==Prognosis==
==Prognosis==
There is significant perioperative risk associated with cats with small intestine [[Adenocarcinoma|adenocarcinoma]] with a high mortality rate within the first two weeks following surgery. However, after these two weeks long term control may be achieved. For cats with large intestinal [[Adenocarcinoma|adenocarcinoma]] survival time after surgery alone has been reported as approximately 4.5 months.
If no metastasis has occurred long term survival may be achieved following wide excision of a well differentiated small intestinal tumour. The rate of metastasis of adenocarcinoma to the local lymph nodes for both dogs and cats is approximately 50%.
In dogs, the overall prognosis is poor. Animals with pedunculated rectal adenocarcinomas have a better prognosis than other tumour locations or forms, but in all instances many cases recur locally or experience metastasis. Without surgical intervention, the median survival of dogs with small intestinal adenocarcinoma is 12 days, and following resection this is improved to around 10 months. A pedunculated olorectal adenocarcinoma has a median survival time of 32 months after excision, but annular tumours have a much worse prognosis with a survival of around 1.6 months.
There is significant perioperative risk associated with cats with small intestine adenocarcinoma with a high mortality rate within the first two weeks following surgery. However, after these two weeks long term control may be achieved. For cats with large intestinal adenocarcinoma survival time after surgery alone has been reported as approximately 4.5 months, and survival of over one year has been reported in small intestinal cases.
