Abstract
The efficacy of light activated therapy treatment is enhanced by stimulating the immune system of the patient substantially above a normal level. Abnormal tissue that is destroyed by the light activated therapy releases factors that stimulate the immune system, leading to systemic reductions in abnormal tissue (i.e., reduction beyond the region treated using light). By further stimulating the immune system using an anti-CTLA-4 antibody, the systemic destruction of abnormal tissue is enhanced.
