    Abstract:
    BACKGROUND/AIMS: The prognosis after curative resection for patients with carcinoma of the papilla of Vater is relatively better than that for other peripancreatic cancer. However, prognostic factors after resection of the carcinoma have not been identified. METHODOLOGY: From 1983 to 1999, 16 patients with carcinoma of the papilla of Vater underwent standard pancreatoduodenectomy and dissection of regional lymph nodes. We followed the patients for 63 days to 17 years (median, 27 months) and analyzed clinicopathologic variables in relation to prognosis. RESULTS: The survival rate at 5 years was 50.5%. The morphologic factors predicting poor outcome were macroscopic ulcer formation and microscopic pancreatic, venous, or perineural invasion. Tumors with ulcer formation tended to infiltrate into the duodenum and pancreas, but not into veins or the perineural space. Eight of 16 patients died due to recurrence of the cancer; liver metastasis (n = 6) or peritoneal dissemination (n = 2). CONCLUSIONS: Patients with carcinoma of the papilla of Vater demonstrating ulcer formation or invasion into the pancreas, vein, or perineural space may benefit from adjuvant therapy to reduce the risk of liver metastasis. Careful observation is essential for liver metastasis or peritoneal dissemination after surgery; especially in patients with ulcer formation or venous invasion.
