The management of feline lymphosarcoma

Lymphoma may occur in almost any site, in a cat of any age, in either a FeLV-infected or uninfected animal. As the most common tumor type found in this species, LSA should be included in the differential diagnosis for virtually any clinical problem in any body system. For the unusual forms of this malignancy, just as for the more common types, the prognosis and response to cytotoxic therapy is generally based on the pretreatment volume and location of the tumor, as well as on the overall status of the cat. Dramatic differences have been noted in the sensitivities of some of the various forms of LSA to conventional chemotherapy. Recognizing these differences and managing our patients and their owners accordingly should make the treatment of this disease far more rewarding.
