RADIOTHERAPY AND CHEMOTHERAPY FOR DOMESTIC ANIMALS. I. THE TREATMENT OF MALIGNANT TUMOURS AND BENIGN CONDITIONS IN HORSES.

The research article focuses on exploring the radiation techniques used in human cancer therapy for the treatment of tumours and proliferative conditions in horses. The paper identifies the challenge of recurring tumours after surgical procedures and the need for radiotherapy in horses.

Overview of the Research

• The research focuses on the application of radiotherapy techniques, previously only used in humans, in the treatment of various conditions in horses.
• These conditions include equine sarcoids (a skin tumour in horses), carcinoma of the eyelids, malignant melanomas, and chronic ulcers, among others.
• The study contrasts the conventional surgical treatment with radiotherapy, outlining the high recurrence rate of tumours through surgical means.

Treatment Challenges

• The researchers identify two primary obstacles in applying radiotherapy to horses. The first is the large size of these animals, which are difficult to accommodate with conventional radiotherapy machines.
• However, this issue can potentially be overcome by the use of radium needles and radon seeds, which provide a more convenient and practical form of therapy for larger subjects.

Research Gaps and Possible Risks

• The second challenge noted is the significant knowledge gap about the reaction of horses to ionising radiation. This is of interest because horses have a unique biological structure, specially adapted for locomotion, with specific reactions to radiation on their tendons and bones. It’s a core focus of this research to ascertain the impact of radiation.
• The risks associated with subjecting horses to radiation treatment remains a critical concern throughout the research. Ensuring that the potential benefits outweigh the risks is a crucial balancing act in the exploration of these cancer therapies for horses.
