ABSTRACT

Objective To observe and evaluate clinical therapeutic effect of photodynamic therapy (PDT) on malignant tumor. Methods 20 patients of malignant tumors of different nature and different stages were subjected to PDT or PDT-predominant comprehensive therapy. All the patients were followed-up, and the clinical results were analyzed. Results Among these patients, 3 tumors at early stage showed complete remission (CR), and no relapse was found in the follow-up period. Among the 17 cases with tumors in advanced stage, CR was seen in 9 cases, PR in 8, and 3 patients died of causes other than PDT after 1-6 months of follow-up. Conclusion PDT shows a curative effect on malignant tumors in early stage, and fairly good therapeutic effect on those in advanced stage. It is one of the optional treatments for malignant tumors.
