Feline Gastric Lymphoma
Also known as: Stomach Lymphoma
⚠ Emergency Warning Signs
Significant, persistent vomiting or inability to keep food down warrants prompt veterinary evaluation.
Overview
A form of lymphoma specifically affecting the stomach, one of the possible locations for gastrointestinal lymphoma alongside the intestine (covered in another entry) — while both share the general lymphoma treatment approach, stomach-specific involvement can cause somewhat different symptom emphasis given this organ's role in initial food processing.
Symptoms
- Vomiting
- Weight loss
- Decreased appetite
Causes
Represents lymphoma cells specifically infiltrating stomach tissue; the underlying cause of feline lymphoma generally isn't always clearly identified in current cases. Lymphoma affecting the stomach specifically can be difficult to distinguish from inflammatory bowel disease affecting the same location without biopsy, since both can cause similar thickening of the stomach wall on imaging.
Risk Factors
Older age is a general risk factor for lymphoma; no other specific established risk factor for this particular location.
Transmission
Not directly contagious; a historical FeLV association exists for lymphoma generally, though less dominant in current cases.
Incubation Period
Not applicable in the infectious sense; develops gradually as lymphoma cells progressively infiltrate stomach tissue.
Disease Stages & Progression
Progressive stomach wall infiltration by lymphoma cells can affect normal stomach function, causing symptoms related to digestion and food processing, with severity depending on how much stomach tissue is affected and how this impacts normal function.
Early Warning Signs
Vomiting, decreased appetite, and weight loss.
Advanced Symptoms
More significant vomiting, substantial weight loss, and in some cases, symptoms related to stomach outlet obstruction if the tumor significantly affects normal food passage into the intestine.
Diagnostic Methods
Endoscopic biopsy of the affected stomach tissue provides definitive diagnosis, confirming lymphoma and distinguishing this from other stomach conditions.
Veterinary Examination Process
Assessment of vomiting pattern, appetite, and weight, with endoscopy providing definitive diagnostic tissue.
Recommended Lab Tests
FeLV/FIV testing, complete blood count, and endoscopic biopsy.
Diagnostic Imaging
Abdominal ultrasound can show thickened stomach wall tissue; endoscopy allows direct visualization and biopsy.
Blood Test Indicators
FeLV/FIV testing, general bloodwork.
Biopsy / Histopathology
Essential for diagnosis, confirming lymphoma specifically.
Differential Diagnoses
Other stomach conditions including gastritis and gastric ulceration — endoscopic biopsy confirms lymphoma specifically.
Home Monitoring Guidance
Not a substitute for veterinary evaluation of persistent vomiting and weight loss.
Veterinary Treatment Options
Chemotherapy, following standard feline lymphoma protocols, is the primary treatment approach. Chemotherapy is the standard treatment, with the specific protocol and outlook depending on how localized the disease is to the stomach alone versus involving other digestive organs as well.
Surgery Requirements
Not typically the primary treatment approach given chemotherapy's role as the standard treatment for lymphoma.
Recovery Timeline
Depends on treatment response; chemotherapy protocols extend over a defined treatment course.
Possible Complications
Progressive stomach dysfunction if untreated, potentially including outlet obstruction in significant cases.
Long-Term Management
Ongoing chemotherapy management and monitoring, similar to feline lymphoma management generally.
Prevention
No established prevention given the not-fully-understood cause of lymphoma generally in current cases.
Vaccination Availability
Not applicable directly, though FeLV vaccination provides indirect protection against that historically relevant contributing factor.
Prognosis
Variable, similar to feline lymphoma prognosis considerations generally, depending on response to chemotherapy treatment.

Frequently Asked Questions
How is this different from the intestinal lymphoma I've read about?
Both represent lymphoma affecting the digestive tract, but at different specific locations — this specifically involves the stomach, while the more commonly discussed form affects the intestine; treatment (chemotherapy) is generally similar regardless of the specific location, though the location can influence which symptoms are most prominent.
