Le morte du tumour: histological features of tumor destruction in chemo-resistant cancers following intravenous infusions of pathotropic nanoparticles bearing therapeutic genes.

The pathotropic targeting of therapeutic nanoparticles to cancerous lesions is an innovative concept that has recently been reduced to practice in clinical trials for the treatment of metastatic cancer. Previously, we reported that intravenous infusions of Rexin-G, a pathotropic nanoparticle (or vector) bearing a cyto-ablative construct, induced tumor regression, reduced tumor burden, and improved survival, while enhancing the overall quality-of-life of patients with otherwise intractable chemotherapy-resistant cancers. In this report, we describe the major histopathological and radiologic features that are characteristic of solid tumors under the destructive influences of Rexin-G administered as a single therapeutic agent.
