Estimated prevalence of injection-site sarcomas in cats during 1992.

To obtain an estimate of the yearly prevalence of injection-site sarcomas in cats. Mail survey of members of the American Association of Feline Practitioners. A questionnaire was sent to 1,112 veterinarians. 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). Results suggest that injection-site sarcomas were rare during 1992.
