Abstract
Background and Aims:
The prognosis for patients with ampulla of Vater cancer is better than other periampullary cancers. The aim of the present study is to determine the clinicopathologic factors predictive of survival and recurrence in patients with ampulla of Vater cancer.
Material and Methods:
From 1991 to 2008, we identified and reviewed 78 patients with ampulla of Vater cancer retrospectively. Clinicopathologic factors possibly influencing survival and recurrence were statistically analyzed.
Results:
Pancreaticoduodenectomy was performed in 68 patients and 2 patients underwent transduodenal ampullectomy. Hospital mortality was 2.6%. The 5-year survival rates following resection were 59.9%. Univariate analysis for overall survival revealed that total bilirubin greater than 5mg/dl, ulcerative tumors, differentiation, and pancreatic invasion were significant prognostic factors. Recurrence occurred in 31 patients. Univariate analysis for disease-free survival revealed that total bilirubin greater than 5mg/dl, preoperative biliary drainage, tumor differentiation, and stage were statistically significant. Multivariate analysis revealed that tumor differentiation was an independent prognostic factor for recurrence. The presence of lymph node metastasis did not affect overall survival significantly in this study. However, two or more metastatic lymph nodes significantly affect disease-free survival.
Conclusions:
Pancreaticoduodenectomy is a safe surgical procedure with acceptable long-term survival for ampulla of Vater cancer. Pancreaticoduodenectomy with lymph node dissection might control lymph node spread and enhance survival outcome.
