Abstract
Photodynamic therapy (PDT) was performed on 11 cases of recurrent cerebral glioma, including 3 cases of recurrent glioblastoma, 7 of recurrent anaplastic astrocytoma, and 1 recurrent ependymoma. Hematoporphyrin derivative (HPD) was administered intravenously at a dose of 4 - 7 mg/kg 5 - 24 hours before the operation. All patients underwent a craniotomy with a nearly radical excision of the tumor following which the tumor bed was irradiated with 630 nm laser light emitting either an argon pumped dye laser or frequency double YAG pumped dye laser for 30 to 80 minutes with a total dose of 50 J/cm2 (n equals 1), 100 J/cm2 (n equals 2), 200 J/cm2 (n equals 7), and 300 J/cm2 (n equals 1). The temperature was kept below 37 degree(s)C by irrigation. Two patients underwent postoperative radiotherapy. There was no evidence of increased cerebral edema, and no other toxicity by the therapy. All patients were discharged from the hospital within 15 days after surgery. We conclude that PDT using 4 - 7 mg/kg of HPD and 630 nm light with a dose of up to 300 J/cm2 can be used as an adjuvant therapy with no additional complications. Adjuvant PDT in the treatment of recurrent glioma is better than simple surgery.
