Cat Gastrointestinal Lymphoma Management

Small cell gastrointestinal lymphoma is one of the most common cancers in older cats, with treatment offering good quality of life and extended survival.

Key Facts

Small cell (low-grade) gastrointestinal lymphoma is most common in cats over 9 years
The distinction from IBD requires histopathology and sometimes molecular testing
Chlorambucil and prednisolone combination therapy produces response rates over 70%
Median survival times of 2+ years are achievable with appropriate treatment
Quality of life is generally maintained well during chemotherapy for small cell lymphoma

Welfare Considerations

Cats with gastrointestinal lymphoma experience weight loss, vomiting, and reduced appetite that impair quality of life before treatment. Chlorambucil is well tolerated with minimal side effects in most cats, making treatment welfare-positive. Prednisolone improves appetite and general wellbeing rapidly after starting treatment. The chronic nature of the condition requires long-term monitoring and occasional medication adjustments. Regular quality of life assessment helps owners and vets maintain treatment appropriateness.

What You Can Do

Pursue definitive diagnosis with biopsy before committing to long-term treatment
Give chlorambucil and prednisolone consistently on the prescribed schedule
Monitor body weight weekly as an indicator of treatment response
Schedule regular rechecks to assess abdominal disease progression by ultrasound
Discuss quality of life assessment tools with your vet for ongoing monitoring
