Development of a New Immunochemistry Method Using Antibodies of Proteins Related Bile Duct Cancer

South Korea240 participantsStarted 2018-11-01

Plain-language summary

The sensitivity of brushing cytology used to distinguish the cause of biliary strictures is low and clinical usefulness is not secured. The aim of this study was to develop a new differential staining method for cytology which is difficult to differentiate by the conventional staining method using biliary cancer related protein expressed only in bile duct cancer.
