Is Duodenal Invasion a Relevant Prognosticator in Patients Undergoing Adjuvant Chemoradiotherapy for Distal Common Bile Duct Cancer?

Histologic differentiation and tumor size were significant prognostic factors predicting overall survival, whereas duodenal invasion was not. This finding suggests the need for further refinement in tumor staging.
