Squamous Cell Carcinomas in Horses: An Update of the Aetiopathogenesis and Treatment Options.

The research article discusses squamous cell carcinomas (SCCs), a prevalent type of tumor found in both the skin and non-skin parts of horses, highlighting its aetiology, pathogenesis, and the available treatment options.

Aetiopathogenesis of Squamous Cell Carcinomas in Horses

The study examines the origin and development of squamous cell carcinomas, a commonly observed type of tumor in horses. It discusses the following:

• The locations where these tumors are usually found, which ranges from dermatologic (skin-related) to non-dermatologic areas within a horse’s body.
• How at the point of first detection, SCCs are often already in an advanced state, which frequently involves metastasis – the spread of the disease from the initial site to different parts of the body. This calls for a comprehensive staging workup to assess the extent of disease spread.

Treatment Options for Squamous Cell Carcinomas in Horses

The study then elaborates on the various treatment methods available for SCCs. It brings attention to the principles and rationale behind the following approaches:

• Wide surgical excision, which entails the removal of the tumor along with a significant margin of normal tissue around it. This method is often the first choice of treatment, as the paper suggests.
• However, there is a high recurrence rate for SCCs despite surgical intervention, which necessitates the consideration of adjunctive therapies. Such additional treatments are meant to complement the primary surgery and improve the chances of a better long-term prognosis.

The paper emphasizes the importance of understanding the extent and spread of the disease to guide treatment planning and assess the prognosis adequately.
