.

Other Therapies. Electrochemotherapy – This form of treatment can be used as an alternative to definitive radiation therapy. Protocols vary, but all patients are anesthetized or heavily sedated before treatment. Chemotherapy is injected into the tumor site and usually also given intravenously.
What is the treatment for a tumor?
Electrochemotherapy – This form of treatment can be used as an alternative to definitive radiation therapy. Protocols vary, but all patients are anesthetized or heavily sedated before treatment. Chemotherapy is injected into the tumor site and usually also given intravenously. A brief electrical pulse is applied in a systematic manner over the tumor site. Treatments are repeated weekly for an average of 3 sessions.

How to tell if a dog has a sarcoma?
Signs related to soft tissue sarcomas include the following: 1 Pets that have tumors arising from muscle tissue may show signs of pain in the affected region and may have a distinct firm and growing mass (tumor). 2 Tumors that are located on the limbs may cause changes in your pets’ ability to walk and the limbs may have obvious swelling. 3 Pets that have tumors arising from nervous tissue may be unable to use the affected limb or may show other neurological signs. 4 Pets with intestinal tumors may have signs of an intestinal blockage such as vomiting, diarrhea, lack of appetite, weight loss, and abdominal pain. 5 Pets with soft tissue sarcomas in the mouth often have bad breath (halitosis), difficulty eating, loss of appetite, bleeding in the mouth, or obvious tumors in the mouth. 6 Signs of a soft tissue sarcoma affecting the reproductive system depend on the location of the tumor. For example, if the prostate is affected, difficult urinating or defecating may be noted.

Radiation can affect wound healing, so it may not be started until a month or so after surgery. Radiation may also be used before surgery to shrink the tumor and make it easier to remove. This is called neoadjuvant treatment.
Can radiation be used to shrink a tumor?
Radiation may also be used before surgery to shrink the tumor and make it easier to remove. This is called neoadjuvant treatment. Radiation can be the main treatment for sarcoma in someone who isn't healthy enough to have surgery. Radiation therapy can also be used to help ease symptoms of sarcoma when it has spread.
Is proton beam therapy available?
Proton beam therapy is not widely available. Intraoperative radiation therapy (IORT): For this treatment, one large dose of radiation is given in the operating room after the tumor is removed but before the wound is closed.
What is intraoperative radiation therapy?
Intraoperative radiation therapy (IORT): For this treatment, one large dose of radiation is given in the operating room after the tumor is removed but before the wound is closed.

What Causes Soft Tissue Sarcoma in Dogs?
- Unfortunately, much like other types of cancer, soft tissue sarcomas do not have a particular cause, and as such, they can’t be prevented effectively by pet parents. They are somewhat more common in middle-aged to old dogs, and they have been found to affect larger breeds to a higher extent compared to others.
Symptoms
- The location of the tumor is what determines the clinical signs. As we have noted in the beginning, this type of tumor can occur pretty much anywhere in the body where there is conjunctive tissue, for example, so masses can develop on the body surface or inside various organs (from the kidneys to the heart). They are known to grow slowly, so the symptoms become more severe as …
Diagnosis
- Microscopic examination using a tissue sample (such as one extracted via biopsy) can assist the vet in making a definitive diagnosis of a soft tissue sarcoma. X-rays, an MRI, or a CT scan can be useful, as well, especially when it comes to determining the nature of the tumor and its extent, which can be extremely helpful for the medical professional when it comes to choosing the corr…
Treatment
- In general, cancer can be treatedusing one or several types of treatments, but there are mainly three kinds available depending on the tumor type — surgery, chemotherapy, and radiation therapy. Surgical excision must be deep, as well as wide, so as to remove all of the tumor tissue. If the surgical treatment was performed correctly and all of the margins of the cancerwere remove…
Life Expectancy
- The pet’s life expectancy largely depends on the location and nature of the tumor, as well as the exact time it was diagnosed. However, it is generally considered that dogs that receive surgical treatment will live for approximately four years following the operation while those that undergo both surgery and radiation therapy can live up to six yea...
Prognosis
- Dogs that have already developed metastases by the time they are diagnosed have a poor prognosis, and so do those that have sarcomas in their abdomen, no matter the organ that was affected. Generally, most such tumors have a high likelihood of being metastatic. The pets that have sarcomas in their mouth can also get a poor prognosisgiven the difficulty to treat the tumo…
