Oral and GI Neoplasia Flashcards
(18 cards)
What are the common clinical signs of oral tumors?
Mass in mouth
Halitosis
Dysphagia
Bloody discharge
Loose teeth
Drooling
Poor grooming
What is the diagnostic work-up for oral tumors?
Incisional biopsy best (AVOID GOING THROUGH LIP OR CHEEK and record exactly where the lesion is)
FNA difficult
Thoracic rads, FNA LN if enlarged, abdominal US
CT indirect lymphography to identify at-risk lymph nodes
What are the perioperative side effects of maxillectomy/mandibulectomy?
Bleeding
Dehiscence
SQ emphysema, synchronous skin motion
Bloody sneezes
Bruised appearance
What are the possible complications associated with maxillectomy/mandibulectomy?
Transfusion
Fistula
Malocclusion
Incomplete resection
What are the temporary lifestyle modifications that need to be made with maxillectomy/mandibulectomy?
Soft food for 1 months
Low key activity for 2 weeks
No objects in mouth for 1 months
What are the permanent changes associated with maxillectomy/mandibulectomy?
Epiphora
Desensation
Conformation change, functional eye
Normal mouth and nose use
With oral tumors, what is the appropriate dose of surgical resection?
If tumor touches bone, bone has to go!
What is the treatment for an oral fibrosarcoma? Prognosis?
Complete surgical resection
18-24m MST
What are the clinical signs of a “Hi Lo” FSA?
Facial deformity, bone destruction
Firm mass, smooth, non-ulcerated
What is important to note about “Hi Lo” FSA?
Previously dx as fibroma, fibrous tissue, scar tissue, inflammation on histology
Very benign on histology
Very invasive!! (requires larger surgical margins)
Low metastatic rate, high local recurrence!
Does surgical debulking improve the prognosis of oral tumors?
No
What are the most common small intestinal tumors in dogs and cats?
What are the common clinical signs of intestinal tumors?
Weight loss
Vomiting
Melena or tenesmus
Abdominal mass on palpation
Anemia
What diagnostics should be done for a suspected intestinal mass?
Abdominal rads = obstructive pattern or mass effect
Abdominal US = LNs, guide FNA
Exploratory laparatomy
What is the treatment for solitary or obstructive tumors?
Surgery
Resection and anastamosis, gastric resection, rectal pull through
Palliation (stenting, rerouting, bypass)
What is the treatment for diffuse intestinal lymphoma?
Chemotherapy
What are positive prognostic factors of intestinal neoplasia?
Solitary mass
Complete margins
Response to chemo in cats with lymphoma
Pendunculated vs annular colorectal adenocarcinoma
What are negative prognostic factors of intestinal neoplasia?
Metastasis to lymph node, lung, peritoneum
