Abstract:Photodynamic therapy (PDT) is a photo-stimulating chemotherapy for malignant tumors, which has been applied to the clinical treatment of biliary cancers, with effective improvement in the quality of life and the survival of patients. Based on the existing clinical evidence, Digestive Endoscopy Branch of Chinese Medical Association, Expert Committee of Tumor Photodynamic Therapy of the Chinese Society of Clinical Oncology, and Expert Committee of Tumor Photodynamic Therapy of Chinese Anti-Cancer Association organized relevant experts to conduct in-depth discussions on all aspects of the clinical application of PDT, including the indications, preoperative preparation, parameters setting, prevention and treatment of complications and postoperative follow-up, and reach 21 consensus recommendations. This consensus can provide a reference for clinicians and researchers to standardize the application of PDT.
