Abstract
Gene therapy is a promising modality for the treatment of soft tissue malignancies. Our laboratory has developed a novel technique of gene transfer using microvascular free flaps that addresses many of the current barriers preventing gene therapy from achieving widespread clinical use. Our previous work has demonstrated our ability to transduce free flaps with an adenovirus encoding the reporter gene lacZ. In this current study, we show that microvascular free flaps can be transduced with an adenovirus encoding the angiogenesis inhibitor endostatin with high levels of local flap expression. These transduced free flaps were able to serve as "biologic pumps" and were able to secrete endostatin into the serum as demonstrated by enzyme-linked immunosorbent assay. This form of "biologic brachytherapy" could provide a novel approach for the continuous delivery of therapeutic genes to a localized area while avoiding many of the practical obstacles currently limiting gene therapy.
