Objective:To investigate the potential value of PDT(photodynamic therapy)in the treatment of rectal cancer by reviewing the diagnosis and treatment process of a patient with advanced rectal cancer who lost the opportunity of surgery.Methods:Select the case data of a patient receiving photodynamic therapy in our hospital,and analyze the photodynamic mechanism safety and efficiency,and discuss the efficacy of photodynamic therapy.Results:After the patient received photodynamic therapy,re-examination of the endoscopy showed that the intestinal cavity was smoother than before,the bowel was difficult,and the symptoms of blood in the stool improved.Conclusion:Photodynamic therapy can be used as a radical or palliative treatment for clinical tumor treatment.Because of its advantages of minimally invasive,tissue-specific,repetitive and synergistic radiotherapy and chemotherapy,it plays an important role in early or middle-advanced colorectal cancer and is worthy of clinical promotion.
