Four cases of anaplastic carcinoma of the pancreas or biliary tract were studied clinicopathologically and immunohistochemically. All four cases were intermediate cell type and contained a minimum amount of microscopic foci of differentiated glandular adenocarcinoma. Argyrophilic tumor cells were not seen in any of the four tumors. Immunohistochemically, no(More)

Surgical treatment of the pancreatic cancer is currently unsatisfactory. By using anti-K,H,N-ras monoclonal and anti-myc polyclonal antibodies, paraffin-embedded tissue specimens of the carcinoma in digestive organs were immunohistologically studied. Then, the incidence of expression of these oncogenes and correlative studies of survival rate and disease(More)
