The authors investigated the expression of mucins in ampullary cancer. Methods. Muc1 and muc2 expressions were examined using immunohistochemistry. Tissue samples were obtained from 32 patients with ampullary cancer who underwent resection at yamagata university hospital, japan. The authors classified the cases with ampullary cancer into 2 subtypes—pancreatobiliary type (pb type) and intestinal type (i type)—using h&e, muc1, and muc2 staining. order viagra Then, the authors made a comparison of the clinicopathologic data of the 2 subtypes.

The pb-type group had significantly worse histopathologic characteristics than the i-type group in nodal involvement (pb type 57% vs i type 22%; p =. 04), perineural invasion (pb type 50% vs i type 17%; p =. 04), duodenal invasion (pb type 100% vs i type 33%; p =. 01), and pancreatic invasion (pb type 71% vs i type 33%; p =. 03).
