Abstract

BACKGROUND/AIMS:

The prognostic factor(s) of carcinoma of the ampulla of Vater were analyzed retrospectively and the significance of lymphadenectomy around the superior mesenteric artery and para-aortic region on the clinical outcome was evaluated.

METHODOLOGY:

From 1985 to 2008, 34 carcinomas of the ampulla of Vater patients who underwent pancreaticoduodenectomy with curative intent were analyzed with respect to tumor extent, operation method and prognosis.

RESULTS:

Overall 5-year survival was 52.6%. On multivariate analysis, lymph node metastasis, pancreatic invasion, venous invasion, perineural invasion and lymphadenectomy around the superior mesenteric artery were the significant prognostic factors. However, the dissection of para-aortic lymph nodes had no substantial survival benefit. Compared with the duodenal cancer, the prognosis for carcinoma of the ampulla of Vater was significantly worse although no differences in clinicopathological characteristics of patients were observed.

CONCLUSIONS:

Lymph node metastasis, pancreatic invasion, venous invasion, perineural invasion, and lymphadenectomy around the superior mesenteric artery are important prognostic factors. Pylorus-preserving pancreaticoduodenectomy, with lymphadenectomy around the superior mesenteric artery without dissection of para-aortic lymph nodes is recommended as optimal surgery. Though the treatment results were worse than that of duodenal cancer, curative operation should be performed, regardless of site of origin.
