Cancer Immunotherapy for the Veterinary Patient

The ability of the immune system to protect against tumor development and to attack malignant cells once they arise has been recognized for more than 50 years. Since this time, our understanding of the complex relation between the immune system and the development of cancer has increased dramatically, largely because of improvements in the tools used to study tumor immunology at the molecular level. These advances are leading to the development of increasingly sophisticated and effective immunotherapeutics for human and veterinary oncology patients; indeed, some forms of immunotherapy already have a place alongside more conventional treatment modalities, such as surgery, radiation therapy, and chemotherapy.
