Service led by Dr. Ji-won Park, DACVIM (Oncology) · Diplomate, American College of Veterinary Internal Medicine — Oncology Specialty
Veterinary oncology consultations are about goals of care first and treatment menus second. The first appointment with Dr. Park is sixty minutes — long enough to review the diagnosis, walk through the staging workup, talk honestly about prognosis, and let a family decide what kind of outcome they are working toward before any chemotherapy protocol is drawn up.
Some families come in ready to pursue every available treatment. Some come in knowing they want to focus on quality of life and time. Both are correct answers to the question. Our job is to make sure the answer is informed.
Ji-won completed his oncology residency at the Animal Medical Center in Manhattan and joined Field & Stone in 2023 to formalize the oncology service. He has personally administered roughly 4,000 chemotherapy doses since residency and reads every staging study before recommending a protocol.
What we do
- Consultation
- 60-minute first appointment to review diagnosis, prognosis, and treatment options. Honest framing of cure-vs-quality-of-life expectations.
- Staging workup
- Imaging (CT or ultrasound depending on tumor type), bloodwork, urinalysis, fine-needle aspiration, biopsy coordination, lymph node mapping.
- Chemotherapy protocol design
- Tumor-specific protocols. Lymphoma CHOP. Mast cell tumor vinblastine/prednisone. Hemangiosarcoma doxorubicin. Carboplatin protocols for osteosarcoma after amputation or limb-sparing. Metronomic protocols for selected slow-growing disease.
- Palliative care coordination
- Pain management, appetite support, nausea management, anxiolytics. Integrated with the general practice service for ongoing care.
- End-of-life conversations
- Quality-of-life assessment tools, hospice-style management, euthanasia coordination when the family decides it is time.
What we don't do
We do not perform radiation oncology. We do not have a linear accelerator and we are not going to install one. For radiation therapy we coordinate referrals to UC Davis Veterinary Medical Center in Davis or to the radiation oncology service at California Veterinary Specialists in Murrieta. The referring radiation oncologist receives our complete staging workup, the chemotherapy schedule, and a direct phone line to Dr. Park for protocol coordination.
We do not perform surgical oncology in-house in the sense of major resections — those go to Dr. Whitaker on the surgery service. Dr. Park coordinates pre-op imaging, staging, and post-op chemotherapy decisions in collaboration with the surgical team.
"An oncology consult is not really about which drug to give. It is about deciding, together, what we are trying to accomplish."
