The results of the current study were from a multicenter trial performed at the following medical institutions. The authors would like to express their gratitude to all the cooperating surgical oncologists who were at the institutions at the time the study was performed:

In this multicenter randomized trial, the efficacy of combination chemotherapy using 5-fluorouracil, doxorubicin and mitomycin C (arm A) was compared with that of 5-fluorouracil alone (arm B) in 81 patients with nonresectable carcinomas of the pancreas or biliary tract. There were no significant differences between treatment arms regarding the median time to progressive disease, median survival time, palliative effects or toxicities. It was concluded that combination chemotherapy is feasible but cannot be recommended.

A case of lymphoepithelial cyst in the pancreas was reported. A 64-year-old man without any specific complaints was found to have a cystic lesion in the anterior portion of the pancreas, as revealed by ultrasonography of the abdomen at an annual medical examination in 1988. This was dissected easily from the pancreas. Histologically, it was diagnosed to be a benign lymphoepithelial cyst in the pancreas. Cysts of this type are rare, and their histogenesis is also not well understood.
