The most appropriate treatment for Klatskin tumor(KT)with a curative intention is multimodal therapy based on achieving resection with tumour-free margins(R0resections)combined with other types of neoadjuvant or adjuvant treatment(the most important factor affecting KT survival is the possibility of R0 resections,achieving 5-year survival rate of 40%-50%).Thirty to forty percent of patients with KT are inoperable and present a 5-year survival rate of 0%.In irresectable non-disseminated KT patients,using liver transplantation without neoadjuvant treatment,the 5-year survival rate increase to 38%,reaching 50%survival in early *** selected cases,with liver transplantation and neoadjuvant treatment(chemotherapy and radiotherapy),the actuarial survival rate is 65%at 5 years and 59%at 10 *** conclusion,correct staging,neoadjuvant treatment,living donor and priority on the liver transplant waiting list may lead to improved results.
