State Gastrointestinal Cancer (GI Tract Cancer) in Animals

 

In dogs and cats, gastrointestinal (GI) neoplasms are rare; of all neoplasms, stomach tumours account for less than 1% of cases, whereas intestinal tumours account for less than 10%. There is no known specific etiologic agent for GI neoplasia.

While cats and dogs with GI neoplasms typically range in age from 10 to 12 years, older canines are more likely to develop gastric leiomyomas (average age of 15). Certain findings indicate a modest tendency for GI neoplasia in male dogs and cats.

Dogs and cats with GI neoplasms typically have malignant ones. You can submit a guest post on health and share your experiences over that.

The Signs of Having Gastrointestinal Cancer in Animals

The location and size of the tumour, as well as any potential metastases or paraneoplastic disorders (such as hyperglycemia or hypoglycemia), determine the clinical manifestations of GI neoplasia. The following are the most typical clinical indicators of GI neoplasia:

• Vomiting
• Anorexia
• Weight loss
• Diarrhoea
• Lethargy

How to Diagnose Gastrointestinal Cancer in Animals

There are  several ways to diagnose gastrointestinal cancer in animals. Some of them are mentioned below.

1. Hematology and Serology

It is common to find microcytic anaemia, with or without hypoproteinemia, when ulcerated masses and continuous blood loss occur.

Acid-base and electrolyte imbalances, which might include hypochloremia, hypokalemia, and metabolic alkalosis or acidosis, can be indicators of persistent vomiting. Intestinal adenocarcinoma and lymphoma have been linked to paraneoplastic hypercalcemia.

2. Abdominal Imaging

Certain cases of GI lymphoma may also be accompanied by splenomegaly and/or hepatomegaly, as well as enlarged regional lymph nodes.

A normal appearance does not rule out neoplasia, especially in the stomach, even though abnormal results on ultrasonography may suggest the condition's existence.

3. Thoracic Imaging

While thoracic imaging, such as computed tomography and/or three-view radiography, is not frequently used to report GI neoplasms in dogs and cats, it can indicate the presence of pulmonary metastases. When considering surgery, these staging tests are crucial for determining prognosis.

4. Endoscopy

Partial-thickness biopsy and detection of GI neoplasia can be aided by GI tract endoscopy. Nevertheless, since some GI tumours are submucosal and this method may only collect superficial mucosa, endoscopic biopsy collection is constrained by the biopsy's small size and superficial nature.

5. Histologic and Molecular Diagnose

For GI samples, immunohistochemistry can be necessary in addition to histology to distinguish between different neoplasia types.

When used to inconclusive biopsy sections, particularly in cats, PCR for antigen receptor rearrangement (PARR) can assist in the diagnosis of GI lymphoma by detecting clonally rearranged antigen receptor genes by the amplification of conserved gene segments.
