Abstract
A method of administering an anti-tumor compound to a subject is disclosed. The method includes administering to a subject liposomes having sizes predominantly in the range 0.05 to 0.12 microns, and containing an anti-tumor compound in liposome-entrapped form, a surface coating of polyethylene glycol chains, at a surface concentration thereof sufficient to extend the blood circulation time of the liposomes severalfold over that of liposomes in the absence of such coating, and surface-attached antibody molecules effective to bind specifically to tumor-associated antigens present at the tumor site. One liposome composition includes doxorubicin in entrapped form, and, on the liposome surface, a monoclonal antibody against highly proliferating cells in a lung squamous cell carcinoma.
