Estimated prevalence of injection-site sarcomas in cats during 1992

OBJECTIVE: To obtain an estimate of the yearly prevalence of injection-site sarcomas in cats. DESIGN: Mail survey of members of the American Association of Feline Practitioners. PROCEDURE: A questionnaire was sent to 1,112 veterinarians. RESULTS: 235 responses were sufficiently complete for inclusion in the study. Overall, responding veterinarians reported 744,993 cat visits in 1992, representing 434,638 individual cats (1.7 visits/cat). The estimated overall prevalence of injection-site sarcomas during 1992 was 0.00021 cases/cat visit (2.1 cases/10,000 cat visits) or 0.00036 cases/cat (3.6 cases/10,000 cats). CLINICAL IMPLICATIONS: Results suggest that injection-site sarcomas were rare during 1992.
