Immunophenotype (T cell versus B cell lymphoma)does not appear to be associated with prognosis in cats as it can be in dogs. Factors indicating a better prognosis (overall survival) in cats include:

Immunophenotype (T cell versus B cell lymphoma)does not appear to be associated with prognosis in cats as it can be in dogs. Factors indicating a better prognosis (overall survival) in cats include: an early presentation, a complete initial response to treatment and a clinically well patient(‘substage a’ disease).

** Early presentation

 

** A complete initial response to treatment

In cats, response rate to induction chemotherapy is 26-79% and thus there is an apparently a poorer response rate in cats compared with dogs, however, 30-40% of cats that do have complete remission will maintain complete remission for two years or more and long-term maintenance chemotherapy can frequently be stopped and many will then live free of disease. Hence, dogs may have higher remission rates but are less likely than cats to be able to maintain remission without chemotherapy.
