Welcome to the forum. The pathologist is only looking a slices of the tumor, it's possible for them to not get a section with active cancer in it. With the tumor markers for tc being elevated I would say that the BEP is not being wasted. We have others on this site who know far more then I do and I'm sure they will post some very helpful information.
