In this paper we describe the efficacy of the liposomal-AlClPc (aluminum-chloro-phthalocyanine) formulation in PDT study against Ehrlich tumor cells proliferation in immunocompetent swiss mice tongue. Experiments were conduced in sixteen tumor induced mice that were divided in three control groups: (1) tumor without treatment; (2) tumor with 100 J/cm(2) laser (670 nm) irradiation; and (3) tumor with AlClPc peritumoral injection; and a PDT experimental group when tumors received AlClPc injection followed by tumor irradiation. Control groups present similar macroscopically and histological patterns after treatments, while PDT treatment induced 90% of Ehrlich tumor necrosis after 24 h of one single showing the efficacy of liposome-AlClPc (aluminum-chloro-phthalocyanine) mediated PDT application, on the treatment of oral cancer.
