Fibrosarcoma is an aggressive soft tissue tumor causing significant welfare harm. Welfare management requires wide surgical excision and consideration of quality of life throughout treatment.
Fibrosarcoma poses significant welfare challenges because of its aggressive local behavior and tendency to recur after incomplete excision. The location — often on limbs or the oral cavity — means that achieving adequate surgical margins requires major procedures. Mandibulectomy for oral fibrosarcoma eliminates severe bone-invading pain but requires significant adaptation to altered eating and jaw function. Most dogs adapt remarkably well to these changes.
Local recurrence after incomplete excision causes welfare harm through pain from infiltrative growth. Pre-surgical planning using MRI to define margins, followed by wide excision, reduces recurrence risk. Radiation therapy provides additional local control in areas where complete resection is anatomically impossible. Throughout treatment, quality of life monitoring guides decisions about continuing aggressive therapy versus shifting to palliative care.
