Standard of care treatment of dogs with multicentric lymphoma includes combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP); however, owners may be hesitant to commit the resources necessary to complete a lengthy, multi-drug protocol. One hundred thirty-four client-owned dogs with multicentric lymphoma were treated with a 15-week CHOP chemotherapy protocol. The overall response rate was 98% with 104 dogs experiencing a complete response (CR). The median progression-free survival (PFS) time for all dogs was 176 days, and the median disease-specific overall survival time was 311 days. Prognostic factors identified on multivariate analysis as significant for PFS included substage, immunophenotype, hospitalization for adverse events, need for dose reduction, presence of neutrophilia at diagnosis, presence of anemia and experiencing a CR as best response to therapy. In conclusion, this protocol may be a viable alternative to CHOP protocols using a larger number of treatments.
