Abstract

BACKGROUND:

Carcinoma of the ampulla of Vater is uncommon. This study aimed to clarify predictors of survival for ampullary adenocarcinoma and to identify characteristics of its two major pathological subtypes.

METHODS:

Medical records were reviewed for 86 patients who underwent curative resection for ampullary adenocarcinoma between 2000 and 2012 at 12 principal hospitals in Kagawa, Japan.

RESULTS:

Resection was most common among 75-79-year-old patients. Actuarial 1-, 3-, and 5-year postoperative survival rates for ampullary adenocarcinoma were 90%, 72.3%, and 69.1%, respectively. Preoperative biliary drainage; serum CA19-9 and total bilirubin levels; pathological grade; perineural, vascular, pancreatic, and duodenal invasion; nodal metastasis; UICC-T stage; and pancreatobiliary subtype were predictors of poor survival. An elevated serum CA19-9 level; an elevated total bilirubin level; lymphatic, vascular, perineural, and pancreatic invasion; and advanced overall tumor stage were more common in patients with pancreatobiliary-type tumors than in patients with intestinal-type tumors. Additionally, pathologic subtype analysis showed that each subtype had distinct prognostic factors.

CONCLUSIONS:

Preoperative elevated serum CA19-9 and total bilirubin levels are prognostic factors for ampullary adenocarcinoma, and are both associated with pancreatobiliary-type tumors. Surgeons should be aware of these factors because pancreatobiliary-type adenocarcinoma is aggressively invasive and is associated with poor survival.
