Endosonographic and Histopathological Staging of Extrahepatic Bile Duct Cancer: Time to Leave the Present TNM-Classification?

Abstract

Most adaptations made by the sixth edition of the TNM classification accommodate to the endosonographic and most of the histopathological findings as demonstrated in our study. In contrast to the new edition, however, our findings suggest to combine T2- and T3-staged tumors into one single class leading to clarification, and improved reproducibility of histopathological staging.
