Retrospective Study |
From the Bay Area Veterinary Specialists (Jakubiak, Siedlecki, Zenger, Matteucci, Bruskiewicz, Rohn), 14790 Washington Avenue, San Leandro, California 94578 and the Donaldson-Atwood Cancer Clinic and Flaherty Comparative Oncology Laboratory (Bergman), Animal Medical Center, 510 East 62nd Street, New York, New York 10021.
Medical records of 27 cats with masses of the larynx and trachea were examined. Six cats had inflammatory masses, and 21 cats had neoplastic lesions. A definitive diagnosis was reached in 22 cats with a single biopsy. The median age of the cats was 12.0 years (range 6 to 20 years). Dyspnea was the most common clinical sign. Accurate diagnoses were best obtained through direct laryngeal or tracheal examination combined with histological examination of tissue biopsies. Kaplan-Meier survival data for all inflammatory and neoplastic lesions showed a median survival of 5 days, with 7.4% of cats alive at 1 year.
