Noteworthy clinical case studies in cancer gene therapy: tumor-targeted Rexin-G advances as an efficacious anti-cancer agent.

The advent of pathotropic (disease-seeking) targeting technology has ushered cancer gene therapy across the threshold of history, marking the beginning of a new epoch of medical praxis. For the first time, clinical oncologists can reach beyond the finest of catheters, beyond the reach of the most gifted surgeons, to the very fabric of metastatic disease in an effort to halt the progression and turn the tide of otherwise intractable cancers. The enabling molecular biotechnologies embodied in the leading tumor-targeted agent, Rexin-G, and its timely development as a safe and effective anti-cancer drug - from oncogene discovery and target validation, to molecular engineering of the core nanotechnologies, to the first clinical proofs-of principle, confirmatory trials, expanded access programs, and accelerated regulatory approvals - have been extensively documented in the medical literature. Therefore, this paper represents a final chapter, highlighting a series of noteworthy cases studies in the emergent field of targeted genetic medicine: case studies which, in and of themselves, reveal vital and important aspects of the molecular-genetic bio-pharmacology, advanced clinical protocols, refinement of patient monitoring, expanding treatment options, and strategic medical approaches to patient care that exemplify and thereby extend the established principles of pathotropic targeting and cancer gene therapy to a new generation of clinical practitioners.
