Cytologic features and diagnostic accuracy of analysis of effusions for detection of ovarian carcinoma in dogs.

Background: Presence of an abdominal effusion is a typical presenting sign associated with ovarian carcinoma (OC) in dogs.

Objectives: The aims of this study were to describe the cytologic features of effusions associated with OC and to evaluate the diagnostic accuracy of such features for the diagnosis of OC in dogs.

Methods: Cytologic evaluations of 7 OC-associated peritoneal effusions in dogs were used to define cytomorphologic features of this neoplasm.

Clinical relevance of serial determinations of lactate dehydrogenase activity used to predict recurrence in dogs with lymphoma.

Objective: To evaluate whether serial determinations of serum lactate dehydrogenase (LDH) activity in dogs with lymphoma could be used to predict outcome and assist in early recognition of disease progression.

Design: Prospective cohort study.

Animals: 50 dogs with lymphoma.
