1

Best treatment option for lipomas?

surgical removal

2

Tests for staging oral melanoma?

FNA of lymph nodes (regardless of size)
Thoracic radiographs

3

Best 2 options for treatment of oral neoplasms?

Surgical excision
Radiation therapy

4

What two factors impact survival time for oral neoplasms the most?

size (affects ability for it to be removed) and metastasis

5

Overall survival time for oral neoplasms?

~1 year (up to 2 years if small)

6

Most important:
1) benign oral tumors
2) malignant oral tumors

1) epulides/ameloblastoma

2) melanoma (also SCC, fibrosarc, and osteosarc)

7

Two treatment options for acanthomatous tumors (epulides)?

Surgery-- <5% recurrence with good margins

Radiation (better control with smaller tumors)

8

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

9

MST for AGASACA if it's a small mass with no mets, no hypercalcemia, and it's able to be excised?

~1.5 years

10

MST for AGASACA if negative prognositc factors are present

~7months

11

How is nodular hyperplasia of the liver treated?

Prognosis?

Don't treat (not a problem)
maybe give liver support (i.e Denamarin)

Good

12

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

13

the #1 malignant oral neoplasm in cats?

Squamous cell carcinoma (ulcerative)

14

Feline oral SCC is not typically responsive to which type of treatment?

chemotherapy

(surgery with or without radiation is best)

15

Most commonly diagnosed lymphoma in cats

GI lymphoma (small intestinal, small cell, diffuse lymphoma)

16

Best option for diagnosis of feline GI lymphoma?

exploratory laparotomy with biopsy (endoscopy alone won't let you reach middle of the bowel)

17

Treatment for feline small cell GI lymphoma is based on?

Grade
(High grade=multi-agent protocols)

18

Prognosis (MST) for GI lymphoma if:
1) low grade
2) high grade
3) non-responsive to tx

1) ~1year
2) <1 year
3) weeks

19

Other differentials for a mid-abdominal mass in a cat?

GI lymphoma
IBD
Hyperthyroid
Chronic renal failure
Diabetes mellitus

20

Most common gastric neoplasm in dogs?

adenocarcinoma

21

Which method of diagnosis is not preferred for gastric neoplasms?

Endoscopy...can only take a superficial biopsy which won't include the tumor cells

22

Which gastric neoplasm may be responsive to treatment with tyrosine kinase inhibitors

GIST (stromal tumor)

23

MST of gastric adenocarcinomas and mast cell tumors?

2 months (ACA)
<6 months (MCT)
