Purpose: The aim of this study was to identify prognostic factors in patients undergoing pancreatoduodenectomy with lymphadenectomy for ampullary carcinoma.

Methods: The records of 46 consecutive patients with ampullary carcinoma who underwent pancreatoduodenectomy from 1988 through 2006 were retrospectively reviewed.

Results: A 98% rate of potentially curative (R0) resection was achieved. There was no 30-day mortality. Overall 5-year survival rate was 64%.0 Univariate analysis revealed that T3 and T4 tumor (ie, pancreatic parenchymal invasion) (P<0.001), lymph node metastasis (P=0.01), and perineural invasion (P<0.001) were significant predictors of poor prognosis. Furthermore, perineural invasion was found to be a significant independent predictor of poor prognosis by multivariate analysis (P=0.024).

Conclusions: Pancreatoduodenectomy with lymphadenectomy for ampullary carcinoma is a safe surgical procedure with an acceptable cure rate. The presence of perineural invasion may be useful for predicting poor prognosis in patients with ampullary carcinoma who undergo potentially curative resection.
