Glycosylated Hematoporphyrins: A New Approach in Cancer Phototherapy?

Abstract
Although the phenomenon is not fully understood, it is now well established that some porphyrins have a natural tendency to concentrate more in malignant tumors than in normal tissue. This property has found an application in photodynamic therapy of cancers in which a tumor, with an enriched concentration of porphyrin, can be selectively destroyed by applying light, without damage to surrounding cells.1
