The radiation-inducible chimeric genetic construct Egr-TNF alpha introduced
into human xenografts produces cytotoxicity of infected tumor cells result
ing in tumor growth inhibition. The interaction between Egr-TNF and radiati
on is selectively cytotoxic for the tumor microvasculature resulting in vas
cular thrombosis and tumor necrosis. Gene therapy combined with radiation t
herapy offers great potential for the treatment of localized human cancers.
