In the New classification of bile duct cancer, Ampullary adenocarcinoma (AA)is not belonging to CCA.
But as recent as a couple months ago,when I read about CCA, AAis still mentioned together in the articles of treating CCA.
I do not see AA will have a large population to support a separated web site on its own. The treatment plans of AA are more or less the same as CCA but your chance of survival is better than those,like me for example,for a longer period.
