Prostate cancer is one of the most common types of cancer affecting men in the U.S. and is the second leading cause of cancer death among men, after lung cancer. Among the most recent treatment strategies being tested against prostate cancer is gene therapy, in which a gene product intended to destroy the tumor cells or to stimulate the patient’s immune system to fight the cancer is delivered to the tumor, typically using a viral delivery vector. The most common approach uses an adenovirus as the delivery vector and has been shown to be quite safe.
However, it is still not clear which genes, viral vectors, or strategies are optimal to ensure targeted delivery of the genes to the tumor cells, and uptake by the tumor, to achieve the most effective, most potent, and safest treatment that can lead to a cure for prostate cancer. Stefan Kochanek, from the University of Ulm, Germany, and Bernd Gänsbacher, from the Technical University of Munich, Germany, present their views on the need for developing and testing new and innovative approaches in the editorial entitled, “Prostate Cancer Gene Therapy: Attempts to Innovate.”
Three review articles in the issue explore various aspects of this evolving field and advances that will make it possible to translate new gene therapy techniques from research to testing in human patients. Ellen Schenk and colleagues from Erasmus Medical Center, The Netherlands, and Uppsala University, Sweden, representing the GIANT FP6 Consortium, review current clinical experiences and progress toward the development of adenovirus-mediated gene therapy in the review article entitled, “Clinical Adenoviral Gene Therapy for Prostate Cancer.”
Norman Maitland and coauthors from University of York, U.K., Uppsala University, Sweden, and Erasmus Medical Center, The Netherlands, on behalf of the GIANT FP6 Consortium, emphasize the need for laboratory models that more closely mirror human tissues in the article entitled, “Gene Transfer Vectors Targeted to Human Prostate Cancer: Do We Need Better Preclinical Testing Systems?”
Jeroen de Vrij and colleagues from Leiden University Medical Center and Erasmus Medical Center, The Netherlands, and from Got-a-Gene, in Kullavik, Sweden, also representing the GIANT FP6 Consortium, summarize recent advances in adenovirus technology and present state-of-the-art and future prospects for adenoviral vector-based gene therapy in the article entitled, “Adenovirus-Derived Vectors for Prostate Cancer Gene Therapy.”
“Achievement of the full potential of gene transfer technologies will depend upon understanding the basic concepts of carcinogenesis in the prostate,” says Bernd Gänsbacher, MD, PhD, Deputy Editor of Human Gene Therapy and Director, Institute for Experimental Oncology, Technical University of Munich, Germany.
Human Gene Therapy, the Official Journal of the European Society of Gene and Cell Therapy, British Society for Gene Therapy, French Society of Cell and Gene Therapy, German Society of Gene Therapy, and five other gene therapy societies is the authoritative peer-reviewed journal published monthly in print and online that presents reports on the transfer and expression of genes in mammals, including humans. Related topics include improvements in vector development, delivery systems, and animal models, particularly in the areas of cancer, heart disease, viral disease, genetic disease, and neurological disease, as well as ethical, legal, and regulatory issues related to the gene transfer in humans. Tables of content and a free sample issue may be viewed online.
