+ Biologic Behavior

Feline tongue tumors are most commonly SCC on occur on the ventral surface of the tongue near the frenulum

+ Diagnosis

  • Wedge incisional biopsy closed with horizontal mattress sutures
  • Regional lymph node FNA for staging purposes

+ Treatment

  • Partial glossectomy if tumor is confined to the lateral or rostral half of the tongue
  • ± Radiation therapy if inoperable or metastatic to the regional lymph nodes

+ Prognosis

  • Prognosis depends on site, type, and grade of tumor
  • Drinking and eating may be impaired but hydration and nutrition can be maintained
  • Poor coat hygiene in cats due to effect of partial glossectomy on grooming
  • Thermoregulation can be a problem in hot and humid environments
  • Rostral tongue tumors have better prognosis as earlier detection and easier to excise with wider margins, while the caudal tongue has richer vascular and lymphatic supply for metastasis
  • 12-month survival rate 25%
