| Abstract: | A total of 147 dogs treated with a combination of chemotherapy procedure (vincristine, L-asparaginase, cyclophosphamide, and methotrexate) were evaluated for response to therapy and the influence of age, sex, clinical stage, and body weight to duration of response. Complete response was achieved in 113 dogs (77%), partial response in 26 dogs (17.7%), and no response in 8 dogs (5.4%). The median survival time for the dogs with complete and partial responses was 265 days. An analysis of factors associated with prognosis revealed that age, clinical stage, and body weight were not associated with response to therapy, whereas sex was. Females had a significantly prolonged remission and survival time (P = 0.0001). |
