254 Background: Ampullary carcinoma is a rare malignancy. Despite radical resection, survival rates remain low with high rates of local failure. To define the role of radiation therapy and chemotherapy with surgery, we performed a single institution analysis of treatment- related outcomes. METHODS: A retrospective analysis was performed of all patients undergoing potentially curative therapy for adenocarcinoma of the ampulla of Vater at Duke University Hospitals between 1975 and 2009. Local control (LC), overall survival (OS), disease-free survival (DFS), and metastases-free survival (MFS) were estimated using the Kaplan-Meier Method. RESULTS: One hundred thirty-seven patients with ampullary carcinoma underwent potentially curative pancreaticoduodenectomy. Sixty-one patients undergoing resection received adjuvant (n= 43) or neoadjuvant (n=18) radiation therapy with concurrent chemotherapy (CRT). Patients receiving radiotherapy were more likely to have poorly differentiated tumors. Median radiation dose was 50 Gy. Median follow up was 8.8 years. Of patients receiving neoadjuvant therapy, 67% were downstaged on final pathology with 28% achieving pathologic complete response. Three-year local control was significantly improved in patients receiving CRT (88% vs. 55% p= 0.001) with trend toward a 3-year OS benefit in patients receiving CRT (62% vs. 46% p=0.074). Despite this, there was no significant difference in 3-year DFS (66% CRT vs 48% surgery alone p=0.09) or MFS (69% CRT vs 63% surgery alone p=0.337). CONCLUSIONS: Long term survival rates are low. Local failure rates are high following radical resection alone and improved with CRT. Despite more adverse pathologic features in patients receiving CRT, survival outcomes were at least equivalent with a trend toward statistical significance. Given the patterns of relapse with surgery alone and local control benefit in patients receiving CRT, the use of chemoradiotherapy in selected patients should be considered. No significant financial relationships to disclose.
