Diagnosis and treatment of cholangiocarcinoma in Italy: A Delphi consensus statement

Background: Clinical practice guidelines for the management of cholangiocarcinoma (CCA)/biliary tract cancer recommend genomic profiling to guide treatment decisions. Variable access to such profiling across Italy means many oncologists are unfamiliar with when and how to conduct genetic testing and prescribe targeted treatments. Methods: A Scientific Board of Italian oncologists who treat CCA (the authors) developed recommendations, based on recent clinical evidence, for using molecular testing in diagnosing, assessing, and treating CCA in Italy. The Delphi process was used to reach consensus on these recommendations among 38 Italian oncologists. Consensus was considered to be met if >= 66.7 % of the panel agreed or strongly agreed with each statement. Findings: Consensus was reached on 28 statements across four themes: (1) epidemiology and risk factors; (2) diagnosis, including molecular diagnosis; (3) treatment selection; and (4) treatment safety. Interpretation: These recommendations should aid Italian clinicians in selecting appropriate treatment options for their patients.
