Gastric squamous cell carcinoma in three horses.

The research discusses the diagnosis of gastric squamous cell carcinoma, a type of stomach cancer, in three horses. All observed horses showed similar symptoms: weight loss, lack of appetite, lethargy, and presence of inflammatory exudates.

Study Context

• The study involves case reports of three horses that were diagnosed with gastric squamous cell carcinoma.
• This type of cancer, rare in horses, primarily starts in the oesophageal region of the stomach and then spreads (metastasizes) to other parts of the body.

Clinical Signs and Symptoms

• All three horses exhibited weight loss, anorexia (loss of appetite), and lethargy.
• Respiratory issues were a prominent symptom observed in one of the horses indicating possibly advanced stages of the disease or metastasis to the respiratory system.

Medical Examination

• On examination, all three horses had decreased albumin and increased globulin and fibrinogen concentrations, signifying an underlying infection or inflammation.
• Two of the horses showed mild signs of anemia.
• Inflammatory exudates, a characteristic sign of infection or inflammation, were found in the peritoneal (abdominal) cavities of all horses.
• Cytological evaluation (microscopic examination of cells) confirmed the presence of squamous cell carcinoma in two of the horses.

Diagnosis and Prognosis

• Pleural fluid (fluid from the lung cavity) samples were taken from two of the horses, and these were categorized as inflammatory exudates as well. However, no cancerous cells were initially detected in these samples.
• In all three cases, the cancer originated in the esophageal region of the stomach and had metastasized throughout the abdomen.
• In two cases, the cancer had spread to the pleural cavity, indicating advanced stages of the disease.
• The study does not provide direct information on treatment or prognosis for the horses, but the widespread metastasis suggests a poor prognosis.

This research brings valuable insight into the clinical and diagnostic features of gastric squamous cell carcinoma in horses, which can be helpful in early detection and timely treatment strategies in veterinary medicine.
