The first privately-owned veterinary cancer hospital in the country with a research facility, Veterinary Oncology Services and Research Center (VOSRC) was created to make sure its patients receive the most advanced, leading-edge pet cancer treatments. We provide consultations as well as personalized recommendations and treatment for all types of pet cancer.

Established in 1990 by Dr. K. Ann Jeglum, V.M.D., a Charter Member of the American College of Veterinary Internal Medicine, VOSRC is a progressive and dynamic organization that is committed to the well-being of its patients and the peace of mind of its clients. Our facility, Veterinary Oncology Services and Research Center in West Chester, Pennsylvania offers full oncological care for your pets in the Mid-Atlantic and Philadelphia, PA area.

Lesley’s Place Logo We also support and partner with Lesley's Place, an independent non-profit program dedicated to research and treating homeless dogs with mammary cancer.

VOSRC is partnering with ELIAS Animal Health to conduct a clinical trial to evaluate ELIAS Cancer Immunotherapy, ELIAS’s vaccine-enhanced adoptive T-cell therapy, following chemotherapy as treatment for B-cell lymphoma in dogs.

If your dog has been recently diagnosed with lymphoma, please call the office to see if you are eligible to participate. We are currently accepting new B-cell canine lymphoma patients into the study.

We are pleased to learn from ELIAS Animal Health that the USDA agrees ECI demonstrates reasonable expectation of efficacy for treating bone cancer in dogs. VOSRC was a participant in the clinical trial that led to the commercialization and licensing approval. We currently offer the ELIAS ECI treatment to canine osteosarcoma patients commercially at our facility.

New Treatment Option: Immunotherapy with Elias
