Case Summary:
This report describes a 10-year-old female spayed Russian Blue cat presented with a 5 month history of respiratory difficulty. Thoracic radiographs were suggestive of a central airway obstruction. Bronchoscopy revealed a broad-base mass in the region of the carina. Bronchoscopic debulking was performed using a urinary catheter. Histopathology confirmed the presence of a tracheobronchial carcinoma. Survival from diagnosis was 16 months (480 days), over which time the cat underwent three endoscopic debulking procedures in combination with doxorubicin chemotherapy.
Relevance And Novel Information:
To our knowledge, this is the first report of a tracheobronchial carcinoma in a cat treated by endoscopic debulking with a urinary catheter and adjuvant chemotherapy with long-term survival time. A review of interventional bronchoscopy performed in humans and in veterinary medicine is described.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
