Plain-English summary
A 7-year-old male domestic cat was brought in with gastrointestinal issues and an abdominal mass, which turned out to be a type of cancer called large granular lymphocyte lymphoma (LGLL). The cat was treated with a combination of chemotherapy drugs and an additional therapy using activated lymphocytes. Remarkably, the cat lived for 982 days after starting treatment with only a few side effects. This case suggests that combining these therapies can be a safe and effective option for cats with this serious condition.

Abstract
BACKGROUND: Feline large granular lymphocyte lymphoma (LGLL) is a grave prognosis. However, the effectiveness of concurrent treatment with chemotherapy and activated lymphocyte therapy for feline LGLL has not been evaluated. CASE DESCRIPTION: A 7-year-old, castrated male, domestic cat presented with gastrointestinal symptoms and an abdominal mass. A Tru-Cut biopsy of the mass revealed LGLL. The cat responded well to chemotherapy regimens of cyclophosphamide, vincristine, prednisolone, and L-asparaginase. Furthermore, activated lymphocyte therapy was added as an adjuvant treatment. The cat survived 982 days from the first presentation and experienced few adverse events. Necropsy was performed and immunohistochemistry revealed that the neoplastic lymphocytes were CD3/CD20cells. The final diagnosis was non-T/B LGLL. CONCLUSION: Minimal physical burden and a good initial response to chemotherapy might have contributed to long-term survival in the present case. Moreover, activated lymphocyte therapy could be performed safely and may be a feasible treatment for feline non-T/B LGLL.
