Case History: A 6-year-old, entire male Flat-coated Retriever was presented with a history of lethargy, polydipsia and seizures. Clinical chemistry had shown marked azotaemia.

Clinical Findings And Diagnosis: Radiography and ultrasonography revealed bilateral renomegaly, and cytology of fine needle aspirates from the kidneys was diagnostic of malignant lymphoma. The dog was treated with a modified high-dose cyclophosphamide-, vincristine-, and prednisolone-based chemotherapy protocol, achieved remission, and returned to normal quality of life. Survival time was 346 days from the time of diagnosis.

Clinical Relevance: Malignant lymphoma in the kidneys of dogs has been considered to carry a uniformly poor prognosis. Long-term remission after medical treatment has not previously been reported. The favourable outcome in this case illustrates the limitations of clinical staging in determining the outcome for individual patients.

Older patients represent a unique and vulnerable subgroup, requiring careful consideration when determining treatment options. Treatment-related leukoencephalopathy is commonly observed in older patients months to years after receiving radiotherapy and/or methotrexate for primary central nervous system lymphoma (PCNSL). Tirabrutinib is an orally available, highly selective, and potent second-generation Bruton's tyrosine kinase inhibitor (BTKi) approved for treating recurrent/refractory PCNSL in Japan.

Background Lung cancer is the most frequent cause of cancer-related deaths and the most common type of cancer globally. It is generally classified into two main histologic subtypes: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most prevalent type and is enriched with genetic and molecular diversity.

Potential CD19 antigen loss following CD19-directed therapy has raised concerns over sequential use of these therapies. Tafasitamab, a CD19-targeting immunotherapy, combined with lenalidomide, is approved for relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) treatment in adults ineligible for autologous stem cell transplantation. This retrospective analysis examined characteristics and outcomes of adults with R/R DLBCL who received tafasitamab preceding CD19-directed chimeric antigen receptor T-cell (CAR-T) therapy in a real-world setting.
