Which of the following statement(s) is/are true about bile duct cancers?

E. None of the above is true.

DISCUSSION: Most bile duct cancers are discovered after they are incurable, and only a tiny subset of resected proximal lesions are cured. The more distal the lesion, the more likely is resection to achieve cure (e.g., approximately 30% 5-year survival for periampullary lesions as compared with 0% to 10% for hilar lesions). The use of adjuvant or primary radiation remains controversial because of the heterogeneity of the patient populations on which this modality has been used. Because of the localized nature of this disease it would seem that transplantation would produce favorable results; however, this has not been the case.
