This commentary describes recent progress in the use of porphy~ ns for tumor detection and therapy. In 1961, Lipson et al.[l] described porphyrin localization in human tumors following injection of a product termed “HPD”(hematoporphyrin derivative), synthetically derived from hematoporphyrin (Fig. 1). Although accumulation of porphyrins at neoplastic loci had been described in 1924 [2], there were few reports (summa~ zed in Ref. 3) on the phenomenon prior to the work of Lipson. HPD was found to be a superior localizer but was, initially, something of a laboratory curiosity. Developments in instrumentation, described below, have now made feasible use of HPD in the clinic for both tumor localization and therapy. Cells that have accumulated porphyrins are photosensitized, ie subsequent exposure to light has cytotoxic consequences. An excess production of endogenous porphyrins occurs in a pathologic state called porphyria [4], which is associated with substantial light-catalyzed damage to skin and other tissues. If porphyrin a~ umulation could be targeted ti'CH,
