Cholangiocarcima is a devastating illness with poor long-term survival. The diagsis and treatment of cholangocarcima is becoming increasingly important, particularly with the increasing incidence of hepatocellular carcima, ather primary liver tumour. Since the diagsis, treatment, and progsis of the two similar malignancies vary tremendously, a thorough understanding of cholangiocarcima is vital for any practitioner dealing with this patient population. The diagsis and treatment of patients with this disease requires input from nearly every specialist in cancer care: pathologists, diagstic radiologists, hepatologists, endoscopists, surgical oncologists, medical oncologists, radiation oncologists, and interventional radiologists, who all play a very active role in the management of this disease process. The intent of this book is to provide an overview of the entire disease process, from the diagsis through imaging and pathology, to the clinical care of patients pre- and post-treatment, to primary oncologic interventions.
