GENERAL CONSIDERATIONS

Feline Tracheal Tumors

  • primary tracheal neoplasms are rare in cats
  • tracheal tumors in cats include LSA, SCC, ADC, leiomyosarcoma, and adenoma
  • secondary involvement of the trachea with mediastinal LSA has been reported
  • mean age 9.5 years

DIAGNOSIS

Clinical Signs

  • paroxysmal intermittent coughing of several weeks duration
  • progressive worsening of dyspnea, stridor, and exercise intolerance
  • occasional retching produces hemorrhagic discharge
  • respiratory signs usually evident when > 50% diameter of airway obstructed
  • large masses may be palpable

Imaging

  • survey ± contrast bronchography with survey radiographs usually sufficient due to size of lesions at diagnosis
  • other radiographic signs include pulmonary over-expansion, flattening of the diaphragm, and prominent pulmonary vasculature secondary to increased air content in the lower airways
  • tracheoscopy provides positive diagnosis with samples collected for brush cytology and histopathology
  • CT or MRI used in humans

TREATMENT

Surgical Resection

  • resection and anastomosis
  • ± tracheal wall reconstruction or stenting

Other Treatment Options

  • other options include radiation therapy, chemotherapy, endoscopic removal, and photodynamic therapy

Prognosis

  • benign tracheal neoplasms have a good prognosis following complete resection
  • prognosis is good for cats with tracheal tumors:
  • survival times for LSA > 1-21 months
  • survival times for ADC > 3-12 months
