Carcinoid of the rectum risk stratification (CaRRs): A strategy for preoperative outcome assessment
Neoplasm Recurrence, Local
Outcome Assessment (Health Care)
Poor prognostic features of rectal carcinoids include: large size, deep invasion, LVI, and elevated mitotic rate. The CaRRS score incorporates these features and accurately predicts outcome. Because the CaRRS score is based upon values available on pre-operative biopsy, it can identify patients with very favorable prognosis as well as those with poor prognosis that may benefit from additional staging or surveillance.
