Ampullary carcinoma (AC) is a relatively rare entity often managed as a biliopancreatic carcinoma. AC has a better prognosis than peri ampullary tumors after resection, but more than a third of patients relapse. Factors predictive of recurrence are controversial, mainly because the relevant studies are very small or also included non AC tumors. There are no guidelines on the use of adjuvant or neoadjuvant chemotherapy. The aim of this study was to identify prognostic factors for recurrence after AC resection in a large multicentric cohort, and to establish a simple, practical, predictive score for recurrence in order to guide multidisciplinary decisions.
