Objective: Long ranging responses after ALA/PDT of glioma patients suggest additional mechanisms of tumor control apart from the limited photochemical destruction of the tumor. To determine whether ALA/PDT causes local stimulation of anti-tumoral immunity, we have studied the effects of PDT[for full text, please go to the a.m. URL]
