Equine Veterinarian Perspectives on Mucocutaneous Tumors in Horses: A Survey-Based Study in Portugal.

Abstract: This study explores equine veterinarians' clinical practices regarding mucocutaneous tumors, based on a survey conducted among members of the Portuguese Association of Equine Veterinarians, and examines their perceptions of owner and buyer concerns regarding these tumors. Veterinarians expressed significantly greater concern about squamous cell carcinoma (SCC) during routine examinations ( < 0.001) compared to sarcoids and melanomas. Concern over sarcoids was significantly greater during pre-purchase evaluations compared to routine clinical exams ( = 0.03). For melanomas, a trend toward increased concern in pre-purchase evaluations compared to routine examinations was observed ( = 0.07). There was a statistically significant association between the use of histopathology and the type of tumor ( < 0.001). Histopathology was performed less frequently in cases of melanoma compared to other tumor types. The cost was the main reason for not performing histopathology. During pre-purchase exams, buyers appeared to show greater concern regarding the presence of sarcoids ( = 0.001) and melanomas ( = 0.002) than regular owners. This study highlights the need to bolster training and education in equine oncology for veterinarians and owners to promote better diagnostic and therapeutic practices.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article explores how horse veterinarians in Portugal approach and perceive mucocutaneous tumors, specifically focusing on the types of tumors that cause the most concern during both routine examinations and pre-purchase evaluations. The study also looks into the relationship between tumor type and the use of histopathology.

Survey Results and Veterinarian Opinions

  • The survey was conducted among members of the Portuguese Association of Equine Veterinarians with the goal of understanding their clinical practices and perceptions regarding mucocutaneous tumors in horses.
  • The data showed that there was a significant concern about squamous cell carcinoma (SCC) during routine examinations compared to other kinds of tumors like sarcoids and melanomas.
  • Interestingly, the level of concern over sarcoids was greater during pre-purchase evaluations compared to routine clinical exams.
  • Moreover, there seemed to be a trend of increasing concern for melanomas during pre-purchase examinations, although the difference was not statistically significant.

Usage of Histopathology

  • One of the key findings in the report was a significant association between the kind of tumor and the use of histopathology — a lab test that studies tissues under a microscope to identify disease.
  • Among the different types of tumors, histopathology was used less frequently in cases of melanoma.
  • Financial factors seemed to be an important reason behind not using histopathology, suggesting that cost may be a barrier in the diagnostic process for some veterinarians.

Owners and Buyers’ Concerns

  • According to the veterinarians in the study, potential buyers appeared to be more concerned about the presence of sarcoids and melanomas than regular owners during pre-purchase exams.
  • This distinction implies that the perceived health risk of the horse might be affecting buyer decisions.

Key Implications and Recommendations

  • The study suggests the need for further training and education in equine oncology for veterinarians to improve their diagnostic and therapeutic practices.
  • Greater knowledge can aid in early detection and treatment, and can also better inform and reassure horse owners and potential buyers about these types of tumors.
