Histiocystic sarcoma in dogs is fairly uncommon in most breeds, but there are certain dogs (such as golden retrievers, rottweilers, and Bernese mountain dogs) are more likely to develop the disease.
Localized Histiocystic Sarcoma
- It can also occur in internal organs such as the spleen and the heart.
- Localized histiocystic sarcoma will usually be detectable as a lump or mass under the pet’s skin.
- The dog will become lethargic.
- It will exhibit appetite loss and a drop in body weight.
- The dog will be unable to tolerate exercise and will tire easily.
- Early diagnosis can increase the pet’s chance of survival.
- Aggressive surgical procedures are usually recommended to remove localized tumors.
- Radiation therapy is used for killing cancer cells at the surgical site.
Disseminated Histiocystic Sarcoma
- Disseminated histiocystic sarcoma usually occurs in the lymph nodes, lungs, bone marrow, liver, and spleen.
- Disseminated histiocystic sarcoma is usually more fatal for the dogs.
- Symptoms will manifest depending on the affected internal organ.
- The dog may be anemic or will present other blood-related disorders.
- Chemotherapy can be administered to treat dogs with disseminated histiocystic sarcoma, although prognosis is usually poor because of delayed disease detection.
Histiocystic Sarcoma in Dogs Prognosis
- No definitive conclusion is established regarding the survivability rate of dogs that underwent treatment (either through surgery, chemotherapy, radiation therapy, or a combination of any of these) for localized histiocystic sarcoma.
- Prognosis is poor for dogs that have histiocystic sarcoma in the internal organs.
