label_lc: perihilar bile duct cancer clinical tnm finding v7
description: "A clinical finding about one or more characteristics of perihilar bile duct cancer, following the rules of the TNM AJCC v7 classification system.  The clinical evaluation usually depends on the results of duplex ultrasound, computed tomography, and magnetic resonance cholangiopancreatography (MRCP).  The biliary extent of disease is assessed with percutaneous transhepatic cholangiography or MRCP.  Clinical staging also may be based on findings from surgical exploration when the main tumor mass is not resected.  (from AJCC 7th Ed.)"
