+ Biologic Behavior
- 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 techniques: 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
