Summary
Radiation therapy (RT) for canine osteosarcoma (OSA) offers palliative pain relief or limb-sparing options. Curative-intent RT, especially stereotactic radiosurgery, shows promise when combined with chemotherapy and careful patient selection for better outcomes.
Area of Science:
- Veterinary Oncology
- Radiation Oncology
Background:
- Canine appendicular osteosarcoma (OSA) management involves palliative or curative intent radiation therapy (RT).
- Palliative RT aims to alleviate pain and lameness with minimal side effects.
- Standard curative care includes limb amputation and chemotherapy; RT is an alternative for limb sparing.
Purpose of the Study:
- To review the efficacy and application of radiation therapy in managing canine appendicular osteosarcoma.
- To differentiate between palliative and curative intent RT strategies.
- To highlight advanced RT techniques for improved local disease control.
Main Methods:
- Review of palliative RT approaches (coarse fractionation, radiopharmaceuticals).
- Evaluation of curative-intent RT, including limb-sparing protocols.
- Discussion of advanced techniques like stereotactic radiosurgery and intra-operative irradiation.
Main Results:
- Palliative RT effectively manages pain and lameness with few acute adverse effects.
- Fractionated curative-intent RT is often ineffective for local control.
- Advanced RT techniques combined with chemotherapy and case selection improve local disease control.
Conclusions:
- Radiation therapy can be tailored for palliative or curative intent in canine OSA.
- Advanced RT techniques offer improved outcomes for limb-sparing management.
- Appropriate planning and administration of RT result in manageable adverse effects.
