Porphyrin Localizing Phenomena
The use of the porphyrin product HPD1 for tumor localization (1,2) and therapy (2–5) has been described. One report on an analysis of HPD appeared in 1980 (6) and other such reports are contained in this book. In order to characterize the events leading to tumor localization by HPD, it will be necessary to delineate active components in the product, the nature of any porphyrin transformations associated with the localization process and loci of binding of localized fluorescent porphyrins within the tumor cell.
