===Adjuvant Chemotherapy===

Has been shown to significantly improve survival times for cats with adenocarcinoma.

Doxirubicin as been shown to significantly improve survival times for cats with colonic adenocarcinoma with a median survival time of 56 and 280 days for those not receving and those receiving chemotherapy respectively. No other evidence exists to confirm the benefits of adjuvant chemotherapy in dogs or cats.

 

Rarely reported due to concerns of intolerance of surrounding tissues, in addition it cannot be relied upon that the same target will be irratiated each day due to intestinal mobility.

==Prognosis==

==Prognosis==

If no metastasis has occurred long term survival may be achieved following excision of the tumour. The rate of metastasis of adenocarcinoma to the local lymph nodes for both dogs and cats is approximately 50%. Without surgical intervention the mean survival of dogs with small intestinal adenocarcinoma is 12 days and reports varying from 114 days to 7-10 months with surgical treatment.
