• Clinical Trial for Evaluation of Propranolol and Doxorubicin in the Treatment of Canine Hemangiosarcoma

    Canine hemangiosarcoma is a largely incurable cancer in dogs, and treatment approaches to improve outcomes have remained relatively stagnant over the past few decades. Treatment remains a challenge partly because the cancer is frequently detected at an advanced stage and because these tumors are often resistant to chemotherapies. Recently published

  • Prevalence of Bartonella spp. Infection in Dogs with Cardiac and Splenic Hemangiosarcomas within and between Geographic Locations

    Splenic masses comprise ~50% of all canine splenic disease. Despite advances in imaging and pathologic definition, the etiology and medical relevance of splenic lesions in dogs are often ambiguous. While some splenic tumors are benign, approximately two-thirds are highly malignant and carry a poor prognosis. Hemangiosarcoma (HSA) accounts for the

  • Disease Risks Associated with Spay and Neuter: A Breed-Specific, Gender Specific

    This study extends the investigator’s recently completed AKC Canine Health Foundation-funded project studying 12 dog breeds to identify major differences in the degree to which spay or neuter may be related to an increase in joint disorders (hip dysplasia; cranial cruciate ligament tear) and/or cancers (lymphoma; hemangiosarcoma; and mast cell

  • A Novel Approach for Prevention of Canine Hemangiosarcoma

    Hemangiosarcoma, an aggressive form of cancer in dogs, is the cause of death for one out of every five Golden Retrievers in the United States. Portuguese Water Dogs and Boxers also have an especially high risk for this disease which is devastating for all dogs. Hemangiosarcoma is incurable partly because

  • Health Implications of Early Spay/Neuter on Canine Health

    Most dogs in the United States are spayed or neutered, and the default recommendation has been to perform these elective surgeries prior to physical maturity. However, recent data suggest that early spay and neuter may adversely impact the health and well-being of dogs. In preliminary studies funded by CHF, Dr.

  • Innovations in Prevention, Diagnosis, and Treatment of Cancer

    Lymphoma and hemangiosarcoma are major health problems in Portuguese Water Dogs. This study collaborates with several top universities and researchers who are utilizing cutting edge technology to identify several regions of the genome that contain genetic, heritable, risk factors for lymphoma and hemangiosarcoma in Golden Retrievers. This information can then

  • Testing Strategies to Treat Drug-Resistant Hemangiosarcomas

    Lysosomal Drug Sequestration by CSF-1R (High) Tumor Cells Contributes to Drug Resistance in Canine Hemangiosarcoma Summary: Investigators are assessing the potential for a specific tumor-cell population in canine hemangiosarcoma to sequester drugs within their lysosomes as a novel mechanism of drug resistance. Description: Canine hemangiosarcoma is a common and highly

  • Disrupting the Differentiation of Cancer Stem Cells to Prevent the Spread of Hemangiosarcoma

    Hemangiosarcoma is a rapidly fatal disease. The lifetime risk is alarmingly high for some breeds like Golden Retrievers (~20% will die of this disease) and Portuguese Water Dogs (~15% will die of this disease). The risk of hemangiosarcoma is not limited to just these breeds but is considered a research

  • Assessing How a Protein Helps Hemangiosarcoma Cells Survive

    Canine hemangiosarcoma is a common and highly fatal cancer in dogs. Recent evidence suggests that populations of cancer stem cells give rise to tumors, promote tumor growth and are the main culprits behind drug resistance and disease recurrence. This study examines how a protein expressed by stem cells contributes to

  • Searching for Ways to Control Hemangiosarcoma Cancer Cells in Dogs

    Hemangiosarcoma is a highly metastatic and incurable cancer that can affect dogs at any age. It is particularly prevalent in certain breeds such as Golden Retrievers, German Shepherds and Portuguese Water Dogs. Unfortunately, hemangiosarcoma is a disease that is poorly understood and for which there are currently no good treatment
