Photodynamic therapy in patients with hilar cholangiocarcinoma
Extrahepatic bile duct cancer is one of those pathologies in which about 70% of patients due to the prevalence of the tumor process can not receive radical treatment, which determines the need for active implementation of methods that allow, while maintaining a satisfactory quality of life of patients, to increase survival rates. Due to the peculiarities of localization and development of malignant tumors of the extrahepatic bile ducts, as well as the nature of the disease, special importance in the treatment of these patients is given to various methods of external or internal bile removal and on the second stage of treatment can be considered local or systemic methods of exposure. Currently, as a method of local therapy in patients with unresectable extrahepatic bile duct cancer, various options of radiation therapy, radiofrequency and microwave ablation, photodynamic therapy are used. This article presents a literature review covering the feasibility, safety and efficacy of photodynamic therapy in patients with Klatskin tumor.
