Surgical resection and anastomosis is the treatment of choice for both small and large intestinal adenocarcinoma. For small intestinal lesions, a margin of 4-8cm  is resected, and anastomosis may be achieved by suturing or stapling with no difference in outcome. Extraserosal invasion or adhesions may cause difficulties during resection and, for duodenal lesions, care must be taken to ensure there is no iatrogenic damage to the biliary or pancreatic ducts. Regional lymph nodes should be removed if there is evidence of metastasis. For colorectal adenocarcinomas, large margins may be more difficult to achieve for colorectal lesions due to restricted access. Transcolonic debulking is a palliative alternative for obstructive large intestinal lesions. For all types of surgery, postoperative complications include peritonitis and sepsis.

Adjunctive chemotherapy in the form of doxirubicin has been shown to significantly improve survival times for cats with colonic adenocarcinoma, with median survival times improved from 56 to 280 days when doxorubicin treatment was used. No other evidence exists to confirm the benefits of adjuvant chemotherapy in dogs or cats. Piroxicam, a non-steroidal anti-inflammatory drug may have palliative effects for large intestinal and rectal lesions.

The use of radiotherapy in intestinal adenocarcinoma has not been subject to detailed investigations due to the relative intolerance of the surrounding tissues to radiation. As well as potential to cause intestinal perforations or adhesions, intestinal motility means that there is no certainty the same target will be irradiated each day. In a report of single high-dose irradiation used against a surgically-exposed anorectal tumour, no long-term side effects were observed.

Stool softeners may be useful in cases where an annular tumour causes constriction of the bowel lumen.
