Recent Advances in PDD and PDT for Malignant Brain Tumors

Abstract

Photodynamic Diagnosis (PDD, Fluorescence Diagnosis) and Photodynamic Therapy (PDT) were performed for malignant brain tumor patients. We have treated 250 patients with PDD during surgery and also 63 patients with PDT in our hospital. The rate of total removal of tumor tissues increased by using PDD (fluorescence diagnosis) during surgery and many malignant glioma patients survived for long time by treatment with PDT. PDD and PDT were very effective for malignant brain tumor patients from our experiences.
