Neoadjuvant photodynamic therapy as a new approach to treating hilar cholangiocarcinoma

Abstract

Neoadjuvant PDT for hilar CC is a low-risk procedure with efficient selective destruction of the superficial 4 mm layer of bile duct tumor without complications exceeding series without neoadjuvant PDT. Neoadjuvant PDT should be evaluated prospectively to determine whether it reduces the rate of local disease recurrence after potentially curative resection.
