Palliative-intent radiation therapy (RT) is the most consistent and durable non-surgical option for cancer-related pain in dogs and cats when disease-specific treatment is not feasible, reducing pain significantly in 70–90% of patients with cancer-related pain, with response durations ranging from a few months to more than a year depending on tumor type.AAHA Clinical G…
Multimodal pain management is the standard of care for oncology patients. Pain may originate from the tumor itself (e.g., osteosarcoma), from treatment modalities such as RT or chemotherapy, or from concurrent disease such as osteoarthritis, and each source warrants targeted management.AAHA Clinical G… Two monoclonal antibody therapies targeting nerve growth factor are available: bedinvetmab for dogs and frunevetmab for cats.AAHA Clinical G… Injectable buprenorphine controls pain for 24 hours in feline patients, while buprenorphine transdermal solution provides 4 days of pain control.AAHA Clinical G… Gabapentin and pregabalin have mixed effectiveness as adjunctive pain management in dogs and cats, including in chemotherapy patients.AAHA Clinical G… Intravenous bisphosphonates reduce bone pain.AAHA Clinical G…
Palliative care should be initiated early in the course of disease, not reserved for the terminal phase — human data indicate that early initiation increases both quality and quantity of life.AAHA Clinical G… The initial palliative appointment may extend up to 3 hours and should include a complete physical examination with pain assessment, a thorough discussion of diagnosis and prognosis, and development of a goals-of-care plan tailored to the client.AAHA Clinical G…
Hospice represents the end stage of palliative care and adds services for later-stage, terminally ill patients: planning for disease-specific decline, crisis management, and a defined plan for death — whether by euthanasia or palliated natural death.AAHA Clinical G… For cats specifically, establishing a "budget of care" and integrating the caregiver as an active member of the care unit are foundational to the hospice consultation.Journal of Feli… Compromised physical health, including uncontrolled pain or illness, directly impairs emotional health and must be addressed as part of whole-patient quality of life.Journal of Feli…
A daily care plan and a crisis plan should be developed at the outset of palliative or hospice enrollment, including explicit discussion of clinical signs of approaching and imminent death.AAHA Clinical G… If palliated natural death is chosen over euthanasia, palliative sedation should be discussed in advance.AAHA Clinical G…
