stage 1 hemangiosarcoma in dogs

those studies included dogs with different clinical stages of disease. A dog with hemangiosarcoma is euthanized only when they have no chances of survival. Cancer of the blood vessel walls, called hemangiosarcoma, is most often seen in German Shepherds, Golden Retrievers, Flat-Coated Retrievers, and Boxers. However, over fairly large numbers of treated animals published, the following statistics are offered as guides: HSA Patients in TherapyThe quality of life for patients being treated for HSA is generally good to excellent. Hemangiosarcoma (HSA) is an aggressive, malignant cancer of the blood vessels that often grows as a mass in the spleen, liver, or heart, but can also be found in other parts in the body. Vincristine (intravenous administration) 3. Then in a day or two, the blood goes back into the circulation causing the dog to feel better. Canine Lymphoma and Hemangiosarcoma Lymphoma and hemangiosarcoma are incurable. Hemangiosarcoma is cancer of the vascular endothelium, or the blood vessel walls. Stage III: Tumor with muscle involvement. Emergency intervention (surgery and supportive care) is critical to patient survival. If internal organs are involved, the patient may be weak/collapsing, have pale gums, a rapid and shallow respiratory rate and perhaps abdominal enlargement. When to euthanize a dog with hemangiosarcoma? Hemangiosarcoma is one of the most malignant forms of cancer in dogs. Hemangiosarcoma in dogs is a cancer of the blood vessels that can occur either on the surface of the skin or inside of the body itself. The median survival time of the dogs with stage I disease was 151 days; of the dogs with stage II disease, 107 days; and of the dogs with stage III disease, 73 days. Those affecting the bone exhibit signs of bone pain associated with radiographic bone lesions. Sonographic examination was found superior in diagnosing splenic neoplasia when compared to radiography. Dogs must have adequate organ function as indicated by standard laboratory tests 6. This kind of cell lies in the blood vessels and the consequences of the aggressive development of metastases. For those undergoing surgery plus chemotherapy, the one year survival rate is 20%. In stage II and II, half of the patients were presented in shock or collapse after an acute rupture of the tumor. In most cases, tissue biopsy is needed to definitively diagnose hemangiosarcoma, as other benign and malignant causes can cause similar abnormalities. Canine hemangiosarcoma (HSA), a malignant tumor of blood vessel endothelial cells, is a relatively common malignancy in dogs compared with other species. Survival times are often dependent on location as well as ability to surgically excise the mass. Echocardiogram can interrogate the right atrium/auricle for signs of heart base masses as well as evaluate for pericardial effusion and evidence of ventricular disease that may be related to systemic disease. It accounts for 0.2 to 3 percent of all canine tumors with a mean age at diagnosis of 9 to12 years. Teatment of HSAHemangiosarcomas are, unfortunately, highly aggressive tumors and virtually all patients will eventually die from the disease. Hemangiosarcoma is relatively common in dogs; it is estimated that this type of cancer accounts for 5-7% of all tumors seen in dogs. Hemangiosarcoma of the spleen is the most common cancer of the spleen in dogs. However, dogs' hemangiosarcoma doesn’t usually come to life in just any organ. Patient EvaluationThe first step in treating veterinary patients for HSA is to evaluate general patient health and to assess the extent of the cancer (clinical staging.) Animals usually present to their veterinarian for sudden collapse due to internal bleeding from the mass. One thing I believe heightens this feeling of pain among dogs is the fact that they do not know what may be causing this pain. However, a systemic thrapeutic approach which involves, 1) surgical resection of the primary tumor and 2) the addition of chemotherapy, can provide a remission from the cancer. This step helps the clinician formulate a treatment plan and allows more precise determination of the prognosis. Dogs must weigh at least 10 kg 5. With respect to immunotherapy, the potential benefit for L-MTP-PE in addition to chemotherapy is still not clear. This cancer is typically encountered in older, large breed dogs with potential predispositions noted in males and in certain breeds (German Shepherds, Golden Retrievers and Labrador Retrievers). Staging of HSAThe prognosis for dogs with HSA is known to be affected by the clinical stage of the disease. 4. In general, this refers to: Stage I: Localized tumor; no other tumors seen at the time of surgery Stage II: A ruptured tumor which is confined to the primary site, such as an HSA of the heart or spleen. Prognosis An exact prognosis for a particular patient with HSA is impossible to predict. Stage II (T1-2N0-1M0): Tumor <5 cm or greater than or equal to 5 cm in diameter, that is either confined to the primary site, ruptured (hemoabdomen/pericardial effusion), or invading subcutaneous tissue with evidence of regional lymph node involvement, with evidence of distant disease spread. This type of tumor, known as a hemangiosarcoma, is unique to dogs and most common in German Shepherd Dogs and Golden Retrievers. Without surgery, a dog with hemangiosarcoma would only live for between one (1) week or two (2) weeks, tops, unfortunately. It is a cancer of the cells that line the endothelial cells (blood vessels), and therefore can be found in any part of the body. Of course, some might live longer out of pure chance. These tumors can arise anywhere in the body but most frequently involve the spleen, heart, liver and skin. This boogeyman is … The most common primary site for hemangiosarcoma is the spleen, accounting for ¼ to ½ of the splenic tumors that arise in dogs. This is known as splenic hemangiosarcoma. But considering that with surgery, a dog with hemangiosarcoma would be looking at about six (6) months of extra time, without surgery can’t be that long. The chemotherapy drugs are given as to minimize toxicity to the patient while still damaging the malignant cells. Cyclophosphamide or Lomustine (oral administration) 4. At this point, emergent intervention (ie surgery, pericardiocentesis) is indicated to control the bleeding, address the associated clinical signs related to blood loss, remove infiltrated masses or organs, and to obtain a definitive diagnosis. Doxorubicin (intravenous administration) 2. Most often, treatment is continued for at least 6 months. If you have an old dog and you get to see the symptoms then this won’t be a surprise because around 8 out of 10 senior dogs get along this disease. About 25% of dogs with HSA have both the spleen and heart involved.
