  • Beschreibung: <jats:title>Significance</jats:title> <jats:p> Inflammatory breast cancer (IBC) is defined clinically and pathologically. Dermal lymphatic invasion is typical but is neither necessary nor sufficient for diagnosis; sentinel lymph node biopsy is contraindicated, challenging multidisciplinary management with upfront chemotherapy, surgery, and postoperative radiotherapy. Here we applied a ligand-directed “theranostic” (a combination of therapeutic and diagnostic) enabling platform to target IBC based on adeno-associated virus/phage (AAVP)- <jats:italic>Herpes simplex</jats:italic> virus thymidine kinase type-1 ( <jats:italic>HSVtk</jats:italic> ) particles displaying ligands to cell surface-associated 78-kD glucose-regulated protein (GRP78). In a suite of preclinical models and human tumor samples, we show simultaneous noninvasive molecular serial PET/CT imaging and targeted suicide transgene therapy. This study shows that a tumor-specific promoter, human <jats:italic>GRP78</jats:italic> ( <jats:italic>hGRP78</jats:italic> ), can drive the expression of an imaging/suicide transgene in IBC and aggressive breast cancer in vivo. </jats:p>
