Q

Differential diagnosis of esophageal tumors

A

SCC

Leiomyosarcoma

24
Q

feline esophageal SCC tumor

A

females.

Middle 1/3rd, caudal to thoracic inlet

25
Q

Esophageal work up and staging

A

Imagining - megaesophageus?
Esophagoscopy (GS)- biopsy
fecal

26
Q

Esophageal tumor therapy

A

Surgery!
best for low grade leiomyosarcomas
RT - limited
Palliation - feeding tube

27
Q

Esophageal tumor prognosis

A

Very poor

benign/low grade/LSA can be okay

28
Q

Drug to resolve S. lupi infection

A

Dormectin

29
Q

Gastric tumors

A

uncommon
males
chronic gastritis, helicobacter
Asymptomatic until blocking outflow - anorexia/hematemesis

30
Q

Gastric tumor genetic predilection

A

Belgian shepherd, chows

Benign - beagles

31
Q

Gastric Tumor dog differentials

A

Big 2
Adenocarcinoma (70-80%)
Leiomyosarcoma

32
Q

Gastric tumor Cat differentials

A

Big 1

Lymphoma

33
Q

Cat systemic status w/ gastric lymphoma

A

negative FeLV

possible concurrent LSA in small intestine

34
Q

Gastric ademocarcinoma

A

predictable - pyloric antrum/lesser curvature
Scirrhous (leather)
High met rate (anywhere)
deeply ulcerative

35
Q

Gastric work up and staging

A

Non specific lab
Abdominal US (decreased motility)
ENDOSCOPY - biopsy

36
Q

Gastric leiomyomas

A

well circumscribed, submucosal mass

cardiac location - benign

37
Q

Gastric tumor Treatment

A

Surgical excision
partial gastrectomy
gastroduodenostomy/jejunostomy (bilroth 1 or 2) - high morbidity

38
Q

Gastric tumor prognosis

A

surgical excision, tumor type/grade, mets.

39
Q

ACA Gastric tumor prognosis

A

poor - majority dead in 6m

40
Q

LSA Gastric tumor prognosis

A

Doesn’t respond to chemo,

resect and chemo might not be needed

41
Q

Leiomyosarcoma Gastric tumor prognosis

A

12-21m

Cured with aggressive surgery

42
Q

Intestinal tumors

A

older animals, same presentation as gastric tumors

43
Q

Intestinal tumor Dog

A

uncommon
Large intestine!
Collie, GSD, male

44
Q

Intestinal tumor cat

A

uncommon

Small intestine!

45
Q

Intestinal tumor work up/staging

A

similar to gastric -
Goal: rule out LSA (no sx tx)
endoscopy (understand limits)
US guided FNA/cytology

46
Q

Intestinal tumor differential diagnosis dog

A

Big 3
LSA > ACA > Leiomyosarcoma
GIST

47

Big 3
LSA, ACA, MCT
no order

48

A

Exploratory laparotomy - R&A
except LSA
4-8cm margins
assess mesenteric and regional lnn

T cell, multifocal
not good remission or survival
Neg prog. factors: Failed to achieve remission

50
Q

LSA intestinal Tumor CAT

A

responds well to chemo

prognostic factor: response to tx

51
Q

ACA intestinal tumor dog

A

44% met rate - stage!

female neg prognosis?

52
Q

ACA intestinal tumor cat

A

72% mets on dx

neg prognostic: histo subtype and mets

53
Q

MCT intestinal tumor dog

A

100% mortality in 2m.
100% met rate.
BAD

54
Q

MCT intestinal tumor cat

A

poor - euthanize/death

*solitary MCT w/o mets have good survival

55
Q

Leiomyosarcoma intestinal tumor

A

old data.
8m MST dogs
cat - very uncommon

IHC can differentiate from leiomyosarcoma
from cells of cajal (GI pacemaker)
express c-kit
predilection for cecum
die from septic peritonitis (ruptured mass)
