Biologic Behaviour

  • oral FSA is the 2nd most common feline oral tumor with an incidence of 13%-17%
  • mean age 10 years
  • no site predilection ± gingiva
  • locally invasive into the gingiva and bone with local tumor recurrence after surgical excision common
  • bone involvement is common
  • metastasis to the regional lymph node is rare but metastasis to the lungs occurs in up to 20% cats

Treatment

  • surgical treatment: mandibulectomy and maxillectomy
  • radiation therapy can be used alone or in combination with surgical excision, but is considered palliative
  • chemotherapy: doxorubicin and cyclophosphamide for oral FSA

Prognosis

  • local control is more important than metastatic disease with local recurrence the most common cause of death
