PURPOSE OF REVIEW: Transplantation of the intestine is a vital component in the treatment of many intrabdominal tumors. This is a comprehensive review of current practice and outcome of intestinal transplantation for tumors.
RECENT FINDINGS: Most commonly described for the intrabdominal desmoid tumor, excellent survival outcomes can be attained, particularly for the more aggressive desmoid tumors associated with familial adenomatous polyposis syndrome and early referral is critical in order to avoid diffuse tumor spread which would necessitate a more complex multivisceral transplant. Currently, consensus within the intestinal transplant community lists invasive intrabdominal desmoid tumor as a primary indication for intestinal transplantation. Rare tumors such as metastatic neuroendocrine tumors confined to the abdomen, and pseudomyxoma peritonei have been associated with acceptable survival and recurrence outcomes with intestinal transplantation in carefully selected patients who would otherwise have a dismal prognosis. In addition, intestinal transplantation is an option for patients with a history of abdominal malignancy who have been rendered with intestinal failure due to surgical complications from resection of a primary tumor.
SUMMARY: Intestinal transplantation is a therapeutic option with excellent results in selected patients with intrabdominal desmoid tumors, neuroendocrine tumors and pseudomyxoma peritonei. Careful patient selection, technical expertise, and posttransplant oncologic surveillance is critical for successful long-term outcomes.
