Flashcards in GI Oncology Deck (23)
Best treatment option for lipomas?
Tests for staging oral melanoma?
FNA of lymph nodes (regardless of size)
Best 2 options for treatment of oral neoplasms?
What two factors impact survival time for oral neoplasms the most?
size (affects ability for it to be removed) and metastasis
Overall survival time for oral neoplasms?
~1 year (up to 2 years if small)
1) benign oral tumors
2) malignant oral tumors
2) melanoma (also SCC, fibrosarc, and osteosarc)
Two treatment options for acanthomatous tumors (epulides)?
Surgery-- <5% recurrence with good margins
Radiation (better control with smaller tumors)
When would you choose conservative vs. aggressive surgical excision for AGASACA
aggressive if small & no mets
conservative if larger mass and risk for fecal incontinence
MST for AGASACA if it's a small mass with no mets, no hypercalcemia, and it's able to be excised?
MST for AGASACA if negative prognositc factors are present
How is nodular hyperplasia of the liver treated?
Don't treat (not a problem)
maybe give liver support (i.e Denamarin)
Treatment options for hepatocellular carcinoma:
1) diffuse form
2) massive form
1) maybe chemo but poor prognosis
2) lobectomy can add years even with incomplete margins
the #1 malignant oral neoplasm in cats?
Squamous cell carcinoma (ulcerative)
Feline oral SCC is not typically responsive to which type of treatment?
(surgery with or without radiation is best)
Most commonly diagnosed lymphoma in cats
GI lymphoma (small intestinal, small cell, diffuse lymphoma)
Best option for diagnosis of feline GI lymphoma?
exploratory laparotomy with biopsy (endoscopy alone won't let you reach middle of the bowel)
Treatment for feline small cell GI lymphoma is based on?
(High grade=multi-agent protocols)
Prognosis (MST) for GI lymphoma if:
1) low grade
2) high grade
3) non-responsive to tx
2) <1 year
Other differentials for a mid-abdominal mass in a cat?
Chronic renal failure
Most common gastric neoplasm in dogs?
Which method of diagnosis is not preferred for gastric neoplasms?
Endoscopy...can only take a superficial biopsy which won't include the tumor cells
Which gastric neoplasm may be responsive to treatment with tyrosine kinase inhibitors
GIST (stromal tumor)
