title: Doxorubicin alone or in combination with asparaginase, followed by cyclophosphamide, vincristine, and prednisone for treatment of multicentric lymphoma in dogs: 121 cases (1987-1995).
abstract: OBJECTIVE
  To determine response rate and remission as well as survival times for dogs with multicentric lymphoma treated first with doxorubicin alone or in combination with asparaginase and then with cyclophosphamide, vincristine sulfate, and prednisone (CVP) and to identify prevalence of toxicoses associated with this protocol and factors associated with prognosis.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  121 dogs.
  
  
  METHODS
  Variables evaluated for prognostic value were initial response rate to chemotherapy, age, breed, sex, body weight, histologic grade, clinical stage and substage, previous corticosteroid treatment, and serum calcium concentration.
  
  
  RESULTS
  Median overall remission and survival times for all 121 dogs were 205 and 237 days, respectively. Response rate (complete or partial response) was 88%. Ten dogs were hospitalized because of toxicoses associated with doxorubicin, and 19 dogs were hospitalized because of toxicoses associated with CVP. Asparaginase favorably influenced the initial response rate, but did not significantly influence overall remission of survival times. Initial response rate to chemotherapy, body weight, clinical substage, and serum calcium concentration was found to have prognostic value.
  
  
  CONCLUSIONS
  For dogs with multicentric lymphoma, treatment with doxorubicin alone or in combination with asparaginase and then with CVP resulted in an acceptable response rate and low prevalence of toxicoses.
