Background And Aims: In unresectable biliary tract cancers, the management of biliary obstruction is often the first step before introduction of chemotherapy. Our aim was to study the predictive factors of chemotherapy initiation after biliary drainage in a series of patients presenting with advanced biliary tract cancer and obstructive jaundice.
Methods: Data of all patients treated for unresectable biliary tract cancer with initial biliary obstruction requiring a drainage in six institutions, from January 2009 to January 2019, were retrospectively collected.
