Gastric neoplasia best treated surgically


Radiographic abnormality may include gastric distension. Contrast studies confirm delayed gastric emptying and appreciate luminal narrowing of the stomach from associated neoplasia. Endoscopy has largely replaced the use of contrast studies in the diagnosis of gastric neoplasia.

Full-thickness biopsies are required if endoscopic biopsies are non-diagnostic. The ultrasonographic appearance usually shows irregularly thickened, hyperechoic-to-hypoechoic layering in the gastric wall and a poorly defined gastric lumen. Enlarged gastric lymph nodes and metastatic disease in regional tissues may also be noted.

Treat surgically Benefits from chemotherapy and radiation therapy for management of gastric adenocarcinoma are nil. Gastric adenocarcinoma is best treated surgically.

When the entire gastric tumor is removed and there is no evidence of metastasis to surrounding lymph nodes or organs at the time of surgery, the prognosis is still guarded, meaning that recurrence of the tumor is likely even in this case. To monitor for progression of the neoplastic process, physical examination and abdominal and thoracic radiography at one, three, six, nine and 12 months after surgery are done and owners are instructed to watch daily for melena.

The average life expectancy after surgery for this type of tumor is probably only six months to a year, but dogs do seem to be comfortable most of that time.

Veterinary surgeons tend to be optimistic by nature. It takes a certain amount of optimism just to do surgery, considering the risks of anesthesia and routine surgical procedures and then to want to take on the added risks of removing portions of vital organs just takes an attitude in which a person believes things will turn out all right. Veterinarians who practice primarily medicine tend to be a little more pessimistic, especially about surgical outcomes. Oncologists tend to be somewhere between these extremes, so the fact that the oncologist feels that there is a 50 percent chance of a cure is pretty good.
