«Prior to this, the longest reported median survival time
of dogs with hemangiosarcoma of the spleen that underwent no further treatment was 86 days.
Palliative surgery is frequently performed in dogs with osteosarcoma (bone cancer) by amputating a limb, or a spleen removed
in dogs with hemangiosarcoma in order to prevent internal bleeding.
This mushroom is also undergoing investigation in veterinary patients,
specifically dogs with hemangiosarcoma, because it contains a protein - bound complex sugar which appears to have anti-cancer properties.
Compared to dogs with non-hemangiosarcoma malignancy, small and
large dogs with hemangiosarcoma were 8 and 4 times more likely, respectively, to have thrombocytopenia.
Dog Studies CANCER Novel Therapies Common heart medications as an effective adjunct therapy
for dogs with hemangiosarcoma, an aggressive and deadly cancer.
Morris Animal Foundation - funded researchers at the University of Minnesota felt that by gaining a better understanding of the underlying biology of this aggressive tumor, they could discover new ways of improving long term prognosis
in dogs with hemangiosarcoma.
Researchers at the University of Pennsylvania School of Veterinary Medicine treated dogs with a commercially available Coriolus versicolor product and found the longest reported survival time for
dogs with hemangiosarcoma.
Dogs with hemangiosarcoma were 8 (small dogs) to 9 (large dogs) times more likely to develop hemoabdomen, compared to dogs with other cancers.
Hemoabdomen was reported in 56 % of
all dogs with hemangiosarcoma.
Among the malignant splenic cases, the percentage of
dogs with hemangiosarcoma was also higher for large dogs (65 %) than small dogs (46 %)(the picture shows splenic hemangiosarcoma in a Skipperke).
The next research step is to further investigate propranolol and other beta blockers to see if they will work in combination with chemotherapy drugs, and then move to testing this new treatment approach in
dogs with hemangiosarcoma.
Despite considerable efforts by veterinarians and scientists to find effective treatments, the outcome for
dogs with hemangiosarcoma has changed very little over the past few decades.
Despite considerable efforts to find effective treatments, the outcome for
dogs with hemangiosarcoma has changed very little over the past 30 years.
For European owners of
dogs with hemangiosarcoma or lymphoma, please consider submitting samples to the Animal Health Trust (see below).
Plasma vascular endothelial growth factor (VEGF) concentrations in healthy dogs and
dogs with hemangiosarcoma.
Dogs with hemangiosarcoma of the skin may have bruising associated with a skin tumor.
Due to the highly malignant nature and advanced state of disease (often to other organs), the prognosis for
dogs with hemangiosarcoma is quite guarded.
Researchers will determine if common heart medications are an effective adjunct therapy for
dogs with hemangiosarcoma.
